Geographic Information Systems (GIS)
Geospatial data are electronic data that include some kind of location information, which could be latitude longitude coordinates, an address, a zip code or a county. These data are generally used in Geographic Information Systems (GIS), cartography, and remote sensing software packages. Data can be obtained from central clearinghouses (listed below), local organizations, and/or generated by researchers in the field.
From the interesting GIS Lounge portal: There is a distinct difference between GIS and Geospatial data, in that GIS refers more narrowly to the traditional definition of using layers of geographic data to produce spatial analysis and derivative maps. Geospatial is more broadly used to refer to all technologies and applications of geographic data. For example, popular social media sites such as Foursquare and Facebook use “check-ins” that allow their users the ability to geographically tag their statuses. While those applications are considered to be geospatial, they don’t fall underneath the stricter definition of what makes up a geographic information system.
The newly formed campus GIS Council is responsible for coordinating services and expertise. The lead player in this initiative is the Institute for Geospatial Analysis & Mapping (GEOMAP), housed in the Department of Geography-Geology at ISU, which has been providing synergy for faculty research across campus and offering unique learning and professional development opportunities for students.
The library has five ESRI workstations which are located in the uLab.

Some Helpful Tools:
Many online tools are best viewed in larger scale. The library has an Interactive Table which projects a PC screen onto a table-top, and also includes SmartBoard features such as highlighting, magic pen touch actions, and saving pages to your own ULID. This table-size viewing also faciltates group work when dealing with data sets, visualizations, and presentations.
SimplyMap -- a software product providing web-based mapping capabilities utilizing extensive demographic, business and marketing data. A tool that requires a far less intensive learning curve than the more powerful ESRI suite of GIS software. A personal account is required in order to Save your work on the central server.
Scribble Maps allows you to create quick maps with pins, highlighting, and annotations. It also allows you to use lines to calculate distances. This sample map that highlights a few locations took only a few minutes to create ... and can be inserted into web pages, blogs, or paper documents. You can also use Scribble to create Visual Indexes which contain links to other materials.
The following are simplistic descriptions to help a beginner understand some of the key terms and concepts used in GIS:
