Mapping and georeferencing is closely related to data visualization, but is dedicated to data that has a spatial component. This guide is not intended to cover the breadth of Geographic Information Systems (GIS) or the kinds of analyses that can be done with those platforms. It is intended to provide basic, "getting started" tools for non-Geography students and faculty who are interested in adding basic mapping methods to their research toolbox.
See the data visualization section in this guide for more general information... and before diving into map creation, be sure to check out our Data & Statistics guide and our Maps & Atlases guide for information understanding maps and finding sources for data.
As with other areas of this guide, our focus here is on free or inexpensive, accessible tools for those interested in working with maps and spatial data.

Geocoding is the process of turning basic information about a location (e.g. a place name or an address) into longitudinal and latitudinal coordinates that can be used to plot those locations on a map. The tools below can assist with this work.
free | input: address data | maximum of 2500 entries
free | input: addresses, postal codes, intersections in the USA and Canada | maximum of 2500 entries per day
free | input: address data | code 1 entry at a time
paid service - $0.004US per entry, minimum $10 order | input: addresses
free, but app keys for Mapquest/Bing/Google required | web-based | input: addresses
Tutorial; QGIS is free and open source | input: place names
Georeferencing is the process of taking existing image data (such as a scanned map, airphoto, or blueprints) and "anchoring" it in space by pinning it to specific geographical coordinates. Sometimes an image must be "warped" or reshaped to align it properly with latitudinal and longitudinal information. To do this work, you might try the tools below.
