PSU-NWCC Spatial ServicesHDGIS project meeting 12 – 1:30 pm January 24, 2011PSU Cramer Hall 413 Agenda • Project group personnel update • Year 1 BAGIS summary and discussion • Year 2 HDGIS update and discussion
In attendance: • Lesley Bross • Geoffrey Duh • Dave Garen • Gus Goodbody • Ray Hennings • Rich Jain • Jim Marron • Tom Perkins
BAGIS Year 1 SummaryOctober 1, 2009 – December 31. 2010 • BAGIS model (for ArcGIS 9.X and 10) • Development: Oct 1, 2009 – April, 2010 • Beta testing: April – June, 2010 • V1 released: July 2010 • Latest version: Ver1_F • Data compilation (22 different datasets with hundred GB of data) • Model execution (601 AOIs with 700 GB data) • Final report – BAGIS User’s Manual
Release notes: BAGIS Ver1F Updates to Release E • BASIN Tool: Added double-warning for selecting not to reuse BASIN dem • BASIN Tool: Added function to snap BASIN clip boundary to DEM raster cell boundaries to prevent unmatched AOI boundaries created from different BASINs • AOI Tool: Modified the clip AOI tool to allow longer AOI path name and improved error handling routine • About: Disclaimers added • AOI Utility: Added function to let users add AOI additional layers to map by selecting from layer lists • AOI Utility: Fixed AOI boundary not showing up on the map when the BASIN tool was not used to select AOI • Generate Maps: Fixed Excel charts plotting errors for SNOTEL, Snow Course, and precipitation charts.
HDGIS – Key Features • ArcGIS 10 Add-in tools • HRU Zone Delineation • HRU Delineation Factors • Pre-processing and templates • HRU Zone Post-processing • Dissolve • Specialized dissolve/clustering • Limited by HRU number • Dissolve based on similarity • Data management • Definition file (AOI HRU management)
HDGIS File Structure - Input Internal PRISM (monthly, quarterly, annual) (AOI_FOLDER/layers/prism/…) User layers (AOI_FOLDER/layers/…) Internal DEM (DEM, Slope, Aspect, etc.) (AOI_FOLDER/output/surfaces/…) Internal HRU (generated by HDGIS) (AOI_FOLDER/output/zones/…)
HDGIS File Structure – Output HRUs Zones folder (AOI_FOLDER/output/zones/) Individual HRU subfolder (AOI_FOLDER/output/zones/HRUNAME/) HRU factors (zones/HRUNAME/layers/…) Raster factor name: RXXX_LAYERNAME/grid HRU raster: grid HRU vector: grid_v.shp XML: log.xml
Pre-processing Options for Rules • Majority Filter (discrete data) • Low-pass (smooth) filtering (continuous data)
Rule templates • Aspect • Azimuth to directions (4, 8, or 16) • Remove DEM artifacts and speckles • Slope • Low-pass filtering on slope • Slope (degree or %) to slope grades (1: 0 – 5%, 2: > 5%) • Remove DEM artifacts and speckles • Canopy density • Low-pass filtering on % canopy • % canopy to canopy grades (1: 0 – 30%, 2: > 30%) • Remove speckles and small forest patches • Land-use/land-cover • USGS Anderson scheme to hydrological scheme (bare, grass, shrubs, trees) • Remove speckles and small land-cover patches • Soil • Rasterize soil vector data • NRCS soil scheme to hydrological scheme (sand, loam, clay) • Remove speckles and small soil patches
HDGIS Development Schedule • Development platform evaluation (07/10 – 08/10) • System requirements: ArcGIS 10 (SP1) or later • Design and coding (09/10 – 03/11) • Staged beta-testing (04/11 – 07/11) • Initial release (July 2011) • Final release (September 2011)
