7.B. Vertical Accuracy

The absolute vertical accuracy of GLOBE varies by location according to the source data. Generally, areas derived from raster source data have higher accuracy than those derived from vector source data. However, some data that were delivered to GLOBE (or to the MISR or GTOPO30 DEMs) as rasters came from cartographic sources, thus complicating assessment of their accuracy.
