Abstract


A geographical information system was implemented using datafrom digital photointerpretation of image of high resolution and fromfield, both related of an experimental area of two hectares, with Araucariaforest, located in the National Forest (FLONA) of Irati-PR, Brazil. Themain objective of this work was to show the potentiality of the integrationof geo-object polygons, representing the contour of crown of trees, withdiverse forest data collected in the field, in a GIS environment guided totwo distinct geo-objects "Tree" and "Parcel". Using the data from thegeo-objetcts, it was possible the visualization of the spatial distributionof the trees and its attributes, to carry out spatial consultations, logicalexpression and groupings. The forest photointerpretation data consideronly the trees with crowns in the up vertical stratus of the forest. Theintegration of the used data in a SIG allow to better understanding somephysiognomic-structural aspects of the experimental area, providingdetailed analysis and visualization of the data of the experiment, necessaryin the forest studies desired to be executed in the investigated area.Key-words: GIS, photointerpretation, studies of dynamics of the forest,forest with araucaria
