Emmitsburg Trail Map

Wednesday, November 13th, 2013

I’m glad the MORE board of directors enjoyed their ride on the Emmitsburg Trail.  I spent most of my summer out their as a subcontractor for Austin and Trails Conservancy.  A lot of sweat went in to that singletrack.

Multiple Sources, Multiple Policies

Monday, October 14th, 2013

The license agreement on government data sets varies widely.  In the best case they are public domain. In the worst case they are not released.  Sometimes the use is heavily restricted.  The good news is that there is rarely a sole source of data for a given project.

This project is a park in Annapolis. The town will provide data but the license agreement is onerous.  A map cannot be created and distributed to persons outside the project. But Annapolis lies within Anne Arundel County.  The county data sets are public domain so I can use them as I see fit.  Other options are open source, state and federal government, and civic organizations.

The moral is don’t stop at one source. You might find better terms or better data in other holdings.  It’s a great way to quality check too.  One hours research led me to all of this for free.


Annapolis Rocks

Tuesday, April 2nd, 2013

Low miles and moderate elevation make this a popular weekend getaway for the Baltimore and DC crowd.  The rock outcrops offer a nice view and technical routes from 5.4 to 5.10+.  Camping is no longer permitted at the cliff top but several sites are available further back.  The trail, camp, and composting toilet are maintained by the Potomac Appalachian Trail Club.


Overnights in the Everglades

Tuesday, March 26th, 2013

I’ve never been to the Everglades, but I have been on the water and I’ve been to a great many national parks.  I see a few variables that could throw my trip.  Windy days and the waves they create could keep me away from the coastal waters.  Interior rivers and creeks could be too low to traverse.  Lastly, I might not be able to get a permit for the camp sites I want.

So what’s a cartographer to do?  Plan several itineraries and make maps of course.  This map series uses NOAA Raster Charts as a base.  I overlayed the planned route, camp sites, and a 1k UTM grid for easier navigation.  Finally I exported the map as a PFD.  If you have the Terrago plugin for Acrobat, it will display the coordinates of your mouse in Lat/Lon and MGRS.

The routes and text for these two trips are courtesy of http://cmierphotoandfitness.net.  I just placed them on the map.

Between the storms, alligators, and mosquitoes I figure I have an 80% chance of surviving this trip.
