Getting the data

Concepts:
   layer files for DEP users
   ArcSDE layers for state agencies
   MEGIS data catalog for everybody else

DEP users
Like most other GIS data, you can find these layers in the folder workspace\data_layers, under 'landuse_landcover'.  Just add any of them to ArcMap from this location.

ArcSDE layers for State of Maine employees
Anybody connected to the State of Maine WAN can connect to the MEGIS ArcSDE server and get the same layers as ArcSDE rasters, these are the layer names:

Contact the Maine Office of GIS to get access to the SDE server if you don't already have access.

Everybody else
Anybody outside the State WAN can use one of three methods to access the data, you can either download the data directly from http://megis.maine.gov/catalog, use the ArcIMS orthomap service http://megisims.state.me.us/website/orthomap, or contact the Maine Office of GIS for a DVD-R with all the data.  The ArcIMS service can either be used in the viewer link provided above, or can be connected directly to ArcMap.  The IMS service only provides the MELCD 2004 landcover data.

This class is designed for DEP users and will thus refer to the layer files above, but the tools shown here will apply to all 3 groups of users.
