tools for a sensor observation service based client

npm version

This project contains Angular based Modules, Components, Injectables to build a sensor observation service based client.

Description

Tools for Building Web Applications

Providing Reusable Components for Building (Sensor Web) Client Applications

52°North created the Helgoland Toolbox to facilitate the reuse of developments for Sensor Web client applications. It provides a range of modules that offer functionalities for building Web applications dealing with dynamic spatio-temporal data. The Helgoland Toolbox modules are used to build the 52°North Helgoland Sensor Web Viewer. Additional applications (e.g. the BelAir app, smle, or the developments resulting from the TaMIS project) are also built upon this library.

Features:

The most important functional modules comprise:

Core

  • Communication with the APIs (Helgoland API and OGC SensorThings API)
  • Important common services (local storage, time)
  • Central interfaces and abstract classes

Caching

  • Request Caching with Angular Interceptors

d3

  • Trajectory Graph component
  • Time Series Graph component

Depiction

  • Legend entries
  • Table view of data

Map

  • Controls (Geo-Search, Locate, Zoom, Extent)
  • Map Selector component

Selectors

  • List Selector for observation data
  • Service Selector for data sources.

The work on the Helgoland Toolbox focused on improving Helgoland Toolbox’s support of the OGC SensorThings API standard. A dedicated layer to improve the abstraction of underlying data sources enables the Helgoland Sensor Web Viewer to consume data directly from OGC compliant SensorThings API instances as well as connect to the 52°North Helgoland API. Research covered experimenting on how to achieve the integration of access-controlled data sources and incorporation of near-real time data streams via MQTT. For this purpose, we developed a dedicated dashboard for visualizing research vessel tracking data based on our toolbox. This development was part of the EMODnet Ingestion 2 project.

Key Technologies:

Benefits:

  • Reusable components for building client applications
  • Modules for visualizing different types of sensor data (time series, trajectories, profiles)
  • Mapping modules
  • Different components for data selection

Quick Start

Dependencies

Node/NPM

Install latest Node and NPM following the instructions. Make sure you have Node version ≥ 10 and NPM ≥ 6. brew install node for Mac.

Installing

  • fork this repository.
  • clone your fork to your local environment.
  • npm install to install required dependencies.

Build the libraries

  • npm run lib:build for building the library once

Other commands

Lint the complete code

  • npm start will start the test application, which provide views for the main modules and components
  • the app, and their corrensponding files can be found in the src folder

See Documentation

References

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

Development

  • different moduls are in the projects folder

use customized toolbox in an other app development

build Toolbox

  • npm run lib:build builds the complete toolbox in the dist-folder
  • after build npm run lib:pack packs every module to a file in the following structure helgoland-MODULENAME-CURRENT_VERSION.tgz in the root-folder
  • every packed module can be used by installing it in app development with it's relative path, for example npm install ../helgoland-toolbox/helgoland-MODULENAME-CURRENT_VERSION.tgz

Other commands

Run tests

  • all implemented tests for the modules can be run by npm test

Lint the complete code

  • ng lint for performing static code analysis.

Generate documentation

  • npm run compodoc for generating documentation locally
  • npm run gh-pages for generating documentation and uploading it to GitHub Pages
Bump library version

Troubleshooting while using this library

  • add allowSyntheticDefaultImports: true to your tsconfig.json to avoid error messages like ... has no default export
  • don't forget to add styles of nested dependencies
