Abstract
Entering the European Union, the Republic of Croatia took over the INSPIRE directive called the National Spatial Data Infrastructure. A large amount of spatial data can be found through the National Spatial Data Infrastructure Geoportal. Data are available for viewing or downloading via different services, such as a web mapping service or web feature service. Although different spatial data are available, it is hard to access useful information through Geoportal. The aim of this paper is to prepare a spatial database which will gather different spatial data related to environmental engineering and present different queries and the visualization of the results. The main data used are related to protected areas in the Republic of Croatia, which register the environmental pollutants, air quality, exploitation and research fields of mineral resources, waste management, water management, and so forth. Alongside the national spatial data, the Copernicus Land monitoring service EU-DEM, the digital elevation model, is used. The classification of Sentinel-2 MSI data is used to provide land cover. Remotely sensed data are used in queries where aspect, slope, and land cover affect the results. Two predefined SQL queries are discussed. The first query discusses the danger of landslides, and the second query discusses threats from illegal landfills and the effect that they have on the environment. Predefined SQL queries enable users to quickly access needed data, even when the original data is updated. All data, databases, visualization, and results are presented in open access software.
Highlights
Today, satellite missions (Copernicus, Landsat, etc.) allow continuous monitoring of the Earth’s surface, which allows us to quickly collect data on space [1]
There is growing evidence that the Republic of Croatia is vulnerable to climate change because it largely belongs to the Mediterranean region where changes are most noticeable in the economic sector because the success of the same sectors depends on the climate factors [2]
Various tools can help us to continuously monitor the state of the environment. In this area of research, a science that can be very useful in environmental engineering, called geoinformatics, is increasingly being used
Summary
Satellite missions (Copernicus, Landsat, etc.) allow continuous monitoring of the Earth’s surface, which allows us to quickly collect data on space [1]. The negative impact on the environment and ecosystems and the emergence of climate change are very current topics in the last five years. Various tools can help us to continuously monitor the state of the environment. In this area of research, a science that can be very useful in environmental engineering, called geoinformatics, is increasingly being used. Geoinformatics is considered a profession of the future and is increasingly advancing in terms of information infrastructure. Geoinformatics technologies include the Geographic Information System (GIS), the Global Navigation Satellite System (GNSS), remote sensing, and spatial databases
