Tridex does the work for you in automatic mode, reducing manpower, costs and delivers more accuracy than manual methods. For special analysis or modelling, the semi-automatic mode has a user-friendly interface equipped with built-in editor as authoring tool. This eases the task of making corrections or changes as we generates the desired data, allowing the user to make on-the-fly adjustments to the attributes and level of detail (LOD) of the selected buildings to be reconstructed. The quality and accuracy of architectural information such as building footprints is increasing in importance as building and land development projects become more complex, time consuming and cost-intensive.
