TorchGeo 0.6.0 Release Notes

TorchGeo 0.6 adds 18 new datasets, 15 new datamodules, and 27 new pre-trained models, encompassing 11 months of hard work by 23 contributors from around the world.

Highlights of this release

Multimodal foundation models

There are thousands of Earth observation satellites orbiting the Earth at any given time. Historically, in order to use one of these satellites in a deep learning pipeline, you would first need to collect millions of manually-labeled images from this sensor in order to train a model. Self-supervised learning enabled label-free pre-training, but still required millions of diverse sensor-specific images, making it difficult to use newly launched or expensive commercial satellites.

TorchGeo 0.6 adds multiple new multimodal foundation models capable of being used with imagery from any satellite/sensor, even ones the model was not explicitly trained on. While GASSL and Scale-MAE only support RGB images, DOFA supports RGB, SAR, MSI, and HSI with any number of spectral bands. It uses a novel wavelength-based encoder to map the spectral wavelength of each band to a known range of wavelengths seen during training.

The following table describes the dynamic spatial (resolution), temporal (time span), and/or spectral (wavelength) support, either via their training data (implicit) or via their model architecture (explicit), offered by each of these models:

Model	Spatial	Temporal	Spectral
DOFA	implicit	-	explicit
GASSL	implicit	-	-
Scale-MAE	explicit	-	-

TorchGeo 0.6 also adds multiple new unimodal foundation models, including DeCUR and SatlasPretrain.

Source Cooperative migration

TorchGeo contains a number of datasets from the recently defunct Radiant MLHub:

These datasets were recently migrated to Source Cooperative (and AWS in the case of SpaceNet), but with a completely different file format and directory structure. It took a lot of effort, but we have finally ported all of these datasets to the new download location and file hierarchy. As an added bonus, the new data loader code is significantly simpler, allowing us to remove 2.5K lines of code in the process!

OSGeo community project

TorchGeo is now officially a member of the OSGeo community! OSGeo is a not-for-profit foundation for open source geospatial software, providing financial, organizational, and legal support. We are in good company, with other OSGeo projects including GDAL, PROJ, GEOS, QGIS, and PostGIS. Membership in OSGeo promotes advertising of TorchGeo to the community, and also ensures that we follow best practices for the stability, health, and interoperability of the open source geospatial ecosystem.

All TorchGeo users are encouraged to join us on Slack, join our Hugging Face organization, and join us in OSGeo using any of the following badges in our README:

Lightning Studios support

TorchGeo has always had a close collaboration with Lightning AI, including active contributions to PyTorch Lightning and TorchMetrics. In this release, we added buttons allowing users to launch our tutorial notebooks in the new Lightning Studios platform. Lightning Studios is a more powerful version of Google Colab, with reproducible software and data environments allowing you to pick up where you left off, VS Code and terminal support, and the ability to quickly scale up to a large number of GPUs. All TorchGeo tutorials have been confirmed to work in both Lightning Studios and Google Colab, allowing users to get started with TorchGeo without having to invest in their own hardware.

TorchGeo 0.5.0 Release Notes

0.5.0 encompasses over 8 months of hard work and new features contributed by 20 users from around the world. Below, we detail specific features worth highlighting.

Highlights of this release

New command-line interface

TorchGeo has always had tight integration with PyTorch Lightning, including datamodules for common benchmark datasets and trainers for most computer vision tasks. TorchGeo 0.5.0 introduces a new command-line interface for model training based on LightningCLI. It can be invoked in two ways:

# If torchgeo has been installed
torchgeo
# If torchgeo has been installed, or if it has been cloned to the current directory
python3 -m torchgeo

It supports command-line configuration or YAML/JSON config files. Valid options can be found from the help messages:

# See valid stages
torchgeo --help
# See valid trainer options
torchgeo fit --help
# See valid model options
torchgeo fit --model.help ClassificationTask
# See valid data options
torchgeo fit --data.help EuroSAT100DataModule

Using the following config file:

trainer:
  max_epochs: 20
model:
  class_path: ClassificationTask
  init_args:
    model: "resnet18"
    in_channels: 13
    num_classes: 10
data:
  class_path: EuroSAT100DataModule
  init_args:
    batch_size: 8
  dict_kwargs:
    download: true

we can see the script in action:

# Train and validate a model
torchgeo fit --config config.yaml
# Validate-only
torchgeo validate --config config.yaml
# Calculate and report test accuracy
torchgeo test --config config.yaml

It can also be imported and used in a Python script if you need to extend it to add new features:

from torchgeo.main import main

main(["fit", "--config", "config.yaml"])

See the Lightning documentation for more details.

