+=================================================
+TileServer PHP - OGC Web Map Tiling Server (WMTS)
+=================================================
 
-Easy to install OGC WMTS compliant map tile server for pre-rendered maps made with MapTiler / TileMill / MBTiles
+This server distributes maps to desktop, web, and mobile applications from
+a standard Apache+PHP web hosting.
+
+It is a free and open-source project implementing OGC WMTS standard for
+pre-rendered map tiles made with [MapTiler](http://www.maptiler.com/), GDAL2Tiles,
+or available as MBTiles files.
+
+It is the easiest and cheapest way how to serve zoomable maps in a
+standardized way - practically from any ordinary web hosting.
+
+It is easy to install - just copy the project files to a PHP-enabled
+directory along with your map data containing metadata.json file.
+
+It comes with an online interface showing the list of the maps and step-by-step guides for desktop GIS software:
+
+![tileserver-screenshot](https://f.cloud.github.com/assets/59284/1041807/a040160c-0fdb-11e3-8941-ab367b2a648d.png)
+
+This project is developed in PHP, not because it is the best language for
+development of web applications, but because it maximally simplify the
+deployment on large number of web hosting providers including various free
+web hostings.
+
+Tiles are served directly by Apache with mod_rewrite rules as static files
+and therefore are very fast and with correct HTTP caching headers.
+Only XML metadata are delivered via PHP.
+MBTiles are served via PHP, unless they are unpacked with mbutil.
+
+Requirements:
+-------------
+
+- Apache webserver (with mod_rewrite / .htaccess supported)
+- PHP 5.2+
+
+(or anther webserver implementing mod_rewrite rules and PHP)
+
+Installation:
+-------------
+
+Download the project files as a zip archive or source code from GitHub and
+unpack it into a web-hosting of your choice.
+
+If you access the web address relevant to the installation directory, 
+the TileServer.php Server should display you a welcome message and further
+instructions.
+
+Then you can upload to the web hosting your mapping data - a directory with
+tiles rendered with [MapTiler](http://www.maptiler.com/).
+
+Tiles produced by open-source GDAL2Tiles or MapTiler and tiles in .mbtiles
+files can be easily converted to required structure (XYZ with top-left origin
+and metadata.json file).
+
+The OpenSource utility mbutil (https://github.com/mapbox/mbutil) produces
+exactly the required format.
+
+Direct reading of .mbtiles files is supported, but with decreased performance
+compared to the static files in a directory. Therefore the data management,
+especially upload over FTP or similar protocols, is easier.
+
+Supported protocols:
+--------------------
+
+- OpenGIS WMTS 1.0.0
+  
+  The Open Geospatial Consortium (OGC) Web Map Tile Service (WMTS)
+  Both KVP and RESTful version 1.0.0:
+  http://www.opengeospatial.org/standards/wmts/
+  
+  Target is maximal compliance to the standard.
+  
+  Exposed at http://[...]/wmts
+  
+- OSGeo TMS 1.0.0
+
+  The OSGeo Tile Maps Service, but with inverted y-coordinates:
+  http://wiki.osgeo.org/wiki/Tile_Map_Service_Specification
+  This means request compatible with OpenStreetMap tile servers.
+
+  Target is "InvertedTMS" implementation used by the ArcBruTile client
+  which is available from http://arcbrutile.codeplex.com/ and uses
+  flipped y-axis.
+
+  Exposed at http://[...]/tms
+  
+- TileJSON.js
+
+  Metadata about the individual maps in a ready to use form for web
+  clients following the standard http://mapbox.com/developers/tilejson/
+  and with support for JSONP access.
+
+  Exposed at http://[...]/layer.jsonp
+  
+- Direct access with XYZ tile requests (to existing tiles in a directory
+  or to .mbtiles)
+
+  Compatible with Google Maps API / Bing SDK / OpenStreetMap clients.
+  
+  Exposed at http://[...]/layer/z/x/y.ext
+  
+- MapBox UTFgrid request (for existing tiles in .mbtiles with UTFgrid support). Callback is supported 
+
+  Example https://www.mapbox.com/demo/visiblemap/
+  Specification https://github.com/mapbox/utfgrid-spec
+  
+  Exposed at http://[...]/layer/z/x/y.grid.json
+  
+
+To use the OGC WMTS services point your client (desktop or web) to the URL
+of 'directory' where you installed tileserver.php project with suffix "wmts".
+
+For example: http://www.example.com/directory/wmts
+ 
