AK DGGS GeMS MM Update 07 Oct 2019 Decided on employing a field named layer with integer values (allows for its use a subtype) of 1 or higher for surficial layers and -1 and less for bedrock layers, 0 for undefined. Phases of Production Documentation Creating symbol_info table Continue to develop Type and Category Domain lists for each feature class Field Order & Select Special Fields distribution_policy draw_policy data_sources_method assoc_feature_id symbol_alt modifier map_unit_assoc & map_unit_obs Web app demo available on our Enterprise Portal https://geoportal.dggs.dnr.alaska.gov/portal/home/
