Mapping the 2010 U.S. Census –

Mapping Data

Mapping the 2010 U.S. Census – I keep returning to this fine example of web mapping which the NYTimes has created for the 2010 Census results. The content is fascinating and the interface is great in performance (speed) and options. You can’t download data but that’s not the point; you can easily explore the changes in racial, ethnic and population density in the last decade. The US Census Bureau has the 2010 Census data as shapefiles available for downloading as well as many different tallies of new and changed geographic entities but no beautifully rendered interface. That remains the NYTimes’ strength.


iNaturalist- Explore, Record & Share your Observations

Mapping Data

iNaturalist.orgIf you are not familiar with iNaturalist, go check it out! There is a lot of functionality here with a smooth interface that sets it apart from other citizen science websites. iNaturalist satisfies the naturalist in all of us and allows you to share and communicate with a growing community of observant nature lovers around the world.

Recently an iphone app for iNaturalist has been released so you can make your observations on the go, and post your info when you are back in wi-fi or cellular range.

A class at SFSU will start to use it to record their observations on their fieldtrips to the Angelo Reserve in northern California.

The Places feature is a great way to start cataloging observations for specific protected area and building a way to inventory and monitor species. If you don’t see a checklist for your local park, you can easily start to build it yourself.

The future of mobilized biodiversity data is here and will be exciting to see how this and other efforts to capitalize on collection data housed in natural history collections worldwide.

Google Maps Tools

Mapping Data

This is actually “old” news but at a recent georeferencing workshop we gave, I was in the awkward position of having an outdated slide! As posted here under the Map Tools tab, we recommend Google Maps as an efficient and easy georeferencing tool to affix coordinates to a site. Further, we used to suggest third-party mapplets to enhance these tasks. My favorites were: Lat/Long Tool, and just for fun, Dig a Hole Through Earth. I used the former a lot since you can create a nice long list of coordinates in any format you need (DMS, DD, etc) then copy/paste them all into a spreadsheet of your localities. However, Google decided to deprecate the whole program of independent developers adding in Google Maps functionality and instead shove them onto little websites of their own.

Google Earth Engine

Earth, Mapping Data

Google Earth Engine. Unveiled in Cancun, Mexico, at the International Climate Change Conference, Google announced its latest planetary visualizations. From Google’s blog: ” Google Earth Engine is a new technology platform that puts an unprecedented amount of satellite imagery and data—current and historical—online for the first time. It enables global-scale monitoring and measurement of changes in the earth’s environment. The platform will enable scientists to use our extensive computing infrastructure—the Google “cloud”—to analyze this imagery.”

You can browse through different layers in the Data Catalog tab then press Open in Workspace, an adjacent tab for a Google Maps interface. The Gallery tab embeds the 3D Google Earth to view and interact with Featured Data.

I was struck by the forest cover loss in the last decade in the Congo– the product of over 8000 Landsat images!

This is necessarily collaborative, to make accessible these kinds of data, the breadth of historic remote sensing data and products from remote sensing data, and more importantly invites collaboration across many disciplines. So I am looking forward to see what happens here. Congratulations to Rebecca Moore!

Digitally Mapping the Republic of Letters –

Mapping Data

Digitally Mapping the Republic of Letters – This is a fascinating way to map social and political connections both spatially and temporally. (It’s also a testimonial to the nineteenth century postal service!) I find the emerging digitization of historic data (especially in the humanities) exciting and would love to see this similarly in the history of science.  How geographically clustered were schools of thought on ecology and evolution? Was there really an East/ West Coast divide in the early 20th century? Some would look to the mentoring system as a metaphor for familial lineage and influence but active correspondence would likely be more revealing and significant.

Thanks Jeni for pointing this article out!

And Happy GIS Day!

Wikileaks: Every Iraqi Death Mapped

Mapping Data

This map is powerful in its stark facts. It’s a simple point map on a Google base map but every point is report of one or more deaths, either armed forces, civilian or enemy, attributed to enemy fire, criminal activity, IED hazard, friendly fire, etc.  These categorizations raise more questions than they address, of course, but the toll on civilians is plain when you navigate the deaths. Major thoroughfares and intersections seem particularly dangerous to armed forces and civilians alike.
