Hi, this isn't a criticism, just a general reminder to people uploading images about our ongoing struggle to free up every little bit of disk space we can- if running in a VM and the resolution has been stretched the image comes out a bit dithered/out of focus, which has the tendency to make the PNG images four times as big as they otherwise would have been. If the screenshot has a high proportion of imagery check if a 85% quality JPEG makes the filesize much smaller without compromising on clarity. Images already fuzzed/dithered from a stretch will generally look no worse as JPEGs (but try to avoid that happening in the first place :). For remaining PNGs run them through 'optipng -o5' or better crusher, often this can save 30%, losslessly. If not using an alpha channel, drop it back to just RGB from RGBA. > I havn't change the last part with missing strm file. Can SAGA deal with raw .hgt files? How about .hgt.zip without unzipping them first? Those usually are less than 1.5mb per SRTM file so having one of them on the disc would be fine I think. hgt should be more relevant than an ancient Surfer grid anyway. > I'll try to use some pointclouds or dtm from the available data. I don't thing we ship any LAZ or LAS, but there is some lidar data in ~/data/north_carolina/shape/ to play with (elev_lid*.shp). Also in the NC raster dir there are a number of DEMs and satellite imagery to drape over it. thanks, Hamish _______________________________________________ Live-demo mailing list Live-demo@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/live-demo http://live.osgeo.org http://wiki.osgeo.org/wiki/Live_GIS_Disc
