Introduction:

The spatial GIS layers contained in this ZIP file were exported from the MCM-LTER Spatial Database in the ESRI Shape File format. For your convenience, Layer Files (.lyr), which are already symbolized, are also included. The spatial layers contained in the MCM-LTER Spatial Database are the most up-to-date and accurate (depending on the date the shapefiles in this ZIP file were last exported, they may be out of date). Other MCM-LTER GIS options and resources can be found at the following URL:

Instructions:

1) Extract the ZIP file into a directory on your hard drive
2) Open ESRI's ArcMap version 9.X or higher
3) Add the layer files in the root directory (files with the .lyr extension). These layers are already symbolized.  Alternatively, you can navigate through the subdirectories and add the .shp files to your map.

Short History:

Most layers in this ZIP file are from the 1977 USGS Quads. These layers were originally created by Mike Prentice's team at UNH as part of the VALMAP project. In 2007, the layers were cleaned up and properly attributed by Chris Gardner (MCM-LTER Information Manager). They were then added to the MCM-LTER Spatial database, exported, symbolized and added to this ZIP file. Other layers such as glacier stake locations, met station locations, camp locations, etc. were created by Chris Gardner.

Note that many layers are encoded with URLs to actual data for that feature on the MCM-LTER website.
