Defining Cartograms

Cartogram Central
http://www.ncgia.ucsb.edu/projects/Cartogram_Central/index.html 

TYPES:

NON-CONTIGUOUS CARTOGRAMS - geographic objects do not have to maintain connectivity with their adjacent objects

CONTIGUOUS CARTOGRAMS - true- topology is maintained (the objects remain connected with each other) but this causes great distortion in shape

DORLING CARTOGARMS - maintains neither shape, topology nor object centroids

Spatial Data Inventory

This week's lab exercise will provide students with a hands-on experience conducting an inventory of a thematic feature on or near Temple University's Main Campus. There is a long tradition of field work to gather spatial information that includes surveying, identifying features, and describing the attributes of features found in the landscape.

We will review the use of Google applications, including documents and maps, to depict the locations of features that you identify through your survey. We will also discuss examples of inventories that can serve as a model for your survey exercise.

Here are some links to thematic maps that may be of interest related to the themes we discuss in class.

Creating Google Maps

You will be creating maps using Google Maps from the survey data set you are creating.  Here are resources for learning more about how to make Google Maps.

Google Maps Mania is a resource that shows how users are creating maps, adding new applications, and integrating Google Maps with other social media tools. Here are a few posts from the site that illustrate the types of mash-ups, or map creations, you can make with Google Maps.
