Illuminating Lincoln: Lighthouse - map and map files

So far, I have tested with my iPad and my Android phone.  On Android, use the .kml file with Google Earth and use the .gpx file with a mapping app like OsmAnd.   In iOS, try the .kml file first.  Tweet pics when you locate them using the #lightbulbchallenge.

For more information about the project see the Journal Star article and the Lighthouse website.

Edit: A better article about the project on the Journal Star site.

Kitchen Garden, Visit from a Marine, and Fight Club

Terraces + raised bed = ~900 sq. ft. 

Kitchen Garden

Last year, I expanded the raised herb garden by terracing the slope. This gave me four ~16'x2' beds separated by old railroad ties.  The terrace beds have good drainage and the ties give me a place to walk such that I never have to step on the soil. Consequently, it doesn't require any digging before planting really, though I did dig in my compost and some leaf mold in last fall.  The soil, like much of that in eastern Nebraska, is clumpy because of the clay, but with regular applications of compost and leaf mulch combined with a multitude of earthworms, I expect rich loamy soil in time.
Just like the picture
on the seed package. 

This month we also used the broken concrete from the back patio to make stepping stones from the front walk to the garden, then on around to the patio.  This makes it easy for me to dart from the kitchen to the garden with no shoes. Additionally, it saves us from hauling the concrete to the landfill or somesuch.

The radishes are "French Breakfast" and have a milder flavor that other varieties. The grow quickly and I've been planting a few every two weeks to space out the harvest. I chopped up the radish tops, sauteed them lightly, and had them for dinner atop brown rice with a couple of eggs.  My folks have chickens who patrol the farm for grasshoppers and other bugs, as well as earn their keep turning the compost piles. In turn, they produce the most delicious eggs which my mother generously drops by the house when she's in town.

A Visit from Corporal Brown

Nick treated us with a visit this month and we hosted a small garden party.  It was a bit early and the weather was windy and chill in the  morning, but by late afternoon when people began to arrive, the weather had warmed and it was quite pleasant.
4x4s and cinder blocks provided expanded fire pit seating.
This view will change substantially this year.
The Founders All-Day IPA proved popular. 

My little darlings. 

Solomon's Seal and the last tulip graced the buffet table.

After most everyone left, Lyle ventured forth. He prefers pond water to his kitchen bowl.

Lacerations and Punctures

Speaking of the three-legged wonder, there's a new member at fight club - we'll call him Fangs. I suspect a feral tom cat from the severity of the wounds Lyle is bringing home.  The first time, it wasn't too deep, but the second round merited a visit to the vet.  Fangs digs into the right side of Lyle's neck, then shreds his belly with his back claws.  It isn't pretty and Lyle's new name should probably be "Scarbelly". 

In response, we tried to keep Lyle in, but if you've ever heard him yowl, you know it's impossible. So, we made a short fence using chicken wire.

This wouldn't contain most cats, but Lyle doesn't have much of a vertical jump, so it kept him in so long as he had
supervision.  If you went inside or put him out at night, he found ways to get under the fence. 
The wire didn't hold him for long, but for a couple of weeks we kept him contained and his wounds healed up. This last weekend, however, he ran into Fangs again and again has neck wounds.  This time, no trip to the vet.  Instead, I stocked up on vet supplies and have been taking care of it and things seem to be healing nicely.  The real challenge is how to keep Lyle from running into Fangs in the future. 

Although a bit high-maintenance, the rare short-legged tripod feline
makes it all worth it when he greets me at the door and
insists on post-work lap time.

Puddle to small water garden

EDIT: If you cannot see the images, there is a collection in the Pond 2015 folder. It was brought to my attention that the images were not showing. 

It's hard to believe it's been so many months since a post. I've been intending to write a few things up, but didn't get to it, so I'll start with the puddle to pond project.

Before I ever rode bicycles with any real enthusiasm, I identified as a gardener.  A particular dear friend and I used to maintain a subtle competition focused on who could give the other the best wine-infused garden tour and remember all the Latin monikers.  In fact, I used to aspire to making Lincoln's garden tour.  In any case, this year I'm letting the bug blossom (intended mixed metaphor).

