TerraCognito Overview TerraCognito Overview Presentation Transcript

  • Project Examples:Spatial Analysis, Visualization & Decision Support Lex Ivey, President
  • MULTI-CRITERIA ANALYSISTerraCognito GIS frequentlyutilizes multi-criteriaanalysis (MCA) in many ofits projects. This powerfulanalytical tool is used in sitesuitability, developmentpreference mapping, traveltime analysis, andgreenhouse gas emissionmodeling.
  • COST-DISTANCE MAPPINGCost-distance mapping is amainstay in many ofTerraCognito’s projects. Itforms the basis for many of ourspatial models including theproximity and travel timecomponent of our developmentpreference mapping process, aswell as the trip distancecomponent of our greenhousegas emissions model.
  • COMMUNITY PREFERENCE MAPPINGTerraCognito GIS has developed Perspective 1: Criteria Ranking: Weighted Drivers Mapa powerful planning approach (Stakeholder Perspective 1)that objectively maps the values More important Infrastructureof citizens and stakeholdersregarding land development andland preservation. Survey Transit stopsresults, keypad polling and other Agreement Mapcollaborative information sources (Perspective 1 minus Perspective 2)are analyzed and mapped to Less important Job centersbuild consensus amongstvarious stakeholders. Basic servicesKey Benefits: Driven directly by values and Perspective 2: Criteria Ranking: Weighted Drivers Map (Stakeholder Perspective 2)preferences More important Driven by local geography Basic services Not limited by hard land usepolygons Objective Job centers Repeatable Transparent Transit stops Consensus Discord Defensible Less important Infrastructure
  • VISIBLE RIDGELINE ANALYSIS Viewshed Analysis Visible Ridgelines Analysis View plane View plane Observer Observer Plan View Plan View 3D View 3D ViewHillside and ridgeline preservation is an important planning issue incommunities where scenic beauty and landscape integrity are valued.Current GIS tools can easily map visible hillsides and viewsheds, butmapping the actual ridgelines, where the visible areas meet the sky, ismore elusive. TerraCognito has created an automated ModelBuildertool and Python script for mapping visible ridgelines, adding morefunctionality to conventional viewshed analysis. Ridgeline analysis isparticularly useful in siting developments, facilities and equipment invisually sensitive areas.
  • STRUCTURESArchitectural ModelsTerraCognito specializes in creating3D models representing terrain,buildings, landforms and otherfeatures that play an importantvisual role in planning. From simplemassing to photo-real architecturalmodels, TerraCognito can createrealistic models for regional andsite-specific projects.
  • TERRAIN & LANDFORMS Tree Species, Density & Height GIS Data Terrain Model Tree PhotosGIS-Driven 3D Visualization Ortho-photo DrapeNot just “pretty pictures,” Forest ModelTerraCognito’s 3D visualizations are Landscape VisualizationGIS-driven, using scientific andtechnical information to createaccurate, realistic models andlandscapes. These can better informstakeholders and allow for bettermanagement and land use decisions.
  • SITE PLANNINGVisualizing the FutureTerraCognito transforms 2-dimensional site plans and landuse plans into compelling 3D representations of future growth. Existing conditions Plan at build-outThis improves public understanding and builds consensusamongst stakeholders, ultimately streamlining the publicapproval process.

