The application was developed with the support of a specific university research at the University of Ostrava. It is the product of team work of Department of Biology and Ecology, Institute for Research and Applications of Fuzzy Modeling and Department of Informatics and Computers. The first idea to create this app originated 5 years ago, and its author was nobody else than a singer, photographer and student of the Department of Biology and Ecology, Dan Bárta. He turned to Aleš Dolný from the Department of Biology and Ecology with the basic idea of the classification based on species-specific characteristics of morphology, ecology and biogeography, which could allow users to easily identify all czech dragonflies up to the species level. This project has been intensively developed over the last two years, mainly due to the above mentioned cooperation with other experts not only in biology, but also in mathematics and informatics, such as Michal Burda, Stanislav Ožana, and last but not least Michal Hykel, Marek Malina, and Martin Prášek. Together, we managed to create an application for identification and monitoring of dragonflies, which main purpose is not only to popularize this insect order and nature among the general public, but also its involvement in the collection of data, in the context of the activities referred to as citizen science. We believe that the data obtained by our app will lead both to higher awareness of the occurrence of each species, as well as indirectly to protect endangered species and their habitats.
