[OSGeo-Discuss] Can I do the same GIS tasks with OS (as with ESRI)?

[RAVI KUMAR]

Hi,
this is the kind of question I face when in my lectures evangelising OS GIS.
ArcGIS has many tools, though some prefer to call it a deluge of tools, which almost distance the user from understanding the concept of GIS.

Auto Complete Polygon: 
In Qgis which is a very userfriendly OS GIS you have 'Cut polygon', do try and find the difference.

Polygonising from lines:
Open JUMP has one of the most userfriendly approaches.
Create lines and polygonise in OpenJUMP and the software automatically 
creates a folder for Dangles (un-wanted line pieces)

The query is more for Vector GIS, I suppose.

GRASS GIS:
It has so many features for Image analysis and Raster GIS, the commercial GIS need a barge pole to even touch it. The vector Part of GRASS is robust too.

We are working on that:
 http://grass.osgeo.org/wiki/WxPython-based_GUI_for_GRASS#Digitizer

Screenshots:

 -> wxPython (new GUI)

You can try out the prototype in GRASS 6.3.0 (released yesterday):
 http://grass.osgeo.org/announces/announce_grass630.html

Get MacOSX, Linux and now even native MS-Windows binaries with *installer* at
 http://grass.osgeo.org/download/index.php#g63x

Enjoy
Markus
