I just saw this article on Geocommunity. Apparently , a private company called Mapflow is teaming up with the Dublin Transportation Office (Ireland) to do a feasibility study on the use of satellite technology to track cars in real-time, and then charge drivers for the distance they travelled on the toll road. The study is also being funded by the European Space Agency. Yeah……. I think I will leave it at that, and let you read the article
Geosoft has added Shuttle Radar Topography Mission (SRTM) data to its public server. Elevation data for basically the whole world is available at 90 meter resolution and the US at 30 meter resolution. I checked out the site, and the data is in the public domain and free to download.
Here is the link to their data server
Here is a cool UK website that details a project that “aims to collect a geographically representative photograph for every square kilometre of the British Isles” They bill it as a geography project for the people, since the photos are submitted, and apparently already have 30,000 grid squares covered.
Extraterrestrial mapping efforts continue
The future of Hubble may seem similar to that of Landsat 7, but it is still getting the job done. Archives are nice too…
First Australia, then Korea, now the Dutch. However, for the first time I see someone has mentioned the USGS’s National Map. While the National Map focuses on the US and does not have the smooth interface that AJAX offers yet…it does offer better overall imagery throughout the US.
This article from GeoCommunity’s Spatial News will tell you….
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.
