98
100 r.report allows the user to set up a series of report parameters to be
101 applied to a raster map, and creates a report. The report will print
102 out to the standard output if output parameter is not given.
103
104 The report itself consists of two parts, a header section and the main
105 body of the report.
106
107 The header section of the report identifies the raster map(s) (by map
108 name and title), location, mapset, report date, and the region of in‐
109 terest. The area of interest is described in two parts: the user’s cur‐
110 rent geographic region is presented, and the mask is presented (if any
111 is used).
112
113 The main body of the report consists of from one to three tables which
114 present the statistics for each category and the totals for each unit
115 column. Note that the statistics is always computed in the current geo‐
116 graphical region.
117
118 When multiple (typically two) raster maps are specified, cross-tabula‐
119 tion table for each combination of categories in the raster maps will
120 be computed and formatted in a human-readable way (see example).
121
123 Note that, unlike r.stats, r.report allows the user to select the spe‐
124 cific units of measure in which statistics will be reported. To output
125 computer-friendly data suitable for importing into a spreadsheet use
126 the r.stats module. In fact r.report is running r.stats in the back‐
127 ground and reformatting the results to be more human-friendly.
128
130 Report sorted areas in square miles and acres for each category.
131 No-data are not reported (see -n flag).
