Luciad Developer Platform

The LuciadCPillar API offers a raster model base class. It’s impossible to implement this base class directly, but you can create instances of it in a couple of ways:

By using a model decoder. Model decoders can create a raster model, for example by decoding files encoded in a certain format, or by using a standard that uses HTTP. These are examples of model decoders:
- GdalModelDecoderGdalModelDecoderGdalModelDecoder: to decode GeoTIFF data
- GeoPackageModelDecoderGeoPackageModelDecoderGeoPackageModelDecoder: to decode GeoPackage raster data
- WmsModelDecoderWmsModelDecoderWmsModelDecoder: to decode data using the OGC WMS protocol
- WmtsModelDecoderWmtsModelDecoderWmtsModelDecoder: to decode data using the OGC WMTS protocol
By using a raster model builder. When there is no model decoder available for your raster data, or when you want to add a non-referenced image to the map, you can use one of these model builders:
- MultilevelTiledRasterModelBuilderMultilevelTiledRasterModelBuilderMultilevelTiledRasterModelBuilder: allows you to define several detail levels, and a tiling grid for each level. You can also configure a data retriever data retriever data retriever that can return the actual data for each of the tiles.
- QuadTreeRasterModelBuilderQuadTreeRasterModelBuilderQuadTreeRasterModelBuilder: similar to MultilevelTiledRasterModelBuilderMultilevelTiledRasterModelBuilderMultilevelTiledRasterModelBuilder, but it allows you to define a quad tree raster structure more easily.

These tutorials shows how you can provide your own raster data:
