NC OneMap will be unavailable from 4-6 AM Sunday, April 28.

US Topo maps are now available for download directly from USGS using a web map.

An important note about the image services for pre-2010 imagery from NC OneMap.

There have been many data updates to the NC OneMap geoportal.

There have been several data updates and new releases of note.

With the initial release of the NC OneMap Data Explorer, we are now looking forward to enhancing its' capabilities. We need your suggestions and criticisms so that we can make the Data Explorer even better.

Fast, easy data discovery with a map!  Announcing the NC OneMap Data Explorer—a new tool for previewing data in the NC OneMap Geospatial Portal.

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.

The historic imagery you used to find on the alphabetical data download page has been moved to the NC OneMap Geospatial Portal.

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.

There are a few Hurricane Irene related resources available to use.

In preparation for Hurricane Irene, we've centralized some pertinent services and shapefiles that you may find useful in advance of the approaching storm.

We've added some data updates to the NC OneMap Geospatial Portal.

We've recently added the ability to check the status of OGC (wms, wfs) and ArcIMS based map services to the Geospatial Portal. Now you can check if a service is available directly from the search results.

The new NC OneMap GeoSpatial Portal has been launched to support the recently release 2010 imagery.  As new resources are added, this will become the "one-stop shop" for users seeking geospatial information for North Carolina.

The 2010 imagery is now available online. Users can access the entire data set as a service or download a small area to their desktop.  Learn more about how to use this exciting new data set in this post.

There have been some data updates to the NC OneMap download page:

• Shellfish Growing Areas
• Significant Natural Heritage Areas
• Natural Heritage Element Occurrences
• Municipal Boundaries (Powell Bill)
• NC DOT County Boundaries (with and without shoreline)

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.

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.

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.
