Public Data via FTP
The GIS Facility provides data produced by the DNR and data developed by research on campus downloadable through an FTP client. There are several free FTP clients that will work; we recommend using Filezilla for its simple interface. To connect you enter ftp.gis.iastate.edu as the host.
If you want to use a web browser, enter the syntax: ftp://gisftp%40iastate.edu:FTPisfunfirstname.lastname@example.org/
Restricted Data Access - Public Data
The GIS Facility provides data produced by the DNR and data developed by research on campus. This public data can be accessed directly from on campus by those people with an ISU username or from off campus, using the VPN. To connect to the data you have to map a path to the data location. Create a connection in My Computer (not a browser) to:
and be sure to specify your ISU username, if you have not logged in to your machine with that name. If you connect from off campus, you will need to use the VPN method, explained below.
Natural Resources Geographic Information System (NRGIS) Library
The NRGIS Library is a GIS repository developed and maintained by the GIS Section of the Iowa Department of Natural Resources. It is a collection of more than 20,000 geographically referenced databases. The purpose of the NRGIS Library is to improve the availability, integration, and analysis of natural resource information and improve decisions to carry out agency responsibilities related to the management, protection and development of Iowa's natural resources. The NRGIS Library is seen as a one-stop repository for all of Iowa's natural resource, geographic information. https://programs.iowadnr.gov/nrgislibx/
Restricted Data Access - ESRI Supplied Data
The GIS Facility provides data produced by ESRI that is included with our site license. Only those people with an ISU username will be able to access the data. To connect to the data you have to map a drive to the location. Create a connection in My Computer (not a browser) to:
and be sure to specify your ISU username if you have not logged in to your machine with that name (see image below).
If you are doing this from off campus, you will first need to connect to the ISU network with the VPN secure connection; if you do not do that first, the network mapping will not work. To find out about the VPN - http://www.it.iastate.edu/howtos/vpn
