Forest Cover and Land Use/Land Cover Mapping
of Mazandran Province, using Remote Sensing
Satellite Tm Data, to Prepare Atlas of Study Area
Method
Considering the scale of the landsat thematic mapper (TM) data in bands 2, 3, 4 in the moth of JUN, JULY, JAUNARY 1990, 1991,1993,1994 at the average of 1:100000 scale were applied, the total image was 14 quardrants which cover the Mazxandaran province. For visual interpretation, analysis as reflected through the image characteristics, during the moth of July when the data were scanned most of the agriculture are were harvested or in some part wee not devoid of agriculture, consequently the radiant energy which produced the spectral signature mostlyfor the harvested surface, with communicated a better and usefull-idea to the interpreated that the various image characteristics recorded on the imagery were mainly due to the variation of agriculture area and soil color with the color of exposed stones, and rocks, bare surface in the visual interpretation of satellite images, forest areas were differentiated as a main landuse class and subdivided into subclasses corresponding to different densities, and utilized 1:25000 scale forest typological maps prepared by the forest and range organization. All these interpretation units were correlated and joint with available. C.C.T data in the Mazandaran province, the landue/land covers units wee extracted before collection ground truth for compaced interpretation unite boundary with digital analysis unites and utilized of C.C.T thematic mapper data for land use, the repeated ground controls wee again carried out where necessary, and after the completion of the interpretation of each quardrant of the completion of the interpretation of each quadrant of the satellite images and the appropriate correction were again made, it s notable that in some cases the Global positioning system (GPS) was used to correctly locate certain ground samples.
Material
This project was performed utilized in the preparationof land use maps of Mazandaran area 1:50000 and 1:250000 scale topographic maps 1:250000 scale land capability maps produced by the water and soil research instiute.
1:25000 scale topographic maps produced by the forest and range organization.
