There is more to preparing the updating of a topographical database than the conception of an appropriate data model. We needed to thoroughly study the available internal and external data sets. Furt...
Over the last 50 years, the Intergovernmental Oceanographic Commission (IOC) has had a profound influence upon the willingness of United Nations Member States to share and provide access to their inte...
Project of building country wide DTM for Serbia and Montenegro is coming to its final phase. The project is based on scanning and vectorization of contours from existing 1:25000 topographic maps. Sup...
High number of geological phenomena – outcropping Pliocene rocks (Red Series), former and recent mud volcanoes, hydrothermal brines rich in Pb and Zn – which can provide significant information to un...
The aim of this study is to validate the Spectral Angle Mapper (SAM) algorithm for geological mapping in Central Jebilet Morocco and compare the results between high and medium spatial resolution sen...
This paper describes the first results of a study, carried out within the national research program “Cofin2001”, on the potential use of high resolution satellite images for making digital orthophoto...
The paper describes the resulst of recent experiments of a project that deals with the combined use of high resolution satellite images, Quickbrid, and laser scanner data to analyse urban images. The...
The use of computer-based visualisations to depict landscape futures is increasingly common in environmental decision-making, particularly where information must be communicated to a wide and non-exp...
The reconstruction of 3D city models has matured to the point where large data sets are now available. As most of the data collection methods used are based on airborne sensors like e.g. aerial laser...
Laser altimetry is a leading technology for the extraction of information of physical surfaces, and hence it is the main source for generating a dense digital surface of the terrain. This results in ...
The paper presents a low-cost navigation system, which is based on digital terrestrial images. The database of the test area is filled by digital images about road junctions, crossings, and other 刬rr...
Many technical aspects are involved in the upgrading of satellite image databases: geometric registration, resampling, radiometric adjustment, mosaicking. In this paper, after an overview of all prob...
A recently instituted National Park, in Southern Italy, is offering a wide experience in landscape knowledge and planning from multiple sources finalized to the environmental analysis. The study is c...
Geographical data sets contain a huge amount of information about spatial phenomena. The exploitation of this knowledge with the aim to make it usable in an internet search engine is one of the goals...
Spatial databases contain feature classes that represent real world. Content of geographic database is mainly designed for GIS analysis. However, a spatial database for cartographic visualization sho...
