This article proposes the use of the progressive web applications (PWA) for the geographic information systems’ (GIS) web user interfaces. The main advantages of this approach for GIS: use of arbitrary mobile and stationary devices; work in conditions of unstable connection to GIS server with fault-tolerant user input data delivery to the server, when the connection is restored; work offline with the information stored on client device, when the server is disconnected, and automatic synchronization of changed data, when the server connection is active; network traffic savings during data transfer. The above mentioned advantages are important for a number of practical applications in cadastral accounting and construction.
The article discusses the higher educational institutions transition problems to a distance learning operation mode during the pandemic, taking into account the technical universities work specifics. The article describes the problems that have arisen as a result of e-learning mode transition, as well as some solutions to these problems. The article focuses on: the teachers’ readiness problems; the e-courses quality for technical specialities students; the teachers’ developed materials copyright; virtual learning environments to replace the laboratory stands and equipment for students in distance learning process; distance learning educational process implementation technical support problems. The described problems’ proposed solutions’ implementation can be carried out in higher educational institutions without hiring additional personnel.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
