Advanced True Orthophoto from Photogrammetry and LiDAR Integration

Advanced True Orthophoto from Photogrammetry and LiDAR Integration

This flythrough over The University of Calgary shows the successfull integration between LiDAR data and high resolution true-orthorectified aerial photographs. This is part of a PhD research that involves integration of LiDAR, Photogrammetry, and GIS for improved realistic 3D visualization. Well there is a number of sw used from point to point. The Building DBM modelling was semi-automated using an extension ...

Visualisation of Vegetation GIS Mapping using LiDAR

Visualisation of Vegetation GIS Mapping using LiDAR

Building up from a LiDAR point cloud, an digital elevation model is built from ground points which enables generation of watercourses and contours. Non-Ground laser strikes are then visualised for a highly forested environment in which a number of significant tall trees are located. Those trees exceeding 60 metres in height are then identified by a bright red colour, and ...

Is photogrammetry as accurate as lidar?

Is photogrammetry as accurate as lidar?

Elmer Bol, new director of reality capture at Autodesk and founder of Alice Labs, spoke at SPAR Europe in November about the increasingly sophisticated technology that is allowing the accuracy of point clouds created by photogrammetry to approach the accuracy of terrestrial lidar and laser scanning.

3D model of a real forest from airborne LiDAR

3D model of a real forest from airborne LiDAR

This is a fly through 3D digital model of a real forest (Bois noir forest Barcelonnette, France) from LiDAR derived forest inventory parameters and aerial ortho-image. The model was developed as part of my research on ‘Forest inventory parameters and Carbon mapping from airborne LiDAR’. High density, small footprint discrete airborne LiDAR is capable of capturing rich structural information of ...

LiDAR Processing in Global Mapper 15

LiDAR Processing in Global Mapper 15

This video explore the use of LiDAR data in Global Mapper. A key development priority over recent releases, LiDAR processing is now a major functional component of the software. While the standard version of Global Mapper includes some basic LiDAR processing capability, the new LiDAR module adds a powerful set of tools for working with point cloud datasets and for ...
