Population Explorer is a Google Maps based tool that can estimate the population of any area on Earth, down to an area of 1km2.
Draw a polygon anywhere on the Earth and Population Explorer will provide an estimate of the population within the defined area. I’ve tested the tool by selecting areas that I know, such as London and the UK, and I’ve also tested it by searching for estimates in deserts and the sea. From my limited testing Population Explorer does seem to return accurate population estimates.
The results of each search displays the total population, the population density, the number of males & females, the age structure of the population and population growth estimates.
Interested in taking a spatial mapping course free form Penn State University? Sign up and follow along! This is the first week that it is being offered and so far over 3,000 people have signed up. This is a great way to learn all about the spatial perspective and how to use ArcGIS in every day life.
If you have no idea what ArcGIS is, check it out, it is quite amazing. Imagine a whole bunch of layers of data that you can toggle on and off to see if there are any correlations between the phenomenon. Ok, I know that didn’t sound so amazing-but liken with toggling a map of McDonalds locations and low income housing. Do you get me now?
Maps are for everyone and you don’t need a background to start, just an interest in maps. Here is a copied and pasted section of who this class is intended for:
Wired: Who’s the intended audience?
Robinson: Novice folks who are maybe coming out of high school in some cases, or lifelong learners who are interested in maps but have never taken a class. My core motivation was to design a course for people who use maps but have never made one of their own. It’s an entry-level thing. It’s the gateway drug to mapping.
Esri (GIS Mapping Software, Solutions, Service, Map Apps, and Data) just launched an interactive site that allows users to compare/contrast map data between 16 major cities (so far). Themes that can be compared include:
- Commercial/Industrial zones
- Housing Density/ Population Density/Senior population/Youth population
- Public space
- Urban Footprint
- New development
This is what happens when psychology and geography come together. I love this comic.
