This paper reports the progress as well as the improvement in the methods being used in the development of drainage maps of fine detail from aerial photographs of the several counties of Indiana. This drainage mapping, which is about 25 percent complete, is a part of the current highway research program at Purdue University; it is conducted by the State Highway Commission of Indiana and the Joi...

This study introduces and evaluates a new methodology using information on image spatial form (spatial metrics) to describe structures and changes in urban land use. The metrics were calculated for segmented areas of homogenous urban land use structure derived from digitally classified color infrared aerial photographs. The results indicate a useful description and separation of three urban lan...

The author examined the effects of human responses to automation alerts and nonalerts. Previous research has shown that automation false alarms and misses have differential effects on human trust (i.e., automation false alarms tend to affect operator compliance, whereas automation misses tend to affect operator reliance). Participants performed a simulated combat task, whereby they examined aer...

The advancement in digital photogrammetry has made photogrammetric technique become simpler, faster and lower cost. Currently, this method is quite popular in covering small and large area. This study examines the use of digital camera of high resolution in capturing aerial photograph based on unmanned aerial vehicle (UAV) as the airborne platform. The study area covered is the area of Universi...

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...

Cartography and other applications of remote sensing have led to an increased interest in the (semi-)automatic interpretation of structures in aerial images of urban and suburban areas. Although these areas are particularly challenging because of their complexity , the degree of regularity in such man-made structures also helps to tackle the problems. The paper presents the iterated application...

In this paper, we propose a new method to generate a digital map from the aerial photograph. For map generation, it is necessary to develop a technique to recognize various naturaland artificialobjects in the image by computer processing. In general, a photo image has spatial and spectral informations. It is desirable that these two informations are effectively utilized. A new method proposed h...

This paper will discuss an invented approach which focuses on providing an output from registration of an aerial photograph on a 3D model such as DTM, DMS, or 3D model. The approach has been developed in order to omit distortions from output and to increase the reliability. In contrast of other image registration methods which their outputs are an image, this approach provide a 3D model which c...
