KNOWLEDGE-BASED SYSTEMS FOR COPING WITH CLOUDS David G. Goodenough, Dena Schanzer, and Michael Robson ABSTRACT The Canada Centre for Remote Sensing (CCRS) is developing a system of hierarchical experts for resource inventories, known as SHERI. The focus of the SHERI Project is to create knowledge-based systems for updating forest geographic information systems with remotely sensed imagery. This development is being done in cooperation with the Inventory Branch of the British Columbia Ministry of Forests (BCMOF). The production goal of BCMOF is to be able to update 1500,1:20,000 scale, forest maps per year. To achieve this goal, BCMOF must make use of remote sensing imagery containing some clouds (up to 15% of the scene). This paper deals with our knowledge-based systems for detecting clouds, smoke, and haze in Thematic Mapper imagery. The systems must also identify snow and water in the shadows of the clouds. It is not possible to interpret the forests directly cloud-covered. Therefore, these regions must be used to mark forest polygons which are not yet updated in the scene. The result is that the majority of a forest map may be updated, but there can be some forest polygons which were not updated because of clouds. These particular forest polygons are noted in the overall system in the event that cloud-free imagery covering these polygons becomes available. The paper describes the features used for cloud detection, the accuracies obtained, and the methods used to manage the agenda for future updates of the forest inventory. 160
