Really, what CAN’T geospatial do? Researchers out of University of Padua in Italy took aerial photos of an area just north of Venice and discovered what used to be Altinum, a thriving city that existed before Venice. The site is fairly unique in that it’s one of the few places that haven’t been built upon by later generations, thus making it ripe for study. The team intends to continue their work using LiDAR and other techniques to help archeologists figure out the best places to continue their work excavating this important site.
The RSPSoc – Remote Sensing & Photogrammetry Society is a UK-based academic association that looks at the application to education, science, research, industry, commerce and the public service of RS and aerial imagery. The RSPSoc maintains a significant number of activities and publications. The upcoming RSPSoc 2009 conference will be taking place in Leicester on September 8-11. Publications from the association include the International Journal of Remote Sensing (IJRS), the The Photogrammetric Record (PHOR), a newsletter, and proceedings from the annual conference. The RSPSoc website has a wealth of information including an educational area, public outreach, student community, and special interest groups.
That’s right, it was March 1st, 1984 when Landsat 5 lifted off on a expected 3-year Earth observation mission, and here we are 25 years later, and the old workhorse is still capturing imagery! So, congrats to NASA and Landsat 5 on a quarter century of documenting Earth from space!
You can read the NASA press release on the 25th anniversary of Landsat 5 here, with some interesting tidbits on some of the satellite’s issues over the years and how they’ve kept it orbiting and still capturing imagery.
BBC news has an interesting article on the mapping of the Gamburtsevs which lie under the ice in Antarctica. The article describes the use of radar, magnetic, and sonic/seismic remote sensing methods by a group of scientists, engineers, pilots and support staff from the UK, the US, Germany, Australia, China and Japan. Definitely an interesting read. Head over to check it out.
The CrunchGear blog has a post regarding Boston College’s use of Lidar for mapping rivers and streams for fish repopulation. Nothing ground breaking technologically but it was interesting to see a mainstream tech blog talking about what we consider a mainstream technology.
I was just checking my Twitter feed, and I had to check out a tweet from NASA about their interactive page called Eyes on the Earth, which is a cool gateway to information about all of NASA’s Earth Observation missions, like ICEsat, Cloudsat, Landsat 7 and even the new OCO (Orbiting Carbon Observatory) that is scheduled for launch later this month.
Oddly, though, Landsat 5 is not shown on the Eyes on the Earth graphic. I know Landsat 5 was experiencing some age-related issues, but the word I remember from back in February 2008 was that it was back in action. Hmmm, maybe I missed a press release or news item somewhere…
The BBC has an interesting article on plans by Surrey Satellite Technology Limited (SSTL) to launch a $70million satellite that will be able to capture 60cm pixel images. SSTL believes the proposed satellite system dubbed ART (Accuracy, Reach, Timeless) could cover 95% of the planet every 30 months. The key to the system is that they anticipate the cost of the imagery to be $0.15 sq/km versus current prices aroung $20 sq/km. Check out the full article over on the BBC website
There have been several companies moving to the webinar route over the last year. These are great ways for users to get to know the nooks and crannies of products, geospatial or not, and it allows for some level of interaction with the person leading the webinar. The downside is that they aren’t always convenient to fit in your schedule, no matter how many times a given webinar is offered. Perhaps the most useful thing about a webinar is that it can be tossed online afterward for any and all who missed the original or just missed a point. ERDAS has gotten around to archiving their webinars for the general public. What is more, they seem to be rolling them out quickly so you don’t have to wait a month or more if you missed the live webinar. And…AND…you can take it with you when you download the webinar and run it on your laptop though you will need the WebEx ARF player to view the file, so no viewing on your personal media player of choice.
We received an email from long time VerySpatial friend Michelle about the release of the full library of Landsat data. We touched on the fact that Landsat 7 was freely available a while back, however you can now access the full 35+ years of Landsat 1 through 7. To access this data head over to the USGS Global Visualization Viewer (GloVis) or the EarthExplorer. If nothing else, the USGS just made remote sensing class projects so much easier.
Earlier this week another US agency, the Census Bureau, posted the 2008 TIGER/Line Shapefiles for road networks and addresses. This is a very large dataset that is broken into many pieces, but I haven’t had a chance to play with it yet. For the most part the data is generally used is small areas where only one or two pieces are needed. However, some folks may need to have access to larger areas, so if anyone goes through the process of joining the data or creating a web service of the data let us know so we can point everyone to it.
Scientists have figured out how to predict cholera outbreaks by looking at sea life. The idea pioneered at the University of Maryland is a rise in sea temperatures lead to the production of Phytoplankton, which are the root cause of cholera. As these phytoplankton get into the water supply, cholera pathogens are released and can lead to outbreaks. Obviously fore warned is fore armed, so this is will certainly help public health officials cope with these devastating outbreaks.
