The LuciadFusion Platform allows you to publish non-georeferenced data in a WMS service. Common examples include CAD drawings or NITF images with vector annotations. The WMS supports the use of CRS:1 for this use case.
What is a CRS:1 reference?
CRS:1 refers to a cartesian coordinate reference system with the Y-axis pointing down. The values of the X and Y-axes represent pixel coordinates. The CRS:1 coordinate reference system is commonly used for digital imagery and computer screens. Geospatial applications use this reference to represent non-georeferenced data.
Publishing data with a CRS:1 reference
You can publish data with a CRS:1 reference in a LuciadFusion WMS service. The capabilities of the resulting service will automatically list CRS:1 as supported reference. WMS clients with support for a CRS:1 reference can then request maps for the non-georeferenced data.
You can also publish data with a CRS:1 reference together with georeferenced data in a single WMS. In alignment with the WMS standard, the top layer element in
the capabilities lists the common references for all layers. If your WMS advertises both layers with a CRS:1 reference and layers with a geographic reference, this common list is empty. Instead, the child layers advertise the supported
references for their data: CRS:1 for the layers representing data with a CRS:1 reference, and geographic coordinate reference systems, such as CRS:84 or EPSG:4326, for the layers representing data with a geographic reference.
You can configure fhe full list of coordinate reference systems supported by the WMS in
the config/fusion.common.yml file.
