Description
The Christchurch Aerial Semantic Dataset (CASD) comprises aerial imagery at very high resolution over Christchurch, New-Zealand, and reference semantic data for urban objects such as buildings, vegetation and vehicles.
It aims to foster developments of new methods for Earth observation including automatic image classification, object detection, semantic segmentation, semi-supervised learning, etc...
Aerial imagery consists in the Christchurch Earthquake Imagery dataset, released by Land Information New Zealand:
Annotations were produced by ONERA/DTIS on 4 images. Three classes were tagged: buildings (797 objects), cars (2357 objects), and vegetation (938 objects). All objects are given as polygonal bounding boxes (shapefiles) and image semantic masks (rasters).
