quantitative identification of physical changes, developments and dynamic position of urban green space is considered as the first step in its planning. by means of the aerial photos taken in 1956, 1974, and 1994 as well as the quick bird satellite image captured in 2006, this study has dealt with changes in per capita green space in khorramabad during these years. first, geometric corrections ...

The georeference of any photogrammetric product is based on the reconstruction of the geometric relations of imaging in a chosen object coordinate system. For the handling of aerial photos traditionally the bundle of rays from the image points over the projection center to the ground points is modelled by means of the camera calibration information and the exterior orientation determined by mea...

Two kinds of method, raster fusion and vector fusion, is proposed for fusion operation by integration of LIDAR point cloud and Ortho aerial photos in this paper. The data set used in the paper and data process for preparation is introduced firstly. In order to complement the raster fusion, the points cloud is interpolated into a raster style by Inverse Distance Weighted(IDW) method using Z and ...

Remotely sensed data offer a global coverage, with variable spatial, radiometric, spectral and temporal resolutions, and are the major source of geo-spatial information. The importance of cities and their structural complexity and continuous change make the use of such data even more necessary. In this chapter, we will limit ourselves to remote sensors that can facilitate the extraction of basi...

In this paper, a new smooth slideshow transition effect, Sewing Photos, is proposed while considering both of smooth content transition and smooth camera motion. Comparing to the traditional photo browsing and displaying work, which all focused on presenting splendid visual effects, Sewing Photos emphasizes on the smooth transition process between photos while taking the photo contents into acc...

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 ...

The Bayesian inference along with the step-by-step technique allows foresee a possibility to increase the efficiency and reliability of phototriangulation. It also appears to improve the strength of the block, in order to increase the economy with respect to control points. The used methodology consists on simulation of a 25 points mesh, from which a block of aerial photos is generated. Random ...

The present paper focus on the rectification of QuickBird imagery (Standard PSM True Color image) in order to update the urban planning of Parikia (Paros island, Greece). Although the spatial resolution is sufficient for such application and the radiometric information is often better than the case of existing aerial photos, an accurate geometrical calibration is needed.The methods applied in t...
