BigMap 2

This is a successor to BigMap script: a tool to stitch map tiles and produce a PNG image. Among improvements are:

Better landing page with Leaflet and URL parsing.
More than fifteen popular tile layers to choose from.
KML, WLD and OziExplorer MAP meta files generation.
Map downloading script can be produced in Python language.
Fixed user agent and small pauses while downloading.
Attribution on generated images.
Server-side stitching with a queue.

Installation

The following directory structure is recommended:

Path	Mode	Description
`./`	`0755`	Place scripts from `scripts` directory here, with `0755` mode on them.
`./queue/`	`0777`	Working directory that should be outside wwwroot.
`./queue/tasks/`	`0777`	Task files will be put here by PHP scripts.
`./queue/queue`	`0666`	A queue file that will be modified by PHP scripts.
`./www/`	`0755`	WWWRoot. Place PHP scripts here and point HTTP server to it.
`./www/result/`	`0777`	A directory for generated image files.

Then modify paths to be absolute in bigmap_download.pl and purge_images.pl scripts, so they can be called by cron. Also change server address in bigmap_download.pl and size limit in purge_images.pl. And add those two lines in crontab -e editor (your intervals may vary):

*/2 * * * * /var/www/.../bigmap_download.pl
2 */6 * * * /var/www/.../purge_images.pl

Of all PHP scripts only queue.php needs configuring: you should change e-mail in there, and may want to alter limits. Tile limit is specified in $max_tiles variable in bigmap.php.

After changing tiles.txt you would want to update Leaflet layers in index.html. To do this, just check paths in scripts/tiles2html.pl and run it.
