**LIVE DEMO:**

- ČÚZK: [http://osm.zby.cz/tiles_cuzk.php/17/70788/44404.test](http://osm.zby.cz/tiles_cuzk.php/17/70788/44404.test)

## Config

First lines of the PHP script itself

    // we log the execution time

    $time_start = microtime(true);

    

    // url of WMS image query ending with bbox=

    $wmsurl = "http://wms.cuzk.cz/wms.asp?...&BBOX=";

    

    // filetype of WMS - png or jpg --> this one is saved and conversion to .jpg/.png is possible

    $filetype = 'png';

    

    // sql table name

    $table = "tiles_cuzk";

    // db login

    mysql_connect("localhost", "root", "") or die("Could not connect to db");

    mysql_select_db("test") or die("Could not select db");


You are supposed to create the MySQL table:

    CREATE TABLE `$table` (

      `z` tinyint(2) unsigned NOT NULL,

      `x` int(10) unsigned NOT NULL,

      `y` int(10) unsigned NOT NULL,

      `hits` int(10) unsigned NOT NULL,

      `hits_month` int(10) unsigned NOT NULL,

      `hits_last_month` int(10) unsigned NOT NULL,

      `downloaded` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,

      `calculated` tinyint(4) NOT NULL,

      `image` blob NOT NULL,

      PRIMARY KEY  (`z`,`x`,`y`)

    )

Example sizes for ortophoto map:

    z16 = 870 000

    -> jpg 12 GB

    -> png 43 GB

    

    z15 = 200 000

    -> jpg 2.8 GB

    -> png 10.0 GB

    

    z14 = 50 000

    -> jpg 0.7 GB

    -> png 2.5 GB 

    

    z13 = 13 000

    -> jpg 182 MB

    -> png 650 MB
