In GeoEye’s gallery are numerous high resolution images of locations across the globe. The Eastern Algerian portion of the Sahara is an otherworldly place, a region of great diversity with endless stretches of sand dunes and rocky platforms that can reach more than 2,000 meters. The Tassili n’Ajjer “Plateau of the Rivers” National Park is a vast plateau in southeast Algeria at the borders of Libya, Niger, and Mali, covering 72,000 square kilometers.

Friday, February 10th, 2012John Snow’s 1854 Cholera Map comes to life with the CartoDB platform
Thursday, February 9th, 2012John Snow created a map of a cholera outbreak in the district of Soho, London in 1854, which helped to convince authorities that the disease was caused by water ( in particular, it originated from one pump in Broad Street). The CartoDB platform allows you to map data and develop location aware applications very easily. This example of John Snow’s Cholera Map of London presented with CartoDB demonstrates how CartoDB can quickly combine different data types, then display them on a map.
President Obama praises young scientists at White House Science Fair
Tuesday, February 7th, 2012President Obama’s closing words to young scientists at today’s Science Fair held at the White House: “I’m proud of you. Keep up the good work. And don’t let any of those robots wander too far.”
LiveLink integrates GIS with remote sensing and image processing
Tuesday, February 7th, 2012Mladen Stojic, vice president Geospatial, Intergraph, talked about their new Live Link product which integrates Intergraph GeoMedia objects into ERDAS IMAGINE. Intergraph is a wholly owned subsidiary of Hexagon acquired in 2011. What this product offers is what customers have been asking for – an integrated approach to desktop workflows, combining the desktop GIS capability of GeoMedia integrated with the raster remote sensing and image processing capabilities of ERDAS IMAGINE.
How to measure the world’s largest cities
Friday, February 3rd, 2012Scholars are having trouble measuring the world’s largest cities – largely because the terms the cities are measured by differ from place to place. They have come up with a total of 30 largest cities in the world.
Richard Greene, associate professor of geography at Northern Illinois University in the United States, says even the most authoritative list, from the UN, “compares apples with pears”.
Saving changes to your default raster type [ArcGIS Resource Center]
Thursday, February 2nd, 2012For those who have made any changes to the default raster type, you will probably want to save your changes. This way you can re-use your custom raster type if you want to load additional raster data with the same properties and functions.
To save your custom raster type, click on the General tab. At the bottom of this tab, you will see a Save As button. Click the Save As button, and save it in the location where you keep all your custom raster types.
Speed, notification, more file formats in the new FME 2012
Friday, January 27th, 2012
Vice President of Software Development and Co-founder of Safe Software, Dale Lutz, spoke about the latest release of FME, FME 2012, which has just been released. Safe’s releases of FME are annual, and are designed to always be faster than the previous release and incorporate more file formats than they did before.
What is the most significant feature of the 2012 release, Dale?
The point cloud or lidar support changes that we made in the last year are very significant. W e came out of the gate last year with our lidar support point cloud and I was impressed how well received that was. What we realized was that the volumes of data were even in an order of magnitude greater than what we thought a year ago. We spent the last year really addressing and optimizing for data volume and we’re very please with how the FME 2012 point handling support can gobble up billions of point clouds and put them into Oracle and chop them into little pieces in very timely ways. Don [Murray] has said that every release of FME has to be faster than the previous one and we did meet that with more than ten percent overall across 5,000 tests, we are more than 10% faster. Even if existing users don’t do anything else they just put on the new release they’re going to be getting their jobs done faster than before. In terms of our overall offering, as you know we have FME Server, and there we’re doing a thing we call notification server which has to do with the notification idea – that not only can we centralize data moving on a server, we can now react and cause it to move when an event happens outside. Kinds of events can be, for example – a file arrives in a folder and that’s a stimulus that can cause a response by our server to upload that file into a database or into a Quality Assurance check on that thing. These are event driven actions, as opposed to the user having to poke the server and saying please do this.
One example is a file arriving causing an event – an email arrives and it causes something to happen. A web sensor of some kind posts results – we’ve been doing some demos and playing with web sensors and that data can come in and our server can do something. Now there is a field called complex event processing or CEP and what we really think we’ve got here is spatial complex event processing where an event happens and a transformation process starts. Not only can it move data around but can also take advantage of where that event happened.
So that’s the notification addition into our FME Server product family.
How many of these new features did customers request?
Parts of the new features were requested by people but we generalized their requests into something greater. We know that many of the use cases I mentioned to you are futuristic — they’re ready for the internet of things or the sensor web that people talk about. Practically what people ask for is the first one I mentioned, if the file arrives the folder does something because that’s closer to our traditional space. When I talk about sensor web that flirts with the user space that we’re confident that we’re able to address but we might be ahead of our user base there.
You mentioned more file formats in the new FME 2012.
The world is always creating more formats – I believe the number is 285 now with FME 2012. Existing formats don’t stay still either, they’re always changing and growing. CityGML had a new version this year, GML is looking at another version, there’s always more happening. The development team has to juggle all this and it’s not getting easier each year.
The other half of this is the world of the cloud. Although it’s not a file format, it’s a new place where data can reside. And so in FME another key feature is the fact that we can read and write Google Fusion tables and so there you have a new “format” but it’s not a file, it’s a mystical call out to the cloud. You use FME to put data up there and then you permit it, then instantly the whole universe can share in it. It’s a way of publishing data that can be used by anybody instantly so it’s quite interesting what this opens up for collaboration.
How do you address private clouds, which we hear a lot about these days?
Private clouds are not on the data format side, but rather on the deployment side. People ask can we install your software and get our own private cloud can we install it on an Amazon system? We do have an answer on all those cases. We have many customers already doing cloud based deployment using our software in the cloud, running in the cloud in a variety of ways.
That’s an area that continues to explode. We have moved to using cloud hosted FME for all our training. If you take an FME training class, no matter where you take it, whether it’s online or in person, you’ll be using an FME installation in the cloud. The reason is it’s way easier for us to administer it. But even if you come to our office to do training in our Training Center you’ll be connected to FME in the cloud even though it’s in our own office.
We’re doing a soft launch of what we call the FME Store, which is a way for certain parties who belong to the FME ecosystem that build plug ins or extensions for FME to be able to make the rest of the FME community aware of what they’ve created.
Autodesk and Pitney Bowes pen new partnership
Wednesday, January 18th, 2012For about three years, I have been watching Autodesk do interesting things with their GIS division, finally rolling some great mapping products into their Infrastructure Division. The sense was that Autodesk was primarily a provider of software for the built environment, with its GIS products designed with the architect or engineer in mind.
