The project Environmental and Crisis Information Systems (UKIS - the German abbreviation for Umwelt- und Kriseninformationssysteme) aims at harmonizing and simplifying the development of geospatial web information systems by setting up a framework of modularized and generalized software components. UKIS is divided into the open source UKIS Frontend (dlr-eoc/ukis-frontend-libraries) for the visualization of geodata on the web and a UKIS backend that provides geodata through web services and analysis functionalities. Some of these backend services are also open source.
The UKIS Frontend is a combination of multiple open source software libraries and frameworks to simplify the rapid creation of intuitive geospatial web apps. This is achieved as follows: Specification of a consistent user interface using the Clarity Design System with many UI components and styling guidelines. Web standards such as component-based development, single-page application routing, client-server communication, and tools to build, test, and update the software using the Angular development platform. Visualization of geodata using the mapping library OpenLayers, making it possible to integrate all kinds of data and standards such as those from OGC. An abstraction layer for the mapping library describes all types and interfaces, so that it is possible to integrate other mapping libraries using the same UI components. Furthermore, there are utility functions, components for map controls and tools as well as interfaces to OGC standards.
UKIS is developed at the German Remote Sensing Data Center (DFD), an institute at the German Aerospace Center (DLR). Examples of past and current developments based on UKIS are in the context of natural hazards (e.g. for floods, forest fires, tsunami), environmental monitoring (e.g. for snow cover, coastal usage, land cover), civil security (e.g. maritime surveillance, ship detection, ice monitoring), health applications (e.g. COVID-19) as well as planetary sciences (e.g. planetary geology).

Projects on stackblitz
To use the libraries in your angular application, you can either use the packaged npm modules or include this repository.
-
Use the frontend-libraries as npm modules Recommended
-
Use the frontend-libraries as npm modules (GitHub Packages) see How to install Packages from GitHub
-
or use the modules in typescript source via path mapping see Developing libraries and frontend side by side
Libraries/packages and demo applications can be found in the projects folder.
Here are a few examples:
- The OpenLayers map component
- The UI component to manage layers on a map
- Tools for the map like "mouse position" or "projection-switch"
- The angular service which handles layers (add/remove and update)
- ...
- Generate a new Angular application in the same Version like specified in our package.json @angular/core.
For this you have to install
@angular/cliin this specific Version first.
npm install -g @angular/cli@<version>
Then run:
ng new project-<name> --style=scss
- Move into the directory
cd project-<name>
- Add Clarity Angular
- See Adding Clarity to an Angular project
- If you use Clarity Core also add the icons manually
- Run the ng add command for the UKIS core-ui
ng add @dlr-eoc/core-ui --project=<appName> [options]- --routing=boolean // set up your project with routing
- for more information see core-ui ng-add
More detailed information about setting up a local UKIS application can be found in the tutorial document.
