Plotting geometries that cross the international date line

Spectrum Spatial Analyst can handle rendering and querying of data which goes beyond the international date line. For example, where the co-ordinates of the data exceed either +180 degrees in the east or -180 degrees in the west (or the equivalent in meters for other world projections).

This applies primarily to data in Russia and Alaska. Data from Russia sometimes has co-ordinates in the range of +180 to +192 degrees (rather than -180 to -168), since this shows the country as a single polygon in Precisely MapInfo Pro application. The same is true for some Alaska data where the islands off the west coast go beyond the date line to -187 degree.

Spectrum Spatial Analyst enables you to render eastern part of Russia or western islands of Alaska seamlessly. You can also perform query on the data using point or annotation tools.
