Detect apartments, houses, industrial buildings and sheds in satellite images.
Building Detection identifies buildings in satellite images. The block can detect buildings of various sizes in images with ground sampling distance (GSD) of 0.55m or less. The output is provided as JSON with details of detected bounding boxes coordinates; and the image showing bounding boxes on the buildings. The block is trained on a data-set obtained from South-Eastern Asia.

Note: This block needs to be used without Raster Tiling. Pléiades Reflectance (Download) is currently not supported.
The algorithm uses deep learning techniques and CNN-based detection architectures to achieve the computer vision objective. The solution is built in Python and uses Tensorflow at backend as deep learning framework. The algorithm processes satellite images with no restrictions on image dimensions.
The use cases are Urbanization monitoring, Infrastructure monitoring, Urban Planning & Design, Construction.
