What else to add?

Met with Drew and Matt today to look over the map:
What else needs to be added to the initial maps?
Mtns?

Additional Data:
Digitizing Maps
Biophysical Map - Maine Forest Service
Bangor, Augusta, Portland, Maybe LA and Presque Isle

Georeferencing:
a. Turn image into JPEG (copy from word into photoshop)
b. Add data
c. Open tool bar - georeferencing
d. Fit to display (click once)
e. Make sure the right layer is showing in options
f. 'Add Control Points' (little green and red x's)
g. Update Display (to lock and make sure the changes are made - but don't hit fit to display again)
h. Update Georeferencing



Create New Layer in Catalog - MaineIceSheet
Add Data to the Map - start editing out different ice sheet layers
1. make first polygon
2. auto-complete successive polygons
3. doughnut shapes (AR county) - different step go to help to figure out
4. smooth Maine boundary to clip the ice sheet polygons

For Friday:
Use either the pencil or curve option to select out each of the polygons -
Only select the MaineSmooth layer (but still have the editor on the MaineIceSheet layer) -
Go into the options and clip the layer which will bring together each of the new polygons to the MaineSmooth layer.
Use the Cut Polygon Features option to select out the other layers
(Add numbers 0,1,2, etc. in the attribute table to create the gray scale)
