Introduction

As we approach the end of the exciting 13 week period of the Google Summer of Code, our proposed project wps-ng has successfully fulfilled the expectations we had set forth in the beginning. With our new Client Library deployed on NPM (wps-ng), the future angular clients using this library will be able to employ standard OGC Web Processing Services along with the numerous benefits of Typescript’s static typing. We also developed a client to demonstrate the library use case and serve as a boilerplate starter for Angular projects.

Introduction

The main goal of developing the Angular WPS Client Library was to support developers creating new WPS clients in Angular by making the library easy to import and use. The developers will know in adavance the Type information of the request & response objects exchanged with the WPS server since Typescript is a statically typed language. Another benefit of creating this WPS library in angular is the IDE friendliness with features such as Auto-completion and Compile Time Error detection.

In this Google Summer of Code 2020 project, we propose to build a new Web Processing Service (WPS) client named wps-js-ng written in the Angular 9 framework with module classes written in typescript. It will be an extension to the 52°North’s wps-js project, which provides encoding and parsing of the basic WPS Requests/Response (such as GetCapabilities, DescribeProcess, Execute, GetStatus and GetResult). This new client will conform to the latest OGC WPS 2.0 standards and is mainly targeted for clients using Angular programming language, who can simply import the library and have all the model classes and modules generated by running simple angular commands.

Javascript is a very popular programming language. Once started to make web sites more dynamic, it has grown into a powerful and fast language, with several runtime environments (client- and server-side!), and support for procedural, functional, object-oriented, and modular programming paradigms. How cool is that? Moreover it is easy to learn and the basics are very simple. But most importantly, it can be executed by any web browser today! Therefore it naturally is used widely also in 52°North communities, and the Sensor Web community is no exception. However, for many good reasons, the existing Sensor Web browser client utilizes Google Web Toolkit (GWT), which compiles Java to browser-specific Javascript, and utilizes server side rendering.

But wait, today you will find an alternative to explore time series data from the standardized Sensor Observation Service (SOS): SOS.js.more >
