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

SensLog VGI extension• Stores VGI observations from web and mobile
applications• Attributes of VGI observations not only simple
datatypes but multimedia files too• Few mandatory attributes, optional according to
users needs with only small limitation on data volume
