Global land cover/land use product in multiple periods is pivotal to understand the complex drivers and mechanisms in global climate change, and to forecast future land use trends in sustainable devel...
Road feature is one of the most important features of urban. The change of road reflects construction speed of an urban. map road updating timely and exactly becomes an urgent issue. Current method up...
The usefulness and acceptance of geoinformation systems mainly depend on the quality of the underlying geodata. The aim of this paper is to introduce a system for the verification of geodata. The ve...
This article presents a hybrid method that combines image segmentation, GIS analysis, and visual interpretation in order to detect discrepancies between an existing land use/cover map and satellite im...
The article contains a brief overview of joint research activities (done using GIS methods) in the East European chain of valuable areas of the world connecting five countries: Belarus, Lithuania, Pol...
According to the deficiency of the process in Land Use Status quo Maps updating, this paper puts forward to a way to update The Land Use Status quo Maps based on decision tree, utilizing The Land Use ...
Automated road extraction from images has drawn considerable attention for decades due to the need for the efficient acquisition and updating of road data for geodatabases. The development of new digi...
During the past few years lots of research has been carried out in the field of building extraction from airborne laser scanner data and airborne large-scale imagery. This data can be used to create...
Incremental updating of cadastral database means that master spatial data set is updated when any change (geometric or semantic) occurs, the change can be recorded, updated and provided successively t...
In the recent years, the automated extraction of roads from digital images has drawn considerable attention due to the need for the efficient acquisition and updating of road data for geodatabases. Th...
The updating of road network databases is crucial to many Geographic Information System (GIS) applications such as navigation, urban planning, etc. This paper presents a comprehensive framework for im...
A national topographic database for Denmark was established during the 1990’ies and completed at the end of year 2000. The database comprises three components: A 3-D vector database with full topology...
This study focuses on the problem of "time" affecting spatial data. The most substantial temporal problem for comprehensive use of spatial data is “time inconsistency”. Reducingtime inconsistency” w...
Since the successful launch of IKONOS in 1999, a new source of imagery has been available to the civilian spatial-data user. In many parts of the world high resolution satellite imagery from IKONOS, Q...
The goal of our study was to develop an automatic change detection method based on laser scanner, aerial image and map data to be used in updating of building maps. The method was tested in a study ar...
