Use of a progressive web application for working with Earth remote sensing, topographic and cadastral data layers

Abstract

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.
