integrating qgis into expressJs based web application for tiff images #28

Closed Rjaat closed 7 months ago

Rjaat commented 9 months ago

I am working on an expressJS based web application which is primarily intended to object detection from tiff images. As of now, i am using openseadragon for loading the tiff images inside the application but it takes too much time. So i had a thought of using QGIS interface inside my application for loading the tiff images. can anyone help with this?

Hi @Rjaat As for now, qgis-js faces an architectural issue which prevents loading a project with remote/COG tiff images (tracked in https://github.com/qgis/qgis-js/issues/4). This means that for the moment you would have to fetch the entire image and upload it to the qgis-js runtime in order to render it. This works fine, for example in the village project, but is probably not feasible for a large tiff image. Note that if you can export it as a COG, you could also use OpenLayers directly (see https://openlayers.org/en/latest/examples/cog.html)
