+# Cloud Optimized GeoTIFF File Sources
+
+Martin can serve local [COG(Cloud Optimized GeoTIFF)](https://cogeo.org/) files. For cog on remote like S3, you could track it on [issue 875](https://github.com/maplibre/martin/issues/875), we are working on and welcome any assistance.
+
+> A Cloud Optimized GeoTIFF (COG) is a regular GeoTIFF file, aimed at being hosted on a HTTP file server, with an internal organization that enables more efficient workflows on the cloud. It does this by leveraging the ability of clients issuing ​HTTP GET range requests to ask for just the parts of a file they need.
