chop.py

[http://addons.silentwings.no/index.php?module=Downloads&func=view&cid=3 chop.py] is a Python script that chops up a GeoTIFF (georeferenced TIFF image) into a grid of equal size pieces. 
This is particularly useful if you need to touch up a large aerial or satellite image in a graphics application such as GIMP or Photoshop and one doesn't have enough RAM for the entire image to fit into. 
chop.py uses utilities from the [http://www.gdal.org/ GDAL] library which must be installed.

chop.py has two basic modes of operation : size and pieces.

To chop an image into pieces with each piece having a maximum size of 5000 by 4000 pixels :
chop.py -s 5000 4000 input.tif output.tif

To chop an image into 2 horizontal by 4 vertical pieces :
chop.py -p 2 4 input.tif output.tif

If you would like to create TIFF World files for the output images pass the -t or -tifw program argument. That will ensure that when you modify and save the images in an application that doesn't honor the georeferencing tags (such as GIMP and Photoshop) the georeferencing information will not be lost.

If you would like the pieces to have an overlap so that they can be seamlessly mosaiced back together again you can specify the overlap in pixels with the -o or --overlap program argument.

Full example with maximum piece size of 3000 by 3000 pixels, 10 pixel overlap between pieces and TIFF World file creation :
chop.py -s 3000 3000 -t -o 10 input.tif output.tif

File & Directory Structure

This article describes the file and directory structure used to store Silent Wings scenery.

[[Image:File_structure_1.png|none|thumb|Minden scenery directory]]

There is one master directory that holds all the files required for a scenery area. The name of the master directory is the name the user will see in the user interface when they want to select the scenery.
The icon for the scenery, the waypoints list and a set of scenery blocks are placed inside the master scenery directory. The tasks.dat file contains the saved tasks a user has created and will be created automatically by the user interface. It is not required at all for scenery creation and shouldn't be shipped with a scenery release.

The scenery block directories (BLK*) contain the terrain and 3D models.
Scenery may consist of just one block or multiple blocks that are tiled to cover a larger area.
Each scenery block contains :

* 3D models and their textures in the models directory (models and models/textures)
* terrain textures in the textures directory
* a list of the airports in the block in the airports.dat
* the elevation data in a file called terrain.tin (triangulated irregular network)
* the rest are configuration/control files

Nearly all of the files in the BLK directories are created automatically by the scenery tools with the exceptions being :

* default model textures
* custom 3D models
* forest models, textures and config files

Below is an example of the Minden scenery file structure.

There is one master directory that holds all the files required for a scenery area. In this case it's called "minden" and this is the name the user will see in the user interface when they want to select the scenery.
