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.
