Over 2.5 million point addresses covering almost 70 of Indiana's 92 counties have now been published from the IndianaMap on OpenAddresses.org. Similar to OpenStreetMaps.org, OpenAddresses.org is an open source web portal for the management of Open worldwide geolocated postal addresses.
The map shown above zoomed into Indianapolis/Marion County can be viewed on-line HERE.
OpenAddresses is currently in BETA and not all of the functionality is currently in place. To date, Indiana is the third U. S. State to have joined this effort, joining North Carolina and Arkansas.
