Converting Raster to MPT with Resolution Pyramid
Convert selected raster files, which do not include resolution levels or have an insufficient number of them, to stream-optimized MPT files with resolution pyramids.
To display a layer in different altitudes, TerraExplorer Pro requires a number of resolution levels per layer, which are also known as a resolution pyramid or a multi-resolution file. Without a resolution pyramid, the layer will not be displayed when attempting to zoom out from the original resolution level.
A layer source file may or may not include resolution levels or may have an insufficient number of them. In that case, TerraExplorer can generate a resolution pyramid for such sources. The resulting MPT file replaces the original layer source file and does not point to it.
Note: It is good practice to convert all layers in the project to MPT with a resolution pyramid.
Convert Raster to MPT with Resolution Pyramid Dialog
To convert a raster layer to an MPT with a resolution pyramid:
1. In the Project Tree, select the layers that require a resolution pyramid.
2. On the Layers tab, in the Raster group, click Raster to MPT. The Convert Raster to MPT with Resolution Pyramid dialog is displayed.
3. Select the check boxes of the layers for which to create a resolution pyramid.
4. Click Convert. When the creation process is finished, the Pyramid Status column changes to “Done”.
Note: If you want to cancel the resolution pyramid creation in the middle of the process, click Abort.
