Surficial Geology (1:24,000) - Postglacial Deposits
Entry ID: MassGIS_GISDATA.SURFGEO24K_PG_POLY

[ Update this Record ]

Summary
Abstract: The postglacial data layer is part of a comprehensive study to produce a statewide digital map of the surficial geology at a 1:24,000-scale. This compilation of surficial geologic materials defines the areas of exposed bedrock, and the boundaries between glacial till, glacial stratified deposits, and overlying postglacial deposits. The postglacial layer shows areas of swamp deposits, floodplain alluvium, and artificial fill. Swamp polygons may overlie alluvium polygons; artificial fill polygons may overlie areas of swamp or alluvium. This data layer should be used in conjunction with the underlying till bedrock, stratified deposits, and early postglacial data layers. MassGIS stores this layer as SURFGEO24K_PG_POLY.

Purpose: The purpose of this study is to provide fundamental geologic data for the evaluation of natural resources, hazards, and land information within the Commonwealth of Massachusetts. The postglacial deposits data layer is part of a comprehensive effort to produce a statewide digital map of the surficial geology at a 1:24,000-scale. This compilation of surficial geologic materials defines the areas of ... View entire text

Quality ATTRIBUTE ACCURACY REPORT: Attributes have been visually checked by the compilers.

LOGICAL CONSISTENCY REPORT: Polygon features conform to the following topological rules. There are no duplicate polygons. Polygons do not self overlap. Swamp deposits may overlap floodplain alluvium polygons. Artificial fill polygons may overlie swamp or alluvium polygons. No automated procedures or tests were ... View entire text
