Hello. I have some trouble in using v.to.rast. Could anyone help me, please?
I imported ascii vector data (position data) using v.in.ascii, then converted it into raster data using v.to.rast as follows; v.in.ascii input=test.txt output=test x=2 y=1 z=3 columns='x double precision, y double precision, z double precision' -z v.to.rast input=test output=test0 use=z I succeeded to import ascii vector data by v.in.ascii. However, when I comverted vector to raster, the position of raster data was not in the right place. A little moved. If I displayed both vector data and comverted raster data, the vector position data was not shown within the corresponding pixel of raster. How can I solve this problem? Information about my setting is as follows. projection: 3 (Latitude-Longitude) zone: 0 datum: wgs84 ellipsoid: wgs84 north: 29:00:16.07148N south: 4:59:43.928556N west: 91:59:43.92852E east: 110:00:16.0704E nsres: 0:00:32.142857 ewres: 0:00:32.142857 rows: 2689 cols: 2017 cells: 5423713 A part of imported ascii vector data: 19.3|97.83333333|1.1111 18.16666667|97.93333333|2.1111 19.91666667|99.83333333|3.1111 19.13333333|99.9|4.1111 18.78333333|98.98333333|5.1111 (latitude | longitude | data) I hope someones's kind help. I wish you all happy new year!
