Underground GIS

Yesterday I heard about an interesting Munich project called Artchalking
which is a grassroots project to map wifi hotspots in Munich. This is a technology I as yet know little of but find it interesting and very "democratic" in nature. My interest in GIS has been rekindled by the website Mapping Hacks
a fascinating site which I cannot recommend highly enough. Short post today as we have childcare to return to!

Eureka!

Somehow my prayers have been answered! Today in the new http://grass.itc.it/newsletter/GRASSNews_vol3.pdf GRASS Newsletter the exact solution to my question was presented in the form of two papers from Italy and New Zealand! The question was how to use SRTM and VMAP in tandem in GRASS to process the downloaded data.

Markus Neteler and M. Hamish Bowman wrote two wonderful papers which guide the way on the subject in hand. They seem as excited about the SRTM/VMAP recent move into the public domain as I am.

Meanwhile over in Blighty, the http://www.systemed.net/blog/entry041216225441.html New Popular Maps of Britain have been released. Given that free mappers only need often B Roads and paths which haven't changed much in a long time I am sure this is a revolutionary move.

Remake of south Bavaria

Ran through the GRASS commands to rebuild south Bavaria.

It is not exactly IKONOS but hell years ago this imagery used to cost thousands.
