*Book Page(s)*	*Module*	*Correction*
p. 29, 36	tar	`tar -xvzf` should be `tar xvfz` , same for `cvfz`
p. 46, 47	cs2cs	last line on p. 46 should say: see EPSG code 2163, epsg:3358 is for the initial coord. system NC State Plane
p. 47	nc_stm location	The correct name is 'mync_spm' and it is created on page 37 (Section 3.2)
p. 49, bottom	gdalwarp	To maintain the resolution, it is recommended to use '-tr xres yres': gdalwarp -t_srs "`g.proj -wf`" -tr 28.5 28.5 -te $w $s $e $n \ p016r035_7t20020524_z17_nn30.tif \ p016r035_7t20020524_nc_spm_wake_nn30.tif
p. 77	g.region, d.rast	`IMG_airBW_79200WC_3ft` does not exist, the correct name of the raster map is `ortho_2001_t792_1m`
p. 81	v.out.ogr	v.out.ogr soils soils --> v.out.ogr soils_general v.out.ogr schools --> v.out.ogr schools_wake v.out.ogr roads --> v.out.ogr roads_major
p. 81	v.out.ogr	facility_3d is missing in the mapset, see errata for v.extrude below how to create it from the vector map facility
p. 81	v.out.ascii	v.out.ascii schools --> v.out.ascii schools_wake
p. 106	r.mapcalc	rand(low,high): generates random numbers between low <= x < high
p. 131, 3rd line from page bottom	r.regression.line	'medians (medX, medY)' should read 'means (medX, medY)'
p. 210	v.extrude	v.extrude requires polygons as input to extrude to 3D house blocks: v.extract P079215 out=bldg_resid where="layer='BLDG_RESID_BL'" v.extract P079215 out=bldg_cmcl where="layer='BLDG_COMMER_BL'" # add these new commands: v.type bldg_resid out=bldg_resid_bnd type=line,boundary v.centroids bldg_resid_bnd out=bldg_resid_pol v.type bldg_cmcl out=bldg_cmcl_bnd type=line,boundary v.centroids bldg_cmcl_bnd out=bldg_cmcl_pol # add height of the building (use new input maps) v.extrude -t bldg_resid_pol out=bldg_resid_3d height=10 \ elev=el_D792_6m v.extrude -t bldg_cmcl_pol out=bldg_cmcl_3d height=15 \ elev=el_D792_6m
p. 257	nviz	The correct input raster maps need to be defined: `nviz lidar_dsm,lidar_dtm col=ortho_2001_t792_1m,ortho_2001_t792_1m`
p. 362	writeRAST6()	The wrong map is written out if 'zcol' is not specified: `writeRAST6(annual_precip, "var1.pe", zcol=3)`
p. 376	Eq. A.58	index x-1 should be i-1
p. 401/Index	r.param.scale	The module name is missing from the Index, it is discussed on p. 149/150
