URL's Changing for Several NC OneMap services

Overview

Did you do any online shopping over the Thanksgiving weekend? If so, chances are you checked to make sure that you were using HTTPS before paying (you did look didn't you?). As you know, HTTP is the protocol that is used to send data back and forth between your device/browser and a website. HTTPS does the same thing except that it also provides encryption so that any information that is being communicated between you and the website is secure. The goal is to make it impossible for someone to intercept your information while you're trying to score that 55" flat screen tv. The same principle also applies when a secure application makes a web service request from another provider. The provider needs to be able to also communicate securely so that it doesn't create a vulnerability. 

CGIA making the switch to HTTPS
All of the web services (map, image, etc.) currently hosted by CGIA that are provided to NC OneMap will be switching to HTTPS to support secure communication. This change will be completed on Friday, January 6, 2017. Services hosted by other NC OneMap partners will remain the same. In order to prevent disruptions, you are encouraged to make the changes now so that you can test connectivity.

Why?
There are a couple of reasons why we are switching our services to HTTPS. The first reason is related to the description mentioned above. In the last several months, there have been more and more cases where people have applications that require a secure connection. Implementing HTTPS will maintain security as these applications communicate with our services. Additionally, making this switch will make us more popular. Starting in 2014, Google started using HTTPS as a ranking factor in search results. The more people that know about our services the better. While this isn't the primary reason for us making this change, increasing our exposure through better Google search rankings certainly doesn't hurt.

What You Need To Do
If you are attempting to connect for the first time then please check out our tutorial videos on how to do that. Otherwise, here are links for ArcGIS Pro and ArcGIS Desktop that will show you how to connect. If you're still being affected by tryptophan from all of the turkey you ate, then there are screenshots below for version 10.4 (your mileage may vary).

  • ArcGIS (ArcCatalog, ArcMap):
    • Open ArcCatalog or ArcMap
    • Expand "GIS Servers" in the Catalog Tree
    • Click "Add ArcGIS Server"
    • Select "Use GIS Services" and click "Next"
    • Enter the new url for the secure services (highlighted) and click "Finish"
    • Confirm that the ArcGIS Server connection has been made in the catalog tree
    • Modify the data source property for layers in each map document so that they point to the new ArcGIS Server connection
  • CAD, QGIS, custom applications, etc:
    • We are an Esri GIS shop so our experience with other GIS or CAD is limited. However, the approach is the same. Locate each instance where you are connecting to one of our services. In the url string, change the portion from "http://services.nconemap.gov/arcgis/rest/services" to "https://services.nconemap.gov/secure/rest/services." For example, to change the connection to the "boundaries" service, modify the current connection string "http://services.nconemap.gov/arcgis/services/NC1Map_Boundaries/MapServer/WmsServer?" to "https://services.nconemap.gov/secure/services/NC1Map_Boundaries/MapServer/WmsServer?" Check the online help for your software to get more information.
