Map Collections at UCD and on the Web: Show Your Data on a Map
Are you creating maps for your research?
The use of maps enables the visualisation of data and helps to make an argument easier to understand. As well as making a lasting impression they provide an eye-catching way to make data coherent, to see patterns emerge and to communicate research findings.
To encourage the use of maps in a wide variety of disciplines and to inspire our own PhD students and researchers to create maps without requiring a big learning curve we run workshops on some of the mapping tools as shown on this page.
Show your Data on a Map : Creating a Datawrapper Symbol Map
With Datawrapper's free service you can create different types of maps. This guide shows you how to create a symbol map which you can either use interactively on a website or blog, or save as an image to include in a thesis or report. With this type of map you can show numerical / quantitative data for specific places. For example:
- Show locations of earthquakes and size the symbol by their magnitude
- View the top twenty busiest airports in the world by numbers of passengers
- See all cities with urban populations of more than 2 million people
- Visualise levels of ammonia emission measurements in each EU country
Show your Data on a Map : Creating a Datawrapper Choropleth Map
With Datawrapper's free service you can create different types of maps. This guide shows you how to create a choropleth map which you can either use interactively on a website or blog, or save as an image to include in a thesis or report.
Choropleth Maps – these are thematic maps where you can use colours to display statistical data by colour or pattern for geographic areas, e.g. countries, constituencies, counties, provinces, administrative areas, etc. Choropleth maps use different shades of colour or different colours to display the quantity, value or category in the selected areas.
For example, by using a darker or lighter shade of colour or different colours you can:
• show the population density for each Irish county
• depict highest / lowest literacy levels in each country around the world (as shown in this UNESCO report)
• visualise USA states by Democratic / Republican governors
• see hectares of forestry by each state in Brazil
• represent on a map African countries which have or have not eradicated TB
How to Create an Online Timeline using Timeline JS
Mapping a World of Cities is another example of a Knight Lab Timeline
'Covering four centuries, these maps show how world cities changed alongside the changing art and science of cartography'
This is a timeline of historical and vintage maps of cities around the world. The project is the result of a collaboration between ten U.S. map libraries and collections, including the David Rumsey Map Collection, the Library of Congress and the Harvard Map Collection.
