DESCRIPTION:The amount of Earth Observation data we have available nowadays
  is exceeding the capabilities for data processing. Therefore\, a lot of d
 ata is now made available in the cloud. To make digesting the data easier 
 and more-lightweight\, it is getting more and more popular to store the da
 ta in so-called “cloud-native” file formats while data processing is a
 lso moving towards the data\, i.e.\, into the cloud. This way you only nee
 d to retrieve the actual subset of the data you are actually interested in
  instead of the full data set\, which can be in the magnitude of gigabytes
  or even larger. This technology of cloud-native file formats is usually b
 est used with Browsers\, which is the users’ main interface to the inter
 net and the cloud. There the main language is JavaScript. Therefore\, this
  talk will give a high-level introduction about the relevant cloud-native 
 file formats and show whether and how you can make use of these files in c
 lient-side JavaScript:\n\n- COG: Cloud-Optimized GeoTiff ( https://www.cog
 eo.org )\n- COPC: Cloud-Optimized Point Clouds ( https://copc.io )\n- Flat
 geobuff ( https://flatgeobuf.org )\n- GeoParquet ( https://github.com/open
 geospatial/geoparquet )\n- STAC: SpatioTemporal Asset Catalog ( https://st
 acspec.org )\n- Zarr ( https://zarr.readthedocs.io )\n\nThis talk will dig
  into the available open-source libraries and\, if JavaScript implementati
 ons are available\, show their functionality based on examples. If multipl
 e options are available\, a high-level comparison will show the main diffe
 rences in functionality. For COGs for example\, we’ll compare the capabi
 lities of the popular mapping libraries Leaflet\, OpenLayers and MapLibre 
 GL.
