Map Tiler

images/download/thumbnails/57216862/mapt_ico.png

The Map Tiler plug-in builds a set of map tiles for displaying an area in high resolution. The maps are created as GeoImage (flat map) or Globe objects and placed under a low resolution map of the entire area for geographical referencing. The Map Tiler plug-in is also used for managing Pyramid object maps when used in a scene.

Note: This plug-in is located in: Plugins -> Container plug-ins -> Maps

Map Tiler Properties

Default

  • Selected Region: Defines the area of the map for which the tiles are created.

    • World: Creates tiles for the entire world.

    • Selected Map: Creates tiles for the area of the selected map in the CWMClient plug-in attached to the Map Tiler container.

    • Region List: Displays a list of regions. An item from the list can be selected to create map tiles for the selected area.

    • Long Lat: Sets the Longitude and Latitude minimum and maximum values. The map tiles are created for the defined area. When Long Lat option is selected, additional fields are enabled.

  • Map Status: Displays plug-in status messages. When configuring the tiles, the Map Status field displays the number of tiles required and tile size according to the current plug-in setup.

  • Requested Number of Tiles (2K2K): Allows the user to set the number of tiles to create.

  • Geometry Type: Selects the object type of the created tiles.

    • Globe: Creates the tiles using the Globe plug-in.

    • Flat: Creates the tiles the GeoImage plug-in.

Selected Map

  • Texture Compression: Sets the compression level for the texture (DTX5 is the highest compression level which is less texture quality).

  • Get Map Resolution/(Classic): Uses the WME Editor to zoom to the closest level you want the tiles to support. If you change the extent (in Selected Map mode) you need to set the resolution again.

Region List

  • Region Area: Selects the region you want to build tiles for.

Long Lat

  • West: Sets the Longitude value for the western edge of the map.

  • East: Sets the Longitude value for the eastern edge of the map.

  • South: Sets the Latitude value for the southern edge of the map.

  • North: Sets the Latitude value for the northern edge of the map.

Custom

The following additional parameters are available:

  • Radius/Map Size: Sets the size (in Viz units) of the globe or map tiles (all together).

  • Tessellation: Determines the number of polygons used in the object. The higher the number is, the smoother the object is drawn.

  • Texture Quality: Uses the same image resolution in the entire zoom range when set to Linear. When set to Mipmap the resolution is changed according to the distance from the image (managed automatically in Viz Artist).

  • Overlap (%): Determines the overlapping percentage for each tile.

  • Build Terrain: Builds terrain data for the created tiles.

  • Smooth Terrain: Smoothens terrain edges so they blend with the base map surface. When set to On, the Terrain Smoothing Factor is enabled.

  • Terrain Smoothing Factor: Sets the percentage of the smoothed area.

  • Terrain Height Scale: Sets the scaling factor for terrain height. The higher the factor is, the more extreme the terrain is.

  • Terrain Resolution: Sets the total terrain resolution for all tiles. A high resolution value results in a more detailed terrain (affecting performance).

Buttons

  • Build Tiles: Builds the geo-reference map and tiles.

  • Change All Maps: Builds the geographical reference map, tiles and applies style changes made in the CWMClient plug-in to all child containers (recursively) under the Map Tiler container.

  • Build Tiles (Force New): Builds the geographical reference map and tiles without checking the cache for existing maps (from the server).

  • Change All Maps (Force New): Builds the geographical reference map, tiles and applies style changes made in the CWMClient plug-in to all child containers (recursively) under the Map Tiler container, without checking the cache for existing maps (from the server).

  • Calculate Tiles Info: Calculates the tiles information, without building the tiles, and displays it in the Map Status field.
