in local government - Assessors responsible for judging the value of
all taxable properties in jurisdiction - Details about properties include ownership,
address, land and building value, and tax
exemptions
29GIS in tax assessment
- Method
- GIS used to collect and mange geographic parcel
boundaries and associated property information - Basic tax assessment task involves database query
to locate all sales of similar properties within
a given distance - Property to be valued is identified in property
database - Geographic query performed to pull values of all
comparable properties within 1 mile radius of
property - Properties displayed on assessors screen
30GIS in tax assessment
- Result
- Assessor can compare the characteristics of
properties (lot size, sales price, and date of
sale, neighborhood status, property improvements,
etc) and value the property

small-level geography (e.g., CT or ZIP) - Identify variations in the incidences of customer
types - Often supplemented by lifestyle data, such as
shopping habits or consumption choices
35Market area analysis
- Assess the distribution of retail outlets
relative to the greatest concentrations of
potential customers - Increasing field/service in many types of
agencies, public and private - Improves public service planning in health,
education and law enforcement - Geodemographics used as basis for analysis
36Examples of Business and Service PlanningGIS
applications
37Market area analysis 1
- City of Escondido abandoned Kmart site
- City contacted SANDAG to assist with the sale and
redevelopment of abandoned site - 19 acre site, located on Mission Avenue next to
State Route 78, vacant since March 2003 - Land planned for redevelopment Mixed-use
commercial and residential
38Escondido abandoned Kmart site
- Method
- Demographic data gathered to profile area
- Current and forecasted demographic and economic
data (population, median income) aggregated for a
10 mile radius of site - Maps produced to display neighboring land uses,
future plans, and area characteristics - Existing land use, general plan, and population
and housing density
39Escondido abandoned Kmart site
- Result
- Data used to predict the success of
- New commercial development in local market area,
- Sale of new housing units (based on similar house
values) - As marketing tool
40Market area analysis 2
- Tesco Grocery retailer in UK
- Success through
- Strategic diversification

44Logistics and Transportation
45Logistics and Transportation
- Deal with movement of goods and people from one
place to another and infrastructure (highways,
railroads, canals) that moves them
46Logistics and Transportation
- Logistics Companies (e.g., parcel delivery and
shipping) - Addresses the shipping and transportation of
goods - Organize operations, parcel routing, origins and
destinations - Where to put sorting warehouses and transfer
facilities
47Logistics and Transportation
- Transportation Authorities
- New routes
- Where to build
- Highway conditions
48Logistics and Transportation
- Transit Authorities
- Plan routes and schedules
- keep track of vehicles and incidents that delay
them - Provide information to travelers
- All fields employ GIS applications to handle
day-to-day operations
49Applications overview
- Each has two parts
- Static
- Deals with fixed infrastructure
- Dynamic
- Deals with vehicles, goods, and people that move
on static part
50Transportation
- Historically, GIS easier to apply to static part
- Today, use of GPS
- Track vehicles as they move
- Transit authorities use to inform users of buses
and trains - Deal with emergency incidents occuring on
transportation networks (OnStar)
51Logistics
- GIS helped many service and delivery companies to
reduce operating costs in field - Optimization
- Design of solutions to meet specified objectives
- E.g., A delivery company needs to deliver parcels
to 200 locations in one shift, dividing work
between 10 trucks - Different ways of dividing the work, and routing
vehicles, can result in differences in time
cost - GIS logistics applications determine optimal
routes based on shortest distances, time of day,
traffic volume
52Example of Transportation GIS application
53Planning for emergency evacuation
- Overview
- Tool allows neighborhoods to rate potential for
problems associated with evaluation - Develop plans accordingly
- Uses GIS database on distribution of population
in neighborhoods - Street patterns
- Result Evacuation vulnerability map
- Assumes worst-case scenario for location
54Planning for emergency evacuation
- How it works
- Assumes one vehicle to evacuate each household
- Looks further than household location
(cul-de-sac? Street have only one exit?) to
locate bottlenecks - E.g., Densely packed neighborhood, single exit
massive evacuation problem - Resulting maps draw attention to areas of
potential problems
55Evacuation vulnerability map
- Method
- Two types data for analysis
- Population and household counts, number of
vehicles (Census) - Street centerline files (Census TIGER and USGS)
- Both free
56Evacuation vulnerability map
- Analysis
- Begins at every street intersection, works
outwards following street connections to reach
new intersections - Every connection tested for bottleneck (total
number of vehicles/number of exit lanes) - After all streets tested, worst-case value
(vehicles per lane) assigned, resulting in
network of values

63Example of an Environmental GIS application
64Deforestation on Sibuyan Island
- Sibuyan Island, Philippines Overview
- Problem Deforestation poses major threat to
biodiversity - Objective Identify development scenarios to
anticipate future land use and habitant change,
and as a result anticipate changes in
biodiversity - Sibuyan small island (area 283 sq mi), steep
forested mountain slopes, coastal land used for
agriculture, mining and human settlement - Biodiversity 700 plant species (54 only occur in
Sibuyan)
65Deforestation on Sibuyan Island
- Method
- Qualitative
- List of factors influencing to land use patterns
- E.g., suitability of soil for agriculture (ideal
or not) can increase likelihood that area will be
stripped of forest and used for agriculture - Quantitative GIS-based analysis
- Calculates the probabilities of land use
transition under three scenarios of land use
change
66Deforestation on Sibuyan Island
- Quantitative GIS-based analysis
- Scenario 1 Assumes no effective protection of
forests on island - Scenario 2 Protection of the designated natural
park alone - Scenario 3 Assumes protection not only of
natural park but a GIS-defined buffer zone
67Deforestation on Sibuyan Island
- Techniques
- Digitizing of land features and classification of
imagery to obtain a land use map - Correlation and regression analysis between
location factors and land use - GIS simulates scenarios of future land use change
based on different spatial policies - Measures connectivity and fragmentation of
forest, affecting ability of species to mix and
breed without disturbance
68Deforestation on Sibuyan Island
- Results
- 3 land use change scenarios (maps)
- Show decreasing deforestation (increasing
connectivity, decreasing fragmentation),
respectively, from Scenario 1 to 3