Self-supervised learning and Landsat

Self-supervised learning has become a dominant technique for model pre-training, especially in domains (like remote sensing) that are rich in data but lacking in large labeled datasets. The 0.5.0 release adds powerful trainers for the following SSL techniques:

BYOL [1]
MoCo [1, 2, 3]
SimCLR [1, 2]

large unlabeled datasets for multiple satellite platforms:

SeCo [1]
SSL4EO-L [1]
SSL4EO-S12 [1]

and the first ever models pre-trained on Landsat imagery. See our SSL4EO-L paper for more details.

Utilities for splitting GeoDatasets

In prior releases, the only way to create train/val/test splits of GeoDatasets was to use a Sampler roi. This limited the types of splits you could perform, and was unintuitive for users coming from PyTorch where the dataset can be split into multiple datasets. TorchGeo 0.5.0 introduces new splitting utilities for GeoDatasets in torchgeo.datasets, including:

random_bbox_assignment: randomly assigns each scene to a different split
random_bbox_splitting: randomly split each scene and assign each half to a different split
random_grid_cell_assignment: overlay a grid and randomly assign each grid cell to a different split
roi_split: split using a roi just like with Sampler
time_series_split: split along the time axis

Splitting with a Sampler roi is not yet deprecated, but users are encouraged to adopt the new dataset splitting utility functions.

GeoDatasets now accept lists as input

Previously, each GeoDataset accepted a single root directory as input. Now, users can pass one or more directories, or a list of files they want to include. At first glance, this doesn't seem like a big deal, but it actually opens a lot of possibilities for how users can construct GeoDatasets. For example, users can use custom filters:

files = []
for file in glob.glob("*.tif"):
    # check pixel QA band or metadata file
    if cloud_cover < 20:  # select images with minimal cloud cover
        files.append(file)
ds = Landsat8(files)

or use remote files from S3 buckets or Azure blob storage. Basically, as long as GDAL knows how to read the file, TorchGeo supports it, wherever the file lives.

Note that some datasets may not support a list of files if you also want to automatically download the dataset because we need to know the directory to download to.

Building a community

With over 50 contributors from around the world, we needed a better way to discuss ideas and share announcements. TorchGeo now has a public Slack channel! Join us and say hello 👋

Now that the majority of the features we've needed have been implemented, one of our goals for the next release is to improve our documentation and tutorials. Expect to see TorchGeo tutorials at all the popular ML/RS conferences next year! We're excited to meet our users in person and learn more about their unique use cases and needs.

Datamodules

Our existing datamodules worked well, but suffered from several performance issues. For the average dataset with 3 splits (train/val/test), we were instantiating the dataset 10 times! All data augmentation was done on the CPU, one sample at a time. A multiprocessing bug prevented parallel data loading on macOS and Windows. And a serious bug was discovered in some of our datamodules that allowed training images to leak into the test set (only affected datamodules using torchgeo.datamodules.utils.dataset_split). All of these bugs have been fixed, and performance has been drastically improved. Datasets are only instantiated 3 times (once for each split). All data augmentation happens on the GPU, an entire batch at a time. And multiprocessing is now supported on all platforms. By refactoring our datamodules and adding new base classes, we were able to remove 1.6K lines of duplicated code in the process!

New datamodules:

GID-15 (#928)
SpaceNet1 (#965)

Changes to existing datamodules:

Only instantiate dataset in prepare_data if download is requested (#967, #974)
Only instantiate datasets needed for a given stage (#992)
Use Kornia for all data augmentation (#992)
Faster data augmentation (CPU → GPU, sample → batch) (#992)
Fix macOS/Windows multiprocessing bug (#886, #992)
Fix bug with train images leaking into test set (#992)
Add plot method to all datamodules (#814, #992)
torchgeo.datamodules.utils.dataset_split is deprecated, use torch.utils.data.random_split instead (#992)
Pass kwargs directly to datasets (#666, #730)
Add random cropping to several datamodules (#851, #853, #855, #876, #929)
Inria Aerial Image Labeling: fix predict dimensions (#975)
LandCover.ai: fix mIoU calculation and plotting (#959)
Tropical Cyclone: CycloneDataModule was renamed to TropicalCycloneDataModule (#815, #846)

New base classes:

Add GeoDataModule and NonGeoDataModule base classes (#992)

Datasets

This release adds a new Sentinel-1 dataset. Here is a scene taken over the Big Island of Hawai'i:

Additionally, all image datasets now have a plot method.

