[GRASS-dev] v.class and d.thematic.area in svn

[Moritz Lennert]

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)
