Description

Web-Based Visualization of Observation Data

Enabling exploration, analysis and visualization of sensor web data

This lightweight web application enables the exploration, visualization and analysis of sensor web data in various fields of use, e.g. hydrology, meteorology, environmental monitoring, traffic management. You can:

  • explore stations or mobile sensor platforms in a map
  • select time series data by a list selection
  • visualize and navigate through time series data, trajectory data, profile measurements
  • create favorites of selected time series
  • export visualized data as CSV files.

The application can connect to different Sensor Web endpoints (via the 52°North Helgoland API). These endpoints provide a thin access layer to sensor data (e.g. offered by SOS servers'databases) via RESTful Web binding with different output formats. In addition to the Sensor Web endpoints, the Viewer can also connect to different OGC SensorThings APIs.

This software component is based on the Helgoland Toolbox. It integrates the different toolbox modules into a viewing applications that can be easily customized to the requirements of specific users.

Features:

  • access to SOS instances via REST-APIs (supports OGC SOS spec...)
  • diagram view of multiple time series, temporal zooming & panning...
  • data export (CSV)

Key Technologies:

Benefits:

  • Lightweight, web-based visualization of observation data
  • Exploration of Sensor Web data sources (SOS, SensorThings API)
  • Support of different types of obsevation data (time sereis, trajectories, profiles)
  • Data download (CSV)

Quick Start (Configuration)

Download the latest version of Helgoland.

  • Deploy the war-file of the client in your favorite web container (e.g. tomcat)
  • Or a war-file can be build with the command npm run bundle-war of the current development
  • Deploy as a static web page in a web server (e.g. apache)

Configure your client in the settings.json in the root folder. Check this(link) site for the different configuration parameter in the settings.json. The main parameters are:

  • defaultProvider - this is the default selected provider, when the user starts the client
  • datasetApis - this is a list of all supported providers by the client

References

The software is in operational use by the following organizations or within the following projects.
