We are pleased to announce that on Wednesday, June 4, the GIS Atlas for Indiana will merge with IndianaMap.

Through the efforts of Jim Sparks, Geographic Information Officer, Indiana Office of Technology, a collaboration has been formed between the Indiana Geological Survey (IGS), the Indiana Department of Transportation (INDOT), the Indiana Geographic Information Council (IGIC) and numerous other partners to help fully realize the vision of the IndianaMap. Although the name and appearance of the GIS Atlas Web site will change to the IndianaMap, its functionality and content will continue to be enhanced and regularly updated, as before. The indianamap.org will soon become linked to the merged site.

"The IndianaMap - It's one map for Indiana, it's statewide, it's regional, it's local... it's yours."

It's true. The IndianaMap exists only because of the dedication and joint effort of our community of GIS professionals committed to working together to support our respective business needs. Whether for purposes of public safety, economic development, environmental investigations, tax assessments, or other uses, the unfettered access to hundreds of high quality GIS data layers through the IndianaMap is of enormous value to us all. The continued development and access to essential framework data is also essential. IGIC Framework Workgroups are pilot testing local data integration, developing a plan for updating statewide orthophotography, evaluating stewardship needs for statewide hydro, and much, much more. We are truly fortunate to have such a stellar statewide GIS community supporting this important initiative. Stay tuned and stay involved.
The Indiana Geographic Information Council is documenting the return on investment for the IndianaMap, and specifically for statewide high-resolution orthophotography. Your response to this questionnaire will contribute to the business case for the IndianaMap and future orthophotography program. Your input is essential.

:: Concurrent Session ::

Building the IndianaMap
This session will present the plan to build the statewide IndianaMap by integrating data sets from multiple state and local sources. This effort is a collaboration with the National Spatial Data Infrastructure (NSDI), a federal initiative to "acquire, process, distribute, use, maintain and preserve spatial data" at the national level. Come hear from the State Geographic Information Officer how Indiana is integrating GIS data and framework data to build the statewide "IndianaMap." The technical, legal, and administrative challenges inherent in such a comprehensive initiative will also be addressed.

Complimentary registration for all government employees!

A new era of data democracy has arrived, enabling tremendous improvements in land information systems and opening up a wealth of opportunities for the practice of community development and the management of community resources.

Geographic information systems (GIS) and Web services have dramatically expanded the ability to access, analyze, disseminate, and display vast quantities of data. These powerful technologies make it possible for cities, counties, and even regions to integrate their administrative databases and make parcel-level information available to the public via the Internet.

Community organizations that gather and analyze data, together with the national networks that support them, also play a crucial role in the democratization of data—serving as bridge-builders for technology, government, and the community. With this extensive information infrastructure in place, community development practitioners now have greater access to the detailed property data that are so vital for analyzing and monitoring changes in neighborhood real estate markets.

This report is part of a multiyear research and action project by PolicyLink, the Urban Institute, and the Lincoln Institute of Land Policy to advance the field of parcel data systems and their application to community revitalization and equitable development. It describes how pioneering organizations and partnerships are turning robust, integrated parcel data systems into powerful tools for guiding community change.

Case studies of five cities and regions—Chicago, Cleveland, Minneapolis–St. Paul, Philadelphia, and Washington, DC—detail some of the nation’s most promising applications of property-level information. They were selected to demonstrate how land information systems can be used to address a wide range of community development challenges on both an urban and regional scale.

GIS Specialist
The Madison County Council of Governments is looking for a qualified professional to serve as a GIS Specialist.
The debate over open access to public GIS data continues around the country. Recently, the University Consortium for Geographic Information Science (UCGIS) has endorsed an Amicus Brief filed in California involving questions of geographic information access. The Santa Clara Superior Court agreed with arguments presented by the California First Amendment Coalition that Santa Clara county should charge minimal cost, impose no restrictions in access to its geographic information "basemap". Prior to the suit the Santa Clara county charged over $100,000 for its public data. The county has since lodged an appeal which will be heard by the state Appeals Court. The amicus brief will be considered in the appeal. Further details are available at the following web site: http://www.cfac.org/content/litigation/santaclara.php#LD . The Amicus Brief is available at: ftp://joffes.com/Amicus%20Brief%20final-8.pdf.

Another new interactive map—the Indiana Historical Aerial Photo Index (IHAPI)—is now available to help identify and retrieve historical aerial photographs. More than 950 large-format photomosaic index maps in the IGS archive were scanned and georeferenced, and then mosaicked to produce 466 county-based images dating from the 1930s to the 1980s. From these images, a point index was created showing the upper-right corners of 113,035 individual historical aerial photographs.


IHAPI allows users to easily locate a site of interest and determine unique identification numbers for individual photos. Copies of the photos can then be ordered from the various archival collections where they are housed, including the IGS archive. (The actual historical aerial photos cannot be downloaded using IHAPI.) A narrated video tutorial is also available on the Web site.

April 21, 2008 - By February 2009, any Landsat archive scene selected by a user will be processed, at no charge, automatically to a standard product recipe and staged for electronic retrieval. In addition, newly acquired scenes meeting a cloud cover threshold of 20% or below will be processed to the standard recipe and placed on line for at least three months, after which they will remain available for selection from the archive. Details can be found in the USGS Technical Announcement http://landsat.usgs.gov/images/squares/USGS_Landsat_Imagery_Release.pdf (66.8 KB).
