The LuciadRIA contains two types of raster models:

  • RasterTileSetModel instances. These models are capable of downloading multi-leveled, tiled raster data to the browser, so that they can be visualized on a map.

  • RasterImageModel instances. These models also download raster data to the browser for visualization, but the raster data consists of images of arbitrary sizes and scales instead of tilesets.

Both models and their use cases are explained in more detail below.

RasterTileSetModel

A RasterTileSetModel is the client-side representation of a potentially large, tiled, multi-level image dataset. LuciadRIA raster data consists of square tiles. Each subsequent raster level offers more detail and quadruples the number of tiles: one tile on level n is represented by 4 tiles on level n+1.

This type of model is used for data such as:

  • LuciadFusion coverages

  • WMS raster data

  • Bing Maps raster data

RasterImageModel

A raster image model is similar to a RasterTileSetModel. However, instead of providing access to images as pre-defined tiles, it provides access to images of arbitrary size and scale.

This type of model is for example used for:

  • Google Maps Data

  • WMS raster data

You cannot create your own RasterImageModel.

RasterImageModel instances are not yet supported on WebGL Maps.