When I moved to the cottage, the extensive shaded back yard and lovely south-facing side yard distracted me from the many many house-buyer-deterring issues I should have perhaps given more consideration.  There was also a small, pre-formed pond liner serving as an optimal mosquito breeding facility near the alley.  Thank goodness for progeny.  Dearest Erik dug it up, cleaned it out, and dug it in again near the patio. I planted around it, tried to defend fish against the racoons, watched birds bathe, and generally enjoyed the life and sound even a modest puddle brings to the garden space.

This year, however, general happiness coupled with an improved post-PhD budget has seen me fully regress into the gardener lifestyle and this year kicked off with a water feature makeover - along with getting those radishes and snap peas in on time.  The photos below begin with the puddle after the plants have been extracted and the site is ready for digging.  The gent is also digging into a favorite project, but don't let all the flash distract you from the classy worn wheel barrow and luscious soil.
Project day

Plants removed. Prepare to dig.

This is going to take a while.
One of the mistakes I've made in past water garden projects is not making the initial shelves deep enough.  This time, I'm taking a lot of care.  I want plenty of room to do something creative so the liner won't be visible along with space for plants.  A critical aspect of the shelf, however, is that it be level all round the pond. For this pond, it was small enough to just use a level with a long board.  If the pond were bigger, I would use a clear length of tubing and fill it with water.  I suppose a laser level might be pretty useful as well.

Is the lower shelf level?

Booyah! First try.

 One of the constraints of this pond was that materials found on the property needed to be recycled. It wasn't going to be one of those... I built this dream pond and it only cost 10K deals.  Personally, I like design constraints.  The tighter the envelope, the more creative you have to be.  The rules here were that the big pile of scrap and miscellany had to be tapped and it couldn't look out of place.  This little house is a hodge-podge.  It's 96 years old and has never met an architect or had a posh redo.  It's been a little house in which families were raised negotiating for a single bath and space in a small kitchen.  That's togetherness.  Because of this, I wanted the pond to have the same feel -- a sort of "this was made with materials at hand" kind of thing.  For this project, that meant odd-shaped bricks, broken concrete, worn 2x12s, and roofing tin.

Next was the liner. Plenty of liner. You never want to be short. After all, you might want to build ANOTHER pond, or marsh garden, or even something for your mother.

Fill it up - the true test of level.

Smooth out wrinkles during the fill. Don't cut until you are
absolutely sure things are as you desire. Even then,
better to hide extra liner than trim if you can.

South side gravel wall complete, but will be redone in a few
days. I couldn't stand the lack of levelness of the bricks.
I wanted it to have a casual feel, but not sloppy.

Rain chain plumbing installed. This too would undergo
modification in subsequent weeks.

Installing the basin which will become both a focal point
and function as a biofilter.

Garage corner needs protection from the splash and the
basin needs a backdrop.

Giving the backdrop shape and then using acid to age the tin.

Putting the tin in position.

Testing the lights.

Red lens on basin light, yellow on the others.

Lyle loves pond water.

First few plants installed on a rainy day.

If you put water in the garden, prepare for many visitors.

The initial algae bloom has cleared and Lyle notices the fish
for the first time. 

I'll post more pics as the plants I've ordered come in and either die or take hold.  The pond is in full shade, so planting is tricky. But, like I said, the tighter the constraints, the better the creativity workout.

Using the OsmAnd app to find earthen roads in Nebraska

Background Info
Turquoise = earthen road

In previous posts I mentioned that I have building a downloadable collection of the earthen roads in Nebraska.  If you've not read the previous posts, "earthen roads" refer to those roads classified as minimum maintenance roads (MMRs) and primitive roads. Finding them while riding a bicycle or a motorcycle is often a treat because they tend do be in a condition that tests your riding skills and take you where few other tend to go, which is why they are unsurfaced.  Here in Nebraska, you might find abandoned homesteads, giant washouts, small graveyards, expanses of never-tilled pasture, and a wide array of wildlife. Consequently, when out on my bicycle or moto, I like to find and ride as many of these as possible.  Unfortunately, they often extend only one or two sections at a time and are not linked, rendering the discovery of one somewhat deliciously serendipitous, but at the same time frustrating. 

