Re: [Geoserver-users] Configure Coverage with REST API

[Justin D. <jde...@op...>]

Hi Fernando,

So I tried this out, and basically here are the steps.

First you create the coverage store. POSTing some xml like this:

<coverageStore>
   <name>newCoverageStore</name>
   <enabled>true</enabled>
   <type>GeoTIFF</type>
   <url>file:coverages/some_dir/some_file.tiff</url>
</coverageStore>

Next you need to create the coverage. Now it appears that you have to 
specify much of the metadata, including:

srs
nativeCRS
nativeBoundingBox
latLonBoundingBox
dimensions

So POSTing something like:

<coverage>
  <name>newCoverage</name>
  <srs>EPSG:4326</srs>
  <nativeCRS>EPSG:4326</nativeCRS>
  <nativeBoundingBox>
    <minx>146.49999999999477</minx>
    <miny>-44.49999999999785</miny>
    <maxx>147.99999999999474</maxx>
    <maxy>-42.99999999999787</maxy>
    <crs>EPSG:4326</crs>
  </nativeBoundingBox>
  <latLonBoundingBox>
    <minx>146.49999999999477</minx>
    <miny>-44.49999999999785</miny>
    <maxx>147.99999999999474</maxx>
    <maxy>-42.99999999999787</maxy>
    <crs>EPSG:4326</crs>
  </latLonBoundingBox>
  <dimensions>
     <coverageDimension>
       <name>Red band</name>
       <description>GridSampleDimension[0.0,255.0]</description>
       <range>
         <min>0.0</min>
         <max>255.0</max>
       </range>
     </coverageDimension>
     <coverageDimension>
       <name>Green band</name>
       <description>GridSampleDimension[0.0,255.0]</description>
       <range>
         <min>0.0</min>
         <max>255.0</max>
       </range>
     </coverageDimension>
     <coverageDimension>
       <name>Blue band</name>
       <description>GridSampleDimension[0.0,255.0]</description>
       <range>
         <min>0.0</min>
         <max>255.0</max>
       </range>
     </coverageDimension>
   </dimensions>

</coverage>

This is pretty verbose. We should file a jira improvement to have the 
rest extension auto-configure properties when they are not specified. 
Like it goes when you upload via a zip file.

Hope that helps.
