As digital photogrammetric system developed, we became able to measure three-dimensional objects on a generic personal computer. And recently aerial photograph is easily obtained, for example we can get aerial photograph through internet at a low price in Japan. But three-dimensional measurement using by photogrammetry is not popular. One of this cause is that digital mapping system requires ph...

Abstract. Highly accurate geometric correction is necessary for high-resolution data. Then, it is important to acquire the high accuracy Ground Control Point (GCP) and corresponded Image Control Points (ICPs) for geometric correction. The objective of this study is evaluation of GCP type for high-resolution satellite image. In this study, following two types of GCP was selected: 1)Polygon in fi...

The aim of this study was to establish a preferred methodology for updating of the spatial database and monitoring the changes of a settlement in Tanzania. In summary, change detection problems can be viewed as the consequence of an increased desire for up-to-date information about the development and changes in a GIS environment to guide urban planners, urban decision-makers, and managers. Two...

Unmanned Aerial Vehicle (UAV) systems offered many advantages in several mapping applications such as slope mapping, geohazard studies, etc.This study utilizes UAV system for large scale stream mapping by using digital camera attached to the UAV.The digital camera combined with the UAV form a data acquisition system. This study only concentrates on one type of rotor wing UAV. It is becaue rotor...
