Developer’s Corner: Using Default ImageMosaic CQL filter in GeoServer

Dear All,in this post we would like to describe how we did help our FAO colleagues with managing their huge ImageMosaics (containing multiple dimensions) by implementing an ImageMosaic improvement for GeoServer (2.2.x and 2.3.x) that allows to specify a default value for the Filter parameter it exposes.Before proceeding it is worth to provide some background information on how to create an ImageMosaic with additional dimensions (a-la WMS). Here below you can find some videos that shows how to do that.The ImageMosaic plugin gives you the possibility to configure a mosaic using an index that contains additional attributes which can be used to...

Behind the curtains: GeoServer/GeoTools ImageMosaic footprints management

Lately at GeoSolutions we have been working on improving the ImageMosaic capabilities as far as large mosaic with void areas are concerned. Often we need to mosaic several datasets which partially overlap which also contain areas where no data is defined (void areas); an example could be a set of satellite acquisitions with some missing areas (see pictures below).In the example above, the red borders represent the overlapping portions of the mosaic datasets; such portions partially overlap with other areas containing useful data for other datasets. A mosaic of these 2 datasets might produce a rendering like the one here...
