DIVA-GIS DIVA-GIS is a free computer program for mapping and geographic data analysis (a geographic information system (GIS). With DIVA-GIS you can make maps of the world, or of a very small area, using, for example, state boundaries, rivers, a satellite image, and the locations of sites where an animal species was observed. We also provide free spatial data for the whole world that you can use in DIVA-GIS or other programs. You can use the discussion forum to ask questions, report problems, or make suggestions. Or contact us, and read the blog entries for the latest news. But first download the program and read the documentation. DIVA-GIS is particularly useful for mapping and analyzing biodiversity data, such as the distribution of species, or other 'point-distributions'. It reads and write standard data formats such as ESRI shapefiles, so interoperability is not a problem. DIVA-GIS runs on Windows and (with minor effort) on Mac OSX (see instructions). You can use the program to analyze data, for example by making grid (raster) maps of the distribution of biological diversity, to find areas that have high, low, or complementary levels of diversity. And you can also map and query climate data. You can predict species distributions using the BIOCLIM or DOMAIN models.

Mapping Sheets Another favorite Google Drive add-on of mine is definitely Mapping Sheets. With this add-on, you can make better use of any geographical data you may have in your spreadsheet. If you've ever wanted an easy way to quickly plot locations from your data onto a Google Map, this is it. drive addons8   5 Google Drive Add ons You Need To Use Using it is ridiculously easy. Just make sure you've got a list of addresses and other related data in your sheet, and then trigger this add-on. You'll see a form where you tell it what columns in your sheet to use for creating the map. drive addons9   5 Google Drive Add ons You Need To Use Once you submit it, the add-on creates the map right in the sheet for you so that you have a useful visualization of all of that data.

Google Correlate lets you see how your data relates to search queries Posted: 25 May 2011 11:27 AM PDT Influenza search - Google Correlate A while back, Google showed how Influenza outbreaks correlated to searches for flu-related terms with Google Flu Trends. It helped researchers and policy-makers estimate flu activity much sooner than with previous methods. Google Correlate is the evolution of Flu Trends in that now you can correlate search trends with not just flu cases, but with your own data or other search queries. The above, which you already know about, matches flu cases with searches for "treatment for flu." Similarly, the search phrase that correlates highest with "Toyota for sale" is "used Hyundai," as shown below. You can also see how your data is related geographically. For example, annual rainfall (left) strongly correlates with searches for "disney vacation package." Although, it looks like distance is a strong factor in the latter, which should be a reminder that correlation is different from causation. Google is careful to point this out in their FAQ and explanation of the tool. Nevertheless, it's fun to poke around and sometimes see the non-sensical correlations. For example, the strongest correlation with "flowingdata" is "how to scan a document," because the growth rates of both seem similar. There's also a search by drawing function. You draw a time series, and Correlate finds terms that best match that trend. In the below chart, I drew a line (blue) that had steady growth, but plateaued towards present day. What weird correlations can you find? [Google Correlate]

By Dan Nguyen Reactions to Osama bin Laden's death: Female and non-U.S. residents more ambivalent. Via the NYT Reactions Matrix By Dan Nguyen | Published: May 9, 2011 This (totally not-double-checked) analysis is a riff off of the excellent New York Times visualization (The Death of a Terrorist: A Turning Point?) of how people reacted to Osama bin Laden's death. In the days following the news, the Times asked online readers to not only write their thoughts on bin Laden's killing, but put a mark on a scatterplot graph that best described their reaction. The Times used the data to show the continuum of reactions from everyone who participated. I wanted to see how reactions differed across geographical location and gender. Includes details of his methodology (and a bit on that of the original NYT graphic)
