Work with data

Tools developed within CitiObs to turn data collected by citizens into reliable, usable information. They help you organise and share data using open standards, check and correct its quality, and explore it on maps and charts, from single sensor readings to air quality maps of Europe.

• Data tool

  Air Quality Mapping at European Scale

  The sMESH model (Satellite and ML-based Estimation of Surface air quality at High resolution) is a machine-learning framework that downscales regional air quality forecasts to estimate daily (and in some implementations hourly) surface PM₂.₅ concentrations over Europe at ~1 km resolution, producing high-resolution maps that support analysis and policy applications.
• Data tool

  Browser-based visualization tool

  TAPIS is a simple, browser-based tool developed within the CitiObs project to help communities and Citizen Observatories easily visualize their data.
• Data tool

  CitiObs Data Assistant

  An AI-powered assistant that helps citizens, researchers and city authorities explore and understand citizen-science environmental data.
• Data tool

  CitiObs Decision Support System (DSS)

  CitiObs has developed a web-based dashboard to display validated and interoperable data.
• Asynchronous messaging

  Gaxnet (little hook) on IIS

  A C++ implementation of a WebHook subscriber compatible with Windows IIS Native Code. This tool implements a server that dialogues WebSocket from a web page and client that dialogue with a WebHub that implementing a W3C WebSub.
• Asynchronous messaging

  MiraMon

  The MiraMon Web Application displays the historical sensor reading and updates the chart based on new data received via STA-WebSub
• Citizen Science with STAplus

  PMScan mobile app

  CitiObs PMScan mobile app captures air quality with the wearable sensor PMScan and uploads the data to a STAplus service.
• Citizen Science with STAplus

  QGIS SCK plugin

  The QGIS SCK plugin allows to record air quality with the sensor from the Smart Citizen Kit from IIAC using the QGIS desktop application
• Data tool

  Quality Control and Data Validation Tool

  FILTER (Framework for Improving Low-cost Technology Effectiveness and Reliability) is a quality control and correction system for PM2.5 static low-cost sensor networks, PM2.5 mobile/wearable measurements and noise measurements.
• Asynchronous messaging

  See the last value in TAPIS

  The 'last value receipes' illustrates how to monitor a variable capture by a particular party. The way this is done, is conditioned by the STAplus entities data model (see the figure below) that relates Observations to Party through Datastream.
• STAplus standard

  STA DGGS

  OGC 26-057 adds a Cell entity so observations can be grouped into Discrete Global Grid System zones and aggregated.
• Citizen Science with STAplus

  STA DGGS plugin implementation

  The STA-DGGS plugin implements the STA-DGGS Standard. The plugin can be deployed with the Fraunhofer FROST-Server framework which is the open source reference implementation for the OGC SensorThings API.
