THE USE OF 3D DEPTH CYCLORAMAS IN MUNICIPAL PROCESSES

Abstract. The use of digital panoramic imagery in processes at municipal and cadastral authorities has become common over the last decade. Applications are found among situational awareness, inventory of public areas, real estate valuation, assessment of permits and inspecting security risks. More and more the imagery is being used for measuring and map making. To enhance the quality and effectiveness of the applications and to improve the user friendliness of measuring and map making, a new dimension has been added to the panoramic images: the 3rd dimension. The principle and process behind these so-called Depth Cycloramas is briefly explained and their possibilities in municipal practice are demonstrated. Differences with the employment of LiDAR point clouds concerning precision and possibilities are detailed. Attention is paid to the excellent possibilities offered by Depth Cycloramas for projecting 2D and 3D maps and designs, for stereo viewing and for deriving detailed 3D information of object geometry and object texture.
