The cadastral maps compiled as we have al ready mentioned, which are supplemented by aerial and space conventional and multispec- tral data imagery are used in land-use moni toring. In view of these facts, methodologies to use aerial photographs in land-use moni toring have been established; these photo graphs are a real and efficient information source supplying a large data volume exis ting in the field. Obviously, results are de pending on many factors, among which we men tion: aerial photograph and photosensitive material qualities, the best period selec tion, emphasize on phenomena to be monitored, the best aerial photograph scale selection, equipment, human operator experience and skill in aerial photograph, data and infor mation interpretations. Several accomplished themes related to land-use monitoring could be mentioned: study on land evolution within hydromeliorative sys tems, land-use monitoring within settlements, and monitoring surfaces, on which garbage and industrial wastes are to be found. Some other themes are to be approached, using also other data sources such as multispectral data deli vered by aerial and space platforms, aiming at the development of a complex cadastre be ing able to permanently monitor land-use, in real time. - On land evolution within hydromeliorative systems In the last decades, large irrigation and drainage systems have been developed in va rious country zones. Aerial photograph ta king in some special time periods, these ae rial photograph interpretations, and conclu sions presented to the decision-making units are recommended, to monitor their running effects on the respective fields. Studies using 1:12,000-1:15,000 soale ae rial photographs and photogrammetric products over diked areas in the Danube Delta and ir rigation systems in other country zones have been made, in order to develope a proper me thodology. The execution project related to canal network, the respective system running efficiencies, and the secondary effects(marsh formation, salinity,a.s.o.), efficient land- use in farming, according to the land manage ment projects, and land cadastre updating were implemented in the above mentioned stu dies. The developed methodology recommends : ta king aerial photographs during periods of time when the respective systems have a maxi mum load, carrying out photogrammetric docu ments emphasizing excess moisture, correla tion among excess moisture zones and micro- relief shapes, excess moisture surface map ping and estimation, correlation between the respective zone photographic image and the corresponding map showing the isophreatic lines emphasizing the field excess moisture), densitométrie measurements using diagrams and interpretations, as well as, phenomena which cannot be percieved by visual photointerpre tation, correlation among types of soil ha ving vegetations covering excess humidity surfaces, according to the photographic image. - On land-use monitoring within settlements Towns and villages are permanently and in tensively extending; as a result of a new and impressive social, cultural and economic de velopment. The national land resource legis lation provides allotment of lands for va rious fields of activity, without diminishing farming and forest surfaces. Periodical 1:20,000 scale aerial photographs are taken, to supervise these legislation provisions, aiming at: the settlement building limit i- dentlfications, field identifications within the settlements to be built, and their use previous to the dwelling development and put ting under crop the lands, which temporally were improper to agriculture because their wrong uses. - On monitoring surfaces on which garbage and industrial wastes are to be found Concentrations of wastes, cinder, slag and refuse are permanently carried and deposited in large usual natural holes on non-produc tive fields. Stockpiling in densely popula ted towns and large industrial plants have always brought about serious problems, be cause it must comply with the legal provi sions regarding health safety conditions, soil, water and air pollutions. The studies implemented, and which have used aerial pho tographs recommends: identification of far ming lands covered by wastes, stockpiling approval checkings, depositing dynamics moni toring according to the technical documenta tion, its effect on the neighboured zones, putting lands under crop, according to the schedule, based on the established projects. Stockpiling zones for garbage and indus trial wastes for some large towns with heavy industries have been studied, using 1:4,000 scale periodical aerial photographs used as a base for 1:500 scale topographic mapping; hole stockpiling volume has been calculated according to stockpiling rate; filling dia grams have been developed and, finally, put ting these lands under crops. Some themes on the national land-use moni toring have been briefly presented, using ae rial photographs and photogrammetric docu ments. Methodologies for all approached themes are developed using the above men tioned studies. Space multispectral imagery taken in the course of the last mid-decade (Zegheru 1976) has been experimentally used to monitor the national land-use, for the first time in our country.
