Publishing big geotiff files

van Ingen, Erik

Dear Geoserver community,

 

This page

https://geoserver.geo-solutions.it/edu/en/enterprise/raster.html#

suggests to use GDAL for preparing big GeoTiff files.

 

A couple of related questions:

·         Does "consider BigTiff for large files (> 4 GB)"  imply Geotiff for < 4GB?

·         Is GDAL the best tool to use for preparing large GeoTiff files for publication in Geoserver? Are there alternatives?

·         Ideally we only push only the GeoTiff files with an SLD to Geoserver and do nothing more. Is there a way to automate as much as possible the publication of large GeoTiff files? What is the best practice to publish GeoTiff files up to 10GB? and to up to 20GB?

 

Kind Regards,

Erik

Yes

Yes and Yes, however we do suggest GDAL even because most of the other tools use GDAL behind the scenes, anyway.

 

·         Ideally we only push only the GeoTiff files with an SLD to Geoserver and do nothing more. Is there a way to automate as much as possible the publication of large GeoTiff files? What is the best practice to publish GeoTiff files up to 10GB? and to up to 20GB?


If they are independent layers you can use the REST API, if they somehow part of a time series I would set up an ImageMosaic with an index in Postgis and then use the harvesting API of the imagemosaic-- > https://geoserver.geo-solutions.it/edu/en/multidim/rest/index.html

There is also a nice importer extension which has its own REST API and which can also automated tasks like calling gdal_translate and gdal_addo on the command line as part of an ingestion --> https://docs.geoserver.org/stable/en/user/extensions/importer/rest_examples.html.
