Use
of Geographic Information Systems (GIS) has continued to
increase in Belize over the past years. To date no
one has found a definition that satisfies everyone. GIS
is most commonly defined as any of various software applications,
running on a PC or Workstation that captures, manipulates,
analyses, stores, and displays layers of geographically-referenced
data. While there are many different types of software used
in the office place today for drafting, database management,
and graphic design, they are not considered to be GIS because
they are not able to perform spatial queries and answer
questions relating to locations, condition, trends and patterns.
The power of GIS lies in its ability to manage spatial relationship
over time.
The
Coastal Zone Management Institute manages a large amount
of data, both tabular and geographical in nature. Geographic
Information Systems (GISs) have most often employed vector
data because, its flexibility allows users to easily attach
attributes and perform queries and calculations. However,
with the introduction of high-quality georeferenced raster
images, GIS designers are increasingly incorporating raster
layers to visually enhance their systems and provide a Geographic
Information System with the benefits of vector data combined
with the visual impact of raster images.
The Data Center acts as an integral supporting arm for the Coastal
Zone Management Institute. The functions of the
Centre is to develop and maintain a Geographic Information
System, that is capable of analyzing data, both spatial
and non spatial data. The Centre is equipped with the latest
GIS and Remote Sensing software and hardware such as ERSI
software products, a 48 inches SummagridV Digitizing Tablet
and a Hewlett Packard Design Jet 1055cm plotter.
At
this time when Belize’s population is increasing and
tourism is soaring, natural resource managers are discovering
the power of GIS. In 1995 when the Coastal Zone Management
Unit of the Fisheries Department was established, GIS was
chosen as the tool to help in managing the coastal zone
of Belize. Today GIS is helping the Coastal Zone Management
Institute (CZMI), Government, and Non-Government Organizations
in Belize, in finding common ground, by providing a framework
for the analysis of resource management data. The technical
staff at the CZMI is using GIS as an aid to monitor trends
and assist in the making of critical decisions. Patterns
and critical habitats are easily identifiable by integrating
both spatial and non-spatial data into our GIS, where it
is organized, analyzed, and spatially displayed (mapped).
GIS
enables the development of such scenarios that can test
static as well as dynamic hypotheses about resource use,
changes and alternatives given model inputs and outputs.
This allows for different options to be studied in a cost-effective
and non-hazardous manner. GIS provides a powerful visual
aid to both technical and non-technical audiences in developing
a better understanding of the issues/problems facing us
today.
The Data Centre stores all spatial and attribute data derived
under the different technical/research units of the Institute.
Among the most used and requested corporate layers of the
Institute are the Coastal
Protected Areas of Belize, the Marine
Habitat, for the entire coastal area and the
Manatee
Sightings layer. A complete listing of all GIS
layer/coverage that exist in the Data Centre is available
at the CZMAI main office.
