| Book Page(s) | Module | Correction |
| p. 23 | NSF | NFS (network file system) |
| p. 29, 36 | tar | tar -xvzf should be tar xvfz , same for cvfz |
| p. 46, 47 | cs2cs | – an extended list of projections is generated with ‘cs2cs -lP’- 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. 60 | g.region | also the raster map needs to be specified: g.region rast=elevation res=30 -p |
| p. 61 | g.region | also the -a flag must be used to align: g.region rast=ortho_2001_t792_1m res=10 -ap |
| 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. 85 | r.colors | The numeric value related to the color was missing for “brown”. Additionally, from GRASS 6.4 onwards, the RGB triplets have to be separated by colons (255 255 0 -> 255:255:0):> 0% aqua > 20% green > 100 255:255:0 #yellow > 120 orange > 157 brown > end |
| 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. 235 | r.surf.nnbathy | Statement: “It uses ‘nn’ … allows the user to define breaklines…” is not possible since r.surf.nnbathy accepts only a single raster map as input. |
| 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. 354 | install.packages() | The command is incomplete: # non-Mac users install.packages(c("spgrass6", "gstat"), dependencies = TRUE)# Mac users install.packages(c(“spgrass6”, “gstat”), type=”source”, dependencies = TRUE) |
| 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 |
