Command line conversions

Command line conversions and output creation

Option	Command line, mandatory parameters	Optional parameters	Notes
DEM to GeoJSON-G	?act=dem2json&in=c:\mapdata\glacier.dem		Output in same directory, with new extension .JSON
LAS to GeoJSON-P	?act=las2json&in=c:\mapdata\little.las		Output in same directory, with two new files with new extensions .JSON and .JSON.BZ2 7zip used for compression
Create fabric overlay	?act=terr_farbric&in=c:\mapdata\dem.tif&out=c:\mapdata\fabric.dbf	&boxsize=100 (region size) &ptsep=100 (point separation)	If not specified, optional parameters use values in the MICRODEM.INI file.
Create slope map	?act=slopemap+in=c:\temp\test.tif+out=c:\temp\test_slope.tif
Create Openness maps	?act=openmap+in=c:\temp\cop.tif+upname=c:\temp\test_up_open.tif+downname=c:\temp\test_downup_open.tif+rad=250	+rad=250 (radius size of box in meters)	Can do downward or upward openness; give the output names must for those desired.
Create subsampled DEM by averaging	?act=resampavg+in=c:\temp\test25.dem+out=c:\temp\test_resamp.tif	&proj=geo/utm/wkt (wkt has limited options) &dx=1 (meters or arc seconds) &dy=1 (meters or arc seconds) &holes=0/1/2 (0, no hole filling; larger values the radius to fill) &pixelis=area/point	If not specified, optional parameters use values in the MICRODEM.INI file. DEMIX resample by aggregation automates this by creating all the reference DEMs for the DEMIX work.
Create slope uncertainty map	?act=slopeuncertain+in=c:\temp\test.tif		Experimental: Creates output files (3 slopes, 4 directional derivatives, 2 aspects, and a slope uncertainty map in the same directory as the input DEM) Based on a paper under review Same grids created in the GUI under Raster GIS, Create derivative grid, Slope error estimator ?act=slopeuncertain+in=c:\temp\cop.dem+x=601+y=401 will output the intermediate results in the debub log
DEMIX criteria evaluation	?act=demix-criteria&filelist=c:\microdem\demix_criteria_files.txt		filelist is the full path to an ASCII file, with one full path DBF control file name per test DEM requires that the test and 1" reference DEMs be on the local machine, and indexed in the Map library
DEMIX resample by aggregation	?act=DEMIX-CREATE-REF&filelist=c:\microdem\demix_resample_files.txt		filelist is the full path to an ASCII file, with one full path DEM file name per test DEM. This creates 1" pixel-is-area and pixel-is-point reference DEMS, and additional resolutions for high latitude COP and ALOS output will be in the same directory, with standard names

Notes

Start from a command line, type the program name, a space, and the command line parameters:
- microdem ?act=slopeuncertain+in=c:\temp\test.tif
- c:\microdem\microdem ?act=slopeuncertain+in=c:\temp\test.tif
If not specified, optional parameters use values in the MICRODEM.INI file. When the program closes cleanly, the defaults currently set are saved to the INI file. Set the values in the GUI
You can also include in a batch file
The astute will notice that the command lines mirror the format for passing parameters to a CGI program running over the web
Parameter list starts with "?"
Parameters separated with "&" (or "+" if using a batch file, because that environment does not like "&")
Parameter order is not important
Case is not important; the program will convert all to upper case before processing
Supply full names of files, which should not have spaces; there is an in= and out=
Input can be any grid format supported by MICRODEM, but more esoteric ones may require GDAL to be correctly configured so MICRODEM can find it.
