Usage Note 40034: Deprojected longitude and latitude values might not line up with map longitude and latitude coordinates
When combining longitude and latitude values with a SAS/GRAPH map data set, the values might not be placed as expected on the map.
The problem can occur when the map data set contains deprojected longitude and latitude values. The deprojected values are approximations of the original longitude and latitude values that are calculated using an algorithm to convert projected values to their original values before projection.
To determine if the SAS/GRAPH map data set contains deprojected longitude and latitude values, you can run the following statements, changing the name of the map data set as needed:
proc contents data=maps.peru;
run;
In some cases, the SAS/GRAPH map data set has been updated to replace the deprojected longitude and latitude values. To determine if there has been an update to a particular SAS/GRAPH map data set, you can check for map updates at the
Maps Online web site.
