O'Malley Library: DAsH: GIS & Mapping

What is it?

GIS or Geographic Information Services, allow you to place and analyze information spatially. You may be creating a map to visualize information to make historical or social science more tangible to the viewer. You may also be mapping your data to look for patterns that would only be visible on a map.

Map Programs

ArcGIS (MC Students, Faculty or Staff)
Use this link to get to IT's Knowledgebase guide on how to access to Manhattan University's licenses into ArcGIS. It is also available on computers on the first floor of the library.
ArcGIS
The industry standard, a very useful but complex tool. You can sign up for a free trial or limited online-only account for ArcGIS. We also offer it at the computer lab on the first floor in the library.
HistoryPin
Create mobile-accessible maps where you can pin photos and/or stories to a location and time.
Neatline
An add-on tool for Omeka that allows users to create timelines and maps as part of their storytelling. However, it doesn't allow for analytics or export of data, so better as a display option rather than long-term GIS projects
OpenStreetMap

QGIS
Open source GIS program. Less user-friendly but free and with a robust user community
