The satellite data I'm working on is comparable low-res (150m/pixel) and only updated once a year (if ever). Main reason for updating the tiles is that I'm still experimenting with thing like PNG quantization and compression options. What could become interesting in near term is the European Global Monitoring for Environment and Security (GMES) satellite project. Which despite having the name security in it is supposed to have an Open Data Policy [1]. European institutions tend to have a strange implementations of "Open Data Policies", but continuous and free access to multi spectral satellite data with 10m/pixel resolution could keep us pretty busy. cu andreas [1] http://www.spacenews.com/civil/100630-officials-open-data-policy-gmes.html _______________________________________________ Maps-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/maps-l
