In May 2012 a Tierra Plan web site developed for the Real Estate Data Exchange (REDx) won the Indiana Geographic Information Council (IGIS) 2012 Excellence in GIS Award in the Business or Commercial category for their Housing Activity Data web application. Tierra Plan worked with REDx to combine sales disclosure data with data on building permits, county parcel files and subdivisions into a Geode® application that gives users access a number of rich analytical reports and maps.
Timely and accurate real estate activity information in Central Indiana has historically been very limited. With the housing crisis over the past few years, the need for this information has become even more acute for builders, developers, lenders, and local governments. Sales disclosure records for new homes, home-sites and land have only recently become available in Indiana, and contain valuable data. The Real Estate Data Exchange of Indiana (REDx) decided to incorporate three of the most important datasets, and combine the newly available sales disclosure records with data on building permits and county parcel files into a web-based GIS. The database is updated quarterly, and covers eight central Indiana counties. Participating members have unprecedented access to detailed data on the housing market in Central Indiana, and use the data to generate feasibility reports for proposed subdivisions, land/home-site purchase due diligence and analysis of home-site inventories.
