Quality The reliability shapefile was generated from the file of slope corrected orthometric heights (refer to metadata record GRI_ORT_SLC_FIN). All points in the file were used. An area was generated around each polygon using the Thiessen command in Arc/Info. This creates polygon boundaries that fall midway between adjacent points. Polygons surrounding invalid points were merged and the polygons around valid points were likewise merged (Arc/Info Dissolve command was used). This produced a shapefile of areas containing valid points and invalid points. The number of points inside invalid areas was also attached to the invalid polygons (Count field).
Access Constraints Available unprojected or in a Polar Stereographic projection with true scale at 71 degrees S.
ArcView shapefiles are available on the web (refer to the url below).
