GDAL provides extensive capabilities for processing GeoTIFFs and other spatial data formats. However, until recently, the use of GDAL in web applications was limited to server-side code. This talk will describe how we use WebAssembly and a new wrapper library we developed, called Loam, to make GDAL's suite of tools accessible from client-side code. This strategy enables improved user experiences and can lower infrastructure costs for web applications handling GeoTIFFs and other spatial data.
