an important factor in sustainable agriculture and economic management is to calculate areas under different crops that the inputs of agriculture connect to this topic. planning of agricultural mechanization, fertilizer and pesticide requirements, pests and diseases control, estimates of agricultural production, income and tax and financial planning, all linked to the cultivated areas and estim...

Areal interpolation between one partitioning of geographical space and another remains an important topic, particular in terms of population counts and related statistics which are often required in order to compute an incidence ratio. Despite numerous recent developments in intelligent areal interpolation methods, and studies that have demonstrated their clear advantage over simple areal weigh...

To construct realistic 3D models of large environments that match the physical world as accurately as possible there is the need to combine several kinds of data sources, such as: ground and aerial laser range scans, tracking data, photos, GPS data, satellite images. In this paper we concentrate on the ground level data acquisition. We present two integrated solutions for automated 3D acquisiti...

This paper introduces a study of morphotectonic structure in the Central Alborz Basin, Mazandaran province of Iran (about 1200 square kilometer), using Russian KFA-1000 satellite photography and sequential air photographs. The KFA-1000 metric camera has better ground resolution than SPOT and LANDSAT for the whole of the study area. Results are provided from one pair of 30×30 cm. photos, which p...

background and objectives: food security has been most important concern of the mankind on the earth. on the other hand, agricultural productions have always been face by risk probability in the case of weather and changes in international markets, however this risk probability never undeleted completely, but could be minimized that by pre-harvesting yield estimation. in this study, different m...

In this study, performance of object-oriented classification approach has been tested using medium resolution satellite dataset of Zonguldak testfield. For this purpose, Landsat 7 ETM+ and ASTER images were used because of their nearly similar ground sampling distance (GSD). As a first step, pan-sharpened images were created based on the combination of panchromatic and color bands available in ...
