The other day, while sorting through long-forgotten computer directories I found an old APA land classification/development plan map from 2001 and thought it would be interesting to compare it to a more recent 2011 version. I uploaded the 2001 map to our Adirondack Regional Geographic Information System (ARGIS) and made a quick video tutorial showing how to easily compare the two:

  • Visit the Adirondack Regional Geographic Information System (ARGIS).
  • Turn on the historic “2001 Land Use/Development Plan Map” at the bottom of the layer list.
  • Turn on the recent “2011 Land Use/Development Plan Map (APA)” under the “Administrative Boundaries” heading.
  • Right-click on the 2011 map layer in the Table of Contents, and select “Properties & Display Options”.
  • Use the “Opacity” slider to turn the 2011 layer on and off, revealing the 2001 layer underneath it.

DEC Lean-to layer


A DEC Lean-to layer has been added to ARGIS. The DEC is in the middle of a big

push to update their assets layer in the Adirondack Park, so check back often
for the latest. If you find omissions or incorrect locations, please let us
know. We plan on adding trail parking and campsites in the next couple months.

John Barge at the Adirondack Park Agency has created a layer that overlays historic bird’s eye maps for several communities in the Adirondack Park onto the modern virtual landscape of Google Earth.  Here’s a tutorial:

We have added basic print map functionality to ARGIS– look for the printer icon on the toolbar.

Newly updated DEC trails layer

The newly updated DEC trails layer for the Adirondacks is now available for viewing and download in a number of formats (shapefile, kml, kmz, wms) via the ARGIS data portal. This layer has been updated by APRGIS in conjunction with DEC unit managers and represents the best digital trails data available yet for public lands within the Adirondack Blueline. As part of the editing process, we created a spatial “network” by ensuring that all trail segments (“links”) were snapped together at trail intersections (“nodes”) and that trails were snapped to the NY Streets layer at trailheads or parking areas. When joined, the DEC Trails and NY Streets layers create a unified transportation network for the park that can be used to locate trailheads, monitor recreational use or even produce seamless driving and hiking directions that guide you from your doorstep to a back country lean-to or mountain vista.
