Coordinates transformation in GstarCAD Updated V9

Calculate geometric transformations of the objects in the import and export processes in GstarCAD

Spatial Manager™ for GstarCAD will calculate geometric transformations of the objects in the import and export processes, which will depend on the chosen Coordinate System (CRS) for the source and target data

The user can choose the appropriate CRSs from a complete CRS catalog or from a list which includes the most recent used CRSs

Unified CRS system

Use the same tools (the CRS Catalog essentially) to assign the Coordinate Reference System to a drawing, or to define the CRSs to the source and the target when performing the import/export processes

Smart Transformations

The application helps when entering any configuration setting. For example, if you are importing from Google Earth (KML/KMZ), the source CRS is automatically set to WGS84 and the target CRS can be set to a standard projected CRS

Updated Coordinate Systems objects list

The objects list includes more than 15000 Projections, Ellipsoids, Coordinate Systems, Coordinate Transformations, etc. for all the areas and geographic segments of the Earth. This list is often extended, revised and updated. The Catalog includes a set of practical tools to filter, search or group the most recent used CRSs

Custom grid files

The application allows loading custom grid files for NTv2 coordinate transformations

Custom Coordinate Systems New V9

This function allows you to define your own Coordinate Systems to suit your specific needs

Transform drawings Coordinate System

Transform the Coordinate System (CRS) of a whole drawing or a set of selected objects, which automatically creates a new drawing including geometrically regenerated objects from the current drawing according to the chosen transformation between two CRSs
