[Qgis-user] Conditional statements

2011-07-07 Thread Carlos Andres Rios Franco 
Hi Guys

Someone knows how to do Conditional statements in GDAL Tool's Raster
Calculator?

For Example:
In ArcGIS: CON(([RASTER]  500), 300, 100)   or
   CON(([RASTER]  500), 300, CON(([RASTER] 
250), 150, SetNull([RASTER])))
In Excel: IF(([VALUE]  500), 300, 100)

Hi Julio César

Try this:

   - Vector (menu)
   - Data Management tools
   - Join attributes by location
   - Target vector layer: your poins layer
   - Join vector layer: your shapefile of vegetation

It will works!

good luck!

 Hello there,

 I have a points layer with the locations of several bird species, I have a
 shape file with the attributes of vegetation in my study area. I want to
 create a table using these two layers to know about the presence of the
 species on the different vegetation types, so I want to get something like:
 species, lat, lon,vegetation.
 Is this possible with Qgis (1.6)? If yes, could somebody tell me how to do
 it?

 Thanks a lot in advance.
