An article from the Washington Post online edition (free registration required) argues that, now that most scientists agree that human activity is causing global warming, the debate is now beginning to focus on the ‘tipping point’ or point of no return when we can no longer reverse the changes that are taking place. Determining when such a point may occur given the current rate of warming will be essential in figuring out what the necessary reduction in greenhouse gases will need to be to prevent the catastrophic outcome of unchecked global warming.
There are many examples of how quickly geospatial technologies are being adopted around the world, especially in the rapidly-growing countries of Asia. This article from The Times of India discusses the deployment of GIS and GPS technology in the main control room for the Mumbai , India police force.
mapz posted a link to an article titled “Web GIS in practice IV: publishing your health maps and connecting to remote WMS sources using the Open Source UMN MapServer and DM Solutions MapLab“, thatÃ‚Â comes complete with a tutorial.Ã‚Â The tutorial is a 14 page document that walks you through downloading the software, installing on a windows box, and getting a demo running.Ã‚Â Complete with lots of graphics and links to open source web mapping software.

I was pointed by Tim, one of our listeners, to a manifesto for open data access in the UK.Ã‚Â If any of you work in the UK regularly or have wanted to do work in the UK, you know that the Ordnance Survey’s data licensing is pricey.Ã‚Â This leaves some of us in the US with sticker shock since we have access to a wealth of inexpensive, if not free, data. Ã‚Â So if you would like to add your name to the list of those who are for open access to UK state-collectedÃ‚Â geodata then head over and check the details.
Open Access to State-collected Geodata
It has been a while since the BBC gave us something bloggable. This gem is definitely worth blogging and chuckling about. Sea level is rising…OK. The last 50 years moving at an accelerated rate…OK. But the fact that we have evidence of the Little Ice Age ending just before this study begins makes it all a bit amusing. Of course some of the ice captured in the arctic regions during this time would be released with the following warming in the mid to late 1800s.
I want to see more studies comparing the altithermal (you know, around 8000 BP) to the present sea levels.

The Carbon Project, which focuses on development of Open-Geospatial .NET applications, announced it has become a member of the ESRI Business Partner Program, and will develop interoperability extensions for ArcGIS. The first extension will be CarbonArc, which will enable seamless use of OGC services in ArcGIS. The first module, CarbonArc Lite, is already available for download from The Carbon Portal website.
Tim Warner here at WVU just forwarded us the good news that Landsat 5 has resumed acquisition operations for the continental US and international data acquisition will be coming back online in the next few weeks. Engineers were able to make adjustments to Landsat 5’s solar array to give it enough power to continue its mission. This is definitely good news for the remote sensing community.
The press release is available at the Landsat Mission website
The Japanese Advanced Land Observation Satellite (nicknamed “Daichi’) was launched on January 24th, after two delays for technical problems. According to the Japan Aerospace Exploration Agency (JAXA), The satellite will be used for mapping and to monitor disasters and environmental change around the world.
