Abstract

As old  forest inventory methods, based on questionnaires, become obsolete, a new  procedure using remote sensing techniques has been developed.     The objectives are fourfold:    1. Analysis of the forest situation in Flanders     2. Forest inventory methodology development     3. Creation of a forest management data bank     4. Production of base maps with high planimetric accuracy     Basic material consists of colour infrared 1/30000 transparencies. Photo  interpretation and processing is carried out using a Wild Aviopret APT-1  stereoscope and a Bausch & Lomb Zoom Transfer Scope.     The legend features species composition, development stage, ground cover  percentage, management practice and ownership.     Data from interpretation, field work and supplemental sources are presented  as a series of thematic overlays on a 1/5000 colour infrared  orthophotomap.    Numerical processing is executed on a PDP 11/44 microcomputer. A Wild  interactive graphic system (Synercom) is used for digitizing and area  calculation. Automatic map production is performed on a Wild TA 2 drawing  table.     Availability of stand boundaries in digital form enables generation of  thematic computer maps.