Fortunately and major thanks to the Nebraska Department of Roads, I am slowly but surely building up a collection of routes that can be downloaded and imported into any number of GPS navigation devices from a Garmin to the multitude of phone-based apps. If you do this, you'll be able to easily  locate these roads.  I will cover using this data to create continuous routes maximizing the use of earthen roads in another post.

A little technological context:
The files:
The .gpx file is compatible with more apps, but the .kml file is Google's format - Keyhole Markup Language and works with Google Earth, both on the desktop/laptop and in the mobile version. Because I find Google Earth to be my preferred tool for managing data related to location, my process often involves "Saving Place" as a .kml file then using GPSBabel to convert the .kml to a .gpx that can be imported to a wider variety of sites and apps.

The Android app I want to introduce to you today is called "OsmAnd" which stands for OpenStreetMap Automated Navigation Directions.

One of the coolest features is its use of vector-based maps from the OpenStreetMap project, which means that the maps can be used offline - no need for a data connection. Between that and the GPS chip in most modern phones, you've got a full-fledged GPS unit that's not going to run up your data bill.  To be fair, most apps of this type offer other ways of caching maps for offline use, but they involve the use of "tiles," which are graphic images that must be downloaded at a variety of magnification/size so that you are able to zoom in and out while in offline mode. To me, that seems an unnecessary use of space if the vector-based maps have the data you need.(More info: vector, tile/raster maps)

Putting OsmAnd to work
1 Download and install the app.  OsmAnd is the free version, OsmAnd+ is the paid version.  There is no difference in functionality and there are no ads in the free version.  The only restriction is that you may have only 10 vector maps downloaded at any one time.  This is not a big deal.  I have the paid version because I use the app all the time and it doesn't code itself. 

Download the Nebraska and World overview map
2 Start OsmAnd > Settings > Manage Map Files
You will see a link "Click here to download or update offline map files".  There is a search at the top of the screen. Type in the names of the maps to locate them quickly. The vector maps are based on OpenStreetMap data and are updated about every two weeks.  Recommend regular updates.

Download the Earthen-Roads-2014-10-20.gpx file.  This link is a share link. In working with these map files, I have found the easiest way to load and export data to be by using cloud storage, specifically Google Drive and Dropbox. So here are the options:
  1.  Use your laptop to download the file to whatever cloud storage you use and which is installed on your mobile. Google Drive and Dropbox both work well.
  2. On your mobile, open the cloud storage app, find the .gpx file, select it and you will be prompted to select an app to open it. Choose OsmAnd.  
(If you are accustomed to connecting your mobile to your desktop/laptop via a usb cable, you can also drag and drop the .gpx file into the folder on your mobile.) 

After selecting OsmAnd to open the file, you will be taken to the map view in OsmAnd and you should see a bunch of small turquoise lines.  These lines are the stretches of road that are classified as "earthen."

 Configure the interface
Preferred settings in bicycle mode.

Although OsmAnd does turn-by-turn directions, that's not how I like to use it. I prefer to set a destination and then have an indicator that let's me know if I am going in the general direction of my destination. It seems to allow a bit more freedom exploration on the way.  These types of apps are incredibly configurable because the people that use them have such varied purposes, so if you don't like something, the app probably does it the way you want, but you have to figure out how to set it. My prefs:
In the lower left of the screen or from one of your menu buttons, you can open the menu. Select

Configure screen
These are the ones I have checked:
Street name
Where am I
GPX recording
Show destination direction
Display position always in center
Show cycle routes

I also like the lines to be shown with more contrast. They are easier to see at a glance.
Under the heading of Map rendering:
select Map style > Touring view

