This paper presents accuracy and stability of orbit modeling. Orbit modeling is carried out using the stereo strips which were taken by SPOT-3 satellite, a large number of GCPs(Ground control points) ...
The rigorous geometric model which depends on physical properties of the image acquisition is the basic model for object positioning of high resolution satellite imagery (HRSI). Using the linear and a...
Cartosat-1 satellite, launched on 5th May 2005, is designed to deliver high-resolution spatial data of better than 2.5m in stereo with~27 km swath. The twin panchromatic cameras (Fore & Aft), with a f...
The improving capability of the direct geo-referencing technology is having a positive impact on the widespread adoption of LiDAR systems for the acquisition of dense and accurate surface models over ...
The production and updating of paper chart is always the theme to the guarantee and improvement of hydrographic chart, in which the quality detection and control is the key to consider. At present, ...
The heart of any spatial systems is its strong reliable database. The spatial database is a complex in nature which requires special technical skills to maintain it. The discrepancies in database can ...
This paper presents results from a Direct Mapping Solution (DMS) comprised of an Applanix APX-15 UAV GNSS-Inertial system integrated with a Sony a7R camera to produce highly accurate ortho-rectified i...
We propose a novel image-based strategy for a sub-decimetre quality georeferencing of Mobile Mapping Systems in urban areas. The presented approach uses very high resolution multiple-view calibrated a...
The basic image product of Quickbird PAN data contains information about satellite position, velocity and orientation information together with interior orientation parameters. The model utilizes th...
This contribution gives account of one of the results achieved by the group MAPA (Models and Algorithms for the digital documentation of Architectural Heritage) that integrates the IMAP3D group and th...
In terms of research dealing with acceleration of technological and measuring processes during operating earth moving machines, a technological procedure of operating quality control of machines by me...
The problem of locust mass breeding in Russia became more and more urgent. Last outbreaks of a locust in the West Siberia, Kazakhstan and the Caucasus have evoked considerable interest of scientists ...
The Poyang Lake is the largest fresh water lake in China, of which the vast area is about 39955 km2 . The Poyang Lake Area, on the other hand, is the place where floods often occur. In order to redu...
Digital spatial data are underlying strong temporal changes. The typical approach of updating these changes is to check the data manually by superimposing them on up-to-date orthoimages from aerial or...
The GPS precise surveying which is prevailing in Korea now grasps the problem that the result of the GPS observed value is used without the analysis of the relationship between the geometric strengt...
