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

Hi Cameron,
the table of comparison is informative.
Most of the ARC-GIS users (my personal view) are Vector GIS users.
They are concerned of
1. Registration of Paper maps into GIS
2. Attribution
3. Analysis depending on their need.


4. Outputs of the above are also to be plotted in elegant maps with proper symbology and standard colors.

As an OSGeo enthusiast I recommend a cocktail of OS GIS software mix.

OpenJUMP and Qgis for steps Qgis 1 to 3
Qgis and GRASS for advanced analysis  
GRASS for statistical analysis with R

OpenJUMP and Inkscape for step 4. As a geologist I get oriented structures properly symbolised and rotated (possible in OpenJUMP)

Am making some notes and soon wish to offer for downloading through GRASS and OpenJUMP websites.

What us Open Source evangelists are missing is an honest comparison 
between ESRI desktop applications and Open Source equivalents.

What is it about ArcView and ArcGIS that people really like, listed 
feature by feature in a table.
Then identify whether Open Source covers it and how.
Very important is to address usability. How quickly can an Arc* user 
migrate to Open Source?
My skill set is lacking here as I don't have much experience in either 
ESRI or the Open Source desktop tools. It seems like you have experience 
with both which puts you in a unique position.

Is this something you, or one of your students would like to investigate 
further? Maybe build a table similar to this one:
