Re: [udig-devel] Fwd: Re: Mapping the output of an ecological model with uDig
|
Perhaps I should try for an introduction :-)
Luigi - I was hoping you could talk to someone like Magna (from CIP) as
they also work with biological data and have some neat things going on
in the community section.

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?
