[udig-devel] Fwd: Re: Mapping the output of an ecological model with uDig 
Hello,
below you find a conversation I had with Jody Garnett. He adviced me to get help from the devel list. Please, take a moment to review what my issues are. The file "OUT00003.txt" contains a sample model output. The file Gutierrez-"BiologControl_2005.pdf" shows what kind of map I would like to get by reading an output file. 

Regards,

Luigi

Thanks Jody,
When you refer to people I will meet in the list, do you mean I should subscribe to the "udig-devel" mailing list? Should I forward the message I sent you to that list? Is that the place to look for the tools that you said are already available and could perform some of the kind of operations I need? 
Yes - I meant the devel list.
Thank for your suggestion. I attach an excerpt from a paper by the lab I work with, to give you an idea of the map we would like to produce. That is also for addressing your question about analytics or visual goal. I think it is just visual. We want to visualize the output of the model on a map. The analysis is performed on model output via multiple regression, apart from the map.
Okay, that is cool. Should not be that difficult, I am a bit tied up until the 20th - but others on the development list should be able to help.
The option "organize your data into a shapefile" sounds good. You mentioned that a geotools program could do that: where do you recommend me to start from (resources/tutorial)? Also a direct reader for my data format could be worthwile, since the task will be perfomed many times (different years, regions, agricultural systems, etc.). Would geotools do that too?
Well I think you would need to read your data format, once you have the information for a single "Feature" it is easy enough to write it out (feature by feature) to a shapefile, or directly to a database.

Thanks again,

Hello,
While working as a visiting scholar at the University of California, Berkekey, I am trying to move an integrated ecological model/GIS system from a propietary platform (ARCINFO) to an open source one (i.e., uDig/GeoTools). 
That is great, I hope we can be of assistance.
My goal is to map the output file of a population model. In the ouput file (see sample attached) each row represents a different location. For each location (beyond Latitude & Longitude) there are plant growth parameters predicted by the model for that location. Tipically, there would be between 100 and 1000 records (rows). These geo-referenced data would hopefully be interpolated in the map.
Some of the people you will meet on this list are from CIP, and have a series of interesting tools that perform some of these kind of operations.
I would like to map such output file using uDig and would like to ask your advice on how to achieve this goal. What tools do I need? Is there anything already available? My background is Entomology (biology) and I am getting some rudimentary Java programming tools.
Well if you can organize your data into a shapefile then you should be able to see it with minimal effort. You could right a geotools program to do that. Or setup a reader for your data format directly, but if it is a one off thing then that may be overkill. 


Is your goal analytics or visual?
