This library bundles our clients for OGC standards.

WPS

This is a client to communicate with WPS-servers. With it, remote procedures can be called, their status monitored and their results fetched. The service is intended to abstract away the differences between the versions of the WPS protocol. It currently supports both WPS 1.0.0 and WPS 2.0.0.

const c = new WpsClient('1.0.0', httpClient);
const exec$ = c.execute('http://testserver.com/wps', 'processId', inputs, outputDescriptions);
exec$.subscribe(results => console.log(results) );

OWC

This is a parser to read from / write to OWC files. OWC can be used to share information about a map-context (such as extent, visible layers, zoom, ...) across multiple clients. This parser converts to / from UKIS-specific datatypes, like UKIS-rasterlayers, UKIS-vectorlayers etc. The OWC format is written to be easily extendable. We made use of this capability by adding some UKIS-specific semantic information - this information is encoded in the interfaces found in the file eoc-owc-json.ts.

Jsonix

Parts of this library depend on jsonix. The current version of jsonix (3.0.0) does not build to ES2015. To still be able to use this library, we created a fork with some minor modifications. As soon as the main repository of jsonix has fixed its build problems (we're working on a pull-request) we can move from our fork back to the main repo.

===

This library was generated with Angular CLI version 8.2.14.

Code scaffolding

Run ng generate component component-name --project services-ogc to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module --project services-ogc.

Note: Don't forget to add --project services-ogc or else it will be added to the default project in your angular.json file.

Build

After building your library with ng build services-ogc, go to the dist folder cd dist/services-ogc and run npm publish.

Running unit tests

Run ng test services-ogc to execute the unit tests via Karma.

Further help

To get more help on the Angular CLI use ng help or go check out the Angular CLI README.

Changelog

7.1.0 (2020-06-03) (Schematics, OL-configuration, performance-monitoring)

Features

• @dlr-eoc/core-ui: add tests for schematics to CI
• @dlr-eoc/core-ui: Provide header component from core-ui module
• @dlr-eoc/map-ol: Allow to pass OpenLayers options to IMapControls
• demo-maps: Added new component performance, that measures FPS and change detection.
• demo-maps: Added new route map7 that showcases drop in performance when displaying large vector datasets.
• demo-maps: Added service LargeLayersService that allows users to load data from a WFS with a specified data-strategy (downloading full data, downloading only current viewport, using simplified geometry, not loading any properties) to compare how each strategy affects loading- and render-performance.

Refactoring

• @dlr-eoc/core-ui: on ngAdd without routing setup a view component so not all code is placed in the App component - this

• @dlr-eoc/core-ui: Start convert clr-theme to use custom css properties. If you must support IE11 see Setting up IE11 support.

• @dlr-eoc/services-layers: Type for CustomLayer (type: 'custom') now optional on creation

• demo-maps: Add more examples how to use CustomLayers for OpenLayers route-example-custom-layers

• @dlr-eoc/map-ol:

  • Overview-Map Control now as default uses a Clarity Icon
  • Prepare for OpenLayers Types with ol@dev
  • Start to use custom css properties

Bug Fixes

• demo-maps: workaround for header overflow #6

• @dlr-eoc/layer-control: Layerentry expand icon not working in Edge Browser due to [dir].

• @dlr-eoc/map-ol:

  • Fix Bug Attribution Control is displayed twice Issue #3
  • Fix Bug Issue #1 Layer Popup now working for BaseTile, BaseImage, BaseVector (Cluster, Vector, VectorTile)

• @dlr-eoc/core-ui: Use the same types for 'ts' as @schematics/angular /**Types of property 'kind' are incompatible */

• @dlr-eoc/services-ogc:

  • Used to depend on @boundlessgeo/jsonix, because this fork of @highsource/jsonix worked with angular8. However, that fork declared a couple of variables globally, which now no longer works with angular9 and the ES2015 target.
  • Created an own fork under @michaellangbein/jsonix that adresses both the global variables issue and allows building to es2015.
  • All imports of 'jsonix' have been updated to '@michaellangbein/jsonix'
  • As a consequence of using this package, the sourceIsEvt hack in src/index.html is no longer required and has been removed.