  • Return to the map.  
  • Press near one of the earthen roads. A little bubble will appear with location info, press that and select Set as Destination.
  • Return to your current position by pressing the location icon (circle with blue dot) in the upper right corner of the screen.
  • You'll see that the checkered flag (your destination) has the distance to the spot beside it and that there is a red triangle pointing in its direction.
  • Now set your compass view.  Your options: fixed, north always up, direction of travel, or compass. I prefer north always up.  It seems to help me keep a mental map in my head as I travel around. 
  • If you want to record your track, press the button under the destination flag in the upper right corner. 
Now, go try it out.
While you're out traveling, press in any spot to create a waypoint . There are a few different kinds. If you want the waypoint to be added to the track you're recording, choose "Add GPX waypoint."  If it's a spot you want to return to frequently, consider adding it as a "Favorite" which you can locate under "My Places" in the future.

Where to go from here:
Ok. That seems like a lengthy tutorial to just open a single file. It is, but like I said before, these types of apps are quite powerful and used for diverse purposes, so they have quite a lot of options. Play with it, put questions in the comments, and I'll keep posting about various features and uses.

Where the Gravel Ends

Google Earth screen capture of the earthen roads of Otoe and Cass counties. 
I mentioned the county maps previously in discussion the Stream Crossings project, but this post will discuss them in more detail.  In Nebraska, there are three classes of  "dirt" roads: gravel surfaced, unimproved, and primitive.
Legend excerpt from county maps.
Primitive and Unimproved types are generally referred to as "MMR's" or minimum maintenance roads and are denoted in Nebraska with caution type signage.

Photo from "Where are the Plastic Animals" blog.

This summer I have been studying the county maps and making routes in the following fashion: My process was to take the PDF's of the county maps, use a digital high-lighter, mark the MMR's, then use another colored high-lighter to draw a route which maximized the usage of MMR's. I would then recreate the route in Google Earth to get a digital file that I could use with my mobile's GPS app.

MMR's marked in yellow, route in purple.
The process was effective, but tedious, but because I couldn't afford a copy of MicroStation, a CAD-like application, in which the county maps are built, there wasn't a way for me to digitally extract the data layers I needed. Finally, late one night I noticed the following at the bottom of the map downloads page:

Please let us know how you use the maps and what would be helpful for you.
Although we can't promise anything, we will make every attempt
to reasonably meet your county map needs via this site"

So, I did.  I explained what I was doing and what I needed in the web form and the next day received a phone call from Nebraska Department of Roads (NDOR).  Could I explain in a little more detail?  Of course. Stop me when you've had enough.

A few days later, I received an email.  The attachment was a .kml file, which is Google Earth's file format, containing the "earthen"  roads of Dakota, Dixon, and Cedar counties.  In a few clicks I was able to import this file directly to my mobile.  I was pretty much ecstatic.  With this file type, I didn't even really need to create routes anymore. I could simply load the file, set my ultimate destination, and hten take MMR's as they came into view in my mapping app.  This allows for a more free-form exploration of the countryside.  Since then, I've received a few more counties and each time, I add them to a single Google Earth layer.  This is enormously helpful to me and I cannot express enough thanks to NDOR which has taken on the tedium.  While not needing to use a highlighter or recreate lines, MN at NDOR has graciously cleaned and tidied the files.  If you look at the legend again, note how the MMR roads are dual lines, not a single line.  I think this means that MN is taking the time to go into the file and delete the extra lines for each and every length of MMR.

So, what I am I going to do with this data?  Well, I have this idea of a route around Nebraska that parallels the scenic byways, but maximizes the use of MMR's. I plan to include good places to camp, recommended restaurants and pubs, and other things of interest.  All this information will be available in a few easily downloaded files.  In future posts, I will get into more detail about how to use these files and which apps I am finding most useful. If this is of interest to you and you have routes you like already, or wouldn't mind doing some testing, please do let me know.

