GeoSR-Bench
π§ Dataset Upload in Progress
GeoSR-Bench is currently being uploaded and reorganized.
Some files, metadata, and subsets may still be incomplete or subject to change.
Dataset Description
GeoSR-Bench directly connects super-resolution (SR) with downstream Earth monitoring tasks, moving beyond conventional fidelity-based evaluation. It comprises spatially co-located, temporally aligned, and quality-controlled image pairs from about 36,000 locations across diverse land covers, spanning spatial resolutions from 500 m to 0.6 m. It is designed to evaluate whether improved image resolution from SR models translates into better downstream performance for tasks such as land cover segmentation, infrastructure mapping, and biophysical variable estimation. GeoSR-Bench includes two cross-platform super-resolution tasks:
- MODIS β Landsat-8
- Sentinel-2 β NAIP
For each task, the dataset is organized into two types of subsets:
Super-resolution-only datasets
These subsets include paired lower-resolution and higher-resolution remote sensing images without downstream task labels. They are designed for training SR models.Downstream task datasets
These subsets include paired lower-resolution and higher-resolution images together with task-specific labels. They are designed to finetune SR models and evaluate whether super-resolved images improve downstream Earth monitoring tasks, such as land cover segmentation, infrastructure mapping, and biophysical variable estimation.
Each sample may contain:
- A lower-resolution image
- A higher-resolution reference image
- A downstream task label, when available
- Metadata, when available
GeoSR-Bench is intended to support research on task-aware super-resolution, cross-platform learning, and remote sensing foundation models.

Split Files
Each subset includes a CSV file describing the image paths and data split.
SR-only datasets are intended for training super-resolution models and do not have predefined train/validation/test split files.
For downstream task datasets, the CSV contains:
LR image,HR image,Label,split
DownstreamDatasetName/s2/s2_0.tif,DownstreamDatasetName/naip/naip_0.tif,DownstreamDatasetName/label/label_0.tif,training
DownstreamDatasetName/s2/s2_1.tif,DownstreamDatasetName/naip/naip_1.tif,DownstreamDatasetName/label/label_1.tif,validation
DownstreamDatasetName/s2/s2_2.tif,DownstreamDatasetName/naip/naip_2.tif,DownstreamDatasetName/label/label_2.tif,test
Data Fields
| Column | Description |
|---|---|
LR image |
Path to the lower-resolution input image |
HR image |

Label |
Path to the downstream task label |
split |
Dataset split: training, validation, or test |
File Formats
- Images are stored as GeoTIFF files (
.tif). - Labels are stored as GeoTIFF files (
.tif). - Metadata files, when available, are stored as JSON files (
.json). - Split files are stored as CSV files (
.csv).
GeoTIFF files retain geospatial metadata such as coordinate reference system, transform, resolution, and spatial extent.
Usage
You can read the split CSV using Python:
import pandas as pd
csv_path = "DownstreamDatasetName/DownstreamDatasetName_split_all.csv"
df = pd.read_csv(csv_path)
train_df = df[df["split"] == "training"]
val_df = df[df["split"] == "validation"]
test_df = df[df["split"] == "test"]
print(len(train_df), len(val_df), len(test_df))
For SR-only datasets, use the LR image and HR image columns:
sample = train_df.iloc[0]
lr_path = sample["LR image"]
hr_path = sample["HR image"]
print(lr_path)
print(hr_path)
For downstream task datasets, use the LR image, HR image, and Label columns:
sample = train_df.iloc[0]
lr_path = sample["LR image"]
hr_path = sample["HR image"]
label_path = sample["Label"]
print(lr_path)
print(hr_path)
print(label_path)
You can read GeoTIFF files using rasterio:
import rasterio
with rasterio.open("DownstreamDatasetName/s2/s2_0.tif") as src:
image = src.read()
crs = src.crs
transform = src.transform
print(image.shape)
print(crs)
print(transform)
