geotiff tiff - Creating Store in GeoServer using ImageMosaic Plugin gives Error?


I am creating a GeoServer 2.4.1 store with GeoTiffs using the Image Mosaic Plugin and I get the following error when pressing the button


Could not list layers for this store, an error occurred retrieving them: 

Failed to create reader from file://C:\Geoserver Rasters\GeoTiffs\ and hints null

The Shape File describing the GeoTiffs IS Created in the directory.


I have tied with a single GeoTiff as well as multile files, same error.


I CAN create a store with the single tif file using the GEOTIFF Raster Data Store successfully but when using the ImageMosaic Plugin, it fails


Is there a problem with the file? How to I get these GeoTiff Files to display?


GDALINFO Reports the following on the single test file:

Answer



Try to put your geotiffs in a directory like this:


...\webapps\geoserver\data\data\myGeoTiffs

Much more, when creating you store, put this in the Connection Parameters URL:


file:data/myGeoTiffs



I've tried also to reproduce your error on my systems but I wasn't able to do it. (In my case everything works well even when I load the tiffs from anywhere outside the GeoServer data directory).


I think there could be another two possible causes:



1) Something wrong with your data:


Therefore, is it possible for you to upload on dropbox.com a zip with your data to be tested outside your computer? If it loads ok on mine computer then your ImageMosaic Plugin could be incompatible with your GeoServer version.


2) If the error appears again, then maybe the GeoTiffs wasn't properly produced:


In this case:


a) You could use gdal_translate, which could clean up the errors in the GeoTiffs headers.


b) Another approach would be to produce a vrt for your tiles. I've upload already such a mosaic here, for you, to test it.




Also, there is possible to see important hints about the error, when you try to create the store, if you check the GeoServer log.
