getmapdl.lua [options]

 downloads an OpenStreetMap or Google Maps map specified by [options]

 Options:

 -m specify the mode (osm|gm)

 -l  specify a location
     e.g. 'Bergheimer Straße 110A, 69115 Heidelberg, Germany'

 -x  specify a xsize (600)

 -y  specify a ysize (400)

 -S  short form to specify a size, e.g. 600,400 (osm) or 600x400 (gm)

 -s  specify a scale factor in the range 1692-221871572 (osmm) or
     1-2 (osm)

 -z  specify a zoom in the range 1-18 (osm) or 0-21 (17) (gm)

 -t  specify map type {map|sathyb} (map) (osm) or
     {roadmap|satellite|hybrid|terrain} (roadmap) (gm)

 -i  specify image type {png|gif|jpg|jpeg} (png) (osm) or
     {png|png8|png32|gif|jpg|jpg-baseline} (png) (gm)

 -c  specify icon color (yelow_1) (osm) or (blue) (gm)
     see: http://open.mapquestapi.com/staticmap/icons.html
          https://developers.google.com/maps/documentation/staticmaps/#MarkerStyles

 -n  specify the icon number (1)

 -o  specify output basename without file extension (getmap.IMAGETYPE)

 -q  quiet; no output!

 -v  prints version information

 -h  prints help information

 gm mode only:

 -M  specify markers; see:
     https://developers.google.com/maps/documentation/staticmaps/index#Markers
     e.g.: &markers=size:mid|color:blue|label:1|address or more of these
     location and zoom will be ignored if used!

 -C  specify center of the map

 -V  specify a list of visible locations (loc1|loc2)

 -P  specify path from location to location
     e.g.: &path=weight:7|color:purple|loc1|loc2

 gsv mode only:

 -H  specify heading (view) (0) (0 -- 360) (east: 90, ...)

 -T  specify the pitch (angle) (0) (-90 -- 90)

 -F  specify horizontal field of view (90) (0 -- 120)
     The field of view is expressed in degrees and a kind of zoom!
