FOSS4G 2022 general tracks

Cloud-Native Geospatial with JavaScript
2022-08-24, 11:30–12:00 (Europe/Rome), Room Onice

The amount of Earth Observation data we have available nowadays is exceeding the capabilities for data processing. Therefore, a lot of data 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 data in so-called “cloud-native” file formats while data processing is also moving towards the data, i.e., into the cloud. This way you only need 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 best used with Browsers, which is the users’ main interface to the internet 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 client-side JavaScript:

This talk will dig into the available open-source libraries and, if JavaScript implementations are available, show their functionality based on examples. If multiple options are available, a high-level comparison will show the main differences in functionality. For COGs for example, we’ll compare the capabilities of the popular mapping libraries Leaflet, OpenLayers and MapLibre GL.

Daniel Dufour is the CEO of GeoSurge, a geospatial tech company with a focus on data compression, natural language processing, remote sensing, and visualization. He created or co-created several open-source geospatial projects, including, georaster, georaster-layer-for-leaflet, geoblaze, geowarp, and proj4-fully-loaded.
