It is possible to utilize the vast amount of geographic data available from the Indiana Spatial Data Portal and IndianaMap while working in AutoCAD Civil 3d. A FREE software add on in from ESRI is available to help the autodesk engine connect to the vast amount of useful information these web sites make available. (http://www.esri.com/software/arcgis/arcgis-for-autocad)

From highway routes to watersheds, from voting districts to multiple years of aerial photography the information is connected by server inside your cad files to be used as you need them. No need to download the myriad of information and store it on your computer. IndianaMap has it ready for you 24 hours a day and it’s updated consistently to give you the best available information.


At the LaPorte County Surveyor's Office we have just begun using this invaluable data services and its potential seems limitless in saving time and bringing information together. These data services give us the ability to bring in information quickly and efficiently to give us the chance to work on the details and leave the base data to the IndianaMap and the Indiana Spatial Data Portal.
Warren County Commissioners signed an agreement last week to share four key GIS data layers with the Indiana Geographic Information Office. The ongoing Data Sharing Initiative began in 2008 when commissioners from all 92 Indiana Counties were invited to augment the value of their GIS data by allowing the Indiana Geographic Information Office to access and integrate land parcels, road centerlines, point addresses, and local administrative boundaries in order to create and distribute statewide versions of these critical data layers.

Jim Sparks, Indiana Geographic Information Officer offers his congratulations to the citizens of Warren County and the state of Indiana who will soon receive additional benefit from their data investment: “Thank you, Warren County Commissioners! With this agreement, Warren County will fill the void that currently exists for their county when site selectors, consultants, contractors, educators, and others look for these four state wide data layers on the IndianaMap (www.indianamap.org).”

Statewide geographic information is especially important to economic development because site selectors are increasingly interested in understanding data about regions rather than a specific city or county. These data are also critical in times of crisis, as demonstrated in Clark County after the 2012 tornado ripped through that county: “We wanted to be able to quickly produce field maps and other geospatial data products to help our community, the Indiana Department of Homeland Security, and FEMA understand and best respond to the rapidly changing situation in our county,” said Vicky Kent Haire, Clark County Assessor. “Having accurate land parcels, road centerlines, and other data already integrated in statewide data layers before the event saved a lot of time in a situation in which every minute was critical.”

Only Boone and Marshall Counties have yet to share their public information with the IndianaMap.
We are happy to report that a new release of Indiana's OpenTopography Server is now available. OpenTopography Server provides FAST and FREE access to download custom LiDAR and DEM data products derived from the IndianaMap Statewide Ortho-LiDAR program.

Available today users can freely access all of Indiana's 2011 & 2012 LiDAR & Hydro-flattened DEM products covering 2/3 of Indiana [Central Tier & East Tier]. Note: The 2013 elevation data products for the West Tier of Indiana Counties will be available in early 2014. Indiana's updated OpenTopography Home page, which provides access to the LiDAR data is shown below, and can be accessed HERE.


The new Hydro-flattened DEM products menu for the Indiana Stateplane Coordinate System East Zone & West Zones are shown below. These DEM menus can be accessed by selecting the Rasters [East] or Rasters [West] options on the LiDAR Home page [see the arrow pointing to these options above the map on the above image].


The Stateplane East menu below also illustrates an area of interest being selected, output options for the Indiana DEM file format with the optional SRTM DEM product also selected.

Within seconds of clicking on the Submit button, a custom product result page [shown below] will display with active links to download the newly generated Metadata and DEM products selected.

IndianaMap has added 3 NEW layers to the Hydrology folder for “Water Bodies Lakes LocalRes,” “Water Bodies Rivers LocalRes,” and “Water Bodies Streams LocalRes.”

These three layers represent the latest release by the Indiana Department of Natural Resources (IDNR) of Local-Resolution National Hydrography Data covering Indiana. The new Local-Resolution NHD is being developed by AECOM for the State of Indiana Geographic Information Office (GIO) with support from the Indiana Geographic Information Council (IGIC) Waters Workgroup, and the USGS. This week the first eight [8] HUC-8 Subbasins covering Indiana are being published . These HUC-8 Subbasins are: 05120104 (Upper Eel), 0712002 (Iroquois), 05120105 (Middle Wabash-Deer), 05120107 (Wildcat), 05120204 (Driftwood), 05120205 (Flatrock-Haw), 05120207 (Muscatatuck), and 05120110 (Sugar).

The image below is an example of the new Local-Resolution NHD data displayed in blue over Indiana's new orthophotography. Notice that not only are flowing rivers, lakes, ponds, streams and ditches included in the new hydro-model, but even drainage swail lines in farm fields are being captured. This new "Local-Resolution" detail provides Indiana with a map and model of Indiana's surface waters beyond anything previously available.


