I have two Geotiff files. with one side overlapping. Each Geotiff is surrounded by a black frame.
I have created an Image Pyramid with Geoserver 2.3.0 but when I try to see the layer on OpenLayers, the layer borders appear in black, so I can't see correctly the layer, because of thats black borders.It looks like tiles in the pyramid already has black zones inherited from the original tiffs.
I've followed these steps:
First I have execute the next command on tiles to convert to Image Pyramid:
gdal_translate -a_nodata 0 <origin.tif> <target.tif>
When I have executede this command, I executed the next one:
gdal_retile.py -levels 3 -ps 2048 2048 -co "TILED=YES" -co "BLOCKXSIZE=256" -co "TILED=YES" -co "BLOCKXSIZE=256" -co "BLOCKYSIZE=256" -targetDir tiles --optfile tiles.txt -s_srs EPSG:32719 -targetDir tiles --optfile tiles.txt
After that I try to make the Image Pyramid with Geoserver, but the result is the same that at first, I preview the layer on Openlayers and it appears with black borders.
I think Image Pyramid plugin is properly configured:
- InputTransparentColor: #000000
- OutputTransparentColor: #000000
- SUGGESTED_TILE_SIZE: 512,512
- USE_JAI_IMAGEREAD: true
I don't know what I must to do.
Any help, please???
