2013 Energy Track, Global Trends Driving the Integration of Geospatial and BI...GIS in the Rockies
Urbanization is occurring at an unprecedented rate representing the largest impact humans have had on the planet. Governments are devoting less of their limited funds to capital infrastructure projects and are looking to the private sector to fill the funding gap. This is driving a focus on construction productivity. Worldwide one third of energy usage is used by buildings. Faced with environmental issues many governments are mandating energy-conservation measures for buildings and for infrastructure. These trends are driving investment in technology. In construction which represents 10% of world GDP, the adoption of building information modeling (BIM) has accelerated in the last decade primarily motivated by the need to reduce the risk of budget and schedule overruns. In addition increasingly architects, engineers and designers are realizing the value of integrating geospatial data and technology into the model-based design process. The integration of geospatial not only addresses specific vertical industry problems such as a mandated low carbon footprint, but also enables a more holistic approach to the major challenges of designing more resilient cities.
This document discusses how to digitize an entire city using GIS-based software to provide a "one touch solution" for representing multiple data types that can be used by government organizations. It outlines the key steps: 1) setting up DGPS control points, 2) conducting a total station survey, 3) performing a drone survey to create a 3D digital model, and 4) processing the data in GIS. Examples are given of the types of information that can be stored in GIS layers and applications of GIS in areas like urban planning, environmental impact analysis, agriculture, and more.
IRJET- Land Use & Land Cover Change Detection using G.I.S. & Remote SensingIRJET Journal
This document discusses land use and land cover change detection in Vadodara, India between 1998 and 2008 using remote sensing and GIS techniques. Specifically, it analyzed Landsat satellite images from those two decades to map and classify land use, including built up area, vegetation, vacant land, and water bodies. The methodology involved image preprocessing like geometric correction and radiometric normalization. Images were then enhanced and classified using both supervised and unsupervised classification. Comparing the classified maps from 1998 and 2008 allowed analyzing changes in land use over that 10-year period and calculating the rate of land consumption. The study aimed to provide information to urban planners for predicting future growth and avoiding problems associated with rapid urbanization.

functionality to conventional viewshed analysis. Ridgeline analysis is
particularly useful in siting developments, facilities and equipment in
visually sensitive areas.

11. 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, R
ed 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 Impact Analysis Animation (1970-2051)
was implemented for the unincorporated
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

Branson Comprehensive Plan, 2010-2011
Client: City of Branson, MO and Design Workshop Inc.
TerraCognito provided key analytical and mapping support in
creating Branson, Missouri’s comprehensive plan. A detailed
existing land use inventory was created and used as an essential
input in a parcel-level build-out analysis which identified
opportunities for in-fill and redevelopment. Multi-criteria
suitability analysis coupled with future demand scenarios and
stakeholder preferences enabled the creation of several future
land use plans. Impact analysis was conducted on the land use
scenarios including multiple indicators ranging from
jobs, wages, and housing affordability, to visible hillside
preservation and greenhouse gas emissions.
14. DAM REMOVAL VISUALIZATION
Elwha River Dam Removal Visualization
American Rivers hired TerraCognito GIS to visually model two hillshade raster
proposed dam removals on the Elwha River in Washington’s
Olympic National Park. TerraCognito created interactive, photo-
realistic, 3D visualization of existing conditions, as well as various random color ramp
stages of dam removal, including draw-down, riverbed
restoration, and re-vegetation. The visualizations were used
extensively by American Rivers throughout the settlement
negotiation process and in meetings with legislators, ultimately photo-real
resulting in the impending removal of the Glines Canyon and Elwha sediment texture
dams. Commencing in 2011, the dismantling of the Elwha and
Glines Canyon dams will allow the river to flow freely for the first
time in 100 years, restoring over 70 miles of salmon and steelhead
habitat.

15. WILDFIRE MITIGATION
Cost-Benefit Model Landscape Visualization of Forest Treatment
Ray Mesa Wildfire Mitigation
The Bureau of Land Management's Moab, Utah Field Office hired Lex Ivey to model fire hazard mitigation for a NEPA
Environmental 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
would benefit 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
after various types of treatments, such as prescribed burning and mechanical and manual thinning. The model allowed
the BLM to measure the effectiveness and cost of the various treatment types, as well as the contribution to the local
economy in terms of contract labor. The visual impacts of each fire treatment alternative could also be seen in a
regional, photo-realistic 3D visualization. The methods, results, methods, and discussion culminated in a satellite
television broadcast to all BLM offices across the nation.
