Layer Updates

We have just updated four layers showing Land Cover (Land Cover 2006, Land Cover Change 2001 2006, Land Cover Impervious Surfaces 2006, Land Cover Impervious Surface Change 2001 2006) to IndianaMap. These layers were re-processed by IGS staff from the amended version (October 10, 2014) of the 2006 National Land Cover Database (USGS).  If you are a frequent user of these data, please use the link below to access the Layer Gallery for free downloadable data and metadata, access the REST service URLs, or add it to you next custom map.

  • Land Cover 2006 – Shows fifteen categories of land use in Indiana. This grid is a subset of the 2006 National Land Cover Database (NLCD 2006). The amended version was released on October 10, 2014, and was produced through a cooperative project conducted by the USGS Multi-Resolution Land Characteristics (MRLC) Consortium. The land cover classification was achieved by using a combination of Landsat imagery and ancillary data.

Landcover2006

  • Land Cover Change 2001 2006 – Shows 2001 to 2006 Land Cover Change in Indiana. This grid is a subset of the National Land Cover Database (NLCD 2006) suite of data products. An amended version was released on October 10, 2014, and was produced through a cooperative project conducted by the USGS Multi-Resolution Land Characteristics (MRLC) Consortium. There are 17 categories of land use shown in this data set. The pixel attributes are assigned only to pixels that changed land-cover classification between 2001 and 2006, and the attributes are those of the 2006 land-cover classification. The land cover classification was achieved by using a combination of Landsat imagery and ancillary data.
  • Land Cover Impervious Surfaces 2006 – Shows estimated percentages of impervious surfaces in Indiana. This grid was produced in association with the 2006 National Land Cover Database (NLCD 2006) data set. An amended version was released on October 10, 2014, produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium.
  • Land Cover Impervious Surface Change 2001 2006 – Shows 2001 to 2006 Land Cover Change in Indiana. This grid is a subset of the National Land Cover Database (NLCD 2006) suite of data products. An amended version was released on October 10, 2014, and was produced through a cooperative project conducted by the USGS Multi-Resolution Land Characteristics (MRLC) Consortium. There are 17 categories of land use shown in this data set. The pixel attributes are assigned only to pixels that changed land-cover classification between 2001 and 2006, and the attributes are those of the 2006 land-cover classification. The land cover classification was achieved by using a combination of Landsat imagery and ancillary data.

Layer Additions

We also have just added two new layers showing Land Cover (Land Cover 2011, Land Cover Impervious Surfaces 2011) that were extracted from the 2011 National Land Cover Database (USGS), which was released on October 10, 2014.

  • Land Cover 2011 – Shows fifteen categories of land use in Indiana. This grid is a subset of the 2011 National Land Cover Database (NLCD 2011). The amended version was released on October 10, 2014, and was produced through a cooperative project conducted by the USGS Multi-Resolution Land Characteristics (MRLC) Consortium. The land cover classification was achieved by using a combination of Landsat imagery and ancillary data.
  • Land Cover Impervious Surfaces 2011 – Shows estimated percentages of impervious surfaces in Indiana. This grid was produced in association with the 2011 National Land Cover Database (NLCD 2011) data set. An amended version was released on October 10, 2014, produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium.

(MORE) Layer Updates

We have just updated five layers showing information about the Danville Coal Member in the Geology Folder of the map. The layers show Danville Depth, Elevation, Thickness, Active Mines, and Mined-Out Areas. If you are a frequent user of these data, please use the link below to access the Layer Gallery for free downloadable data and metadata, access the REST service URLs, or add it to you next custom map.

