The NC OneMap Geoportal is the central location to find geospatial data online for North Carolina. It operates on a distributed architecture which means that resources are not served from one central location. Instead, the data and services are hosted by a variety of data providers. The NC Center for Geographic Information and Analysis (NCCGIA), employer of yours truly, not only operates the Geoportal but also is a provider for several popular data sets (e.g., imagery, parcels, etc.). Starting in January, 2017, we will be making changes so that our services will only support connections using HTTPS. If you currently connect to any of our services via HTTP, then you will need to update your urls. Read on to find out why we're making this change and what you need to do to be ready.

The NC Parcels datasets (centroids and polygons) continue to be one of the most popular data sets served by NC OneMap. Containing over 5 million features, each one with up to 65 standardized attribute fields, the parcels data is regularly updated and available online as web services or for download. To date, downloads were available as county shapefiles. However, today we would like to announce that you can now also get the complete NC Parcels dataset in a single download.

We all know image collections can become large...very large. Whether it’s a personal photo collection or years’ worth of statewide imagery these data sets can get huge. Fortunately, there are different image file formats that allow for the balancing of accuracy, performance, and storage size. There isn't one format that is the best for every situation. However, moving forward, MrSiD fits the bill for NC OneMap imagery. This is now the format of files downloaded from the NC OneMap GeoSpatial Portal.

We are pleased to announce that the orthoimagery collected in 2015 for 24 counties comprising the southern Piedmont and Mountains section of North Carolina is now available online from the NC OneMap Geospatial Portal. As in previous years, this imagery is available both as a web service and via download. The orthoimagery is true color imagery and has a pixel resolution of 6 inches. This means you can zoom in to a scale of about 1:575 before the imagery starts to lose clarity. In order to conserve disk space the raw imagery was compressed during processing so image analysis (using the actual pixel values) is discouraged.

The NC Parcels have quickly become the most popular vector data set offered by NC OneMap. Based on customer feedback, the cyan color used to represent the parcels data (polygons and centroids)  has been replaced with magenta to provide better visibility across a wider variety of base maps.

We are pleased to announce that the orthoimagery collected in 2014 for the northern Piedmont section of North Carolina is now available online from the NC OneMap Geospatial Portal. As in previous years, this imagery is available as a web service and via download. The orthoimagery is true color imagery and has a pixel resolution of 6 inches. This means you can zoom in to a scale of about 1:575 before the imagery starts to lose clarity. In order to conserve disk space we compressed the raw imagery during processing. Visually you can't tell the difference. However, image analysis (using the actual pixel values) is discouraged. Click the Read More link below to read the full article.

Elevation data is now available on NC OneMap. The new data are derived from LIDAR collected by the NC Floodplain Mapping Program and processed by the NC DOT-GIS Unit. The resolution (cell size) of the Digital Elevation Model (DEM) is 20 feet. Using the DEM, we have been able to create several new data sets that may be used in a variety of applications. Samples of some the new data sets are shown below.

Have you gotten tired of searching a static html table for NC OneMap map services? Well, so have we. That's why we upgraded the Map Services Page so that you can now search for layers by keyword(s). Users can now also see whether the WMS map service is currently available, view the capabilities of the map service, and preview the layer.
