Re: [Geoserver-devel] Raster statistics

Hi Jody, I agree that we need a recalculation option. >From our side, we are interested on implementing the proposal for coverages but we don't have availability to do it on the short term (meaning that we might work on it on the last quarter of the year or the 1Q of 2017, but I can't warrant

Re: [Geoserver-devel] Raster statistics

This proposal came up in today's geosever meeting ( https://github.com/geoserver/geoserver/wiki/GSIP-140) - were you interested in perusing this topic? In addition to calculating during import (as proposed) we should allow "info" to be recalculated via the REST API. This same limitation is

Re: [Geoserver-devel] Raster statistics

Hi Simone, I have prepared a first draft for the proposal: https://github.com/geoserver/geoserver/wiki/GSIP-140 It is not too concrete regarding implementation, but I think it correctly outlines our requirement and how it would fit on the existing Geoserver infrastructure. Note that I have also

Re: [Geoserver-devel] Raster statistics

Ciao Cesar, the existing processes do not store aything. They can be used as a block-box/building block to compute what's needed and then use separate code to store it in the config. Regards, Simone Giannecchini == GeoServer Professional Services from the experts! Visit http://goo.gl/it488V for

Re: [Geoserver-devel] Raster statistics

Hi Simone, is the WPS process just calculating the stats, or is it also storing the results on the coverage? If it is doing both things, then it already covers our use case. If not, it would be worthy indeed to handle it as an asynch import, using the WPS process to get the results and storing

Re: [Geoserver-devel] Raster statistics

Dear Simone, I agree on creating a proposal to mature the exact scope and the best way to implement it on Geoserver. Some first ideas: - WHAT: 1) Read raster statistics (max & mean) if available on the raster data source 2) Compute min and max and store it on the CoverageDimension range (it

Re: [Geoserver-devel] Raster statistics

Dear Cesar, adding to Andrea's, your proposal is certainly interesting and we would be glad to devote some our time helping out with this. I would suggest to start with putting together a proposal that we can start discussing on. Regards, Simone Giannecchini == GeoServer Professional Services
