Aquifer Recharge Rates (Near surface) - Shows estimated groundwater recharge rates to shallow aquifers in Indiana, with units of inches per year. This raster layer (100-m TIFF) was developed by applying a statistical model to a suite of natural-resource variables. The groundwater recharge data used in the multiple regression analysis were derived from calculations of groundwater baseflow and surface-water runoff for 279 streams in Indiana. Estimates of groundwater base flow were determined using hydrograph separation analysis (Institute of Hydrology, 1980) and were converted to recharge by using estimates of runoff following Wolock (2003). The average annual rate of groundwater recharge (in/year) was used as the dependent variable in a multiple regression analysis using ordinary least squares with several landscape and morphometric independent variables representing geologic, terrain, climate, and hydrogeologic characteristics. These data (along with the associated data layer named Aquifer_Sensitivity_Near_Surface_IN.TIF) were created to support decision making in Indiana where knowledge of groundwater recharge rates and sensitivity to aquifer contamination is desired.

Aquifer Sensitivity (Near surface) – Shows ranked categories of aquifer sensitivity in shallow aquifers in Indiana, and is based on estimates of diffuse groundwater recharge rates. The hypothesis is that near-surface contaminants are more likely to migrate downward in areas of increased groundwater recharge. To achieve the aquifer sensitivity ranking, the groundwater recharge rates (see Aquifer_Recharge_Near_Surface_IN.TIF) were classified by standard deviation, and the classifications were then compared to databases of contaminants in groundwater to validate the classification. These data (along with the associated data layer named Aquifer_Recharge_Near_Surface_IN.TIF) were created to support decision making in Indiana where knowledge of groundwater recharge rates and sensitivity to aquifer contamination is desired.

Attributes include station ID's (IEM and FAA), station name, latitude (decimal degrees), longitude (decimal degrees), elevation (meters above sea level), calendar date when the site was initiated, the type of ASOS station (FAA), as well as website URLS to station-specific information for both IEM and the FAA.

The following is excerpted from website documentation for the ASOS network from the IEM:

"ASOS Network - The Automated Surface Observing System (ASOS) is considered to be the flagship automated observing network. Located at airports, the ASOS stations provide essential observations for the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the Department of Defense (DOD). The primary function of the ASOS stations are to take minute-by-minute observations and generate basic weather reports.[1] Observations from the ASOS network are nationally monitored for quality 24 hours per day. Depending on the trouble, maintenance can be performed on the same day."

Weather Stations in Indiana, 2008 (1:24,000) - This is a collection of active weather stations in Indiana that are part of the National Weather Services Cooperative Station Network. The data in this point layer came from the National Climatic Data Center (NCDC) inventories of cooperative weather stations and automated surface observation stations. Attributes include station names, types, and identification numbers, as well as the climate division of the station.

Classified Drainage Flowlines, 20190426 (1:2,400) - Shows classified drainage flowlines as streams, rivers, canals, ditches, artificial paths, connectors and pipelines for all watersheds in Indiana. This layer is derived from the local-resolution National Hydrography Dataset (NHD), and provides currently available data as of April 26, 2019. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. Also, high-resolution NHD, generally developed at 1:24,000 to 1:12,000 scale, adds detail to the original 1:100,000-scale NHD. The local resolution NHD is developed at 1:2,400 scale, and adds even more detail to the NHD.

The following is excerpted from metadata provided by the IDNR: "In order to meet the USGS NHD data model for flowlines, all new flowlines resulting from the Indiana NHD local resolution upgrade project that could not be categorized (artificial path, canal/ditch, coastline, connector, pipeline, stream/river perennial, stream/river intermittent, or underground conduit) were given an FTYPE of Stream/River and an FCODE of Stream/River (46000). Water may or may not be present outside of rain events and may or may not exhibit channelization typically associated with streams. Those features are considered to be 'Unclassified Flowlines'. Records from the reprojected NHDFlowline feature class where FCODE = 46000 were extracted out of this dataset. All records from the source NHDFlowlines where FCODE <> 46000 can be found in this 'Classified Flowline' dataset."

