The document discusses the applications of remote sensing and GIS in diagnosing and managing problem soils, highlighting their roles in agriculture, forestry, geology, and urban planning. It covers processes involved in remote sensing, such as data collection and analysis, as well as the objectives of GIS in optimizing decision-making and data management. The author acknowledges various sources that contributed to the content of the presentation.

2. Remote
Sensing
• Remote Sensing: The art and science
of obtaining information about an object
without physical contact between the
object and sensor
• The processes of collecting information
about Earth surfaces and phenomena
using sensors not in physical contact
with the surfaces and phenomena of
interest.

15. GIS OBJECTIVES
Maximize the efficiency
of planning and
decision making
Provide efficient means
for data distribution
and handling
Elimination of
redundant data base
minimize duplication
Capacity to integrate
information from many
sources
Complex analysis/query
