Hi Agustin, You should really work with some referent point for which you know both local and geographic (WGS84) coordinates. Here is an illustration: http://spatial-analyst.net/wiki/index.php?title=MGI_/_Balkans_coordinate_systems#Validation_of_CRS_p arameters Note that I use Google Earth

[R-sig-Geo] getting subfolders in a directory on FTP (MODIS)

Good morning, I know this is not exactly a question for R SIG GEO, but as it may interest beginners like me who work with MODIS data... (and I'm hoping I'm not the only beginner on the list !) I adapted the script of Tomislav Hengl (again thank you for your wiki page!

[R-sig-Geo] split SpatialPolygon after unionSpatialPolygons()

I've used unionSpatialPolygons to dissolve polygons and get a grid as a spatialpolygon. A simple example: grelha-readGDAL(paste(C:/...,teste.bmp,sep=)) grd - slot(grelha, grid) pol - as.SpatialPolygons.GridTopology(grd) pol - unionSpatialPolygons(pol, SGDF2PCT(grelha)$idx) When the original