  • SITE PLANNINGVisualizing the FutureTerraCognito transforms 2-dimensional site plans and landuse plans into compelling 3-dimensional representations offuture growth. This improves public understanding and buildsconsensus amongst stakeholders, ultimately streamlining thepublic approval process.
  • GROWTH MODELING/IMPACT ANALYSIS Eagle County Build-Out Analysis and Visualization, 2008-2010 Client: Eagle County, Colorado TerraCognito worked directly with Eagle County, Colorado and the municipalities of Avon, Basalt, Eagle, Gypsum, Minturn, Red Cliff and Vail to perform a county- wide spatial-temporal build-out analysis and 3D visualization. Using ArcGIS and CommunityViz, a detailed existing conditions analysis of dwelling units was performed based on assessor and census data, followed by a numeric, spatial and visual build-out analysis of existing zoning as well potential future land use described in the municipalities’ Master Plans. An elaborate visioning exercise was implemented for the unincorporated Impact Analysis Animation (1970-2051) county using multi-criteria analysis and preference mapping to drive future growth scenarios. Later phases of work included an economic component including a commercial build-out analysis, existing jobs distribution, future jobs allocation and impact analysis. Finally, the results were delivered in Google Earth format for viewing by the both the planners and the public. Development Preference Model Customized Google Earth Visualization
  • REGIONAL PLANNINGdemand Growth Animations By matching land supply with the development demand, Terrasupply Cognito creates 4-dimensional depictions of future land use alternatives as they develop over land use allocation several decades.phasing Customized Google Earth Growth Animation
  • COMPREHENSIVE PLANNING Future Jobs & Housing Animation (2011-2060)Branson Comprehensive Plan, 2010-2011Client: City of Branson, MO and Design Workshop Inc.TerraCognito provided key analytical and mapping support increating Branson, Missouri’s comprehensive plan. A detailedexisting land use inventory was created and used as an essentialinput in a parcel-level build-out analysis which identifiedopportunities for in-fill and redevelopment. Multi-criteriasuitability analysis coupled with future demand scenarios andstakeholder preferences enabled the creation of several futureland use plans. Impact analysis was conducted on the land usescenarios including multiple indicators ranging from jobs, wages,and housing affordability, to visible hillside preservation andgreenhouse gas emissions.
  • DAM REMOVAL VISUALIZATIONElwha River Dam Removal VisualizationAmerican Rivers hired TerraCognito GIS to visually model two hillshade rasterproposed dam removals on the Elwha River in Washington’sOlympic National Park. TerraCognito created interactive, photo-realistic, 3D visualization of existing conditions, as well as various random color rampstages of dam removal, including draw-down, riverbed restoration,and re-vegetation. The visualizations were used extensively byAmerican Rivers throughout the settlement negotiation process andin meetings with legislators, ultimately resulting in the impending photo-realremoval of the Glines Canyon and Elwha dams. Commencing in sediment texture2011, the dismantling of the Elwha and Glines Canyon dams willallow the river to flow freely for the first time in 100 years, restoringover 70 miles of salmon and steelhead habitat.

  • WILDFIRE MITIGATION Cost-Benefit Model Landscape Visualization of Forest TreatmentRay Mesa Wildfire MitigationThe Bureau of Land Managements Moab, Utah Field Office hired Lex Ivey to model fire hazard mitigation for a NEPAEnvironmental Analysis, examining the effectiveness of various treatment alternatives, as well as their associated fiscal,socioeconomic, and visual impacts. The consultant defined and weighted several criteria to identify areas that wouldbenefit most from fire mitigation practices. By embedding fuel model data formulated by the U.S. Forest Service (USFS)into the model, the consultant was able to compare current fuel loads in the forest with those that would remain aftervarious types of treatments, such as prescribed burning and mechanical and manual thinning. The model allowed theBLM to measure the effectiveness and cost of the various treatment types, as well as the contribution to the localeconomy in terms of contract labor. The visual impacts of each fire treatment alternative could also be seen in aregional, photo-realistic 3D visualization. The methods, results, methods, and discussion culminated in a satellitetelevision broadcast to all BLM offices across the nation.
  • DAM REMOVAL VISUALIZATIONKlamath River Dam Removal VisualizationAmerican Rivers hired TerraCognito GIS to visually model two hillshadeproposed dam removals on the Klamath River in California. elevationInteractive, real-time, 3D visualization of existing conditions were slopecreated, as well as various stages of dam removal, including draw-down, riverbed restoration, and re-vegetation. aspectThe visualizations were used extensively by American Riversthroughout the settlement negotiation process and in meetings photo-realwith legislators, and in “inspiring” potential funders who may be restoration texturecalled upon to help with the costs of restoration.In November 2008 PacifiCorp (power company), the federalgovernment, and the states of California and Oregon signed anAgreement in Principle stating that the benefits of dam removaloutweigh the potential costs and impacts.
