Problem: Reprojected geographic data greater than +180 or less than -180 degrees does not display in ArcMap
A dataset that has longitude values less than -180 or greater than +180 does not display after being reprojected.
Geographic data is categorized by its longitude range into one of three types:
· -360 to 0
· -180 to +180
· 0 to +360
If the data falls between +/-180 and +/-190, the data is categorized incorrecty as +/-180.
Solution or Workaround
Do one of the following:
- Add data that has a longitude value greater than 190 degrees.
- Install the newer version of ArcMap 8.1.2.
