Spatial Data Management Group Meeting, Thursday, February 21, 2013 @ 10:00 a.m.; Richardson 313

Attendees: Candice W., Cole, Dave, Heather, Keith, Kelly, Kiira S., Kuuipo, Patti, Peter, Ray, Terralyn, Theresa

Treats: Keith

Notes: Dave

Facilitator: Theresa

Topic: More on Lidar? How are people using it.

Theresa presented a demo on the LAS tools available in ArcGIS 10.1, including the LAS Dataset toolbar, which allows the user to generate aspect/slope/elevation/contours easily, and also has a 3D viewer of the points.

We discussed whether the Mosaic Dataset option would work to get access to the raw Lidar data available at the College of Engineering. The task of creating these datasets to serve them over the web/network is a big job in itself. Theresa will experiment with creating a LAS dataset that maps to the Engineering data.

Cy Smith, State of Oregon Geospatial Information Officer, reportedly has a plan to serve all the Lidar-derived rasters via Oregon Explorer. (DOGAMI’s data, plus others?)

Keith worked with Ray Davis to analyze different methods to do stem (tree) mapping – Popescu, USFS, Fusion, etc.

Patti has a lot of Lidar data from Sheri Schneider, USGS Oregon Geospatial Liaision. She will check about whether all of her data is on Engineering already. If not, Patti will tell Kuuipo, who will check with Engineering to see if they want it.

Could people put their Lidar indexes/boundaries on T:\GIS?

Meetings:(for information only)

• Willamette Valley GIS Users Group, Winter Quarterly Meeting: Albany at the Albany City Hall on Feb. 28, 2013, 1-4 pm. 333 Broadalbin St. SW, Albany. There is a social following.
• GIS in Action: April 30-May 1, 2013, Portland State University;
• Open Source meeting? Date/time, place?
• ESRI International Developer Summit: March 25-28, 2013, Palm Springs, CA,
• ESRI Federal GIS Conference: February 25-27, 2013, Washington, DC
• 2013 Northwest GIS Users Conference: October 14-18, 2013, Sunriver, OR,

Software/Hardware:

• New Plotter – from the Portland lab, a replacement for the 60” plotter in FSL 217
• Sean San Romani is installing SDE 10.1, so it will be available.
• Keith tried installing 64-bit background processing for Python. It hasn’t broken anything. He now has three versions of Python on his computer – v2.7 pre-ArcGIS install, the version installed with ArcGIS 10.0, and the new one.

Data:

• Patti has the 2012 NAIP imagery for Oregon, in 1-meter resolution quarter-quads, MrSID CCMs (Color County Mosaics). 1.5 TB total.

Training:

• Python – Theresa is doing a 2-day remote USFS training.
• Python: Scripting for ArcGIS – Patti has the book. It is ArcPy focused.
• She also has the Getting to Know ArcGIS: ModelBuilder book from ESRI Press. If anyone wants to borrow either of them, let her know.

Round Table:

• Ray – Working on fire forecast data. They are in production mode, posting once/month at three sites for seven months out.
• Candice – Geosciences PhD student, GIS support person; a student had a question about Network Analysis – how to use it to find the best route to a main road from multiple schools
• Peter – Working on validating a rapid shade model, using vegetation (tree heights) and topography.
• Keith – Question about calculating statistics from overlapping polygons – couldn’t find much, so he wrote a Python script to do it. Patti said that Curtis Price, USGS GIS guru, wrote a toolbox that addresses this.
• Dave – Assessing different GIS methods to collect data from multiple users using a combination of maps and forms. Analyzed ArcGIS Online/ArcGIS Server, Google Earth, and Data-Driven Pages. Would be willing to do a SDMG demo of the options. // Also realized yet again that one must check the Environments carefully when doing raster geoprocessing, to make sure the output extent and cell size is as you expect it to be.
• Kuuipo–Worked with Dawn Wright to get Lauren Scott, ESRI, to come to OSU for a talk at Geosciences at Tuesday, Feb. 26, on Beyond Mapping: Using Spatial Statistics. esri.com/spatialstat
• Heather – Working with Landsat time series data. They are finding a gradual increasing brightness overall over time. Why? The data comes from LandTrendr, but not from their processing. Maybe it’s sensor drift?
• Kiira – Looking at mercury levels in fish and differences in space/distribution across the western US: Western Mercury Synthesis. Had a question about the best way to do reprojections.
• Patti – Bing Maps is going away (for free in ArcGIS). NGA/Digital Globe – imagery web services available for federal employees.
• Cole – Working with Ray Davis on the Lidar analysis. Desktop Manager (not sure what this is)
• Theresa – Working on LandTrendr and producing metadata (fun and exciting!).

Next Meeting: March 21

Topic: Ray Davis and stem mapping? John Sharrard on 10.1 or 10.2 or AGOL?