If you already know your way around .kml files, then you may enjoy playing with these two:

Using photo geotags to document bicycle infrastructure issues

Much of what is said about the geo tags in photos relates to privacy and concerns how to turn off the feature in mobile-based cameras.  However, judicious use of this tool can leverage the power of mapping and crowd-sourcing to to identify patterns and document issues.
Keeping track of trail deterioration can be challenging, but the ease of taking a photo combined with geotags could simplify the process.

For example, on my commute this morning, I took two photos.  The first to attempt to capture the beauty of the swath of cosmos flowers gracing the Antelope trail in the morning sun, the second to note how the concrete west of the Holdrege pedestrian bridge is sinking and cracking.

If you click on "Photo Details," the photo metadata will be displayed along with the location data. You can see how a large collection, documented by many riders, could help give a much improved understanding of bicycle infrastructure issues.  Additionally, taking pictures where negative car/bike interactions occur could also lend insight to where outreach or infrastructure changes may need to be done.

Nebraska Bridges and Meandering Streams

In August, a friend and I pedaled over to Henry's on South for dinner.  Afterwards, we noticed Iron Tail Gallery had a magnificent photo of a country bridge in the window.  It was the final day of a photo exhibit and we stopped in. The show was Michael Farrell's Stream Crossings.  Accompanying each photo were blocks of text taken from Farrell's essay, "Stream Crossings: Where the Relentless Rationality of an Applied Physical System Intersects with Our Meandering Prairie Watercourses." In this essay, he discusses the impact of overlaying the natural layout and boundaries of the land with the one-mile square grid system that facilitated the parceling out and settling of property.  In particular, Farrell notes how this has impacted the public's ability to view, enjoy, and protect its waterways.

Image: Michael Farrell, Stream Crossings
"If our water is considered to be a resource owned by the public, what of these complex river systems? How can we divorce our watercourses from the life-giving water that runs through them? Isn’t a river, creek, or stream an integral natural system overflowing with all manner of life and complexity—including our own?

Does a river or stream, as a complex living habitat, have a kind of integrity that should be considered to be inherently something other than private property? We know more now, and our attitudes have evolved from what we understood or assumed in the time of Jefferson or Lincoln—or the bully Roosevelt boys—or even Richard Nixon, signer of the Endangered Species Act, for that matter.

If a corporation can now have legal standing to speak out and influence laws or elections, what standing accrues to a river or stream, without whom none of us can live?

And, if so, who among us will be empowered or emboldened enough to dare to speak out or to act on behalf of our essential yet increasingly vulnerable watercourses?"

In reading the essay as I moved through the exhibition, I noticed the background image of the paper.  It was a replica of one of the very county maps I had pored over in making my plans for my first multi-day gravel-road moto tour and an idea was sparked.

I would contact this Farrell fellow and see if I could get the GPS coordinates of the bridges. Then, I would take the moto and go take my own photo.  I have since learned that some call this "geo-picting," and it is akin to geocaching.

Farrell graciously shared a set of coordinates with me and MFD and I packed a picnic lunch and went a-seeking.

At each find, we stopped and explored, discussing this or that about the bridge or the stream area it spanned.
The day sped by and when we finally turned and headed for home, it occurred to me that it might be cool if others could easily download the coordinates, find the same locations, and also take pictures of the same bridges. Moreover, what if everyone's pictures were collected in one place so that one could view a bridge in different light at different times from different angles - a sort of group exploration of a particular subject?  In this case, bridges, property rights, etc., so I've set about figuring out ways something like this could be done without anyone choking on the technology.

For me, barreling down those grid-straight country roads then stopping to contemplate the bridge over the natural meandering stream barrier made the content Farrell's essay more real than it had seemed upon first encounter in the gallery. I find myself thinking about it whenever I see one of these pony truss bridges.

Since then, I've spent a great deal of time identifying and getting the technological processes down, or at least nearly so, (I still need to test iOS apps) and I am putting together some ideas which I'll share at a later date.

Many of Nebraska's bridges are not only out of service, but they are not documented as being out of service on its county maps or downloadable map data.  Frequently, explorations down little traveled roads end in something like this.
