In case there is a dataset ending with @2x and another dataset without - the @2x should be hidden and in the TileJSON should be mentioned: autoscale:true
Example:
http://api.tiles.mapbox.com/v3/examples.map-20v6611k.jsonp
Such datasets serve two tile requests:

https://d.tiles.mapbox.com/v3/examples.map-20v6611k/6/33/22.png
and

https://d.tiles.mapbox.com/v3/examples.map-20v6611k/6/33/[email protected]

Unfortunately - this is pretty bad way for implementing retina tiles - as made by MapBox.
Normally Google Maps and other libraries loads a 512x512 px png tile instead of the 256x256px for the same location - on the same tile index. This MapBox implementation is one level off - and still uses 256px tiles.

TileServer PHP now fully supports TileJSON, but it is not advertised in the user interface.

It is expected that TileServer PHP passes to the JavaScript constructor of user interface a variable 'tilejson' with a format similar to http://servername/path/%n.json, later the JavaScript will replace %n with the name of the selected layer.

It was reported that new version of qgis (2.6) can't open wmts from tileserver-php. We need to test it.

not really an issue, but an enchancement: to support UTFgrid, at least with mbtiles ?

Request to tileserver.php could return correct HTML and send a request to itself without a need for .htaccess in the directory.

I expect that tileserver.php?/index.json returns what would be normally mapped to index.json.

http://tileserver.maptiler.com/tileserver/tileserver.php?/index.json

We need to improve the look&feel of the project and provide a simple OpenLayers based viewer at the address /layer-name/.

The basis are ready in the 'design' branch already.

TileServer should check validity of detected url. It should happen only before displaying the main html. TileServer has problem with few servers configuration if it's run on subdirectory. E.g. http://labs.klokantech.com/tileserver/

Related to the new release of tileserver-js

Implement serving from a GeoPackage storage (SQLite based) as a more general alternative to MBTiles allowing also support for non-speherical mercator coordinate systems.

I'm having trouble showing a tiled map from an mbtiles-file. Some images, especially at higher zoomlevels, don't get displayed sometimes. The behaviour seems random; the same image sometimes is displayed, and sometimes not.

If you reload an image several times, you will see that it sometimes shows up correctly, but sometimes nothing is shown.

http://myserver.com/tiles/tileserver.php?/pc4_multi/17/67546/43194.png

(I've removed the real url to the server; please contact me if you'd like to test.)

A little debugging shows that when it isn't displayed, no data is returned from the query on the mbtiles database: $data == FALSE in line 311.

Any idea what causes this problem or how to diagnose it further?

The grandcanyon demo is not loading correctly - we should probably contact the author of ArcBruTiles and ask how to implement the TMS XML metadata.

Or is there somewhere a demo which does not not cover whole earth and it is loading ArcBruTiles well?

This should be implemented:

  <TileMatrixSetLink>
    <TileMatrixSet>EPSG:4326</TileMatrixSet>
    <TileMatrixSetLimits>
      <TileMatrixLimits>
        <TileMatrix>EPSG:4326:0</TileMatrix>
        <MinTileRow>1</MinTileRow>
        <MaxTileRow>1</MaxTileRow>
        <MinTileCol>0</MinTileCol>
        <MaxTileCol>0</MaxTileCol>
      </TileMatrixLimits>
      <TileMatrixLimits>
        <TileMatrix>EPSG:4326:1</TileMatrix>
        <MinTileRow>1</MinTileRow>
        <MaxTileRow>1</MaxTileRow>
        <MinTileCol>0</MinTileCol>
        <MaxTileCol>0</MaxTileCol>
      </TileMatrixLimits>

...

All the required math is in globalmaptiles.py at http://www.maptiler.org/google-maps-coordinates-tile-bounds-projection/ we just need to port it to PHP.
This has been partly done already: http://bafford.com/software/aggregate-map-tools/GlobalMapTiles.php.txt

Hi, nice and awesome tool from you.. :)

I have a question.
Is it only supports MBTiles with TMS specification? --- The inverted Y one?