INDIANA'S NHD HISTORY: Indiana's NHD data was originally developed by the USGS digitizing all of the hydrographic features published on their 1:100,000 scale USGS Topographic Map Series.


Later, the USGS developed a High-Resolution NHD dataset for Indiana by digitizing all hydrography features shown on their 1:24,000 scale (1"= 2,000') printed USGS 7.5 minute Quadrangle Map Series. Many of these maps are from 30 to 60 years old, and much has changed across Indiana that is not reflected in the High-Resolution NHD.


Indiana's new Local-Resolution NHD IS NOT being developed from an existing set of maps, but by using the best available Orthophotography and Elevation data to create a new hydrography map of Indiana. Data sources include Indiana's 2005 Statewide Ortho and Elevation data, and the new 2011 - 2013 Statewide Ortho-LiDAR data. The Local-Resolution NHD is being mapped at a scale of 1:2,400 scale (1" = 200') to a resolution of 6-acre sub-catchments. This Local-Resolution mapping is creating a new statewide map of Indiana's surface drainage that is 10-times more accurate than its High-Resolution predecessor and also adds more than 400% more streams to Indiana's NHD dataset than before. In the example below the High-Resolution NHD data is shown in Red and the new Local-Resolution NHD data is shown in Yellow.

The Indiana Spatial Data Portal (ISDP) archive provides the USGS digital topographic maps in two different products: the digital raster graphic (DRG) legacy product and the new US Topo product. The legacy DRG's are available in TIFF format (with or without the map border) and GeoPDF® format. The ISDP archive includes the DRG 7.5-minute (1:24,000), 30 x 60-minute (1:100,000), and the 1 x 2 degree (1:250,000) series maps.

The ISDP now offers all of Indiana's US Topo maps. The US Topo maps are constructed in GeoPDF® format from key layers of geographic data – orthoimagery, roads, geographic names, contours and hydrographic features - found in The National Map, which is a nationwide collection of integrated data from local, State, Federal, and other sources.

Layer Updates
We have recently updated 11 layers on the IndianaMap viewer. If you are a user of these data you can follow the links below to the IndianaMap Layer Gallery to access the preview maps, metadata, and download files for the latest versions:

The layer named “Coal Data NCRDS” (2010) has been updated with the most recent information published by the Indiana Geological Survey. It shows the locations of 13,722 public coal-resource data points in Indiana, derived from the National Coal Resource Data System (NCRDS). For more detailed stratigraphic information for each data point, please see the IGS’s Coal Stratigraphic Database (2011) and an ESRI ArcReader interactive application which are available through the IGS Bookstore: http://igs.indiana.edu/bookstore/details.cfm?ItemID=2145&Pub_Num=RP39

The layer named “Communications Broadband Coverage Wireline Wireless” has been updated with data provided by the Indiana Office of Technology and the Indiana Utility Regulatory Commission. Formerly, these data were split into two separate GIS data layers, but this update combines both “wireline” and “wireless” data into one data layer.


Updates have also been added for nine data layers that were provided by the Indiana Department of Environmental Management (IDEM), Office of Land Quality. The layers are...

Please note that the updated information for “Storage Tanks Underground” now includes the locations for leaking underground storage tanks, which was formerly published as a separate layer.

IndianaMap County Data Sharing Initiative Layers Updated:
The four layers that provide county-based framework data (including address points, street centerlines, land parcels, and Misc. Government Boundaries) have been updated. The layers were compiled from data maintained by various county agencies in Indiana, as part of the IndianaMap 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 FIFTEENTH set of data harvested through the ongoing DSI program by IDHS from local government sources on April 27, 2013. These layers are provided "as-is" and have not been quality control checked 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.

Institutional Control Sites Layer Updated:
The layer showing Institutional Control Sites (IDEM, Office of Land Quality) has been updated with information that is current as of June 5, 2013. IC’s are legal measures that protect human health and the environment by restricting property activity, use, or access when contamination is present.

I’m pleased to announce that Hamilton County is the latest participant in the statewide Data Sharing Initiative! The Hamilton County Board of Commissioners voted last week to allow the County’s land parcels, point addresses, street centerlines, and local administrative boundaries to be added to the IndianaMap.

The IndianaMap helps us to:
• Save time and money
• Increase efficiency, accuracy, and productivity
• Improve communication & collaboration
• Make better decisions and inform policy
• Support economic development
• Increase public access to government

Indiana has created a model for the nation of how to share and distribute state and local data sets. This benefits Hoosiers by saving substantial taxpayer funds by “reusing” the same maps and data many times, and benefits others by strengthening our national geospatial data holding.


Only four of our 92 counties are not taking advantage of this opportunity to increase the return on taxpayers’ investment in these data – Boone, Marshall, White and Warren. If you have contacts in these counties, please ask them to support this important initiative.
