The NRCS’s Web Soil Survey has finally gone live. I have seen it since its alpha, and it is a good substitution to the hard copy soil reports. The WSS is built on ArcServer and ArcSDE technologies and will continue to grow. Take a look to see what they have implemented and I will try to remember to blog any big changes.
Always new ways to use aerial imagery.
OK, it is late I probably shouldn’t blog just before sleep, but I figured I would forget this link in the morning. The Digg submission linked below is a person who found clouds on the aerial imagery when they were on Google Maps. They don’t say whether they think this is good or bad, but being sleepy I am going to assume they were incredulous at the least. My problem with this? One contracts for US government agencies the company flying the data is required to have the images be 85-90% cloud free for an acceptable product…satellite imagery, you hope for 60-70% cloud free if you are looking for something in a certain time range (if you aren’t picky about when it is usually easier to find cloud free data). So a couple of clouds in a commercial product that has little to no orthorectification (though pretty good georectification) isn’t something I would find note worthy.
Well that isn’t true, it gave me a chance to share you lovely people why a cloud isn’t a big deal.
So follow the link to see the cloud (it is quite a nice cloud in fact). Clouds on Google Maps
Continuing my obsession is an article regarding NASA’s new instrument for capturing the martian surface. Please not that they talk about the number of pixels the instrument will collect at a time, but not what the spatial resolution of each pixel will be, which is actually more important for the end-user. The other important information, that could help us determine the spatial resolution of the imagery, is anticipated scale.
Here is a link to an undated article on Geoplace.com that gives a short summary of the Shuttle Radar Topography Mission that flew on the Space Shuttle Endeavor in February 2000. The data processing has been completed, and the data is now available.
This is a feature article from Geoplace on the use of GIS and other geospatial technologies to help with conservation efforts to save mountain gorilla habitat in Africa
Continuing my obsession with extra terrestrial use of geospatial technologies, here is a quick article on Lidar for use on Mars National Post
