To connect to an LTS service from LuciadRIA, you need to know the endpoint URL of the service, the coverage ID, and the coverage parameters.

Find out the endpoint URL

To find out what the endpoint URL is, go to the SERVICES tab in LuciadFusion Studio. Click the title of the LTS service in the list to open the details screen, and find the ENDPOINT URL entry.

Find out the coverage ID

If you are using LuciadRIA 2019.1 or a more recent version, you can create an LTSCapabilities instance from the endpoint URL to find the coverage ID.

If you are using LuciadRIA 2019.0 or an earlier version, you must get the coverage ID from LuciadFusion Studio. To find it, click the PRODUCTS tab in the details screen of the LTS service. Click the product for which you want to get the coverage ID.

Figure 3. The product/coverage ID

For most products, you can find the coverage ID by looking at the address bar of your web browser: everything after products/ is the product ID, and therefore also the ID of the coverage.

Find out the product ID of an existing coverage

If the product is created from an existing coverage, LuciadFusion re-uses the ID of the existing coverage for the new coverage. In that case, you must find out the coverage ID in another way.

To determine the coverage ID, click the PRODUCTS tab in the details screen of the LTS service, and click the coverage product to open its product details screen.
Next, click the single data entry at the bottom of the product details screen. The details screen for the product data opens.

Find out which XML file to open for the coverage ID

If the FORMAT entry equals FusionCoverage, you can find the coverage ID by opening the XML file specified in the PATH entry in a text editor and inspecting the value of the id attribute present on the root element.

Find the coverage parameters

The Table 1, “Coverage parameters” table lists the parameters of a coverage generated in a LuciadFusion pre-processing job for an LTS service. The parameters are optimized for consumption by LuciadRIA.

You can also connect to the LTS service from a LuciadLightspeed application or from Lucy. Keep in mind that these coverage parameters were optimized for LuciadRIA.

Load in LuciadRIA

Now that you have the endpoint URL and coverage ID, you can load the data in LuciadRIA. Follow this tutorial to learn how to visualize LuciadFusion coverages in LuciadRIA.
