Cloud-Desktop Remote Sensing Data Management to Ensure Time Series Analysis, Integration of Qgis and Google Earth Engine

Abstract

Abstract. Our context research is conducted to investigate the possibility of common application of the remote sensing and ground-based monitoring data to detection and observation of the dynamics and change in climate and vegetation cover parameters. We applied the analysis of the annual graphs of Normalized Difference Water Index to estimate the length and time frames of growing seasons. Basing on previously gained results, we concluded that we can use the Index-based monitoring of growing season parameters as a relevant technique. We are working on automation of computations that can be applied to processing satellite imagery, computing Normalized Difference Water Index time series (in the forms of maps and annual graphs), and estimation of growing season parameters. As currently used data amounts are big (or up-to-big) geospatial data, we use the Google Earth Engine platform to process initial datasets. Our currently described experimental work incorporates investigation of the possibilities for integration of cloud computing data storage and processing with client-side data representation in universal desktop GISs. To ensure our study needs we developed a prototype of a QGIS plugin capable to run processing in GEE and represent results in QGIS.

Scalable business models for startups in renewable energy: Strategies for using GIS technology to enhance SME scaling

“…Software, GIS software provides tools and functionalities for data management, analysis, and visualization. Popular GIS software packages include Esri's ArcGIS, QGIS, and Google Earth Engine (Panidi et al, 2020). Data, GIS relies on a wide range of spatial data sources, including maps, satellite imagery, terrain models, and geospatial datasets.…”

“…Finally, it also has a version with a simple interface known as "Explorer" (https://explorer.earthengine.google.com/#workspace, accessed on 30 January 2023) for users with little experience in programming languages. Both options allow the entry of local data and the export of information for subsequent processing or visualization within geographic information systems (GIS) software, such as QGIS (Version 3.28), and ArcGIS Pro (Version 3.1.2), among others [11,12].…”
