Treats: John Wells
Notes: Matt Gregory

Speaker:

Spatially Explicit Modeling of Alternative Futures using VDDT/TELSA– a presentation by Dave Hockman-Wert

Dave gave us a presentation of his upcoming talk at the USGS GIS symposium in Denver. Dave and his co-authors are using VDDT and TELSA to model alternative futures for southern Coastal Oregon watersheds, using current vegetation and various policy and disturbance scenarios. His PowerPoint is posted here (powerpoint document). He fielded a number of questions about the methodology of VDDT and TELSA for spatially explicit modeling.

Meeting Agenda:

Meetings:

Keith (and maybe Theresa) will be attending the ESRI users’ conference in July

Upcoming training:

Data:

Theresa gave a demonstration of the Benton County 1m color mosaicked NAIP imagery. They appeared to be somewhat image-matched, but other counties aren’t necessarily as good. As reported before, it will be at least September until these data are available through a map service. BLM is in the process of quality checking the ½-meter imagery for release. The imagery will be projected into UTM zone 10, NAD83.

Round Table:

Keith: He has been working on using GDAL for resampling imagery on the fly and has discovered some strange behavior in so doing. He will be going to the ESRI User Conference and is hoping to attend the pre-conference workshops.

Dave Hockman-Wert: He would like feedback on his presentation before his Denver presentation. He is attending the USGS GIS workshop next week.

Theresa Valentine: She has compiled the 1936 Oregon and Washington Historical Vegetation GIS layer onto fordata. The data is available at T:\gis\pnw and is called bvbh1936 Historical note: this coverage was created by none other than HJ Andrews. She was also going to add a link to a bald eagle nesting site webcam as the April image of the month.

Kelly Christiansen: He and Kelly Burnett have been working on developing an intrinsic potential model for chinook in the Coast Range. He has also been working on the SWAM tool which is a tool for delineating small catchments around basins. He highly recommends renting AirJaws 1 & 2, the DVD.

John Wells: John has been working on getting the MAPPS and MC1 models to compile and run on the vitis cluster, but has been struggling with some out-of-date Fortran code. He is hoping that a possible rewrite of the MC1 model will happen in the near future

Sean Gordon: Sean is doing his PhD in Forest Resources and came to see Dave’s talk about VDDT/TELSA and how it might apply to his research

Matt Gregory: The LEMMA team has hired a new faculty research assistant (Heather May) who will be starting at the end of April and will be doing database/GIS/analysis research on vegetation models. He also publicized that his team had finished mapping Ecological Systems for Eastern Oregon and Washington through the GAP program.
