<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This GIS vector data layer contains the lithologic unit polygons for the surficial geology in Delaware. This layer was created by combining vector data from the Delaware Geological Survey (DGS) Geologic Map Series. This data layer represents the "current thinking" of the DGS and may be different in certain areas than the geologic interpretations portrayed on the original published maps, mainly due to edge matching polygons from different time periods.</SPAN></P></DIV></DIV></DIV>
This layer represents the "current thinking" of the Delaware Geological Survey (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 lithology under their homes.

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The Delaware Geological Survey (DGS) is constantly gathering data from multiple sources, interpreting the data, and reflecting its interpretations on maps. Geology information included in this 1:24,000 scale surficial geology layer are the result of DGS's interpretations of multiple data sources. Reasonable efforts have been made by DGS to verify that this layer and the digital data provided herein accurately interpret the current understanding of the surficial geology of the state; however, this means that this layer may differ from previously DGS published surficial geologic maps. This digital polygon layer may also contain omissions and errors in scale, resolution, rectification, positional accuracy, development methodology, interpretations of source data, and other circumstances. This geologic information is also date specific and as additional data become available and as verification of source data continues, this geologic information contained herein may be reinterpreted and updated by DGS without notification.
