Photointerpretation and Remote Sensing Methodology

 

Basic Presuppositions and Infrastructure

Before we start investigating a real world problem by remote sensing methods and techniques, first we must:

BULLET.JPG (677 bytes) know the general characteristics of the study area and collect the existing appropriate information to use (topographic, cadastral and thematic maps, statistical tables and charts)
BULLET.JPG (677 bytes) know some concrete specific characteristics of the area (e.g.urban patterns, geological landforms and structures)
BULLET.JPG (677 bytes) know the objective possibilities and constraints of remote sensing sensors/systems with regard to the specific demands of the specific application (e.g. it often takes more than a single sensor to adequately address all of the requirements for a given application)
BULLET.JPG (677 bytes) have the specialised scientific knowledge related to the problem’s requirements (each application itself has specific demands)
BULLET.JPG (677 bytes) design and implement only the necessary and appropriate field controls and sampling procedures (field analysis). More than necessary ground checking results in more expenses whilst less than necessary checking results in decreased expected accuracy.
