MapBoxComposer

This is the home of a small script that will allow you to compose and stick images from a MapBox created image.

Purpose

Initially the whole purpose of this was to fix a small problem I saw with a website. The awesome people at Tele Geography created a interactive version of their [Submarine Cable Map] (http://www.telegeography.com/telecom-maps/submarine-cable-map/index.html). The only problem was that it was extremely slow to load tiles when zoomed in at any level. After countless minutes of frustration I decided to try and reverse engineer the whole thing to download the images and compose them myself for fast browsing. The result is this set of scripts that you see here.

Future

In the future the plan is to expand this to compose any interactive map or image that uses the MapBox.

This is a work in progress...

Files Purpose

DownloadTiles.py

Generates a Makefile that will use wget to download the tiles using the original folder structure.

Makefile

Downloads all the tiles based on the instructions set in DownloadTiles.py

The whole purpose of this is to speed up the process and make it more realistic to the server just in case. Additionally its extremely fast to do so in parralel using the -j flags.

FixFilenames.py

When using any * completion the shell will detect 2 as being larger than 10, because its a string comparison. Since the server gives me the files as 1 and not 01, this script fixes this issue.

StichFolder.py

This script will run through each folder and do the vertical stiching required to join all the images.

TODO: As soon as all the vertical stiching is done then do the horizontal stiching.
TODO: Since each folder is completely independent from each other and the whole process takes long then we should turn it into a Makefile and use the -j flag or make it parallel in some other way.
