Very interesting. Another signal that geo must integrate seamlessly with mainstream IT to avoid marginalization.

Wired has a big article on the iPad in the April 2010 issue. It even includes a quote from Jack Dangermond. That makes me happy because the geospatial business is mainstream enough to attract Wired’s attention, and hopeful that the iPad may see hardcore mapping apps from ESRI.

I was excited to see this. I think Pipes and YQL are some of the most exciting mashup technologies out there right now, so it’s heartening to see Yahoo! hiring for this team in the midst of all the turmoil there.

Bjørn Sandvik does a great job explaining why the usual ways of projecting KML data don’t work well for world maps. For example, often “Greenland looks like the same size of South America, while it is actually 8 times smaller.” Specifying coordinate reference systems (CRS) in KML was one issue OGC struggles with when considering new features for KML. Do you think one should be able to at least “hint” at what CRS should be used for a particular KML file?

Interesting Amazon “geo-cloud” news via O’Reilly Radar. The skinny is that you can use TIGER shapefiles on a virtual hard drive, IF you buy Amazon EC2 services. This could be a great business model showing how free data can promote the use of pay services.

Last week at Ignite Where Eric Gundersen of Development Seed made a significant announcement for geohackers looking for easy access to open geodata. Amazon will be hosting a copy of TIGER data on EC2 as an EBS (Elastic Block Storage).

This means that you can now load all of this data directly onto one of Amazon’s virtual machines, use the power of the cloud to work with these large data sets, generate output that you can then save on Amazon’s storage, and even use Amazon’s cloud to distribute what you make.
