COBWEB Sensor Data Viewer (beta)


COBWEB Sensor Data Viewer logo


The COBWEB Sensor Data Viewer (beta) provides a variety of ways of accessing environmental data created by and relevant to the COBWEB project. 

Data presented in the Viewer is gathered from a wide range of sources which include crowd sourced data collected by researchers and citizen scientist using the COBWEB app, on-site sensors such as the weather stations set up by COBWEB in the Dyfi Biosphere, third party Web Map Services and Web Feature Services, and cyber-sensors. A full list of sensors and services used is provides below.

Built upon the Leaflet and OpenStreetMap APIs, the Viewer has been created to provide both worldwide coverage and biospheres of interest to the COBWEB project. Specifically, the Dyfi Valley, Samaria Gorge, Mount Olympus and the Wadden Sea.

Web Map Services overlays are acquired from the OpenWeatherMap API providing information on:

  • Precipitation
  • Cloud Coverage
  • Wind
  • Pressure
  • Snow

Cyber sensors gather relevant environmental data from social media sources such as twitter and Flickr.

Real-time earthquake data gathered from the U.S. Geological Survey.

In-situ sensor data:

  • Dyfi Valley peat bog data monitoring water depth levels, pressure (mBar), pressure (PSI), and temperature
  • Dyfi Valley salt marsh data monitoring pressure (mBar), temperature (°C), depth (m), adjusted Depth (cm), actual Conductivity (µS), specific Conductivity (µS), salinity (PSU), dissolved Solids (ppt), resistivity (phm-cm) and water Density (g/cm)
  • Real-time weather data from Davis Weather stations deployed as part of the cobweb project
  • The Shoothill Environmental Data API which provides river level data

Citizen Observation Data which is gathered using the COBWEB app focusing on:

  • Japanese Knotweed
  • Flooding

New features will be added to the Viewer as the COBWEB project evolves.
