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 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

11 Harvest Schedule with green-up constraints

12 Common Parameters Fps Admin table –Gis_ID –Flag –PlanYear –Xgis & Ygis –Physical Site Index –Basin –Elevation –Aspect –Slope Gis VegPoly table –Gis_ID –Flag –Theme –Xgis & Ygis –Site Index –Basin –Elevation –Aspect –Slope

13 Fps Database vs Gis Database Stand boundary was shifted, what next? New harvest polygon doesnt 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?

20 Adjusting for Stream Buffers

21 Lumping & Splitting Polygons

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

24 Managing Stream Buffers 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

25 Managing Vegetation Polygons FPS Access Database Admin table –Std_ID –Gis_ID –Area_Gis (Gross) –Area_Net (-Roads) –Area_Rpt(-Rds & Hyd) GIS Access Database VegPoly table –Gis_ID –Std_ID –Acres (hectares) –Roads –Buffer (hydro)

32 Update Fps from Gis VegPoly (2002) – last years veg layer –Gis_ID = Old_ID VegPoly (2003) – this years 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