This dataset is complete and includes data for all of the following thirty-eight HUC08 subbasins in Indiana: Auglaize (0410007), Blue-Sinking (05140104), Chicago (07120003), Driftwood (05120204), Eel (05120104), Eel (05120203), Flatrock-Haw (05120205), Highland-Pigeon (05140202), Iroquois (07120002), Kankakee (07120001) Little Calumet-Galien (04040001), Lower East Fork White (05120208), Lower Great Miami (05080002), Lower Ohio-Little Pigeon (05140201), Lower Wabash (05120113), Lower White (05120202), Middle Wabash-Busseron (05120111), Middle Wabash-Deer (05120105), Middle Wabash-Little Vermilion (05120108), Middle Ohio-Laughery (05090203), Mississinewa (05120103), Muscatatuck (05120207), Patoka (05120209), Salamonie (05120102), Silver-Little Kentucky (05140101), St. Joseph (04050001), St. Joseph-Maumee (04100003), St. Mary’s (04100004), Sugar (05120110), Tippecanoe (05120106), Upper East Fork White (05120206), Upper Great Miami (05080001), Upper Maumee (04100005), Upper Wabash (05120101), Upper White (05120201), Vermilion (05120109), Whitewater (05080003), Wildcat (05120107).

Lake Bathymetry, 20190417 (IDNR) - Shows bathymetric contours for 164 lakes in Indiana, depicting the depths of the water from the shoreline of each lake as elevation of zero. Contour intervals are 5 feet for most lakes, 2 feet for some. Lakes were surveyed using Biosonics DTX Echosounder surface unit and 200 kHz and 420 kHz transducers. The contour values for some lakes were adjusted to coincide with the legal gauge level of the lake. Bathymetric contours are available for the following 164 lakes in Indiana:

Adams Lake, Appleman Lake, Atwood Lake, Banning Lake, Bass Lake, Bear Lake, Big Lake, Big Long Lake, Blackcat Lake, Bluegrass Lake, Brokesha Lake, Cass Lake, Cedar Lake, Clear Lake, Cree Lake, Crooked Lake, Dale Lake, Dewart Lake, Duck Lake, Emma Lake, Evertt Lake, Flint Lake, Gage Lake, Gilbert Lake, Graveyard Lake, Green Lake, Griffy Lake, Hackenberg Lake, Heaton Lake, Henry Lake, Hill Lake, Hindman Lake, Hudson Lake, Huntingburg Lake, Indian Lake, Jones Lake, Koontz Lake, Kuhn Lake, Lake of the Woods, Latta Lake, Lime Lake, Lindsey Lake, Little Barbee Lake, Little Otter Lake, Little Pike Lake, Little Turkey Lake, Loomis Lake, Loon Lake, McClures Lake, Meserve Lake, Messick Lake, Meteer Lake, Mud Lake, Nauvoo Lake, North Little Lake, Nyona Lake, Otter Lake, Pike Lake, Pleasant Lake, Pretty Lake, Riddles Lake, Rider Pond, Robinson Lake, Round Lake, Shipshewana Lake, Silver Lake, Simonton Lake, South Mud Lake, Starve Hollow Lake, Steinbarger Lake, Stone Lake, Tamarack Lake, Taylor Lake, Thomas Lake, Upper Long Lake, Waldron Lake, Wall Lake, Waubee Lake, Waveland Lake, West Boggs Lake, West Lake, West Otter Lake, Westler Lake, Witmer Lake, and Yellowwod Lake.

Stream Mileage (IDNR), 20160928 (1:24,000) - Shows stream milage in tenths of a mile (with exceptions). Stream mileage maps for streams in Indiana were originally developed by the U. S. Army Corps of Engineers (Louisville, Detroit and Chicago districts) and the Indiana Department of Natural Resources, Division of Water, from 1965 – 1973. These maps depict stream mileages in tenths of a mile (with exceptions) mapped on USGS 7.5-minute quadrangle maps, at a scale of 1:24000. Methodology for determining stream mileage largely follows the document “River Mileage Measurement”, Water Resources Council, 1968. Points representing each tenth of a mile were captured by DNR staff using georectified copies of the original source documents. These points are attributed with the stream name as shown on the original documents, and the basin, from the Division of Water standard basin schema. This dataset was developed in 2016.Updated hydrographic dataset sources (namely the USGS National Hydrography Dataset) are captured to a much finer resolution than was possible when this data was originally compiled. Additionally, rivers and streams are dynamic, eroding and depositing material and changing course over time, sometimes significantly. Limitations of this dataset compared to other derivations of stream mileage should be recognized. Stream mileage for the Ohio River were taken from the USGS 7 ½ minute quadrangle maps, and are shown at 1 mile increments. Mileage for the Ohio River is historically taken as miles from Pittsburgh (the confluence of the Allegheny and Monongahela Rivers). Discrepancies in the original maps include: Missing mileage data for miles 569-579 for the Ohio River in the Bethlehem quad, an extra 1/10 of a mile between miles 66.5 and 67 for Sugar Creek in Basin 19, an extra 1/10 of a mile between miles 17.5 and 18 for Middle Fork Blue River in Basin 27, an extra 1/10 of a mile between miles 17.5 and 18 for Little Calumet River in Basin 1.