When I'm trying to use MBTiles with ZXY-OSM specification
(with normal Y from north to south), the map got upside down on each tile.

It seems TileServer.php automaticaly revert the Y order to the output:

• When the source is ZXY-TMS MBTiles (the reverted Y), the output on the map is correct.
• When the source is ZXY-OSM MBTiles (the normal Y), the output got upside down.

From my dummy-test MBTiles files, it would be seen like that.
The ZXY-TMS is got right, the ZXY-OSM got wrong. Both on z/x/y.jpg output and WMTS output.

It would be great if it supports both format, ZXY-TMS and ZXY-OSM in the future.

Because MBTiles will drop TMS format (inverted Y order, from south to north) in the future,
and start developing ZXY-OSM format (normal Y order from north to south).

As you can see here:
https://github.com/mapbox/mbtiles-spec#roadmap

"The MBTiles format will switch tile ordering to the XYZ schema popularized by OpenStreetMap and away from the Tile Map Service (TMS) specification."

Dear all,

it seems the tiljson generation of tileserver-php has an issue with URLs. Tileserver escapes URL slashes (as per json_encode semantics), whereas the tilejson specs appear to require an unquoted string.

Here is an example of wax and leaflet failing to load a tileserver-php provided tilson map.

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>A simple map</title>
<meta name='viewport' content='initial-scale=1,maximum-scale=1,user-scalable=no' />

<style>
  body { margin:0; padding:0; }
  #map { position:absolute; top:0; bottom:0; width:100%; }

</head>

<div id='map'></div>
<script>
var map = L.mapbox.map('map', 'http://tileserver.maptiler.com/grandcanyon.json')
    .setView([40, -74.50], 3);
</script>

</body>
</html>

The problem is

"tiles":["http:\/\/tileserver.maptiler.com\/grandcanyon\/{z}\/{x}\/{y}.png"]

Wihle the specs (https://github.com/mapbox/tilejson-spec/tree/master/2.1.0) require

"tiles": [
        "http://localhost:8888/admin/1.0.0/world-light,broadband/{z}/{x}/{y}.png"
    ],

The problem seems to be the json_encode in lines 519 and 529 of tilesever.php .

I do not know if this is a tileserver-php or leaflet and wax issue?

Layers ending with @2x should return 512x512px empty tile instead of 256x256px.
It is about change of getCleanTile - probably passing width while knowing about retina.

http://tileserver.maptiler.com/grandcanyon@2x/12/769/1608.png
http://ol3js.org/en/master/examples/xyz-retina.html

The report is form @fredj:

Some retina tiles (those with a @2x in the name) do not have a correct size (256 instead of 512).
Example: http://tileserver.maptiler.com/grandcanyon@2x/12/769/1608.png

The wrong tiles appears to be only the "empty" one (transparent png)

The issue is visible with the ol3 example: http://ol3js.org/en/master/examples/xyz-retina.html but only with firefox (IndexSizeError in the console).

I copied my .mbtiles file to the tileserver directory. When I go to view them, I can only see the base map, not the map I created in Tile Mill.

#0 /var/www/XXX.com/maps/tileserver.php(254): PDO->__construct('sqlite:geograph...', '', '', Array)

Does anyone know what I'm doing wrong? Thanks.

It would be great to start to use index.php for the HTML interface.

This interface should also check the proper installation - including the test of URLs (already done in the tileserver.php) and of the availability of .htaccess file.

Ideas for proper .htacess tests:

• check file by is_readable(".htaccess")
• print_r(apache_get_modules()) will show you the loaded Apache modules (only if PHP runs as a module as well)
• use "SetEnv TILESERVER ok" in .htaccess and "$indexUrl = getenv('TILESERVER');" in PHP.

