Calculate transformation parameters and transformation of coordinates between two coordinates systems.
TransLT is designed to calculate the transformation parameters and the transformation of coordinates between two coordinates systems in a fast and practical way. To make it easy to operate with the multitude of existing reference coordinates systems, TransLT contains a module that extracts information from EPSG database. The program interface is intuitive, easy to use, the data can be imported from txt or csv files, and it allows saving the modification for each step of the transformation. TransLT is an application which offers the following three major functionalities: - the calculation of transformation parameters between two coordinates systems; - the transformation of coordinates between two coordinates systems; - drawing of polygons, paths or points in Google Earth. The calculation of transformation parameters between two coordinates systems can be performed in the following situations: - 1D transformation (calculation with 5 or 1 parameters); - 2D transformation (calculation with 4, 5 or 6 parameters); - 3D transformation (calculation with 7, 8, 9, 10 or 12 parameters). For each set of calculated parameters calculation reports are generated offering the user information about the quality of the calculated values. The transformation of coordinates between two coordinates systems can be done by applying 1D, 2D or 3D transformation or by applying a multiple transformation in steps. The steps of a multiple transformation can be used to make the following coordinates operations: - coordinates conversions (including using a map projection); - polynomial transformations; - transformations using grid files (files containing corrections values); - transformations with parameters: 1D, 2D or 3D; - transformations with user defined formula. The multiple step transformations (which contain many successive transformations) can be saved and used later, with the possibility of applying them directly on a file using the contextual menu from Windows Explorer. Supported conversions: - Geographical coordinates to Geocentric cartesian coordinates (X, Y, Z); - Geocentric cartesian coordinates (X, Y, Z) to Geographical coordinates; - Geographical coordinates to Plane coordinates (N, E) according to the selected projection; - Plane coordinates (N, E) to Geographical coordinates according to the selected projection.
