NC OneMap 2016 Imagery Ready for Use
1/30/2017 1:01 PM
We are pleased to announce that the 27-county 2016 coastal area imagery is now available. There was some disappointment when the imagery was taken off-line in early November 2016 (it had yet to be QC'ed and was brought on-line temporarily to help with Hurricane Matthew relief), but it is back to stay now. The info below will help you get to the data.
How can I get the new imagery?:
There are a variety of ways to access the orthoimagery, whether it be via download or streamed through an image service. They are outlined below. All the image services will respond to REST and OGC requests and are available in any projection supported by ArcGIS Server, unless noted.
Orthoimagery_2016: This image service contains only the 2016 coastal imagery.
Orthoimagery_Latest: This image service contains the latest imagery for any location in North Carolina. No imagery in this service is more than 4 years old.
Orthoimagery_Latest_cached: This is the same image service as Orthoimagery_Latest except the imagery has been cached for better performance. Note: This service is projected to WGS 1984 Web Mercator.
Orthoimagery_All: A time-enabled image service containing all the imagery available from NC OneMap.
Download county mosics: Consumers can download an entire county in MrSID format. This is the same data that is available in the image services. Note: This folder contains the most-recent imagery NC OneMap has for all 100 counties, not just the new 2016 imagery.
Download individual image tiles: The imagery is also available by dragging an area-of-interest on the map. Pick the year(s) of imagery desired, enter your email address, and a ZIP file will be generated and a link sent to your address letting you know when it is ready for download.
What are my options if I use a non-Esri product like Microstation or AutoCAD?:
- You can download the MrSID files to your desktop for use (links above) or stream in the imagery by establishing an OGC Web Map Service (WMS) connection within Microstation, AutoCAD, Carlson, or QGIS. The URL to use looks like this: https://services.nconemap.gov/secure/services/Imagery/[web service name]/ImageServer/WMSServer, where [web service name] is the name of (almost) any map or image service available from NC OneMap. For instance, the URL to stream the imagery in the Orthoimagery_Latest image service would be https://services.nconemap.gov/secure/services/Imagery/Orthoimagery_Latest/ImageServer/WMSServer. There are convenient YouTube videos to assist. Go to the home tab of the NC OneMap Geospatial Portal and look under "Tutorial Videos" in the lower-left of the page. If you are new to image services there is an NC OneMap FAQ page to get you started.
What counties are in the coastal 27-county area?:
- One-fourth of the state is flown annually, so no location in North Carolina will have imagery more than 4 years old. The statewide image-collection cycle has just started again for the second time, in the coastal area. This acquisition map details which counties will be flown when for this current cycle.
