4- An Application of Geospatial Analysis
- Environmental Indications and Warning
- Environmental Issues - Societal Stress
- Food production, freshwater resources,
water/air pollution, - land use change (deforestation,
desertification, urbanization) - Affect public health, agriculture and industrial
development, - demographic patterns, local through national
political - alliances,economic growth, infrastructure
planning, - crisis response capabilities.
- Affect political, economic and social dynamics
- And are exacerbated by
- continued rapid population growth and migration
- natural hazards and weather variability (shock)
events -
5- Value of GIS Technology
- Environmental Issues are spatial in nature with
global - to local origins
- Environmental Issues are dynamic (process and
time series) - Environmental Issues are subject to natural
changes, - anthropogenic stressors and shock events
- GIS facilitates trend analysis and what if
scenarios - GIS provides a strong interface to remote
sensing sources - Visualization is a strong analysis and
communication tool - GIS provides a platform for the integration of
other data -
6- Environmental Outlook
- South Asia with a focus on India
- Urban population modeling
- Population Density Change (1960, 1998, 2010)
- Urbanization Risk (2025)
- Natural Disaster Vulnerabilities severe storm

19- Summary
-
- Digital Earth will introduce new ways for
researchers to - assess interactions of humans and nature.
- Land use change dynamics such as urbanization
can - be readily captured by satellite remote
sensing. - Subnational (disaggregated) population models
assist - analysis of risk due to land use change, or
natural hazards. - Cartographic modeling is of value to visualize
change - dynamics and explore implications.
- Data are becoming more complete, precise and
accurate. - Trends and alternative scenarios can be modeled
as well - as assist in their evaluation.
- Built up spatial information systems can be
used to examine - what if scenarios conduct rapid assessment
of real events. -
