DESCRIPTION:This is a technical feedback about why the COG (Cloud Optimized
  GeoTIFF) format is valuable outside the cloud and can speed up productivi
 ty in many ways.\n\nDuring first months\, remote work and COVID\, IT depar
 tment was overbooked and has to face to many issue such bandwidth limitati
 on. Images display was suffer in GIS client. Of course\, webservice was al
 ways available but user has to control on band order or radiometry setting
 s. WCS is supposed to be the solution. Unfortunately\, it offered degraded
  performance.\n\nCOG is supposed to be serve from HTTP server or S3. But w
 e’ve simply test from a network drive / mount point and it offer great p
 erformance. Depending internet connection\, it could be as fast as it is i
 n local ! \nCOG advantage must be consider outside of the cloud as remote 
 work tends to develop more and more. It could avoid to deploy heavy webser
 vice infrastructure for only raster visualization. \n\nFrom other side\, b
 enchmark between publish some other format compare to COG in GeoServer. Fr
 om Regional Data Infrastructure\, it’s streamline storage data between r
 aster format as input file for webservices and opendata raw downloading se
 rvices as open archives.\n\nFinally\, I will give some feedback and tips a
 nd tricks to find best parameters to convert orthophotography\, DEM or DSM
 \, etc. to COG.
