• Involving citizens in science through mobile data collection and online analysis. We propose modern system architecture (SaaS & desktop GIS). describe a toolbox which transfers GIS geoprocessing to ArcGIS Online. test our WebGIS solution on OOH media visual pollution as use case.

This study focuses on the assessment of drought severity, employing a comparative analysis between normalized multi-band index (NMDI; calculated using Sentinel-2 imagery) and combined indicator (CDI). The research aims to pinpoint most accurate reliable remote sensing techniques, which reflect ground-based measurements, thereby enhancing precision monitoring systems. By investigating specific area Małopolska, not only contributes global knowledge base methodologies but also addresses...

The article is composed of two sections. In the first section, authors describe application minimum line dimensions which are dependent on shape, width and operational scale map. proposed solutions based Euclidean metric space, for Saliszczew's elementary triangle (Elementary – term pertaining to model, standard least securing recognizability a line. Its depend map representing it. use in simplification process as follows: triangles with sides (sections) an arbitrary bases (completing sides)...

Crowdsourcing is one of the spatial data sources, but due to its unstructured form, quality noisy crowd judgments a challenge. In this study, we address problem detecting and removing crowdsourced bias as prerequisite for better-quality open-data output. This study aims find most robust assurance system (QAs). To achieve goal, design logic-based QAs variants test them on air crowdsourcing database. By extending paradigm urban pollution monitoring from particulate matter concentration levels...

application of satellite remote sensing methods in mineral prospecting kosovo, area selac introduction Satellite techniques have been used for environmental research over 45 years.Moreover, geological has become a separate scientific subdivision that found its many problems.The information can be obtained with the use varies according to sensors.The most commonly are: airborne laser scanning, multispectral and hyperspectral optical scanners (Cloutis

Abstract The correct estimation of ambulance travel time is an extremely important issue from the perspective healthcare and security citizens. In some events, threat to health or life injured person increases with each minute waiting for ambulance. authors this article analyzed how ambulances throughout entire Lesser Poland voivodeship in southern Poland. Based on analysis 300 million GPS records that were collected over several years ambulances, real speed characteristics compiled most...

The commonly used methods in digital cartography are based on the minimum dimensions of black and white objects. This article presents a solution which both colour symbols background they presented relevant context setting objects map. To achieve this, authors have developed perception coefficient that is an extension formal definitions object dimensions. In support solutions, offer several cartographic examples. also contains experimental research examines impact recognition by means...

The main purpose of the research is to achieve fully automated approach for supplying multi-resolution databases with linear objects in each scale. Moreover, proposed solutions maintain repeatability and accuracy output data wherever possible according input These properties are achieved by keeping minimal object dimensions as well appropriate pre-processing, based on classification source points. distinguishes three classes points: constant (unchangeable), temporary, inherited. build a...

This article presents a concept of decision support system for emergency flood embankment stability. The proposed methodology is based on the analysis data from both em-bankment measurement network and generated through numerical modeling. Decisions about risk failure are made this analysis. authors present general as well preliminary detailed description components.

Abstract The article presents comprehensive documentation of the situation post-mining Miedzianka village (former town), which is located in Lower Silesia, south-western Poland. Due to long-term expansive mining exploitation since 14 th century, over time was completely destroyed and depopulated, thus nowadays, only a few inhabitants live there. basis for conducted research area were changes land urban structure that have been occurring centuries connection with operation copper uranium....

The main purpose of research was to achieve data integration between Database Topographic Objects (BDOT) scale 1:500 and BDOT 1:10000. presented approach assumes the construction a complex Extract, Transform, Load (ETL) process for harmonization built-up areas that supplies 1:10k dataset with most accurate geometric derived from base map. Full attributes BDOT500 BDOT10k databases achieved by constructing an ETL using Talend Open Studio Data Integration [17]. Geospatial vector stored in...

Problemem poruszanym w niniejszym artykule jest czas, jakim obliczana kompletna mapa czasow dojazdow pojazdow ratunkowych (ambulansow) dla zadanej siatki. Znalezienie optymalnej (najszybszej) trasy miedzy dwoma punktami problemem zlozonym i czasochlonnym. Co wiecej, poruszane zagadnienia wynikają z potrzeb problemow, ktorymi zmagają sie dyspozytorzy Malopolskiego Ratownictwa Medycznego. Wobec tego, intencją autorow bylo opracowanie metod pozwalających na skrocenie czasu wykonywania obliczen,...

This paper presents the method of 3D visualization environmental thermal images.Method use images experimental river embankment.This kind can be useful for leaks and anomalies detection.The authors GIS, due to monitored data capabilities their integration into a single coherent model.The infrared images, taken from different perspectives distances, are placed on model soil embankment.The special precociously contact remove distortion was applied.This approach allows analysis types...
