[Qgis-developer] fTools and GdalTools: sextante vs original plugins

[Bernhard Ströbl]

Hi all,

for a course I am about to give tomorrow I played a bit with SEXTANTE, 
although I am going to teach geoprocessing with fTools (we are using 
QGIS 1.8). It was my first go with SEXTANTE and I was about to show what 
it will offer in the future. Therefore I built a small model with three 
input layers a buffer and two overlay operations. I did not succeed in 
running the model so I tried in current master.
As it currently is SEXTANTE is not operable for me (or I am doing it 
wrong): First message is "Layers do not all use the same CRS...." 
although they definitely do and the same EPSG-code is noted in square 
brackets behind each layer name!? Second I get an "Error executing 
algorithm..." it seems as SEXTANTE cannot use PostGIS layers as input 
(when I save them as shape files the model runs perfectly), this is a 
big limitation as my institution stores almost everything in PostGIS. 
(SEXTANTE should not offer PostGIS layers to choose as input layers then).

Well, this was a very disappointing experience because additionally QGIS 
was frozen two or three times opening or closing the model. I do not 
want to complain, all I want is to ask for keeping fTools as they are 
until SEXTANTE can _really_ replace them in all aspects. Then we should 
remove the vector menue completely because I agree that finding the tool 
you are looking for is a lot easier in SEXTANTE.

my 2 cents

Bernhard
