Water Map Export

[Craig]

Hi All

Just wondering if the following options exist as I can't find them:

1. Export the Water Map without the auxiliary data.
2. Export the Water Map as an HFF mosaic.
3. Export the Water Map as an WMF mosaic in single float format.

cheers

Found it: atConvertWaterToHeight plugin

Hi Craig,

Thanks for the questions.

1. Export the Water Map without the auxiliary data.

A water map file (WMF) without the auxiliary data would be a heightfield file (HFF)*; see answer #2 for how to export the water map as a HFF.

2. Export the Water Map as an HFF mosaic.

As you've already found, the 'atConvertWaterToHeight' plugin is your best bet. This option allows you to select the water types to be included in the heightmap (sea, lakes, water table and/or shore lines).

If you just want a straight HFF export of the water map (including all water bodies and the water table), you can also use the following procedure:

1. Select 'File->Export->Export map' from the menu.
2. In the 'Select map to export' dialog box, select 'water map'.
3. In the 'Export map' wizard pane, enable the 'Split map into tiles (mosaic map)' checkbox.
4. Set the filename of the mosaic using the browse button.
5. Click 'Next' to proceed to the 'Mosaic settings' wizard pane.
6. Select 'HFF' from the format drop-list, and set your desired tile size.
7. Click OK to export the water map as a HFF mosaic.

This method is probably the most direct way to "Export the Water Map as an HFF mosaic", but is probably less useful since it includes the water table, which most users don't want.

3. Export the Water Map as an WMF mosaic in single float format.

32-bit floating point mode is included in the WMF specification for completeness but is not enabled in L3DT because 16 bits of precision are more than adequate for the purpose of storing water height data.

Best regards,
Aaron.



* Well, not strictly true. Their file headers differ by a few bytes. Nonetheless, the difference is insufficient to require a new mode in WMF given that the same functionality is supported by HFF.