It seems there is a depency on the GD module of PHP just to serve an empty tile. Probably a string constant with a few bytes for 1x1PNG and JPEG would be faster and easier to make - in case functions like imagecreatetruecolor are not available on the server.

Tileserver works very well as a WMTS layer in QGIS but if I try to print the layer I am given a warning shown below and this does appear to be the case or at least the map tiles do not appear on the print out (are shown in composer)

Does Tileserver have a limit as per the warning below or is something else preventing printing of the tiles in QGIS?

Some WMS servers (e.g. UMN mapserver) have a limit for the WIDTH and HEIGHT parameter. Printing layers from such servers may exceed this limit. If this is the case, the WMS layer will not be printed

The index.json for empty directory has only ]. To be [].

hi!
congrats for this code, works fine on a normal vps but in a shared host from 1and1
i receive this message when I try to load an utfgrid
(i've used the recomended lines on the htaccess)

for example:

for this url, used on ol3 as a utfgrid source
http://atnight.ws/bcndynamics/tileserver/d0100.json
i receive this console error

Uncaught SyntaxError: Unexpected token <
d0100.json?callback=callbacks._12if3txcg7:1

• also the tileserver home page shows me this url for my tiles
  http://atnight.ws/bcndynamics/tileserver/?%2Findex.json&callback=_callbacks_._0if3tymsk?/d0100/{z}/{x}/{y}.png

** an example of a working tiles is this
http://atnight.ws/bcndynamics/tileserver/d0100/14/8288/6120.png
http://atnight.ws/bcndynamics/tileserver/d0100/14/8288/6120.grid.json

i'm not able to understand what's happening...
someone knows something about this error?

Hi - I'm using tileserver with an uncustomized mapbox example and getting the error:

Uncaught SyntaxError: Unexpected token _
<img width="1637" alt="screen shot 2015-10-28 at 3 40 21 pm" src="https://cloud.githubusercontent.com/assets/520541/10800822/6648c6dc-7d8a-11e5-9dae-b346bb651d18.png">

Basically all I've done is download tileserver, serve it on a local MAMP server, drop an .mbtile file exported from tilemill into the tileserver directory, and load up tileserver.php, and click on the "preview" link under mapbox.

The request out of the bounds of vector tiles or not found pbf blobs should respond with a proper empty pbf tile probably... related to existing implementation of vector tiles #42.

I'm using a 14GB mbtile file with tileserver and it seems it takes a lot of time to load the initial server page. With smaller files (around 1-2 GB) things are almost instant.

Currently the thumb image seems to be taken "randomly" in the middle of the world and middle zoom… Isn't there a better way with which we could decide where it is? At least make it an existing tile?

Tileserver could be faster when it could be possible to create cache files of metadata. Idea:

1. create variable in globalconfig 'cache' with values true or false (default could be false)
2. if global cache is true, tileserver will generate cache files if they are requested:
   a) index.json
   b) layer1json, layer2.json etc.
   c) we can also cache wmts files to file like wmts/1.0.0/WMTSCapabilities.xml
3. Create link for quick working with cache:
   www.server.dom/cache-clean - delete cache
   www.server.dom/cache-create - create cache

With this we can compute more metadata attributes in future.

We can store cache into root directory when tileserver.php is located and serve it via webserver or store it in folder 'cache' and serve it via script (first check if file exists, then return file or create and return).

http://www.maptiler.com/

And include the banner:

Provide visualizations and WMTS in local coordinate systems from GeoPackage implemented in #46

Create one single php file which will check if hosting is ready for installing tileserver. This script will do:

• validate baseurl and display it
• check mod rewrite
• check support for sqlite

if (!extension_loaded('pdo_sqlite')) {
    # HTTP Error 500
    echo "PHP: PDO SQLite extension is not installed";
    die;
}

• check version of php

It would be great to integrate a functionality for:

• create and edit basic vector data on top of a tileset (add and edit markers, geonames for place search, transcriptions, or basic vectorization - markers, polygon, lines + attributes). Something like an integrated http://geojson.io/ or it's rewrite in OL3)
• allow import of vector data (drag & drop of GeoJSON/SHP/KML ...) a la geojson.io
• allow export / download (client side generators) a la geojson.io
• link existing online vector data (url to a geojson) to a tileset. Multiple vector data may be linked.

