Transforming Spatial Data: The 2024 Data Harvest Review
The Indiana Data Harvest program is a collaborative effort between the Indiana Geographic Information Office (IGIO), the Indiana Geographic Information Council, and all Indiana County governments to collect, standardize, and share key GIS datasets. In its current state, the program focuses on address points, road centerlines, parcel boundaries, and various governmental administrative boundaries.
The datasets collected and shared through this program are critical for various operations at the local, state, and national level including 911, wayfinding, geocoding, and taxation, among many other uses.
In 2024, the program pivoted significantly by focusing on GIS data improvement rather than the typical submission process. In order to support various state and federal initiatives, especially statewide Next-Generation 911 (NG911) call routing, the IGIO deployed an online GIS data submission and validation portal called VEP. VEP detects possible anomalies in various datasets, mainly focused on NG911 data compliance. In the 2025 Data Harvest, the number of counties utilizing VEP will increase from 28 to 45.
GIS staff and vendors representing 28 of Indiana's 92 counties self-utilized VEP through the 2024 Data Harvest. A map showing which counties participated can be found below:
The 2024 Data Harvest led to the collection and standardization of 3,313,192 address points, 566,940 street centerlines, 3,677,250 parcel boundaries, and 14,656 administrative boundaries (including incorporated areas, emergency service areas, tax districts, and other boundaries).
The resulting statewide datasets can be accessed as a service, downloaded through IndianaMap, or accessed through the web services below.

Additionally, the statewide geocoding tools have been updated with new reference data. The links to the web services for these tools can be found below.
- Composite Locator: https://gisdata.in.gov/server/rest/services/Geocode/State_Geocoder_WGS84/GeocodeServer
- MultiRole Locator (the IGIO recommends using this option over the Composite Locator): https://gisdata.in.gov/server/rest/services/Geocode/State_Geocoder_MultiRole_WGS84/GeocodeServer

The IGIO team would like to thank the vendors and staff who participated in Phase 1 of the Framework Data Improvement Project and put a substantial amount of effort into transforming their data to the NG911 data model and reducing the number of potential data anomalies in VEP. Additionally, the IGIO team would like to thank the Polis Center at IU Indianapolis for their assistance with the collection and standardization of data from the remaining 64 counties.
A map highlighting the counties that did a fantastic job meeting the 2024 Data Harvest schema can be found below. This includes the new Platinum recognition level (shown in dark brown), which indicates full NG911 schema compliance with the addition of more detailed subaddress information.
