and to the management of the public resource (Hassan and Hutchinson 1992).
Conservation and resource management is increasingly interdisciplinary and
interdepartmental in nature. Building the capacity to contribute to and receive
from the rapidly growing body of data is a valuable product.
Implementation of Digital Mapping Technologies in Tropical
Developing Countries
It is useful to evaluate the costs and constraints in implementing digital mapping
technologies. Successful applications have been demonstrated in the utilization
of image analysis, GIS, and GPS (table 3.1). The three technologies have been
applied in measurement of deforestation, identification of suitable habitat for
various species, and a variety of protected area wildlife management issues.
However, the initial investment in advanced mapping technologies is high, and
many remote sensing technology transfers have failed to address the unique

conditions of the recipient country (Forster 1990). The reasons for failure in
technology transfer within developed countries are similar to the causes of
failure of technology transfer in tropical developing countries, but the quality of
conditions in tropical developing countries makes technology implementation
more difficult.
The implementation of an information technology such as GIS or image
analysis can be evaluated along the three major components of the information
system—hardware and software, data, and staff (figure 3.1). The concept of the
GIS as a triangle was developed by the author to stress the balance required in
investments and activities in each of the three components in a well-functioning
information system. A successful implementation plan should address all three
components. Excessive focus often is placed upon hardware and software considerations, particularly if competing vendors are involved. Often, agencies are

The presence of any two components should produce the third component.
