Though the computations are not as accurate as\nthe high-res tables they support, they can be sufficient in many\nrule-of-thumb computations.\n\nhttp://postgis.net/docs/manual-2.4/using_raster_dataman.html#RT_Raster_Overviews\n\nMore info at:\nhttps://github.com/CartoDB/cartodb/wiki/Automatic-raster-overviews","distinct":true,"url":"https://api.github.com/repos/akvo/akvo-lumen/commits/79780185314fd5679557fad2b7edbe568903279b"}]}
