Tutorial for the GUI-version (a had to try the windows version 😦

vector-layer – schools
athens drive high school,-78.710796,17z

import data

for the nc-test-dataset a simple ascii-data-import
create a text-file with this data

then import the data with this command –overwrite input=D:\boehs\grassdata\nc_basic_spm\gisdemo_ncspm\user1\testdata.txt cat=1 x=2 y=3 out=startend col=“cat integer, east double precision, north double precision, label varchar(6)“

now you can add the vector layer startend to your map and zoom to the new points

test wms/wmts

here i get an answer -l mapserver= output=wmts mapserver= srs=EPSG:3857 format=geotiff maxcols=1024 maxrows=1024 folder=d:\ method=nearest mapserver= srs=3857 driver=WMTS_GRASS
