Application DGN2SHP Converter

CAD (Computer-Aided Design) vs GIS (Geographic Information System): CAD, a software of graphical representations of physical objects, drawing files and GIS with capabilities to perform spatial operations in a Database with graphics associated with alphanumeric data (ids and attributes). The difference between these two methodologies is noticeable. The information acquired in GIS has significantly improved in terms of information quality, constituting a major step towards the migration of CAD technology to GIS. A migration without any loss of information between technologies is only possible if tools/applications are developed that allow this transformation of CAD information (DGN) into GIS (SHP), according to an existing Catalog.

The development of the DGN2SHP_Converter application was directed to user interaction, a simple and intuitive app and quick access to the necessary data input and mapping of information, as well as the visualization of all the steps performed during the execution of the conversion of DGN into SHP.

A specific application software composed of a set of instructions written in a high-level programming language (3rd generation) Python and C++ and libraries such as GDAL (Geospatial Data Abstraction Library), shapefile and csv for handling shapefiles and csv files.

The application requires user intervention for the selection of the DGN file/s that you want to convert to SHP. The output of the application is automatically selected, but can be changed by the user. Similarly, the mapping file is selected, the central file of the application, responsible for mapping the information in CAD to the corresponding information in GIS, a mapping of attributes (type, level, color, style and thickness) for a feature, nominal.
