ABSTRACT
Future programs of space remote sensing require better
geometric and radiometric resolutions amd the capability to inte-
grate multiplatform data. This paper is intented to describe a
simulation program developped under a contract of the National
Research Council Space Plan for analyzing the geometric and radio-
metric characteristics of a space remote sensing mission. Diffe-
rent aspects of the procedure are described emphasizing the two
essential problems: simulation of a future space platform and
geometric and radiometric preprocessing of raw data. Then some
considerations are given based om prelimimary results obtained on
a particular test site.
INTRODUCTION
The future space remote sensing programs for earth
resources require on ome hand a better geometric and radiometric
resolution, on the other the capability of using multiplatform
data in a geographic informatiom system.
Several procedures have been developped in the last few
years for geometric correction and registration which, starting
from different analytical techniques, have the common need of a
significant number of ground control points (GCPs) (Ref. 1, 2, 3).
These methods, which give quite good results, require an apprec-
ciable man-machine interaction time and are difficult to apply on
areas with a poor cartography or lack of control points.
The increasing performances of space platforms and remo-
te sensing systems have increased the need of simulation programs
in order to evaluate the technological characteristics and to pre-
pare the users for the exploitation of future data.
The authors partecipate with CSATA (Bari) and AQUATER
(Pesaro) to the European SPOT simulation campaign which is coordi-
nated by the JRC (Ispra) (Ref. 4, 5, 6, 7). The italian test site
has been chosen on a particular area of Basilicata which is cha-
