In-Depth Information
GIS technique is a reliable tool for spatial planning based on the level and
quality of information generated. Its ability to integrate multi-scale and multi-
temporal data from diverse sources makes the platform a powerful force for
contemporary development and problem solving.
The robustness of the GIS driven procedure prescribed in this chapter
further demonstrates the quality and nature of its results. The series of maps
produced and the database system generated are indispensable tools for
decision makers, regarding flood management and risk analysis.
The results are well simplified especially for policy formulators who do
not have strong knowledge for interpreting spatial data. This is promoted by its
geovisualization capability which provide quick visual impression of the
pattern and degree of vulnerability.
However, the results have a parallel link and application to public policies
especially those related to urban and town planning in the study area. For
example, evidence from this analysis point to the conclusion that urban
planners need to revisit the water body setback policy. The flood mask
generated through integrated procedures will be highly beneficial when the
setback legislation is set for review. In addition, when decision makers decide
to take a more drastic measure concerning the safety of the general public by
relocating activities and residents from the floodplain and risk zones to risk
free areas, the created database will serve as a guideline for such a project.
The identified flood prone areas, infrastructures and population based on
vulnerability class provide range of options and will undoubtedly assist in
priority ranking. The integration of the flood risk data with Google map will
help to explore building structures and track down residences (including their
spatial location) that are exposed to a particular risk magnitude. Such spatially
synchronized database would facilitate campaign and enlightenment program
by presenting basic spatial information on flood risk and vulnerability. This
can be done by collaborating with Google map makers to upload the flood
mask data to the internet through their map server from where individuals can
access it at any point and time.