It seems to me the best storage for small vector data like these is a GeoJSON format saved on GIST or a GitHub repo. Alternative would be a local storage in PHP, but it has disadvantages in interoperability and advantages in independence.

Hi,

I've installed tileserver-php and everything seems to be fine except a problem with the tileserver.js file.

In firebug I've got this error:
TypeError: a[f].tiles is undefined
.../Math.cos(k[1]_Math.PI/180))/Math.PI)/2_Math.pow(2,k[2]))),h=h.replace(/{z}/gi,k...

When I keep the tileserver.js file, I've got the blue header but nothing after just a white page. When I delete the call to this script in tileserver-php.php I can see the list of my maps.

Do you know what I should do to have the interface with all the maps like it is in the description of tileserver-php ?

Thanks

Arnaud

Is it possible to allow TileServer to use a custom template by default? Idea: Set path to template in config variable e.g. $config['template'] = 'leaflet.php';
If it's not set TileServer will use default viewer.

In template will be added PHP variables for custom use:
$baseUrls (array) - url to tileserver from config variable
$serverTitle (string) - Title from config variable
$maps (array) - with metadata about layers

First of all, let me say that the tileserver works (and it works amazingly fast):
I can import my pre-rendered tiles (mbtiles and folders) both in QGIS and with Leaflet, and everything looks great.

However all the times I try and load the tileserver.php, the server "homepage" with my tiles, I receive the following warnings and the page is empty:

1. Chrome:
   Uncaught TypeError: Cannot read property '0' of undefined (tileserver.js:123)
2. Firefox:
   TypeError: k is undefined (tileserver.js:123)

http://liber.isma.cnr.it/tileserver-php/

It appears to me that such a problem may be explained by my server errorlog which says:
PHP Warning: file_get_contents(tileserver/metadata.json): failed to open stream: No such file or directory in /var/www/html/SERVER/www/tileserver.php on line 151, referer: http://SERVER/
and as a result:
PHP Warning: array_key_exists() expects parameter 2 to be array, null given in /var/www/html/SERVER/www/tileserver.php on line 173, referer: http://SERVER/
PHP Warning: array_key_exists() expects parameter 2 to be array, null given in /var/www/html/SERVER/www/tileserver.php on line 177, referer: http://SERVER/

I cannot figure it out if this problem depends on my server misconfiguration (mod_write is enabled) or form something else.

All the best, and thank you for this awesome software

Is there any way to prevent users from downloading your .mbtiles file with this implementation? Normally, I would just add this to my .htaccess file:

<FilesMatch "\.(htaccess|mbtiles)$">
 Order Allow,Deny
 Deny from all
</FilesMatch>

But this is too restrictive as it blocks the streaming of tiles as well.

Thanks!

It is possible to find an installation guide of tileserver-php in OSGeo4W?. Currently does not recognize files MBTILES.

The error log apache:

Thanks for your great software and for the reply.

Tests for PHP - running automatically by Travis-CI on GitHub.

tilserver-php fails with > PHP 5.4 due to three functions not having the expected signatures.

The following patch seems to fix it.

568c568
<   public function getUTFGrid() {

---
>   public function getUTFGrid($tileset, $z, $y, $x, $flip = true) {
1085c1085,1086

>   {
1214c1215
<   public function getTile() {

---
>   public function getTile($tileset, $z, $y, $x, $ext) {

The mbtiles are generated with TileMill from shapefiles, on the same region, with some predefined colors. Each time the online interface is refreshed, the maps are rendered in differents colors, like you can see on the two first screenshots.
With leaflet (or OL, ...), some tiles are rendered in a color and all with another, depending on the zoom factor (last screenshot).
This problem doesn't seem to happen with the tileserver.php from infostreams.

