I am curious as to how many of you are doing (or interested in
some GIS mapping/analysis of your tree/forest data? Perhaps we
have a discussion if there is the interest.

Gary's offer may be the opportunity some have
been looking for. Gary
established the GIS department at HCC and is the driving force
insuring its viability. He works daily with GIS so this could be
important opportunity for discussing conceptual analytical

That is an excellent offer. Doing GIS mapping/analysis of the
forest data is the way the info should be organized. If I
actually had any
data I would send it to you in a minute. I strongly encourage
this group to pursue this suggestion and discussion.
For people curious about GIS but not exactly sure what it is I
several links that give some basic description of what it is:
If people pursue this offer a short succinct description of
"What Is GIS?"
should be included on the ENTS website so that I do not need to
commercial external source.

Thanks Ed....I began the GISlab at the College with an NSF Grant
years ago...we have 20 Dell desktop computers, full size
large format HP Deskjet (USGS size maps), and for software we
license with UMASS that includes ARCGIS 8.3, ArcView 3.3,
ERDAS, and IDRISI.
I've got a Pentium 4 Laptop with 1 GB RAM so I can do most of
Mapping right on my laptop at home or in the field. A Toshiba
and a a Garmin Etrex Vista allows me to map realtime in the
field if I
Bob Leverett and the rest of our research group are going to
georeferencing all of the trees in the database we have (over
then we can begin using the ARCGIS program to map and analyze in

hoping that the ones Will is referring to are updates with even

I have been thinking about GIS usage for ENTS Data. For the
GIS stands for Geographical Information Systems and consists of
graphical database in the form of maps. Each type of information
want to analyze is coded on a separate layer. Then these layers
combined in different ways to emphasize the features of
example, one layer could be the topography for a site, a second
the underlying geology. Another the soil map for the area, a
map for the area, a vegetation map, political map. Any type of
be encoded into the system. Some data is best represented by
other data can be encoded and used to generate contour maps
gradations between data points. Individual points can be linked
external text files that may include descriptive or
information. GIS is the next step above standard data bases for
managing natural resource information.
I am wondering on what scale you want to manage the tree data
ENTS is generating? Do you want to concentrate on a few areas,
a broad based coverage, or a combination of both? What kind of
information to you have in your base GIS data sets? Certainly
topography, but what about, geology, soils, rainfall, climate?
be useful for people who might be contributing to the project to
from what information you are starting.
What types of information do you plan to encode into the GIS
Tree height, girth, species information? Rucker indexes for
areas? Tree age data? What information do you already have would
include in the GIS maps?
What types of information do you think would be useful for
collect for thie GIS project? Start with what you think is
information (GPS locations) and other information that would be
have to round out the data sets?
I know you have thought about this for awhile, how do you
GIS materials to be organized? What “layers” do you think
practical? What kind of information would not be represented
the system? Could you just provide an overview of what you are
with regard to this proposal?

At the ENTS Rendezvous at Cook Forest in April I plan to give an
GIS (for the beginner and intermediate user) and provide some
sense of what
GIS could do for ENTS. I'd like to start the demo with the broad
view of the
entire Eastern U.S. so if any of you have some tree measurements
start simply with name of the measurer, species, cbh, height,
coordinates)that you would be willing to share for my demo at
Cook it would
be greatly appreciated. A tabbed text file, Excel or Dbase
Access would be fine. I'd like some actual numbers representing
states in the eastern U.S. Also, if any of you are interesting
your data or yourself into GIS please let me know.
Eventually I want to work with Ed Frank to get some of this up
on the ENTS
website. "So many trees and so little time.."

I will be using ARCGIS 9 and so whatever data I am going to
include in my
presentation I will need to have at least two weeks before (I'll
be in the
Smokies the week before). Folks can send me their data as an
an email message (<10 Megabytes, I have cable internet) but I
folks just have a few trees with good geographic coordinates.The

dBase file or Excel file:

would be wonderful...if the coordinates are in UTM (include the
even better...some may be in State Plane Coordinates.
There is much to do if I want to try and pull off a GIS
data from around teh Eastern U.S. so people need to get it to me
There is so much potential with this Ed...I am excited about
how to get started.
Oh..where as ArcExplorer is a baby GIS VIEWER you can not create
layers in it...so people could view my stuff with it but not be
create their own GIS database with it. Such is the case with
Whatever you need for explanation or information let me know, I
questions and I love to share methods and techniques.
