[GIS] Doing OpenLayers.Request in OpenLayers 3

geoserveropenlayersrest

I have been searching for solutions to call GeoServer REST api from OpenLayers 3 for a long time.

I found that for OpenLayers 2, there is a OpenLayers class OpenLayers.Request for doing this:
http://docs.openlayers.org/library/request.html

But for OpenLayers 3, I can't find a similar class.
I tried a lot of online code for PHP proxying (andjsonp) trying to do the same without OpenLayers.Request, to no avail.

What is the correct/most reliable way to call GeoServer Rest from OpenLayers3 (or even general JavaScript with jQuery/AJAX)?

Internally OL3 uses Google Closure XhrIo to load data in vector layers.

OL3 philosophy has changed, now is a more concrete library, mainly oriented for gis mapping, instead a general purpose library like OL2.

OL3 leave to the user tasks like AJAX request. You can make them using XMLHttpRequest or through any other library like jQuery or Google Closure.

Geoserver Layer Bounding Box – How to Programmatically Set Bounding Box in PostGIS

This is already an old question, but I haven't found many example documenting this on he Web. On GeoServer version 2.5.1 the following should work (it should also work with older versions). :

Example XML

<layerGroup>

<workspace>workspace</workspace>
<name>014531_layer_group</name>
<layers>
<layer>014531_layer</layer>
<layer>014531_layer_watermark</layer>
</layers>
<styles>
<style>raster</style>
<style>sld_watermark</style>
</styles>
<bounds>
<minx>12.91</minx>
<miny>-6.97</miny>
<maxx>14.32</maxx>
<maxy>-5.44</maxy>
<crs>EPSG:4326</crs>
</bounds>
</layerGroup>

Example REST statement

sudo curl -v -u user:pwd -XPOST -d @yourxmlfile.xml -H "Content-type: text/xml" http://localhost:8080/geoserver/rest/layergroups

It doesn't take the bounding box of the underlying layer, but you could retrieve it by using a Selenium script

geoserver – Is Geoserver’s “Styler” Plugin Still Available?

The OpenGeo Suite's GeoExplorer now has the styling capability that Styler used to have. That must be why they shelved it.

You can get the code and installation instructions at Github.
