The Regional Programme on Information Systems Management of Marine and
Coastal Resources (CEPNET) extracted the Republic of Nicaragua
coverage from the Digital Chart of the World (DCW) data base.
The dataset is a digital line, point and area representation of
selected base categories of geographic features and characteristics of
these features. The data structure is based on graph theory, in which
a two-dimensional arrangement is expressed as a set of spatial objects
in a manner that explicitly expresses logical relationships. This
concept is used to encode the spatial relationships between the
objects, including adjacency and connectivity between objects and
topologically structured data files to support graphic applications.
The Nicaragua data set depicts information about geographic features on or
near the surface of the Earth. The geographic features are represented
in a six layer digital data set which include a drainage network layer,
road network layer, land use layer, political and administative
boundaries layer, cities layer and a towns layer.
