Blue Habitat Guide (PDF, 12 MB) ( not a GIS resource, but... )

Michigan Georef .prj file

The parameters for MI GeoRef are included with ArcGIS and may be found under

Coordinate Systems : Projected Coordinate Systems : State Systems: NAD 1983 Michigan GeoRef (Meters).prj  (ArcGIS 9.2 and later)

Coordinate Systems : Projected Coordinate Systems : National Grids: NAD 1983 Michigan GeoRef (Meters).prj  (ArcGIS Pre-9.2)

More information on Michigan-specific projected coordinate systems is available from the Michigan DNR
or from Dave Lusch at MSU

Add X,Y data to ArcMap directly from Excel (PDF) (for ArcGIS 8)

• You can convert upper case or lower case text in an attribute table to "proper case"- an upper case first letter and lower case remainder - by using the following expression in the Field Calculator: StrConv([Existing Field], vbProperCase)
Be sure to replace [Existing Field] with the field that contains the text you want altered, and apply the expression to a new, empty text field. An ESRI help doc on this command is here

 

Add X,Y coordinates to an attribute table in ArcMap (PDF) 

               X-coordinate field calculator expression for the above how-to   (right-click and save file to your computer if it opens in your web browser)

               Y-coordinate field calculator expression  for the above how-to  (right-click and save file to your computer if it opens in your web browser)

 Update: adding X and Y fields is even easier with ArcGIS 9.x. Use the ArcToolbox tool found under ArcToolbox > Data Management Tools > Features > Add XY Coordinates. You can also manually create the empty fields and use calculate geometry, X coordinate of point and Y coordinate of point...
