Polygons & Stands: Staying in Sync

1. Polygons & Stands: Staying in Sync GIS and Forest Management: A Practitioner’s Forum October 29-30, 2003 Wilsonville, Oregon James D. Arney, Ph.D. Forest Biometrics JDArney@forestbiometrics.com

6. Basic Gis Functionality • Units are standard between Fps and Gis • Complete Read/Write linkages both ways • Fps – Microsoft Access (97, 2000, Xp) • Gis linkable file structures • ArcView 3.2 - only dBase attribute tables • Arc 8.x - may use Microsoft Access • MapInfo 6.+ - may use Microsoft Access

7. FPS Automated Cruise Selection • Use FPS Menu • Set Sample size • Run Selection • Pass to GIS Map • Go To Field

8. Cruise Selection

9. Harvest Scheduling w/Green-Up

10. Harvest Schedule w/o constraints

13. Fps Database vs Gis Database • Stand boundary was shifted, what next? • New harvest polygon doesn’t match previous polygon boundaries? • New roads have been added? • Stream buffer regulations have changed? • Stand boundaries split at section lines? • Should Riparian buffers be polygons?

19. Adjusting for Road Areas

20. Adjusting for Stream Buffers

21. Lumping & Splitting Polygons

23. Roads layer Road ID Road Label Road Class Class Width Roads Buffer Vegetation ID Area (acres/hectares) Managing Road Reductions

24. Hydro Layer Hydro ID Hydro Label Hydro Class Class Width Hydro Buffer Vegetation ID Area (acres/hectares) Roads included Hydro Row Vegetation ID Area (acres/hectares) Road area removed Managing Stream Buffers

32. Update Fps from Gis • VegPoly (2002) – last year’s veg layer • Gis_ID = Old_ID • VegPoly (2003) – this year’s veg layer • Gis_ID = New_ID • VegStep (2003/2002) overlay split • Old_ID (2002) • New_ID (2003) • Area (acres/hectares) of each sliver polygon

33. Fps Process for Gis Update • Copy CoastFps 2002 to CoastFps 2003 • Open CoastFps 2003 • Link CoastGis VegStep table to CoastFps • Execute “Run Gis Updates to Fps” Menu • CoastFps 2003 database now in sync w/Gis • Update Roads from RoadBuf (2003) • Update Hydro from HydroRow (2003)

34. Order of Flow for Updates • Always start in Gis database with updates • Maintain unique and consistent Gis_IDs • Std_ID may be different, but also unique • Create duplicate of current Gis layer • Make all edits in duplicate layer • Overlay original with duplicate layers • Pass resultant overlay to Fps database • Process overlay updates into Fps database

35. Standard Update Methods • New Roads? – Update Net Forested Area • Modified Hydro Buffers? • Update Road & Stream Buffers in VegPoly • Adjusted acres in existing polygons? • Re-Run Roads & Stream Buffers • Harvest Units? • Run Lump/Split on old/new vegetation layers • Update Road & Stream Buffers in VegPoly
