Digital Scholarship and Digital Humanities: Mapping and Geo-Referencing

Resources and information for students, researchers and faculty who are incorporating technology into their research, scholarship, and teaching.

Mapping and Georeferencing

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.

General Maps

Google My Maps

free | web-based | easy to learn

"My Maps" lets you create customized Google Maps with your own annotated points or areas of interest, either by inputting them manually or be importing data from other sources.. You can associate tabular data, directions, distance measurements, text, and other media with shapes and points. You can also export map data in KML and KMZ formats that can be imported into other tools (such as Google Earth)

Google Earth

free | web-based, Windows, Mac, Linux | slight learning curve

Google Earth generates 3D representations of maps featuring satellite imagery that can be annotated and built into virtual "tours" or stories.

Scribble Maps

free version allows 5 maps; paid version available with many more features | web-based | easy to learn

Similar functionality to Google Maps, with a some extra drawing and data export features. The free version allows you to create up to five maps that you can embed in other websites.

Carto

free for 12 months; then expensive | web-based | learning curve; more of a full GIS than a basic mapping application

Carto's online mapping platform has grown into a fully-fledged online GIS system, incorporating numerous real-time data sources (everything from traffic to earthquakes) and analysis tools. Extremely powerful... and extremely expensive after your free 12 months of access expires.

Open Streetmaps

free, crowdsourced | web-based | creating maps requires software skills

This is a free and open alternative to commercial applications like Google Maps. Information available in Open Streetmaps is crowdsourced and anyone can add or revise data. You can use the default application in the same way as Google Maps, but you can edit information and you can also use Open Streetmap to export maps, import/export data to GIS tools, and more.

Mapbox Maps

free tier for basic features | web-based | moderate learning curve

Very flexible map building tool, geared towards developers, with a generous set of free features. Combines a flexible style editor with a robust dataset import/creation tools. Resulting maps can be embedded in websites (using the Mapbox GL JS toolset) or integrated into software and mobile apps.

Harvard WorldMap

free | web-based | easy to use

On online, open source portal for creating maps. Referred to as a "GIS light" option for scholars who want to do more than is possible with basic online mapping tools (such as using large datasets) without relying on a full desktop GIS application.

GPS Visualizer

free (ad-supported) | web-based | easy to use

A free, ad-supported tool for generating maps from GPS traces and waypoint data in various formats (including spreadsheets and tabular data).

Story Maps

Story Maps

ArcGIS StoryMaps

free for basic use; subscriptions available | web-based | easy to learn

Build visually-appealing map-based narratives with a drag-and-drop interface that lets you include text, images, and video alongside maps.

KnightLab StoryMap JS

free | web-based | easy to learn

Use a series of "slides" to tell a map-based story. Content can include text and media, and can also link to content from YouTube, SoundCloud, and other sources.

Google Earth Tour Builder

free | web-based | easy to learn

Build a stop-by-stop tour that takes uses to different locations using Google Earth's 3D interface.

Geocoding

Geocoding

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.

Texas A&M Geocoding Service

free | input: address data | maximum of 2500 entries

GeoCoder.ca

free | input: addresses, postal codes, intersections in the USA and Canada | maximum of 2500 entries per day

Open Geocoding

free | input: address data | code 1 entry at a time

Maplarge Geocoding Online

paid service - $0.004US per entry, minimum $10 order | input: addresses

GPS Visualizer's Geocoder

free, but app keys for Mapquest/Bing/Google required | web-based | input: addresses

Programming Historian: Geocoding using QGIS

Tutorial; QGIS is free and open source | input: place names

Georeferencing

undefined

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.

Map Warper

free | web-based | tutorial available

Programming Historian's Georeferencing using QGIS

Tutorial; QGIS is free and open source | web-based | easy to learn

Scholars' Lab's Georeferencing using ArcGIS

Tutorial; ArcGIS license required
