Hello,
Today I have committed two new modules to svn: v.class and
d.thematic.area, so that others can test and improve. v.class uses the
new arraystats library I also committed. The modules are not compiled by
default.
$ v.class help
Description:
Classifies attribute data, e.g. for thematic mapping
Keywords:
vector, statistics
Utilisation:
v.class [-g] map=name [layer=value] column=string [where=sql_query]
algorithm=string nbclasses=value [--verbose] [--quiet]
Drapeaux:
-g Print only class breaks (without min and max)
--v Verbose module output
--q Quiet module output
Paramètres:
map Name of input vector map
layer Numéro de la couche
A single vector map can be connected to multiple
database tables. This number determines which table to use.
par défaut: 1
column Column name or expression
where WHERE conditions of SQL statement without 'where' keyword
Example: income < 1000 and inhab >= 10000
algorithm Algorithm to use for classification
options: int,std,qua,equ,dis
int: simple intervals
std: standard deviations
qua: quantiles
equ: equiprobable (normal distribution)
dis: discontinuities
nbclasses Number of classes to define
$ d.thematic.area help
Description:
Displays a thematic vector area map in the activeframe on the graphics
monitor.
Keywords:
display
Utilisation:
d.thematic.area [-lnx] map=name column=string
breaks=string[,string,...] colors=string[,string,...] [layer=value]
[where=sql_query] [bwidth=value] [bcolor=string] [render=string]
[--verbose] [--quiet]
Drapeaux:
-l Create legend information and send to stdout
-n Do not draw map, only output the legend
-x Ne pas ajouter la liste des vecteurs dans le moniteur (cela ne
sera pas afficher sile moniteur est rafraîchi
--v Verbose module output
--q Quiet module output
Paramètres:
map Name of input vector map
column Data to be classified: column name or expression
breaks Class breaks, without minimum and maximum
colors Colors (one more than class breaks).
layer Numéro de la couche
Code de couche. Si fixé à -1, toutes les couches sont
affichées.
par défaut: 1
where WHERE conditions of SQL statement without 'where' keyword
Example: income < 1000 and inhab >= 10000
bwidth Boundary width
par défaut: 0
bcolor Boundary color
par défaut: black
render Rendering method for filled polygons
options: g,r,d,c,l
par défaut: l
g: use the libgis render functions (features: clipping)
r: use the raster graphics library functions (features:
polylines)
d: use the display library basic functions (features:
polylines)
c: use the display library clipping functions (features:
clipping)
l: use the display library culling functions (features:
culling, polylines)
