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.

As GIS professionals, we have all experienced it at some point in our careers. We've just finished a project and ready to call it a day. The only thing left to do is let your boss and coworkers give a cursory review of your work. And then it happens. Everyone offers their opinions on what color you should have chosen to represent those fire hydrants. "The best color is strawberry-chartreuse, not red." Just when you thought you were done you now have to somehow develop a consensus on how to best cartographically style data in your map or application. Ahh, the joy.  This is even more difficult when trying to pick styles for data contained in map services.

Default map service symbology rarely works in all situations.

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.

Statewide parcels in North Carolina? Not going to happen, no way. Well, guess what?  We did it. The state now has a seamless statewide parcel dataset available online. NC Parcels is a reality.

The effort to create a seamless statewide parcels dataset continues to gain momentum. We are happy to announce that 36 additional counties have recently been added. That takes the current total to 61 counties that are now available from NC OneMap.

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.

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 attributes.  As with all NC OneMap data, this data can be consumed from web services or downloaded in shapefile format from the NC OneMap Geospatial Portal. 

NC Parcels provides standardized attribute data

All of the NC OneMap web services have been restored. If you continue to experience issues please contact us.

A server crash has caused the NC OneMap services to stop functioning. This includes the map and image services, and services supporting the imagery download. We hope to have all services back up soon. We are sorry for the inconvenience.

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.

The NC OneMap Team has two upgrades scheduled for the next two Fridays (10/14 and 10/21). This will require that the GeoSpatial Portal be taken offline from 5-8pm.  In preparation, we are also going to disable the download imagery functionality starting at 4pm both days.  We're doing this to try and avoid someone making a download request and it getting dropped during the upgrades.

In case your interested, the upgrades include an update to the GeoSpatial Portal software that will allow us to more efficiently manage the application. Also, it will improve the processing required to package the imagery into a zip file.  Finally, we will be upgrading VMWare (virtual machine software) that runs the system. Both of these upgrades will improve the capacity and speed at which we can service your requests.

As always, please leave your comments on the blog or email us.

Adobe Flex based applications sometimes need to connect to information, services, or resources on other websites or domains. Security vulnerabilities typically prevent this unless special permission is granted by the server providing the resource. The NC OneMap servers also employ this protection but there is a way to gain access.

The North Carolina Department of Transportation has flown damaged areas of the Outer Banks due to hurricane Irene multiple times. That data is now time enabled and is available as an image service.

We've recently added a series of videos on how to use the NC OneMap GeoSpatial Portal to Youtube.  In the future, we will be looking to add more videos on how to use the GeoSpatial Portal and take advantage of the resources it provides. You can take a look at the videos by visiting the home page of the GeoSpatial Portal.

The GIS folks at NC Dept. of Agriculture and Consumer Services/Emergency Programs have been busy. They are bringing us 2 more WMS map services - USGS 1998 CIR DOQQs and USGS DRGs. Both are available from the NC OneMap map service discovery page. Thanks to Dan Madding and Ed Shipman for providing these.
By nconemap on 2/9/2011 2:51 PM

In addition to the three WMS map services for NAIP imagery that we added in January,  the Department of Agriculture has provided four more WMS map services to NC OneMap. With these new services there is now NAIP imagery for 1998, 2006, 2008, 2009, and 2010 in either true color or infrared (IR).  Check them out using the new map services discovery page. Enter the search term "NAIP."

Thanks to Dan Madding, Ed Shipman, and the Department of Agriculture for making these additional services available.

By nconemap on 1/14/2011 3:11 PM

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.



By nconemap on 1/14/2011 3:08 PM
We've recently added three new WMS map services for NAIP imagery.  There are services for 2008 and 2009.  There is also a map service that has NAIP 2010 true color overlaid with higher resolution county imagery.  Check them out using the new map services discovery page.

Thanks to Dan Madding and the Department of Agriculture for making these services available.

There have been a few updated data layers that are available for download from the NC OneMap download page. They are:
