Managing GridSets through the REST API¶

The REST API for GridSet management provides a RESTful interface through which clients can programatically add, modify, or remove GridSets.

GridSets list¶

/rest/gridsets.xml

Method	Action	Return Code	Formats
GET	Return the list of available gridsets	200	XML, JSON
POST		405
PUT		405
DELETE		400

Sample request:

curl -u geowebcache:secured  "http://localhost:8080/geowebcache/rest/gridsets"

Sample response:

<gridSets>
  <gridSet>
    <name>EPSG:2163</name>
    <atom:link xmlns:atom="http://www.w3.org/2005/Atom" rel="alternate" href="http://localhost:8080/geowebcache/rest/gridsets/EPSG:2163.xml" type="text/xml"/>
  </gridSet>
  <gridSet>
    <name>GlobalCRS84Pixel</name>
    <atom:link xmlns:atom="http://www.w3.org/2005/Atom" rel="alternate" href="http://localhost:8080/geowebcache/rest/gridsets/GlobalCRS84Pixel.xml" type="text/xml"/>
  </gridSet>
  <gridSet>

  </gridSet>
  <gridSet>
    <name>GlobalCRS84Scale</name>
    <atom:link xmlns:atom="http://www.w3.org/2005/Atom" rel="alternate" href="http://localhost:8080/geowebcache/rest/gridsets/GlobalCRS84Scale.xml" type="text/xml"/>
  </gridSet>
</gridSets>

GridSet Operations¶

/rest/gridsets/gridset.xml

Method	Action	Return Code	Formats
GET	Return the XML representation of the GridSet	200	XML, JSON
POST		405
PUT	Add a new GridSet or modify the definition of a GridSet.	200	XML, JSON
DELETE	Delete a GridSet	200

Representations:

XML
JSON

REST API for GridSets, cURL Examples¶

The examples in this section use the cURL utility, which is a handy command line tool for executing HTTP requests and transferring files. Though cURL is used the examples apply to any HTTP-capable tool or library.

Add GridSet¶

Given a gridset.xml file as the following:

<gridSet>
  <name>EPSG:2163</name>
  <srs>
    <number>2163</number>
  </srs>
  <extent>
    <coords>
      <double>-2495667.977678598</double>
      <double>-2223677.196231552</double>
      <double>3291070.6104286816</double>
      <double>959189.3312465074</double>
    </coords>
  </extent>
  <alignTopLeft>false</alignTopLeft>
  <scaleDenominators>
    <double>2.5E7</double>
    <double>1000000.0</double>
    <double>100000.0</double>
    <double>25000.0</double>
  </scaleDenominators>
  <metersPerUnit>1.0</metersPerUnit>
  <pixelSize>2.8E-4</pixelSize>
  <scaleNames>
    <string>EPSG:2163:0</string>
    <string>EPSG:2163:1</string>
    <string>EPSG:2163:2</string>
    <string>EPSG:2163:3</string>
  </scaleNames>
  <tileHeight>200</tileHeight>
  <tileWidth>200</tileWidth>
  <yCoordinateFirst>false</yCoordinateFirst>
</gridSet>

curl -v -u geowebcache:secured -XPUT -H "Content-type: application/xml" -d @gridset.xml  "http://localhost:8080/geowebcache/rest/gridsets/gridSet1.xml"

Or if using the GeoServer integrated version of GeoWebCache:

curl -v -u user:password -XPUT -H "Content-type: application/xml" -d @gridset.xml  "http://localhost:8080/geoserver/gwc/rest/gridsets/gridSet1.xml"

Modify GridSet¶

Now, make some modifications to the gridset definition on the gridset.xml file:

<gridSet>
  <name>EPSG:2163</name>
  <srs>
    <number>2163</number>
  </srs>
  <extent>
    <coords>
      <double>-2495667.977678598</double>
      <double>-2223677.196231552</double>
      <double>3291070.6104286816</double>
      <double>959189.3312465074</double>
    </coords>
  </extent>
  <alignTopLeft>false</alignTopLeft>
  <scaleDenominators>
    <double>2.5E7</double>
    <double>1000000.0</double>
    <double>100000.0</double>
    <double>25000.0</double>
    <double>5000.0</double>
    <double>1000.0</double>
  </scaleDenominators>
  <metersPerUnit>1.0</metersPerUnit>
  <pixelSize>2.8E-4</pixelSize>
  <scaleNames>
    <string>EPSG:2163:0</string>
    <string>EPSG:2163:1</string>
    <string>EPSG:2163:2</string>
    <string>EPSG:2163:3</string>
    <string>EPSG:2163:4</string>
    <string>EPSG:2163:5</string>
  </scaleNames>
  <tileHeight>256</tileHeight>
  <tileWidth>256</tileWidth>
  <yCoordinateFirst>false</yCoordinateFirst>
</gridSet>

curl -v -u geowebcache:secured -XPUT -H "Content-type: application/xml" -d @gridset.xml  "http://localhost:8080/geowebcache/rest/gridsets/gridSet1.xml"

Delete GridSet¶

Finally, to delete a gridset, use the HTTP DELETE method against the gridset configuration:

curl -v -u geowebcache:secured -XDELETE "http://localhost:8080/geoserver/gwc/rest/gridsets/gridSet1.xml"
