THE GEOSPATIAL INFORMATION CENTER OF GEOCUBA, SUPPORT FOR THE USE OF SENTINEL 2 IMAGES

Abstract

The main mission of the GEOCUBA Geospatial Information Center (CIG) is to manage the institution's geospatial information internally and for society. From its conception, the foundations were established for management based on Big Data technologies and services that guaranteed high availability and performance. Once the center's infrastructure was established, work began related to the complete management of multispectral images including their storage, processing and publication in geospatial services based on ISO and OGC standards. Workflows were created that continuously download images from their source and upload them to the center's warehouse, creating the corresponding metadata that guarantees access to them. All Sentinel-2 images are available over our country with less than 60% cloud cover since January 2020, which allows various spatio-temporal analyzes to be carried out. With this infrastructure as support, a group of services have been developed using the OGC Web Processing Service standard that allows interoperability with other projects. With their use, products are generated on the maps that are used by clients. Within these products, the monthly maps with minimum clouds that have been published since January 2022 stand out.
