The
Map of Coastal Biodiversity presents many of the data collected during
the implementation of the Project Patagonian Coastal Zone Management
Plan funded by the Global Environmental Facility (GEF) within the
focal area of biodiversity.
The Map was developed using the Geographical Information System (GIS).
This system is a tool to represent reality with a computer. It combines
data located in space by its coordinates – latitude and longitude
– within a digitalized map. Data, in general, are incorporated
in a data base system to allow the corresponding analysis and association.
This data base system allows to establish certain classification depending
on the criteria of accuracy applied:
 Basis topographic maps and maps of uses (city planning, real estate
census, public services, land resources and civil building).
Topological maps or graph maps (maps by subject).
Data incorporated in a GIS system offer different levels of information.
As a result of this, maps can be grouped in |
|
spatial
maps or with geographical locations and descriptive maps involving
features or characteristics.
GIS system has multiple applications: they are ideal to make a diagnosis
of lands and crop growing, prepare inventories of natural resources,
measure impacts caused by weather or ecological phenomena.
This methodology is, at present, gaining importance in Argentina.
It is an efficient and useful tool in planning and administration
of resources. Some of its functions are:
Map overlapping.
Information updating.
Data modeling.
Data presentation in charts.
Feature labeling.
Presentation of characteristics using, for example lines with different
strokes, colors or shapes.
The Map of Coastal Biodiversity
joins maps prepared during different surveys at different scales in
only one map of greater coverage with updated information.
