Case study

Classifying surface cover types and mapping rainwater volumetric capacity

Classifying surface cover types of urban areas (green areas, uncovered areas, areas with artificial surface cover) and modelling rainwater ditches, determine rainwater volumetric capacity.

Goals

Classifying surface cover types of urban areas (green areas, uncovered areas, areas with artificial surface cover) and modelling rainwater ditches, determine rainwater volumetric capacity.

Tasks

Perform image classification and segmentation using the fusion of high resolution multispectral aerial digital images and LiDAR data, producing surface cover maps.Identifying and modelling rainwater ditches based on LiDAR data, producing runoff models.

Applied technologies

End products

Potentials of the produced database

Using the data we can identify urban areas where the risk of high rainwater load is large.

The database supports runoff models and the planning of drainage systems.
