Mike has set up a trial to the LandScan database from East View.
LandScan is a mapping application that provides gridded population data for the world. They’ve used satellite data to calculate population for small grid cells for the entire planet. This gives population researchers the ability to work with areas of a uniform size with data that is collected using one methodology, as opposed to working with census data from hundreds of countries that is collected using various methods for different time frames for places of widely varying size.
The product provides researchers with the ability to access the maps directly in GIS via the company’s servers, and also locally from individual files the vendor would provide us. Researchers can use the maps in GIS to extract data and overlay the population grid with layers of their own.
East View also provides a user-friendly web browser application that anyone can use. You can view population data broken down by age and gender for individual cells, countries, and first level subdivisions (states and provinces). There are a number of base maps for streets and topography that you can overlay the population data on.
The trial works on campus (without a password) from now until Sept 14th. Once you’re in the interface there is a link to a short video that gives you an overview of how it works. Access the resource here:
