The International Thermonuclear Experimental Reactor (ITER) fusion project's council has put back for a year an announcement on its updated timeline for the project - and is proposing other changes in...
This paper proposes an automatic approach for residential areas revision by means of analysing the correlation between the residential area and the topographic and geographical factors. The approach c...
The article describes the creation of initial three dimensional geodatabase from planning and designing through the determination of technological and manufacturing processes to practical using of Cen...
Poorly designed charts are prevalent in reports, magazines, books and on the Web. Most of these charts are only available as bitmap images; without access to the underlying data it is prohibitively...
Geographic information systems (GIS) are dependent on accurate and up-to-date data sets. The manual revision of GIS data is very cost and time consuming. On the other hand more and more high resolutio...
Demand for up-to-date geographic data is increasing due to the fast growth of Geographic Information System (GIS) technology. GIS requires up-to-date data in order to provide reliable answers to geogr...
The production system of middle-scaled topographic maps of the National Land Survey of Finland was re-engineered in 1992-1993 when a new Topographic Data System was introduced. After that data compila...
In general, built-up areas or populated places are significantly changing within the revision interval of a GIS (Geographic Information System) or map. In this paper we present a method by means of wh...
The aim of this study is to use different image analysis and processing methods in order to extract information content needed to update large scale maps. Recently available high resolution satellite ...
Nowadays because of high potential of satellite images, maps production procedure and their updating increasingly go towards using satellite photogrammetry. With regard to Iran's restrictions to acces...
Change extraction of building is needed to revise building data effectively. Many change detection algorithms use height difference analysis using temporal data such as LIDAR. However, remarkable cha...
Revision of 25K topographic maps is one of the main duties of General Command of Mapping (GCM). Up to now, revision is carried out by stereo photogrammetric methods using 35K aerial photographs with ...
Nowadays, due to improvements in satellite technology, remote sensing data is used for mapping at different scales. In Iran, there is a necessity to utilize satellite imagery as a complementary data s...
With the growing use of digital map data, the requirements for frequent and efficient revision of digital map databases is equally growing. Revision of map databases can be divided into 3 steps...
CHANGE DETECTION METHODS FOR THE REVISION OF TOPOGRAPHIC DATABASES.
