Cross-checking data and field verification

GIS translation of the Model data can be compared with other existing spatial information, like maps produced from satellite-interpreted imagery. Inconsistencies between data sets need to be verified.

Key informants discussing information displayed on a relief model

This should be done by reconvening around the P3-D Models with a sufficient number of informants and through community-based on-field investigation. Philippine experience has shown that peoples' "pooled knowledge", supplemented by conventional spatial information (contours) is not only accurate but more detailed and more current than information maintained in official circles
