November 6, 2014 – Layer Updates

4 Local County-Based Framework Layers Updated – the four county data sharing layers that provide county-based framework data have been updated:

The layers were compiled from data maintained by various county agencies in Indiana, as part of the IndianaMap County Data Sharing Initiative between Indiana Geographic Information Council (IGIC), Indiana Office of Technology (IOT), Indiana Geographic Information Office (GIO), Indiana Department of Homeland Security (IDHS), Indiana Geological Survey (IGS), and participating Indiana counties. NOTE: These layers are part of the EIGHTEENTH set of data harvested through the State’s ongoing County data sharing initiative program on October 14, 2014. These layers are provided “as-is” and are not guaranteed for completeness, accuracy, or content, and should not be used for any official or business purpose. Be sure to read the full metadata for each layer.

The IndianaMap Map Gallery has a customized map named “Data Sharing Initiative Layers” that can launch the map with one click and loads all four of these updated layers. Click to begin examining these data in your area of interest.


October 14, 2014 – Layer Updates

Two new layers have been added to the Imagery Folder showing “1998-1999 DOQQs (USGS)” and “2013 Orthophotography” (covers the western-portion of Indiana).

1998-1999 DOQQs (USGS) – Shows the 1998-1999 Digital Orthophoto Quarter Quadrangle (DOQQ) imagery of Indiana, produced by the United States Geological Survey (USGS). These data are grayscale, with a 1-meter ground resolution. The DOQQ combines the image characteristics of the original photograph with the georeferenced qualities of a map. Each DOQQ covers an area measuring 3.75-minutes longitude by 3.75-minutes latitude, approximately 5 miles on each side, or a quarter of the standard size of a USGS 7.5-minute quadrangle map.

2013 Orthophotography – Shows the orthophotography for 30 counties in western Indiana, collected during leaf-off conditions in 2013. The imagery is natural-color high-resolution (3-band) orthophotography, with an established standard resolution of 1-foot. Six counties chose to upgrade to imagery with 6-inch resolution (Dubois, Lake, LaPorte, Marion, Porter, and Spencer). Additionally, the cities of Bicknell and Vincennes purchased 6-inch imagery, and the city of Huntington and Purdue University obtained 3-inch imagery. From 2011 to 2013, the State of Indiana undertook a 3-year program to acquire orthophotography (RGBI) and LiDAR/elevation data for the entire state of Indiana. The program divided the state into three acquisition areas: center-portion – 28 counties (2011), eastern-portion – 34 counties (2012), and western-portion – 30 counties (2013).

We have updated the Geology layer showing Indiana’s industrial minerals producers in 2001 with an updated layer.

Active Industrial Mineral Operations (2010) –Shows the locations of industrial mineral operations that were active in 2010 in Indiana. These operations extracted and (or) produced the following commodities: cement, clay and shale, crushed stone, dimension limestone, dimension sandstone, gypsum, lime, peat, slag, and sand and gravel. Source data were compiled by the Indiana Geological Survey as a publication named Directory of Industrial Mineral Producers in Indiana, 2010.

September 18, 2014 – Layer Updates

We have just updated four layers to the IndianaMap. If you are a frequent user of these data, please use the links below to access the Layer Gallery to download data and metadata for each of the updates.

Three layers of IndianaMap Local-Resolution Hydrology layers have been updated:

These three layers represent the latest release by the Indiana Department of Natural Resources (IDNR) of the Local-Resolution National Hydrography Dataset (NHD), and are current as of September 5, 2014.

NHD data for Indiana was originally developed by the USGS at two scales 1:100,000-scale and High-Resolution 1:24,000 scale.  This new Local-Resolution NHD is developed at 1:2,400 scale, and adds even more detail to the NHD.

Production of this new Local-Resolution NHD dataset is in-progress and currently includes data for the following eighteen HUC08 sub-basins in Indiana: 04100007 (Auglaize), 05140104 (Blue-Sinking), 05120204 (Driftwood), 05120203 (Eel), 05120104 (Upper Eel), 05120205 (Flatrock-Haw), 0712002 (Iroquois), 05120208 (Lower East Fork White), 05120113 (Lower Wabash), 05120111 (Middle Wabash-Busseron), 05120105 (Middle Wabash-Deer), 05120207 (Muscatatuck), 04100004 (St. Marys), 05120110 (Sugar), 05120206 (Upper East Fork White), 04100005 (Upper Maumee), 05120201 (Upper White), and 05120107 (Wildcat).

Remediation Institutional Control Sites – This existing layer from the Indiana Department of Environmental Management has been updated and is current as of September 16, 2014. When any amount of contamination above a residential closure level is left on a property, a legal measure called an Institutional Control (IC) may be needed. An IC protects human health and the environment by restricting property activity, use, or access. Institutional Control (IC) polygons were created from recorded Environmental Restrictive Covenants (ERCs) and other Institutional Controls (ICs) mandated by IDEM.


 September 3, 2014 – Layer Updates

We have just added one new layer and updated another layer to the IndianaMap. If you are a frequent user of these data, please use the links below to access the Layer Gallery to download data and metadata for each of the updates.

PLSS CadNSDI BLM – This new layer has been added to the map with information that is current as of June 11, 2014. It shows the Public Land Survey System (PLSS) of the Cadastral National Spatial Data Infrastructure for Indiana, and was supplied by the Bureau of Land Management. The Cadastral National Spatial Data Infrastructure (CadNSDI) Survey Program of the BLM provides the official boundary surveys of all federal-interest lands in the United States, which is over 700 million acres, nationwide. The PLSS is the foundation for many survey-based geographic information systems.

Electric Service Territories – This existing layer has been updated with information that was supplied by personnel of the Indiana Utility Regulatory Commission (IURC) on August 6, 2014. It shows the electric service territories served by the regulated electric service providers in the state of Indiana.
