    • Visualizing Fire Risk Virtual in Earth Dave Bouwman / GIS In the Rockies 2008
    • who is this guy
    • Fort Collins ArcDeveloper Group Fort Collins Alt.NET Group
    • ~ minutes
    • slides
    • live demo
    • Surface Fuels FBPS 1 - Short grass (1 ft.) FBPS 2 - Timber (grass and understory) FBPS 3 - Tall grass (2.5 ft.) FBPS 4 - Chaparral FBPS 5 - Brush FBPS 6 - Dormant brush, hardwood slash FBPS 7 - Southern rough FBPS 8 - Closed timber litter FBPS 9 - Hardwood (long-needle pine) litter FBPS 10 - Timber (litter and understory) FBPS 11 - Light slash FBPS 12 - Medium slash FBPS 96 - Urban FBPS 97 - Non-burnable agriculture FBPS 98 - Water FBPS 99 - Non-burnable, barren 10
    • Fire Occurrence Areas Fires per 1000 acres per year Non-Burnable 0 - 0.024 0.025 - 0.049 0.050 - 0.099 0.100 - 0.199 0.200 - 0.290 0.291 - 0.399 0.400 - 0.599 0.600 - 0.999 1.000 - 1,000 11

    • spatial data in ArcSDE
    • ArcGIS Server Integration
    • users non-technical want
    • relevant answers
    • these users understand
    • “Tools”
    • “Tasks?”
    • “Intuitive?”
    • right tools
    • how
    • 9.3 ArcGIS Server
    • options
    • “baked in” tile caching
    • ArcGIS Javascript Extension for Virtual Earth
    • only supports “fused” caches
    • pre-cache
    • on the fly
    • “other” tile caching
    • tile layer in virtual earth
    • Virtual Earth API
    • VETileLayer
    • quadkey parsing
    • sample code
    • Tile Server* • Opensource • Plug-in model • ArcGIS Server • ArcIMS • Any WMS Server *2nd Prize in ESRI’s 2008 ArcGIS Server Code Challenge
    • TileService Map Server Layer1 Layer2 Layer3 Layer4 Layer5
    • TileService Map Server Layer1 Layer2 Layer3 Layer4 Layer5
    • why wms
    • ?Layers=…
    • Spatial = Slow(er)
    • tables = FAST
    • stored procedure Select * from FIREPOINTS where POINT_X > LONMIN and POINT_X < LONMAX and POINT_Y > LATMIN and POINT_Y < LATMAX
    • Clustering
    • javascript script service (asmx) bbox GetPoints GetPoints Cluster Json { quot;ClusteredPointLocationIdsquot;:[3,5,31], quot;PointLocationIdquot;:3, quot;IsClusteredquot;:true, quot; MarkerClassquot;:firepin, Locationquot;:{quot;Latquot;:-2.15,quot;Lonquot;:-80.53} }