  • Depth to the Danville Coal, 2011 – Shows depth (in feet) to the top of the Danville Coal Member in Indiana. The depth maps were based on coal-test records, mine-map notations, and interpretations of geophysical logs that are included in the files of the Indiana Geological Survey. Different depth ranges were used in the various counties and for different purposes. Since 1980, staff members of the Indiana Geological Survey have also collected and entered coal resource information into the NCRDS database as a cooperative project with the U.S. Geological Survey (USGS). The purpose of the NCRDS Database is to provide a means of rapid retrieval of point-source coal resource information, including coal location, thickness, depth, and other parameters. Based on all available data as of October 2010, a new map of Danville Coal Member depth was created. It is the most current depth map of the Danville Coal Member. Because additional data on coal depth are obtained by the Indiana Geological Survey on an annual basis, interested users may wish to contact the IGS for information on these more up-to-date sources.

  • Elevation of the Danville Coal, 2011 – Shows contours that define elevation ranges (feet above sea level) of the Danville Coal Member. The elevation maps were based on coal-test records, mine-map notations, and interpretations of geophysical logs that are included in the files of the Indiana Geological Survey. Different elevation ranges were utilized in the various counties and for different purposes. Since 1980, staff members of the Indiana Geological Survey have also collected and entered coal resource information into the NCRDS Database as a cooperative project with the U.S. Geological Survey (USGS). The purpose of NCRDS Database is to provide a means of rapid retrieval of point-source coal resource information, including coal location, elevation, depth, and other parameters. Based on all available data as of October 2010, a new map of Danville Coal Member elevation was created. It is the most current elevation map of the Danville Coal Member. Because additional data on coal elevations are obtained by the Indiana Geological Survey on an annual basis, interested users may wish to contact the IGS for information on these more up-to-date sources.
  • Thickness of the Danville Coal, 2011 – Shows contours that define ranges of thicknesses (in feet) of the Danville Coal Member. The thickness maps were based on coal-test records, mine-map notations, and interpretations of geophysical logs that are included in the files of the Indiana Geological Survey. Different thickness ranges were used in the various counties and for different purposes. Since 1980, staff members of the Indiana Geological Survey (IGS) have also collected and entered coal resource information into the NCRDS database as a cooperative project with the U.S. Geological Survey (USGS). The purpose of NCRDS database is to provide a means of rapid retrieval of point-source coal resource information, including coal location, thickness, depth, and other parameters. Based on all available data as of October 2010, a new map of Danville Coal Member thickness was created. It is the most current thickness map of the Danville Coal Member. Because additional data on coal thicknesses are obtained by the Indiana Geological Survey on an annual basis, interested users may wish to contact the Indiana Geological Survey for information on these more up-to-date sources.
  • Active Mines in the Danville Coal, 2010 – Shows the location and extent of active surface and underground coal mines in the coal region of west-central and southwestern Indiana that mine the Danville Coal Member. It is attributed to allow the mine polygons to be differentiated based on mine number, mine name, county name, and the mine owner. These data contain information that is related to two additional GIS data sets produced by the Indiana Geological Survey: 1) COAL_MINE_UNDERGROUND_IN: Underground Coal Mines in Indiana (Indiana Geological Survey, 1:24,000, Polygon Shapefile), 2) COAL_MINE_SURFACE_IN: Surface Coal Mines in Indiana (Indiana Geological Survey, 1:24,000, Polygon Shapefile).
  • Mined-Out Areas of the Danville Coal, 2010 – Shows the location and extent of the mined-out areas in the Danville Coal Member in the coal region of west-central and southwestern Indiana. It includes mine locations from documented surface and underground mines that operated in Indiana since the late 1800s. It contains attributes for each mine location, to be differentiated based on mine number, county name, and mine type (surface or underground). This shapefile contains information that is related to two additional GIS data sets produced by the Indiana Geological Survey: 1) COAL_MINE_UNDERGROUND_IN: Underground Coal Mines in Indiana (Indiana Geological Survey, 1:24,000, Polygon Shapefile), 2) COAL_MINE_SURFACE_IN: Surface Coal Mines in Indiana (Indiana Geological Survey, 1:24,000, Polygon Shapefile).
