As of this week, users of HPOWEB can now display the parcel boundaries of 25 counties across North Carolina!
These parcel data are provided as a service by NC One Map as their initial foray into creating a single, standardized parcel boundary GIS layer for the entire state. This is remarkable considering that every county tax assessor collects a slightly different set of data – and maintains these data in slightly different ways (think of how many different types of parcel numbers you’ve ever seen).
Read more below. This new functionality is only available in the Advanced User version of HPOWEB – not the General Audience version.
Within HPOWEB, you’ll notice that Parcels has been added as a new HPO Data Layer. It sits near the bottom between Boundary shading and Base Data. It is checked off when HPOWEB is first opened. Also notice that there are four sublayers.
It will be easier to view the Parcels layer (at least initially) after checking OFF the All NC HPO Data and Boundary shading layers. Then check ON the Parcels layer.
Each of the four sublayers automatically displays (and un-displays) at different scales. At a statewide scale, County Boundaries displays as dashed yellow lines and Counties Contributing Parcels displays as solid grey. Notice that the first 25 participating counties are spread out across the state and include both rural and urbanized areas.
As you zoom in, the Parcel Centroids (blue dots in the center of the lots) will display – they turn on at a 1:200,000 scale. Closer still, Parcels (blue lines marking the boundary of each lot) comes on – at a 1:40,000 scale.
Here’s an example of Trenton, NC in Jones County. You can click on any parcel to get a pop-up information box of basic data.
Be aware of some issues regarding the data:
- Consult the county tax assessor for the most current data
- Attributes like Year built can be inaccurate
- Exercise caution with the parcel numbers. For instance, the Durham County data references an old PIN, not the newer Parcel ID employed by the tax assessor.
In addition to clicking on individual parcels to obtain information, you can also use a new Zoom to Parcel tool that we have added to the toolbar.
If you know the parcel number of a property – but not where it is located – you can search for it using this tool. (Caveats include the current 25-county limit and the caution mentioned in the previous paragraph.)
To speed the search, we recommend adding the County name, too. The example in the tool suggests entering “Wake” and “1704706147”. If you do that and click search, you’ll find a match for the example parcel. Click the Zoom to button once to drill all the way down to the parcel.
We are uncertain when the remaining 75 counties will be added to this service, but we sure do appreciate what they’ve accomplished so far!