Water-Well Locations in Indiana, 20190613 - Shows the locations of 414,953 water wells in Indiana that are registerd by the Indiana Department of Natural Resources, Division of Water, as of June 13, 2019. Attributes include identification numbers, URL links to water reports for each well, and information about well capacity if measured. Attributes include the location type (located or estimated), depth of the well, pump rate (gallons per minute), static water level (feet below land surface), and the use of the well. One field contains a link to the full detailed well record. Wells with estimated locations should not be used in hydrologic analyses in which location is a factor; wells with detailed locations represent site-specific characteristics, and those characteristics should not be extrapolated to areas beyond the individual well.

The following is excerpted from metadata documentation provided by IDNR:

"The Division of Water Ground Water Database has approximately 415,000 water well records, and of those, approximately 149,550 have been field located and have known x, y (UTM) coordinates, and approximately 14,800 were located by address. The locations of the remaining records are based on the most precise of county, or Township, Range, Section, quarter sections (TRS) locations available from office locating, which is effectively the centroid of the smallest known section or quarter sections; thus, increasing the amount of data available for display and analysis in a GIS format. This dataset and associated table has selected fields from the main digital water well database that are typically needed for most research. Updated June 13, 2019."

Wetlands of Indiana from the National Wetland Inventory (NWI, 2014) - Shows the extent, approximate location, and type of wetlands and deepwater habitats in Indiana, as provided by the National Wetland Inventory (NWI) of the U.S. Fish and Wildlife Service (USFWS). These data delineate the areal extent of wetlands and surface waters as defined by Cowardin et al. (1979). Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and near shore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. By policy, the Service also excludes certain types of "farmed wetlands" as may be defined by the Food Security Act or that do not coincide with the Cowardin et al. definition. Contact the Service's Regional Wetland Coordinator for additional information on what types of farmed wetlands are included on wetland maps. The download file and map service both include the Wetlands Project Metadata layer, which contains project-specific wetlands mapping procedures and information on dates, map scales, and emulsion of imagery used to map the wetlands within specific project boundaries. Digital wetlands data are intended for use with base maps and digital aerial photography at a scale of 1:12,000 or smaller. Due to the scale, the primary intended use is for regional and watershed data display and analysis, rather than specific project data analysis. The map products were neither designed nor intended to represent legal or regulatory products. Questions or comments regarding the interpretation or classification of wetlands or deepwater habitats can be addressed by visiting https://www.fws.gov/wetlands/FAQs.html.

Historic Wetlands of Indiana from the National Wetland Inventory (NWI, 2014) - Shows the extent, approximate location, and type of historic wetland habitats in Indiana. The U.S. Fish and Wildlife Service (Service) is the principal Federal agency that provides information to the public on the extent and status of the Nation's wetlands and provides stewardship for the wetlands data that comprise the Wetlands Layer of the National Spatial Data Infrastructure. In the formulation of this data layer, historic wetlands are defined as areas where there is evidence that a wetland once existed. This evidence can be from historical map information inventories of past wetland extent or other information collected that relate directly to data on wetland filling, drainage or other modifications. Historic wetlands have been identified using several different techniques depending on the availability and type of information used to locate these areas and user needs. For example, historical maps often provide information about past wetland extent or location and can be useful tools to identify historic wetlands. Historic wetlands have been identified as polygonal data. No linear features have been included. Historic wetland polygons are not classified as wetlands and have no wetland labels or attribution. Since these features no longer exist, boundary delineations are considered approximations based on topography, previously mapped information or indications of historic water levels.

The following is excerpted from Microsoft's GitHub "USBuildingFootprints" Web page:

"Our metrics show that in the vast majority of cases the quality is at least as good as data hand digitized buildings in OpenStreetMap. It is not perfect, particularly in dense urban areas but it is still awesome. The vintage of the footprints depends on the vintage of the underlying imagery. Because Bing Imagery is a composite of multiple sources it is difficult to know the exact dates for individual pieces of data. While our metrics show that this data meets or exceeds the quality of hand drawn building footprints, the data does vary in quality from place to place, between rural and urban, mountains and plains, and so on. Inspect quality locally and discuss an import plan with the community."
