Hamilton County in the US is using GeoSpatial Experts’ GeoJot field data collection app on an iPad to correlate street addresses with parcel coordinates. Initiated for tax assessment and E911 purposes, this photo project is creating the rural county’s first digital map database that matches property addresses to their correct geographic locations. Available from the Apple App Store, the product is a companion application created for exclusive use with the PC-based GPS-Photo Link photo-mapping software, also developed by GeoSpatial Experts. In Hamilton County, college interns walk from house to house taking photos of each one with the iPad 2. They then key in the house number, street name and street direction to keep the assessor’s tax database up to date. These attributes – along with the GPS coordinates – are permanently linked to the correct property photo by GeoJot. Back at the Assessor’s Office, the GeoJot files are uploaded to the GPS-Photo Link photo-mapping software running on a PC. The GPS-Photo Link software correlates the photos and attributes with their geographic locations and then outputs them to the ArcGIS database used for tax assessment. This database contains a parcel layer in which each property is precisely mapped to its correct location coordinates. GPS-Photo Link uses the photo coordinates to match the street address with its parcel in the database, merging the new attributes with the existing assessment information for the first time.
