A demo titiler for Sentinel 2 Digital Twin dataset

Last update: May 21, 2022

Overview

titiler-digitaltwin

This is a DEMO custom api built on top of TiTiler to create Web Map Tiles from the Digital Twin Sentinel-2 COG created by Sinergise. For more information about the dataset please checkout: https://medium.com/sentinel-hub/digital-twin-sandbox-sentinel-2-collection-available-to-everyone-20f3b5de846e

white tiles!

there is a bug when you zoom/pan, some tile might appear white and then full of data. This is because of the multi task https://github.com/cogeotiff/rio-tiler/blob/master/rio_tiler/tasks.py#L14-L38

usually we only filter out TileOutsideBounds. For the DigitalTwin we don't know in advance if a file exist for a specific mercator tile. when a request is made for a specific data, we first get the intersecting MGRS grid https://github.com/developmentseed/titiler-digitaltwin/blob/d1fe7c6178b2700a9c72d023a949fabb809a5fb8/src/titiler_digitaltwin/reader.py#L175-L178

and then the S2DigitalTwinReader construct the file name of the dataset. https://github.com/developmentseed/titiler-digitaltwin/blob/d1fe7c6178b2700a9c72d023a949fabb809a5fb8/src/titiler_digitaltwin/reader.py#L87-L90

I've added RasterioIOError to the allowed exceptions in https://github.com/developmentseed/titiler-digitaltwin/blob/main/src/titiler_digitaltwin/mosaic.py#L154 but It doesn't seems to do the trick 🤷‍♂️
