EXPLANATION

location

This record gives the GRASS database location.
location <name> <full name>

<name>

database location

<full name>

long name for the location

mapset

This record gives the GRASS mapset.
mapset <mapset>

<mapset>

mapset under which the report was run

region

The region records give the mapset region coordinates.

region north <N>
region south <S>
region west <W>
region east <E>

<N>

north for current region (float)

<S>

south for current region (float)

<W>

west for current region (float)

<E>

east for current region (float)

resolution

This record gives the GRASS database resolution in meters.
resolution <res>

<res>

resolution of the database, in meters (float)

point

These records describe the sites that were used in the report. There is one 'point' record for each site.
point <site_ref> <E> <N> <desc>

<site_ref>

a reference number, used by other lines in the report to reference this site

<E>

site easting

<N>

site northing

<desc>

a description of the site (usually an site number)

layer

These records describe the map layers that were used in the report. There is one 'layer' record for each layer.
layer <layer_ref> <name> <full_name>

<layer_ref>

a reference number, used by other lines in the report to reference this layer

<name>

name of the map layer (raster file name)

<full name>

full name (TITLE of raster file)

cat

These records give information about each category in each layer.
cat <layer_ref> <cat> <count> <name>

<layer_ref>

reference number of the layer

<cat>

category number

<count>

number of times this category occurred

<name>

full name of the category

matrix size

This record gives the number of cells in each site.
matrix size <matrix size>

<matrix size>

number of cells per site.

matrix

These records describe the locations of each cell in the site relative to the center of the site.
matrix <ew_disp> <ns_disp> ...

<ew_disp>

east-west displacement from the site

<ns_disp>

north-south displacement from the site

The displacements are in units of 1 cell, which is equal to the resolution of the database. They are paired, and there will be <matrix size> pairs. To compute the coordinates for the cell:

north = site_north - <ns_disp> * resolution
east = site_east + <ew_disp> * resolution

data

This is the site data. There is one 'data' record for each site for each layer. The <cat> field is repeated <matrix size> times.
data <layer_ref> <site_ref> <cat> ...

<layer_ref>

reference number of the layer

<site_ref>

reference number of the site

<cat>

category which occurred
