Interactive Map of U.S. Oil Imports Since 1973

RMI (Rocky Mountain Institute) provides a timeline-based interactive map depicting the U.S.’s historical imports of oil since 1973. Map controls can slide to specific dates and highlight five periods by major oil crises, including history briefs in the sideline. Map units can be displayed in oil or U.S. dollars. Map can also be put on auto-play. This is a well-done interactive map and interesting visualization of the flow of resources over time.

Rocky Mountain Institute is an independent, entrepreneurial nonprofit think-and-do tank™ that drives the efficient and restorative use of resources (from the RMI website).

Keep Your Eye on the Geospatial Revolution Project

Whether you are a lone GIS technician or a large GIS company, education and outreach is an ongoing challenge for everyone in the geospatial industry. The Geospatial Revolution Project was announced about a month ago and I was overly impressed with the goals and production value. It was too bad the wait-time was going to be long for final production. Today I received news that the GRP team will release short video segments throughout the life of the project rather than waiting for them all at the end. They are starting today by making the trailer downloadable. This is a high-quality video that will be useful with the general public and decision-makers (and family members who haven’t got it yet ;). Think about ways you might include the video clip in your community presentations, GIS day, school outreach, or the “About GIS” section of your website. See below for details – what a fantastic resource.

Ortelius is characterized by its ease of use and beautiful graphics capabilities for which Macs are known. Our new company anticipates the release Ortelius in the first quarter of 2009.

Simplify your Shapefiles

As mapping professionals, we often want more detail – the more accurate the better. But occasionally we need to simplify our maps (specifically our shapefiles) for presentation purposes or to speed up web map applications. Now you can very easily simplify your shapefiles online using MapShaper. I’ve used it and it was a breeze. Here is some info directly from their blog: “MapShaper is a free online editor for Polygon and Polyline Shapefiles. It has a Flash interface that runs in an ordinary web browser. Mapshaper supports three line simplification algorithms: Douglas-Peucker, Visvalingam-Whyatt, and a custom algorithm designed to smooth convoluted coastlines and spiky features.  The MapShaper project was conceived in 2005 by Matthew Bloch and Mark Harrower at the University of Wisconsin, Madison Geography Department. A paper [pdf] from the 2006 AutoCarto conference describes how MapShaper works “under the hood.”” Since it is a web application, you upload your shapefile, tell it what simplification program to run, and let it go. Thanks Matthew and Mark for a very nice app.
