SensLog
• SensLog is an integrated solution for sensor networks.
• SensLog consists of data model and server-side application which is capable to store, analyses and publish data in various ways.
• SensLog receives measured data from nodes or gateways, stores data properly in the database, pre-processes for easier queries if desired and then publishes data through the system of web-services.

SensLog
• SensLog is suitable for sensor networks with static sensors (e.g. meteorological stations) as well as for mobile sensors (e.g. tracking of vehicles, human-as-sensor).
• Database model was based on standardized data model for observations from OGC Observations&Measurements.

SensLog
• Main component for storing, managing and publishing sensor data
• Meeting point for measured sensor data
• Provides REST API for both sides of chain – data producers and data consumers
• Works above relation DB with spatial extension – can provide variety of analytical services
