Hi, I have to convert the vector(point) data into raster, I imported point data into the GRASS and then used v.to.rast command to convert vector to raster map, but the same problem: nothing is displayed on the display, and query data is giving a value of zero in the map display. If it is a problem with projection and region, please help me to resolve this. the point data's metadata is : Name: RGP_Before_2014_Wagner_s_80_E_of_Hwy_80_E_of_HWY_20_2013_ | | Mapset: battu | | Location: RedRiverValley | | Database: /home/shared/research/GRASSDATA | | Title: | | Map scale: 1:1 | | Name of creator: battu | | Organization: | | Source date: Mon Dec 15 16:18:26 2014 | | Timestamp (first layer): none | |----------------------------------------------------------------------------| | Map format: native | |----------------------------------------------------------------------------| | Type of map: vector (level: 2) | | | | Number of points: 10182 Number of centroids: 0 | | Number of lines: 0 Number of boundaries: 0 | | Number of areas: 0 Number of islands: 0 | | | | Map is 3D: No | | Number of dblinks: 1 | | | | Projection: UTM (zone 14) | | | | N: 46.98666723 S: 46.97957943 | | E: -98.65789266 W: -98.66294363 | | | | Digitization threshold: 0 | | Comment: | | and g.proj -p gives me the following:
-PROJ_INFO------------------------------------------------- name : Universal Transverse Mercator proj : utm datum : wgs84 ellps : wgs84 zone : 14 no_defs : defined -PROJ_UNITS------------------------------------------------ unit : metre units : metres meters : 1 Could please anyone help me solve this issue. I need to generate raster maps from given vector(point) data.
