Systems involving remote sensing analysis for airborne and satellite d
ata in combination with geographic information systems are large and c
omplex. The Canada Centre for Remote Sensing (CCRS) has created an exp
ert system shell and several expert systems in order to provide image
analysis programs with the necessary knowledge to solve difficult imag
e processing problems, such as updating a forest inventory geographic
information system. An interactive task interface (ILTI) provides an e
xpert system with a Prolog module designed to answer queries from the
image analysis program by retrieving knowledge from an image analysis
knowledge base, the analyst advisor. Image analysis experts currently
create ILTI's. They have found this to be a time-consuming task. An in
cremental/adaptive planner has been developed that will create a plan
that emulates the ILTI's behavior by analyzing image processing sessio
n dialogues between a human expert and an image analysis program for s
everal cases of forest updates. The planner relies on a knowledge base
in order to generalize and modify plans acquired from session dialogu
es. The planner speeds and simplifies the creation of new expert syste
ms.
