The LiDAR source location has x- and y-resolution of 3 feet (international) and several thousand cells east-west and north-south. g.region -p for this location displays:
projection: 99 (unnamed) zone: 0 datum: ** unknown (default: WGS84) ** ellipsoid: grs80 north: 1286590.24500872 south: 1240510.24500872 west: 634966.76150938 east: 664972.76150938 nsres: 3 ewres: 3 rows: 15360 cols: 10002 cells: 153630720 When in the project location g.region -p produces: projection: 99 (NAD_1983_HARN_StatePlane_Oregon_North_FIPS_3601_Feet_Intl) zone: 0 datum: nad83harn ellipsoid: grs80 north: 588219.90693215 south: 536993.58817534 west: 7524575.13218961 east: 7561596.20977101 nsres: 2561.31593784 ewres: 1851.05387907 rows: 20 cols: 20 cells: 400 I want to understand why the nsres is now 2561+ feet, the ewres now 1851+ feet, and the numbers of rows and columns has decreased so drastically. Looking forward to learning, Rich _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
