TopoDOT™ is a high performance MicroStation™ application for importing and extracting topography and models from point clouds, calibrated images and related data. TopoDOT™ offers a balance of automation and streamlined user interaction designed to maximize productivity while assuring quality. TopoDOT™ facilitates the use of point clouds and calibrated images across Survey, Design, Engineering, Construction and Management operations to enhance quality, improve efficiency and increase profitability. TopoDOT™ offers complete access to all open 3D image data formats such as point cloud "LAS" from all systems and sources. Proprietary formats are accommodated at every opportunity. TopoDOT™ makes it easy to integrate aerial views from many sources such as Google™, Bing™, etc., or your own custom aerials into your 3D image data. TopoDOT™ imports "calibrated" images into the MicroStation™ environment such that these images, the point cloud data and the CAD elements are mapped to a common perspective view. TopoDOT™ offers a tool suite developed for extracting ground topography quickly, easily, and accurately from point clouds and calibrated images. Breaklines, elevations, station cross-sections, and other DTM components are extracted in MicroStation™ according to project format requirements.
