Service Description: This vector data set contains the rock unit polygons for the 1:24,000-scale statewide surficial geology. This layer was created by merging 1:24,000-scale rock unit polygons from Delaware Geological Survey (DGS) published surficial geologic maps. This surficial geology layer represents the "current thinking" of the DGS and may be different from original geologic interpretations portrayed on the published maps.

Subject: To facilitate the GIS community of Delaware and to release a statewide 1:24,000-scale surficial geologic layer. This layer represents the "current thinking" of the DGS geologic staff of the surficial geologic units. This information is important not only to geologists, but also to hydrologists who wish to understand the distribution of water resources, to engineers who need bedrock information during construction of roads and buildings, to government officials and agencies who are planning for residential and commercial growth, and to citizens who are curious about the bedrock under their homes. Formal names are assigned to all rock units according to the guidelines of the 1983 North American Stratigraphic Code (NACSN, 1983).
