EARTHQUAKE
DISASTER MANAGEMENT THROUGH GIS AND PROBABILISTIC
RISK ASSESSMENT
Poor people in developing countries are
particularly vulnerable to disasters mainly
because of where they live. Published research
shows that they are more likely to occupy
dangerous locations, such as flood plains,
river banks, steep slopes, reclaimed land,
and highly populated settlements of badly
constructed shanty homes.
The earthquake that devastated Bam in Iran
in December of 2003 killed more than 40,000
people primarily because their housing was
not designed to handle a major tremor. The
availability of a probabilistic risk assessment
tool may have better prepared the government
to handle the situation.
The paper describes how the use of geospatial
technologies coupled with accurate data
and probabilistic risk assessment can help
local authorities and international agencies
better prepare for coping with natural disasters
in general and earthquakes in particular.

ADVANTAGES
OF LIDAR IN FLOOD MODELING AND IMPORTANT
PARAMETERS FOR LIDAR
LiDAR is a relatively new technology that
can be used to accurately geo-reference
terrain features. Higher accuracy, less
time for data collection and processing,
least human intervention, and weather and
light independence are some of the key advantages
offered by this technology, over other conventional
methods of topographic data collection.
LiDAR technology provides very high resolution
data through which important parameters
for flood dynamics and flood propagation
such as dykes, constructed river banks,
and roads can easily be identified.
This paper highlights the use of LiDAR technology
to extract high resolution DEMs and its
associated benefits.

PROCESSING
OF HIGH RESOLUTION DIGITAL TERRAIN MODELS
(DTM) FOR EFFICIENT WATER RESOURCE MANAGEMENT
Automated extraction of hydrological features
from DTM is gaining significant importance
because of the availability of high resolution
data. The derived hydrological features
are not only spatially accurate, but they
also significantly enhance the overall quality
of modeling projects such as water resource
management and flood risk modeling.
However, processing high resolution DTMs
also has some serious issues such as handling
artifacts and depressions, and these issues
compound as the resolution of DTM increases.
Furthermore, processing high resolution
DTM is extremely time consuming particularly
when dealing with artifacts (man-made constructions
across the rivers) and depressions.
Natural depressions like pot-holes and sinks-holes
play an important role, especially in the
derivation of hydrological features like
river network and watersheds. Moreover,
the presence of artifacts also creates secondary
sinks.
This paper demonstrates the best possible
ways of handling artifacts and depressions
while deriving hydrological features from
high resolution DTMs.

LANDSLIDES
IN BHUTAN DUE TO HUMAN INTERVENTIONS - REACTIONS
OF A FRAGILE GEO-ENVIRONMENT
Landslides are not uncommon in the Himalayan
foothills of Bhutan. The geo-environment
comprises a fragile and highly pulverized
lithology. It is embedded in the Himalayan
Main Boundary Thrust fault and is seismically
active. The area also experiences intensive
rainfall which increases pore water pressure
and makes it favourable to landslide occurrences.
However, the landslides have significantly
increased in the past few decades mainly
due the rapid developmental activities taking
place in the area.
Phuentsholing is a major industrial and
business hub in Bhutan. A couple of mega
hydro-electric projects and few industrial
development projects have come up there
in the recent past. Such rapid urban expansion
and human intervention has negatively impacted
the entire landscape of the city. The frequency
and occurrence of landslides has increased
and this has in-turn effected people, transport,
property and cultural monuments. The best
known examples are, landslides hampering
the supply of vital goods to the capital
(Thimphu) and other places, threatening
the cultural monument Gumpha
(A Buddhist temple), crop loss, and flash
floods.
This paper attempts to highlight how urban
development and human intervention is threatening
the basic geo-environment around Phuentsholing
city in Bhutan.

GIS
UTILITY MAPPING AND NETWORK MANAGEMENT
Analysis and modeling is an effective tool
to help organizations enhance their processes
to improve efficiency and to effectively
use their technology. Utilities are one
of the most important and basic needs of
today's community & under increased pressure
to improve efficiency, while at the same
time, offering new services within the current
limited and often declining resources. With
the usage of GIS in the Decision Support
System the overall efficiency can be increased.
The "fault detection & analysis in Utility
distribution network" is proposed to be
developed as an integrated plan encompassing
all faults which were occurred in any distribution
network. GIS has emerged as a very important
tool for effective planning, management,
communication, and training in various stages.
Customized GIS database can play key role
in this aspect by providing cost-effective
information at various stages.
Apart from fault detection & analysis
it can be used for making a billing system,
to trace theft in the network, defaulter
customers & hence over revenue generation
of the organization shoots up.
This paper highlights the utility network
geo-database with emphasis on current technological
trends being used right from data development
stage including decision makers.

