The paper addresses the problem of automation of the processes related to Earth remote sensing data and derivative product processing, analysis, and presentation. A web-based interface technology has been developed that provides the user with tools for graphical modeling of workflows. The technology aims at a transition to the creation of ready-made software solutions in the form of application services based on high-level needs, which does not require development of a software code. The underlying concept for the transition is a low-code concept that helps transform the development cycle of specialized software for remote monitoring of territories through complete or partial elimination of the software code development stage. The workflow is considered within the workflow management paradigm and is associated with an application task solved by the user in a highly specialized context. Each workflow is an ordered set where the elements are software modules for interaction with Earth remote sensing data, third-party services, storage and visualization systems. The need to develop the claimed software technology is substantiated. Preconditions for the workflow model development, requirements for the system functional blocks, software environment, graphic notation elements and software interfaces are formulated. The outputs were used in agricultural monitoring tasks, including tracking the crop condition dynamics, vegetation heterogeneity, temperature mapping, as well as in the tasks related to obtaining and cataloging remote sensing data from various satellite systems in the Earth remote sensing data warehouse of Siberian Federal University School of Space and Information Technology. Development potential of the technology and its performance features for a distributed architecture are considered.
Keywords: Earth remote sensing from the space, geospatial data, workflow, Low-code, graphical process editor, visual designer, executable processes, satellite data processes, functional modules, operator, web-interface
