As a whole, InfoSequia is integrated by 4 tools: 1) Operational Surveillance and Monitoring Tool, 2) Operational Hydrological Forecasting and Simulation Tool, 3) Strategic Risk Assessment Tool, and 4) Web-based Communication Tool. Originally, InfoSequia reports agricultural and vegetative drought indices based on satellite information, but if required, modelling tools (hydrological modelling, and/or dynamic system modelling) can be also coupled to the sytem to increase the capabilities to provide hydrological drought and water-scarcity indices, or drought forecasts. In its current form, InfoSequia provides drought indices which inform on the current status of greenness vegetation and land surface temperature at different timescale resolutions and spatial aggregations.
It consists of a set of fully-integrated algorithms written under an open-source multisource GIS-programming environment (Phyton, QGIS-GDAL, and R languages). The system runs on FutureWater’s computing facilities, and it depends on external “data providers” from which satellite indicators (and/or weather forecasting information) are collected. InfoSequía outputs can be deployed and delivered to clients through a shared ftp, or a Software as a Service (SaaS) (e.g. shinyapps.io. by RStudio, or HydroNET by Hydrologic). The InfoSequia programming code has been optimimally designed to be run in a fast and secure way, and to minimize runtime errors.