+You can also install the project into a root directory of a virtual server:
+Then the address is: http://www.example.com/wmts
+
+Similarly for another end points.
+
+The supported WMTS requests includes:
+
+GetCapabilities RESTful/KVP:
+ 
+   http://[...]/1.0.0/WMTSCapabilities.xml
+   http://[...]?service=wmts&request=getcapabilities&version=1.0.0
+ 
+GetTile RESTful/KVP:
+ 
+   http://[...]/layer/[ANYTHING-OPTIONAL][z]/[x]/[y].[ext]
+   http://[...]?service=wmts&request=getTile&layer=[layer]&tilematrix=[z]&tilerow=[y]&tilecol=[y]&format=[ext]
+   
+Another example requests are mentioned in the .htaccess.
+
+Performance from the web clients
+--------------------------------
+
+It is highly recommended to map several domain names to the service, such as:
+http://a.example.com/, http://b.example.com/, http://c.example.com/.
+This can be done with DNS CNAME records pointing to your hosting.
+The reason for this is that traditionally browsers will not send more then two
+simultaneous http request to the same domain - with multiple domains for the
+same server you can better saturate the network and receive the maps faster.
+
+Performance
+-----------
+
+In case the data are available in a form of directory with XYZ tiles, then
+Apache webserver is serving these files directly as WMTS RESTful or KVP.
+
+This means performance is excellent, maps are delivered very fast and large
+number of concurrent visitors can be handled even with quite a low-end
+hardware or cheap/free web hosting providers.
+
+Mod_rewrite rules are utilized to ensure the HTTP requests defined in the OCG
+WMTS standard are served, and Apache preserve standard caching headers & eTag.
+
+The performance should be significantly better then performance of any other
+tile caching project (such as TileCache.org or GeoWebCache).
+
+Performance graph for "apache static" comparing other tile caching projects
+is available online at:
+http://code.google.com/p/mod-geocache/wiki/PreliminaryBenchmark
+
+Limits of actual implementation
+-------------------------------
+
+With intention, in this moment the project supports only:
+- Mercator tiles (a la OpenStreetMap) and Geodetic tiles (WGS84 unprojected)
+  with known and described tiling scheme.
+- All tiles must be 256x256 pixels.
+- We enforce and require XYZ (top-left origin) tiling schema (even for TMS).
+
+Password protection
+-------------------
+
+HTTP Simple Authentication can be easily added to the server.
+Edit the .htaccess and add these lines:
+
+AuthUserFile /full/path/to/.htpasswd
+AuthType Basic
+AuthName "Secure WMTS"
+Require valid-user
+
+Create a file called .htpasswd with user:password format.
+You can use a command-line utility:
+
+$ htpasswd -c .htpasswd [your-user-login]
+
+Or an online service:
+
+http://www.htaccesstools.com/htpasswd-generator/
+
+HTTPS / SSL support
+-------------------
+
+TileServer.php can run without any problems over HTTPS, if required.
+
+Microsoft Windows web-hosting
+-----------------------------
+
+The TileServer.php should run on Windows-powered webservers with Apache
+installation if PHP 5.2+ and mod_rewrite are available.
+
+With the IIS webserver hosting, you may need PHP and IIRF module
+(http://iirf.codeplex.com/) and alter appropriately the rewrite rules.

+This server distributes maps to desktop, web, and mobile applications.

+Please modify 'tileserver.php' file and replace the '<?php echo $baseUrl ?>' in the $config variable with '<?php echo selfUrl(); ?>' (with slash in the end) or other correct address to your server. Multiple CNAME can be used for better performance - more in <a href="readme.md">readme.txt</a>.

+Ready to go - just upload some maps into directory: <?php echo getcwd(); ?>/ on this server.
+</p>
+<p>
+Note: The maps can be a directory with tiles in XYZ format with metadata.json file.<br/>
+You can easily convert existing geodata (GeoTIFF, ECW, MrSID, etc) to this tile structure with <a href="http://www.maptiler.com">MapTiler Cluster</a> or open-source projects such as <a href="http://www.klokan.cz/projects/gdal2tiles/">GDAL2Tiles</a> or <a href="http://www.maptiler.org/">MapTiler</a> or simply upload any maps in MBTiles format made by <a href="http://www.tilemill.com/">TileMill</a>. Helpful is also the <a href="https://github.com/mapbox/mbutil">mbutil</a> tool. Serving directly from .mbtiles files is supported, but with decreased performance.
