Opis:
Illegal extraction of gold has grown to be a problem in many countries, causing the degradation of the environment. The main purpose of this paper is to investigate changes in tree cover and surface pollution. The development of a mine site has been observed and analysed with images acquired from Landsat and the Sentinel missions. The results of the study showed changes in the state of the environment, strongly suggesting the possibility of ongoing pyrite weathering processes and the transportation of clay materials down watercourses, which can cause not only the further deterioration of the environment but also slow down the natural regeneration of the forest. In addition, research has found disturbing changes in vegetation, showing a loss of tree cover in the Amazon Rainforest as high as 17%. The validity of using remote sensing methods to observe the development of individual mining sites and their characteristics was confirmed.

Opis:
One of the main priorities of emergency services is to minimize the response time to calls. In the process of proper allocation of emergency vehicles, maps of emergency vehicle accessibility are found to be helpful. These maps represent areas within which emergency services can reach the specified location within a certain time. Calculating travel times requires taking into account the rapidly changing current road conditions. This paper presents a method for dynamically generating maps of emergency vehicle accessibility, considering network models and irregular computational grids.

Opis:
The historical Polegli1939 geoportal is probably the first thematic portal using spatial-temporal databases to present information on people killed during the World War II. In this study, we address the problem of capturing, processing and sharing historical information by supplementing it with a spatial attributes. The aim of the study is to determine the role of crowdsourcing data and the use of web-GIS applications in the process of obtaining and verifying historical information. The study was carried out as part of the implementation of the “Spatial database of soldiers killed in warfare” project, which is also known as Polegli1939. In order to achieve this goal, we acquired information using three methods: manual, automated and Volunteered Geographic Information (VGI). Making spatial data available through the Polegli1939 geoportal enables users to popularize and verify it. The method includes a geospatial web platform (GeoWeb) as well as a VGI application with an integrated process for verifying submitted information. As a result of the project, nearly 35,000 records were obtained. Making the project available to a wider audience opens up the possibility of extending the presented research or replicating it in other countries, taking into account a wider chronological range than just World War II.