3D
CITY MODELS FOR URBAN GIS
Due to the increasing availability of information
systems and 3D data, planners and municipalities
are focusing on modeling the urban space in
3D. A particular focus is given to the effectiveness
of GIS and its related methods for their capacity
to accommodate the demands of visual representation
of urban environment as well as the basis
for analysis and simulation.
In this paper the authors present a framework
for 3D urban GIS and the concept of digital
cities as a social information infrastructure
for urban life (including shopping, business,
transportation, and education). The proposed
architecture for digital cities includes:
- City mapping (integrates
both data archives and real-time sensory
information)
- Digital City Model (DCM)
- Value added services
- Surveying
- Integration of field
updates.
These 3D models deliver a true picture
of the ground and enable the users to view
the location of services and real places
in an intuitive and user-friendly way. These
models are useful for multifarious applications
such as transportation management and planning,
disaster management and micro telecommunication
network planning.

LAND PROFILE EXTRACTOR
Geographical Information Systems provides
the civil engineer today with tools for creating,
managing, analyzing, and visualizing all types
of geographic information. This information
can be related to both the project and its
broader geographic context. GIS is thus playing
an increasingly important role in civil engineering
projects, supporting all phases of the design
cycle.
In India too, Government and non-government
organizations such as municipalities, planning
and architectural firms, and real-estate
organizations, are increasingly realizing
the power of using such technologies to
make their systems more efficient.
This paper presents a practical usage
of a variety of geospatial tools that can
be of significance to the community working
on 'built form'.

REMOTE SENSING - A COMPARISON WITH SUPPLY
CHAIN SOURCES
While the reliability and accuracy of
remote sensing data is routinely checked
through systematic sampling and ground verification,
there has never been a large scale accuracy
check that was commodity-based via the supply
chain. In this paper the authors have made
an attempt to scientifically compare remote
sensing-based data with supply chain sources
such as millers, exporters and wholesale
commodities markets. This first-of-its-kind
study was undertaken to assess the accuracy
of remote sensing-based production estimations
of Basmati rice for the 2005 growing season
against the actual arrivals at various grain
depots as well as other related sources.
The survey was conducted through export,
wholesale and marketing boards of Basmati
in four leading rice-producing states in
India: Uttar Pradesh, Uttaranchal, Punjab
and Haryana.
Based on a comparative analysis between
Kharif (monsoon growing season) 2005 estimates
derived using remote sensing, versus the
actual arrives at market, a March 2006 conclusion,
based on certain calculated and logical
assumptions and limitations found that the
remote sensing-based estimated results for
Kharif 2005 harvest provided an accuracy
of 90% to 94% in the study areas. As anticipated,
remote sensing based data as expressed in
estimates is higher in a predictable manner
than total supply chain sources, thus confirming
the reliability of this project's data.
The authors consider this to be a cautious,
well calculated and mathematical analyses-based
study done for the first time in India.
Results are re-defining certain usage of
remote sensing techniques in agriculture
market research and supply chain study.
This study may also have an application
in calibrating demand forecasting as well.

CUSTOMIZED
SOLUTION FOR ENTERPRISE GIS USING ARCGIS
ENGINE
Today's Enterprise Geospatial framework
requires effective deployment of geospatial
applications for various facets of data
analysis, editing and rendering requirements.
ESRI ArcGIS Engine with the help of rich
set of components can facilitate custom
applications, interfaces and cost-effective
deployment. This requires only an ArcGIS
Engine runtime or ArcGIS desktop license
per computer. By customizing with disconnected
editing, one can significantly improve the
performance and reduce the load on the ArcSDE
server.
ArcGIS Engine provides a set of developer
controls that simplifies the programming
model for including mapping functionality
in the applications. It gives the flexibility
of customized interfaces for displaying
and editing spatial data and can club several
interactive development environments to
create advanced GIS applications. Disconnected
editing avoids network constraints and allows
organizations to disseminate their enterprise
geospatial data across the departments for
improved business effectiveness.

GIS
FOR COMPREHENSIVE TAXATION SOLUTIONS
Special Purpose Districts (SPD's) are
created by state and local agencies for
the purpose of funding special items such
as Library Districts, Regional Transportation
Districts, Crime Control Districts, etc.
SPDs play vital role in implementing sales
and use tax that is collected in addition
to state tax and any other local taxes.
Frequent changes in municipal boundaries
due to annexations make it difficult for
retailers to determine local tax jurisdictions
and manage tax issues. With tax jurisdictions
constantly changing and new tax jurisdiction
assignment requirements mandated by state
and local lawmakers, the potential liability
resulting from inaccurate tax assignment
poses a significant problem.
The ESRI suite offers a range of flexible
functionalities, which can be used to build
a comprehensive solution to ensure that
the most current information is available
for tax jurisdiction assessment. This paper
illustrates a solution that involves in
creating a nationwide SPD product and periodic
product maintenance to enhance the tax application
performance.
