What is GIS?   Watch a short 2 minute clip

What is ArcGIS? 

ArcGIS is a powerful desktop mapping software that enables users to analyze geospatial data and create their own custom designed maps.  A popular use of ArcGIS has been to map the wide variety of demographic information available from the decennial census.  Users can supply their own data or use the many datasets available from the GIS & Data Services - see Data Sources tab above.

Services We Offer

  • Software: GIS & Data Services offers Johns Hopkins University faculty, students and staff the opportunity to load a copy of the ArcGIS software for their use in teaching, research, or course work.  See Software Access tab above for more information.
  • Training: GIS & Data Services offers beginning and intermediate training through our Weekly Workshop series and the Welch Medical Library .  Customized class lectures can be developed for faculty who use GIS in their teaching.  See ArcGIS Training tab or contact information at right for a tailored class or more information regarding the workshops and classes offered.