I use the last tileserver.php from github, with Nginx on Ubuntu 14.04.

The Conditional get (HTTP 302) - ETag as MD5 based on the modification time of the .mbtiles file.

Turn on by default.

By looking at recent changes of tileserver.php source code, .grid.json files are returned by the statement echo 'grid(' . $grid . ');';. This creates a grid(file.json) which apparently is not conform to the json file that one would expect (for instance, OpenLayers.Control.UTFGrid does not work with such a format).
Switching back to the earlier solution, echo $grid;, instead do the trick.

This is a working example with the proposed patch:

Hello,

I have noticed that ArcGIS online has a problem selecting the right layer when multiple mbtiles layers are made available by tileserver-php.

The map editor in ArcGIS allows to add an OGC WMTS layer. After inputting the URL to a WMTS service, it issues a getCapabilities an lets the user select from all available layers.
The issue is that ArcGIS seems to always load the first layer, no matter which one was actually selected. This is if I have "1-map, 2-map, 3-map" tile layers available, what is shown in the ArcGIS map is always "1-map", even though I selected 2-map or 3-map.

I have verified that what is requested by ArcGIS is actually the first layer, thus excluding that the mapserver somehow delivers the wrong content. (by checking webserver logs)
I have also verified that ArgGIS can in general correctly handle selecting one of multiple available layers (by pointing it to v2.suite.opengeo.org/geoserver/gwc/service/wmts/, where the selected layer is shown, no matter which one was selected).

I thus believe that ArcGIS somehow incorrectly parses the getCapabilities request of tileserver-php, or that some element ArgGIS requires is missing in the request.
Comparing a working and a non-working example of getCapabilities requests, I noticed differences in the "TileMatrixSetLimits" elements.

I do not know enough about the WMTS getCapabilities spec to tell what could trigger this behaviour.

Any clues why ArcGIS always requests the first layer from a tileserver-php server?

thanks a lot
kurt

Serving MBTiles with vector tiles generated by MapBox Studio, aka serve .pbf requests.

Initial notes are in:
http://gis.stackexchange.com/questions/125037/self-hosting-mapbox-vector-tiles

Hi,

I'm trying to get a map from an .mbtiles file generated by Tilemill, but when I load it to my localhost directory (where of course there are all your files) and open the browser I don't get anything at all .
So I tried using mbutils to create a directory with all the tiles and metadata.json, but again, putting all your files in that directory and opening the brower just gets me a blank page (though this time i do get your tileserver header and firebug detects an "invalid json string error").

Could you tell me what am I possibly missing? Thanks!

Response error when there are no data.

The code does not yet contain the MBTiles implementation. We can port this project: https://github.com/Zverik/mbtiles-php.

Keep in mind the Conditional get (HTTP 302) - based on the modification time of the .mbtiles file.
http://simonwillison.net/2003/apr/23/conditionalget/

This file rendered with tilemill breaks the tileserver-php:
https://0aa236b767d39325c1f8c7a73e82b09ee058db69.googledrive.com/host/0BwUe1kqIRJWSV0J6R3RGNV8zcXc/

tileserver does not recognize if stuff is requested from it via http or https when generating the service metadata. This can be a problem with new browsers that do not like http content being pulled in when the original connection was https. (above all a problem when tileserver and map-using site run on the same domain).
This is, when I request https://mydomain/mymap.json, the service metadata has "grids":["http://mydomain/mymap/{z}/{x}/{y}.grid.json"] , causing the browser to request http stuff whereas the original request was https.. newer versions of chrome and FF do not like that and fail.

A patch against an earlier version of tileserver.php is attached