New datasets:

Cloud Cover Detection (#510)
Sentinel-1 (#821)
SpaceNet 6 (#878)

Changes to existing datasets:

Add default root argument to all datasets (#802)
Consistent capitalization of band names (#778)
Many datasets now return float images and int labels (#992)
Chesapeake CVPR: add plot method (#820)
ETCI 2021: fix data loading (#861)
NASA Marine Debris: fix plot warning when model outputs no prediction boxes (#988)
OSCD: images are now stacked channel-wise (#992)
SEN12MS: mask is only single channel (#992)
Sentinel-2: use 10,000 as scale factor (#1027)
So2Sat: rename bands (#735)
Tropical Cyclone: renamed from TropicalCycloneWindEstimation to TropicalCyclone (#815, #846)
Tropical Cyclone: images are RGB, not grayscale (#992)
VHR-10: add plot method (#847)
xView2: remove labels folder (#787)

Changes to existing base classes:

RasterDataset supports band indexing now (#687)
UnionDataset actually works now (#769, #786)
UnionDataset and IntersectionDataset support transforms (#867, #870)
VectorDataset supports multi-label datasets (#862)

Models

Due to the nature of satellite imagery (different number of spectral bands for every satellite), it is impossible to have a single set of pre-trained weights for each model. TorchGeo has always had multi-weight support:

model = resnet50(sensor="sentinel2", bands="all", pretrained=True)

However, this is difficult to extend if you want more fine-grained control over model weights. More recently, torchvision introduced a new multi-weight support API:

With the 0.4.0 release, TorchGeo has now adopted the same API:

model = resnet50(weights=ResNet50_Weights.SENTINEL2_ALL_MOCO)

We also support PyTorch Hub now:

>>> import torch
>>> from torchgeo.models import ResNet18_Weights
>>> torch.hub.list("microsoft/torchgeo", trust_repo=True)
Downloading: "https://github.com/microsoft/torchgeo/zipball/models/weights" to ~/.cache/torch/hub/models_weights.zip
['resnet18', 'resnet50', 'vit_small_patch16_224']
>>> model = torch.hub.load("microsoft/torchgeo", "resnet18")
Using cache found in ~/.cache/torch/hub/microsoft_torchgeo_models_weights
>>> model = torch.hub.load("microsoft/torchgeo", "resnet18", weights=ResNet18_Weights.SENTINEL2_RGB_MOCO)
Using cache found in ~/.cache/torch/hub/microsoft_torchgeo_models_weights

In our previous release, we had 1 model pre-trained on 1 satellite with 1 training procedure. We now have 3 models (ResNet-18, ResNet-50, ViT) trained on both Sentinel-1 and Sentinel-2 for all bands and RGB-only bands with 3 SSL techniques (MoCo, DINO, SeCo), and plans to expand this in the future. Shoutout to Zhu Lab and ServiceNow for publishing these weights!

New models:

Add ResNet-18 and ViT models (#917)

Changes to existing models:

Adopt torchvision's multi-weight support API (#762, #804, #917)
Add support for torch.hub (#917)

New utility functions:

Functions to list, query, and initialize models and weights (#917)

Samplers

Changes to existing samplers:

All random samplers now have a default value for length (#755)

New utility functions:

get_random_bounding_box and tile_to_chips are now public functions (#755)

Trainers

This release introduces a new trainer for object detection, one of our most highly requested features. All trainers now support prediction. Our old trainers only supported ResNet backbones. Our new trainers now support the 600+ backbones provided by the timm library. And all of the new pre-trained models mentioned above are now supported by our trainers as well.

New trainers:

Object Detection: add trainer, add Faster R-CNN (#442, #758)
Object Detection: add RetinaNet and FCOS (#984)

Changes to existing trainers:

Add support for all timm backbones (#854, #918)
Add support for more pretrained models (#917)
Change model argument names (#916, #918, #919, #920)
Support prediction (#790, #792, #813, #818, #819, #939)
Fix plotting file handle leak (#825, #826)
Multi-label Classification: replace softmax with sigmoid (#791)

Transforms

Whenever possible, we try to avoid reinventing the wheel. For data augmentation transforms that aren't specific to geospatial data or satellite imagery, we use existing implementations in popular libraries like:

torchvision (PIL and PyTorch backends)
albumentations (OpenCV backend)
kornia (PyTorch backend)

Until now, we've been fairly agnostic towards data augmentation libraries. However, neither PIL nor OpenCV support multispectral imagery. Because of this, we've decided to use Kornia for all transforms.

Changes to existing transforms:

All transforms are now compatible with kornia.augmentation.AugmentationSequential (#999)
All transforms now take a single image as input instead of a sample dict (#999)
`torchgeo.transforms.Augmentation...

TorchGeo 0.3.0 Release Notes

This release contains a number of new features, and brings increased stability to installations and testing.

In previous releases, not all dependencies had a minimum supported version listed, causing issues if users had old versions lying around. Old releases would also install the latest version of all dependencies even if they had never been tested before. TorchGeo now lists a minimum and maximum supported version for all dependencies. Moreover, we now test the minimum supported versions of all dependencies. Dependencies are automatically updated using dependabot to prevent unrelated CI failures from sneaking into PRs. We hope this makes it even easier to contribute to TorchGeo, and ensures that old releases will continue to work even if our dependencies make backwards-incompatible changes.
