The New Mexico Bureau of Geology and Mineral Resources (NMBGMR) has created this GeMS compliant geodatabase or as near as we can get from our understanding and needs. The only additional or deviations from GeMS is the inclusion of the FGDC_Lookup data table. This is used to provide consistent descriptions of the symbols used in the database and their definition. In the DMU the "symbol" field is used as a complete legend description of each map unit and heading, and as such is is a combination of the HierarchKey, ParagraphStyle, MapUnit, FullName, and Description fields so that the legend can be made in the layout with all of this pertinent information sorted as the author intends.
