v15 v16 44 44 By default this will do timing runs for each line on the gridengine using SCT offsets between -0.1 and 0.1. 45 45 46 '''dem?'''47 48 To return sensible results you will need a dem. One should have already been completed in the unpacking stage. If not, it will need to be created. If the project is in the UK you can use [wiki:Processing/NextMapDEMs Nextmap data] (try running `nextmapdem.sh` in the project directory to do it automatically, otherwise see the [wiki:Processing/NextMapDEMs wiki page]). If it's non-UK, you'll need to use [wiki:Help/LeicaLidarDems LiDAR data] (you may wish to use this anyway if it's available - see [wiki:Processing/CreateTifs here] on how to do this using a script), or failing that [wiki:Processing/SRTMDEMs SRTM 90m data]. Copy it into the dem directory. Once you've done this include the DEM file in the config file by entering "dem=<dem_file_name>" under the DEFAULT section.49 50 46 Check against OS vectors. 51 47 … … 69 65 1. Check each set of flightlines to work out which has the best timing offset (ie has the straightest roads, etc). Make a note of the timing offset values in the ticket 70 66 1.
