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). |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>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.</SPAN></P></DIV></DIV></DIV> |

<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. These data should not be used for navigational, engineering, legal, or any other site-specific use. Nothing contained herein shall be deemed an expressed or implied waiver of the sovereign immunity of the University of Delaware and the State of Delaware or their duly authorized representatives, agents, or employees.</SPAN></P></DIV></DIV></DIV> |
