The aim of the master thesis is to develop a web-based GIS application that can be used to access a database of satellite imagery. The developed application allows access to the satellite imagery database and allows downloading of the imagery. The software and technologies used in the work can be divided into two parts: those used to create the database and run the queries, and those used to build the application and connect the application to the database. The database was created beforehand. It was set up locally using Docker, PgAdmin and PyCharm. The web GIS application was built using the Django web framework and the Python, JavaScript and HTML programming languages. The environment for the development of the web application was created using the Conda package and environment management system and its associated command line interface, Anaconda Prompt. We also used a freely available version of the OpenStreetMap world map project, which we embedded in the application as a base on which the user can capture the area of interest. The use of a ready-made web-based GIS application facilitated access to the satellite imagery database by reducing the time to access the data and by allowing the data to be downloaded from the database using a graphical interface without the need for additional knowledge of SQL queries.
