# DeepTrees Halle DOP20 labels + imagery

[![DOI](https://huggingface.co/datasets/huggingface/badges/resolve/main/dataset-on-hf-sm.svg)](https://doi.org/10.57967/hf/4213)


This is a sample dataset for model training and fine-tuning in tree crown segmentation tasks using the [DeepTrees](https://deeptrees.de) Python package. 

Overview of subtiles with sample of labels:

## Dataset Details

We have taken a single Multispectral (RGBi) 2x2 km DOP20 image tile for Halle, Sachsen-Anhalt, from LVermGeo ST for the year of 2022. 

**TileID from source:** 32_704_5708_2

We then sliced the tiles into subtiles of 100x100m, resulting in 400 subtiles. These are provided as 4-band raster `.tif` files.

We are manually labelling tree crowns in these subtiles based on an entropy-based active learning approach. The label classes have been provided below. 

The labeling is done in QGIS and the polygon vectors are provided as  ESRI-shape `.shp` files per subtile.

### Label Classes

**0** = tree

**1** = cluster of trees

**2** = unsure

**3** = dead trees (haven’t added yet)
