Hi Wolfgang, list,<br><br>geometries2points should be located at "tools for vector layers".<br>Unfortunately I do not know how to figure out which Sextante version I am using. It is the one with 241 algorithms.<br>
I just checked this function with one plain polygon and it worked properly delivering all vertices as points. Nice, I should use this more often ;-)<br>Maybe dealing with multi-part features is not implemented?<br><br>Best,<br>

Hi Johannes,<br>
I did not even _find_ the function geometries to points - ...<br>

Hi all,<br>
<br>
I tried to use /geometries to points/ but Sextante won't accept my multipoint layer which I created in gvSIG.<br>
While Antonio was answering I found the follwing "not so complicated" workaround:<br>
-export multipoint shp to PostGIS<br>
-use this SQL-Statment:<br>
"SELECT ST_X(geom) As x, ST_Y(geom) as y<br>
FROM (SELECT (ST_Dump(mpt.the_geom)).geom<br>
FROM multipointtest mpt)AS mpt;"<br>
this will explode the multipoints into points (function ST_Dump) and create the coordinates columns (functions ST_X and ST_Y)<br>
-Export the results as csv<br>
-Add csv as Event Layer in gvSIG<br>
- be happy ;-)<br>
see screenshot<br>
<br>
Best,<br>
Johannes<br>
<br>
PS: I still use 1.1.2<br>

Hi all,<br>
you can try with "Geometries to Points" tool of Sextante.<br>
<br>
