[ai-geostats] R.e. USDA Forest Service Interpolation Contest
Contest website: http://www.fs.fed.us/ne/fia/spatial/interp/ Details on the
conference are at bottom of this email.
To clarify on a few questions I've received about the interpolation contest
idea, yes, the abstract submission deadline is the end of June, but don't
worry about submitting a "placeholder" abstract that describes in general
the approach you will take, and saying "results will be discussed". We're a
fairly informal bunch, and welcome your participation. The conference has a
proceedings which will probably require your paper to be submitted by
December or January. So if you would like to participate, send in an
abstract that best describes what you will do. Once we get the abstracts,
and see how many are interested in the idea, I'll contact those who
expressed interest, and we can go from there. You have until October to
actually do the research.
If you don't have access to or interest in using GIS, the datafile (.txt) is
provided with the gis data such that you can plot the coordinates in your
software of choice. Or, if you really want to particpate and just can't
make a map, I think it would be ok to just have text results. The goal of
this whole thing is to discuss the issues associated with spatial modeling
of forestry data that is like the data we collect on our inventory plots.
Finally, the zero values in the plot dataset are values where there were no
trees, i.e., nonforest areas (or areas without trees that met that diameter
requirements (seedlings)). There are probably some outliers in there (I
noticed that some of the "relative basal area values" that should sum to 1
don't sum to 1 or nearly 1 (e.g., there are a couple that sum to .82 or
.81). This is a bit odd, but I thought I'd leave them in so that users could
show how they might decide to include or exclude points like this.
REMEMBER, WE'RE MODELING TOTAL BASAL AREA (BA_TO), for the contest, but feel
free to experiment with other things as well, (e.g., ba of conifers vs.
hardwoods, ba of a specific genus, etc.) Anything that will address the
general goal. But the specific goal is total basal area.
If you think the idea is of sufficient quality, it would be very instructive
to have a web-based contest modeled on this (which was kind of modeled on
the previous web-based contest on the ai-geostats site!) using these data.
After we get the abstracts, I'll contact those who expressed interest.
Feel free to contact me with any questions (contact info below).
