What can imagemosaic data store be used for?
The ImageMosaic data store allows the creation of a mosaic from a number of georeferenced rasters. The mosaic operation creates a mosaic from two or more source images. This operation could be used to assemble a set of overlapping geospatially rectified images into a contiguous image.
How is the Mosaic operation used in GeoServer?
The mosaic operation creates a mosaic from two or more source images. This operation could be used to assemble a set of overlapping geospatially rectified images into a contiguous image. It could also be used to create a montage of photographs such as a panorama.
What is the envelope for the imagemosaic plugin?
Envelope for the mosaic formatted as LLX,LLY URX,URY (notice the space between the lower left and upper right coordinate pairs). This parameter allows to specify whether the ImageMosaic plugin should check for the presence of a GDAL aux.xml file beside each granule file.
What is the root directory of a GeoServer?
When created by GeoServer it is by default called .properties, where is the name of the root directory of the store. (It is not related to the store name in GeoServer.) It can have other names, as long as it does not conflict with other files such as datastore.properties or indexer.properties.
Can you mix colored granules in imagemosaic?
The granules can be in different color models, with an allowance of mixing gray, RGB, RGBA and indexed color granules (it is however not possible to mix colored granules with scientific data types like as float/double). In order to benefit of mixed color models JAI-Ext support must be enabled, see the JAI-EXT support documentation.
When to set imagemosaic to true or false?
Boolean value to enable caching. When set to true, the ImageMosaic will try to save in memory the entire contents of the index to reduce loading/query time. Set to false for a large granule index and/or if new granules are to be ingested (for example, when the index is on a database and we interact directly with it).
