Land is man's most valuable resource. It has to be properly managed if
optimum benefit is to be reaped from it for an ever increasing population.
Increasing population creates a varied demand on land use which cannot
be addressed by a single agency but becomes the responsibility of several
different agencies. Each of these agencies cannot take decisions in a
vacuum and should be able to assess the impact of their decisions on the
others. Use of spatial data enables one just to do that.
Spatial data is information related to any location in the real world.
Information in a spatial format enables one to understand the interaction
of things in their spatial relationships which is just what is required
in land resources management. However, not many planners use spatial data
in their decision making for reasons discussed in this paper.
Acquisition of spatial data is a time consuming, exacting and an expensive
process. Hence there is great need for coordination of efforts in the
collection of spatial data.
This paper discusses what spatial data is available for land resources
management, how it can be used for the sustainable development of land
resources and the advancements in technology that is helping to better
manage our land resources.
