Standardized Parcel Data Now Available from NC OneMap
4/30/2014 8:21 AM
The NC OneMap team is pleased to announce that standardized parcels are now available for 25 of 100 North Carolina counties. This data is available as both points (centroids) and polygons (boundaries) and contains over 60 data attributes.
25 counties and Eastern Band of Cherokee Indians are initial participants
Getting the data
The parcels can be consumed from web services or downloaded in shapefile format from the NC OneMap Geospatial Portal. The web services are being offered as both map and feature services (ArcGIS, WMS, WFS). There are scale thresholds set on the data so you will need to zoom to 1:200000 before you will start seeing the parcel information. The GeoSpatial Portal can give you detailed information about the map and feature services along with the downloadable data.
If you need help in connecting to the services, check out our tutorial videos to get you started. You can also go directly to our REST page to get connection information (look for "NC1Map_Parcels") .
Parcel data is represented by points and polygons
Parcel data is consistent and offered in a variety of formats
How the parcels are standardized
The GICC Working Group for Seamless Parcels developed an online tool, called the NC Parcels Transformer, to allow local government parcel data owners/custodians to upload their cadastral data and match their attributes to those in a core standard. Once standardized, the data is synthesized into a single data set and made available from NC OneMap. It is important to note that the translator only deals with attribute fields and does not address parcel geometry (i.e., edgematching) between counties.
The 25 counties are the first iteration of this effort. CGIA is leading an effort to get more county parcel data online in the months ahead and develop a truly statewide parcel dataset comprised of all 100 counties.
As always, please feel free to provide us any feedback you may have.
