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

[Randy George]

I know this is not OS but GoogleChart is easy to use:

http://chart.apis.google.com/chart?cht=p3&chd=t:20,40,30,10&chs=250x100&chl=
Hello|World|of|Google

and it can be used to add chart icons for use in online mapping interfaces,
not necessarily Google's, and not just pie charts. However, as with all of
Google stuff the license is a gotcha for most businesses.

Adding your own similar chart tool using svg or wpf/Silverlight interfaces
would not be much of a problem. Plus you get better scaling with vector
graphics along with click/rollover/tooltip... capabilities. 

Raster Icon charts seem to be a useable approach for map data as discussed
here:

I'd favor vector if you want drill-in capability though.

Concerning OpenJump it is really good but I couldn't make a pie chart map
with it as I could do with Arcview 3.x 
I added the charts plugin but I think It doesn't classify the size of charts
symbol. 
Does anyone can do it by any open-source GIS?

A convert! Welcome Jennifer.

I can't speak for GRASS, but I know that OpenJUMP
(http://jump-pilot.sourceforge.net/OpenJUMP.html) could be compared to
the old 3.X Arcview. It has limited printing abilities at this point in
time, but I don't think there is a better cross-platform tool for basic
ESRI Shapefile manipulation. (I'm a volunteer on the project and
therefore biased in my opinion on this matter.)

I think you will find you can do 95% of what you could with ESRI
software, you'll just have to do it with an assortment of tools instead
of a single tool.

The thread that was started today with the subject "Your open source 
career" got me thinking about asking a question that has been rolling 
around in my head. This is pointed at those people who have experience 
with ESRI products as well as OS GIS products.

I have been a long-time user of ESRI products, but I want to start my 
own contract business and will not be able to afford the license for 
ArcGIS/ArcInfo. So I recently set up a Linux box with GRASS installed, 
but it has been over 10 years since I have used GRASS (it has probably 
changed since then too!)

Does GRASS have the same analysis and display capabilities as ArcGIS? I 
know this is a very general question, so perhaps another question would 
be where does GRASS fall short and where does it excel in comparison to 
the ESRI products?

Thanks,
Jennifer
