Coordinate Systems

Point, line, and polygon data are expressed as vertices in GIS files (shapefiles, gdb files or point DBF files), but there are many types of units for these coordinates. Example coordinate systems include:

§        geographic (latitude and longitude, spherical coordinates on the globe)

§        planar (projection of spherical coordinates to a plane)

o       UTM

o       Albers equal area

o       Lambert conformal conic

 

SpaceStat cannot project imported data from geographic coordinates or convert (reproject) data from different planar projections. You must import all of your datasets in the same coordinate system to have them overlay properly in the map and for spatial analyses.  If your imported data includes a *.prj file, SpaceStat will show the coordinate system of the data in the data source properties.
