Accessing the Hub
The original intention for building the North Dakota GIS Hub was to serve state agencies as a lot of duplication of effort and data was occurring. With a centralized Hub in place, state agencies should be spending less time locating the best available data, giving them more time for their assigned responsibilities and allowing them to provide better support to their customers, which includes the public.
State security requirements, computer system performance, and protection of the valuable data assets on the North Dakota GIS Hub define the need for an infrastructure that addresses these three requirements. This infrastructure creates an environment that distinguishes how people inside and outside of state government access the Hub.
The North Dakota GISTC believes that the public can be directly served by the Hub, at the same time meeting the original intention for the development of the Hub and the infrastructure requirements. For this reason, state agencies will access the Hub using a direct connection or using the Web, non-state agencies will access the Hub using the Web.
ArcMap/ArcView - Direct Connect
In this method, you are connecting directly to the Geodatabase running on the State server. To connect to the Geodatabase, you must:
- Be a member of a North Dakota state agency, within the internal state network.
- Must Have a User ID and Password.
- Be using ArcGIS 9.0 and higher, or using ArcView 3.3 and higher.
- If you are using ArcGIS 9.0 or higher, you can connect with a few simple steps.
- If you are using ArcView 3.3 or higher, you can connect with a few simple steps.
ArcExplorer - Direct Connect
This free software provides a relatively simple set of tools that allows one to view, query, print maps using data from a variety of sources. ArcExplorer is a good method for accessing the GIS Hub and other ESRI data types such as shapefiles to those who do not have an ESRI tool, such as ArcView on their desktop. It supplements, but does not replace ArcView. When downloading ArcExplorer be sure to select the Java version. To access data on the GIS Hub, click on the "Add Layers" icon or menu item, expand the "ArcSDE" item, then double-click on "Add ArcSDE Connection" then entering the name of the server as shown in the ArcMap/ArcView - Direct Connect above. Please note that ArcExplorer is not able to utilize raster data on the GIS Hub.
GIS Hub Databases
The GIS Hub data reside on multiple databases. The organization of these databases reflects a combination of the type of data being stored and costs of the disk storage attached to each database:
| Database Name | Service Number | Comment |
|---|---|---|
| GISP | 5151 | Primary database with vector and raster data |
| GISGLO | 5152 | Government Land Office surveys (GLOs) |
| GISSPEC | 5153 | Specialized and agency-specific data |
| GISRAS | 5154 | Raster data |
You can use the same userid/password for all of these databases.
Web Services
Data on the GIS Hub is available as feature services and as image services to ESRI and non-ESRI GIS applications. For more information on web services and how to use them, please visit the Web Services page.
