In #28 and #80, we've developed a geographic sampling scheme based on WorldCover that is supposed to sample a diverse set of regions based on landcover types. However, in #60/#68,...
_Originally posted by @ritwikvashistha in https://github.com/Clay-foundation/model/issues/161#issuecomment-2002602847_ > Hi, I tried using the model on my Mac M1 Pro as well as on Binder. But I ran into the same issue...
Idea that came up during our regular meetings, on generalizing the cloud-cover percentage patch-level info (i.e. extending #168) to other bands/channels, so that someone could apply other filters based on...
Draft tutorial for Digital Earth Pacific. Using the STAC API at https://stac.staging.digitalearthpacific.org and looking at their Sentinel-2 GeoMAD and Sentinel-1 mean composite. Note that I've used [`jupytext`](https://github.com/mwouts/jupytext) to pair the...
Jupyter notebook script to generate GeoParquet embedding files on a per MGRS tile basis. Steps: 1. The script first generates an mgrs_world.txt file with a list of MGRS code names...
Training foundation models can use up a lot of energy and emit signficant amounts of carbon emissions, and we should be transparent on this, since the Clay Foundation Model has...
Using mean and standard deviation normalization is a common procedure in standard Computer Vision, and can be applied e.g. by using `torchvision`'s [Normalize](https://pytorch.org/vision/main/generated/torchvision.transforms.Normalize.html) function. But this normalization can lead to...
A mmsegmentation configuration file for the irrigation_scenes dataset on https://huggingface.co/datasets/ibm-nasa-geospatial/hls_irrigation_scenes. As this is a time-series dataset with data from four months stored in four different folders, a custom SpatioTemporalDataset class...
Just got some great ideas after attending this Cloud-Native Geospatial Event (https://schedule.cloudnativegeo.org) and learned a lot about Spatial Temporal Asset Catalogs (STAC) and OGC API standards! So the people working...
