As Hurricane Irma potentially impacts North Carolina, CGIA, in coordination with the NC 911 Board and i-cubed, has temporarily made available the

2017 orthoimagery for the Eastern Piedmont (green area) .
By nconemap on 3/3/2017 10:16 AM

Geospatial services hosted by NC CGIA (e.g., imagery, parcels, etc.) will be down due to scheduled maintenance beginning Thursday (3/9) at 5:00pm until Friday (3/10) at 7:00am.

The 2016 coastal area orthophotography that was temporarily available for Hurricane Matthew relief is now part of the permanent NC OneMap imagery collection.

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 temporary services depicting the 2016 orthoimagery that were made available during Hurricane Matthew will be deactivated on November 2, 2016. Look forward to their reappearance in February 2017 after the imagery has completed the full quality control process,

The real damage from Hurricane Matthew is being realized long after its departure from North Carolina. NOAA is collecting imagery to assist in damage assessment and recovery efforts. NC OneMap is also providing the latest pre-event imagery for the area, updated parcels for several counties in the affected region, and a online viewer that combines all this information for easy viewing.

NC Parcels is a statewide dataset of parcel information with standardized attributes for North Carolina. This data is regularly updated and, in response to Hurricane Matthew, has been recently updated for several counties (as recently as October 5, 2016) that are impacted by Hurricane Matthew. The data is available online from NC OneMap.

As Hurricane Matthew potentially approaches North Carolina, CGIA, in coordination with the NC 911 Board, has temporarily made available the 2016 orthoimagery for the coastal plain.

Imagery. We know you love it. We do too. Heck, who wouldn't? Free, high resolution imagery at your fingertips. What's not to love?  Well, there may be one thing. Even though, we have increased the amount of data that can be downloaded at a single time, this is still too restrictive for some you. So starting this week, we have added the ability to download the most recent imagery by county from the GeoPortal.

By nconemap on 6/3/2016 12:51 PM

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.

By nconemap on 5/31/2016 2:36 PM

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.

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.

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.
