New global 30 m Landcover data set released

China has released a new global 30 m resolution landcover data set for ca 2010. From the first glimpse looks better than Globcover, even CIMMYT’s research station in Sonora is properly classified as artificial surface and towns that were absent in Globcover. User registration and login work well but still waiting for the download links for the the actual tiles.

Hope enough of you can try this out so we can see if its worth using broadly but seems promising.

GIS based analysis on impact of climate change on maize bean systems in Central America done by CSI members:

Higher temperatures and changes in rainfall patterns could transform the agricultural landscape of Central America, threatening the livelihoods of one million maize and bean farmers, according to a pioneering report released today that for the first time takes a specific look at the impact of climate change on a local level.

Joint development of a GRASS 7 course (manual, tutorial) for NARS etc?

Hello fellow agricultural geographers, geographical agronomists, modelers, crime scene investigators, etc,

As it seems that GRASS is finally running satisfyingly under Windows, something I’ve wanted to do for a couple of years but didn’t want to get into due to the need to have Linux running to fully use the potential of GRASS now seems finally possible. The idea would be to use GRASS 7 and future versions for our training efforts with NARS and other collaborators that can’t afford to use ESRI products. In our training courses here with scientists and technicians from all over the world interest in GIS is always very high. We have been using free alternatives like DIVA, GEODA and GVSIG, which work quite well for some things but don’t cover all needed functions and it would be better to have everything under one platform. GRASS on the other hand is basically capable of everything that ARCGIS can do with maybe a steeper learning curve and not as user friendly. It would give us the opportunity to properly train people and give them a free powerful tool to incorporate GIS in daily work in institutions. Having said that would it make sense to the CSI community to do this as a joint effort and maybe a product towards our annual meeting? CIMMYT eg would look at modules, functions and data sets relevant to breeders, conservation agric in English and Spanish.

Let me know what you think?

Cheers,
Kai
