Nex-G Innovations


LiDAR is an emerging and being employed extensively for mapping urban areas, rapid surveys, building 3D city models, monitoring infrastructure projects, mining etc. Skilled map power is play vital role in projects implementation. This training is focused on fundamentals concepts of LiDAR technologies along with hand on exercise on software tools. This includes Principles, Laser physics, Operation, Data formats, Modern trends, Applications, Error analysis, Data processing-concepts and issues, Information extraction, feature extraction, Integration with spectral data, 3D city model generation. Practical assignment covers data format conversion, visualisation, accuracies and error analysis, DEM generation, contour generation, feature extraction like building, powerline and trees, Integration of LiDAR and aerial photograph.
