Abstract

Green land is counted as one of the important parts of each city, especially in Tehran which is considered as the metropolis. Recently, the development of urban green area is becoming a great concern. For proper managing of each source, first the inventory of that source is taken into the consideration. Regretfully so far there has been no comprehensive studios pattern for studying the situation of URBAN FORESTs and urban green area.In this study, by describing the AERIAL PHOTOS, the urban green area has been classified. After performed surveys, it was certified that CLASSIFICATION on numerical ORTHO PHOTO MOSAICs is easier and more precise, comparing with manual description, and consequently this method was used. The studying Zone is zone No. six, one of the 22 zones in Tehran metropolitan districts limited as to north to Shahid Hemat highway, west to Chamran highway, east to Modarress highway and finally south to Enghelab Avenue. The whole area reaches to some 213.56 hectares equal to 3.3 percent of area of Tehran. (Five years development program municipality no. six, year 1996).On the basis of present data, the per capita green space in studying district is about 4 square meters. (The aforementioned development program)The boundary of the studying zone and in accordance with flight available index, the numbers and technical data of required photos have been digitalized. It is noted that the photos of the area are prepared in the form of "Dispositive scanning" during year 2002 in two scales of 1:8000 and 1:10000. Then by using height digitizing model, the surface(ground) control points, and using the software" PCI Geomatica version 9" all the photos have been modeled as ortho type. In the study, the method of preparing ortho digitizing one has been used. Next step the AERIAL PHOTOS available, in the scales 1:8000 & 1:10000 have been modified. In the same equal scale and have been put aside each one. In fact we have prepared digitized ortho photomozaic and visible CLASSIFICATION on the basis of covering layers which have been later described, have been completed. Such layers have been prepared on the basis of previous completed studies together vision of the researcher over digitized ortho-photomozaic photos as well……
