The aim of this paper is to consider the problem of node localization for geographical routing protocols in ad hoc networks. We propose a distributed positioning algorithm that does not rely only on GPS-like systems (Global Positioning System). Instead, it is assumed that just a part of the nodes belonging to that network is GPS-compliant. Therefore in this paper it is proposed to give position...

Today remote sensing and Geographical Information Systems (GIS) appear quite regularly in the media. Geographical Information Systems are credited with almost magical qualities, whereas "cutting edge" satellite imagery is reputed to be able to do remarkable things such as, for example, reading from space the license plate of a military vehicle. It does not take much imagination to envision how ...

The increasingly widespread use of Geographical Information Systems (GISystems, widely known as GIS) has meant that a version of ‘geography’ has been exported to many other disciplines and walks of life where this technology has been found to be useful. As an undergraduate, one of us read Applied Geography by Dudley Stamp (Stamp, 1960). It is full of ideas and examples of the applications of ge...

One of the most obvious technologies behind Location Based Services (LBS) is positioning, with the most widely recognized system being the Global Positioning System (GPS). There are, however, other means of positioning in addition to GPS. These other technologies are network based positioning and typically rely on various means of triangulation of the signal from cell sites serving a mobile pho...

The paper presents the vehicles integrated monitoring system giving priorities for emergency vehicles. The described system exploits the data gathered by: geographical positioning systems and geographical information systems. The digital maps and roadside cameras provide the dispatchers with aims for in town ambulances traffic management. The method of vehicles positioning in the city network a...

Conservation of historic buildings requires comprehensive and correct information of buildings to be analyzed in conservation decision making process in a systematic and rational approach. Geographical Information Systems (GIS) are advantageous in such cases which can be defined as computer based systems for handling geographical and spatial data. GIS have the potential to support the conservat...

GML is a promising model for integrating geodata within data warehouses. The resulting databases are generally large and require spatial operators to be handled. Depending on the size of the target geographical data and the number and complexity of operators in a query, the processing time may quickly become prohibitive. To optimize spatial queries over GML encoded data, this paper introduces a...

We present a study in which we seek to interpret spatial references that are part of in-situ route descriptions. Our aim is to resolve these references to actual entities and places in the city using a crowdsourced geographic database (OpenStreetMap). We discuss the problems related to this task, and present a possible automatic reference resolution method that can find the correct referent in ...

The article analyzes the possibility of using specialized libraries Python language for processing and analyzing data in geographic information systems. main directions application methods intelligent systems geoinformation, also considers tools analysis.
