Smart coordinate transformations in GstarCAD

Automatic coordinate transformation with selectable accuracy variants

The application automatically assigns the correct source CRS in common scenarios — for example, WGS84 when importing from Google Earth (KML/KMZ) — and lets you select a standard target CRS. For each transformation between two coordinate systems, you can choose among multiple variants, each offering different accuracy levels depending on the region. All transformation details, including the method and parameters, can be reviewed before execution.

Editions: Basic Standard Professional
What's included in the feature Smart coordinate transformations

Discover the full potential of this set of tools designed to enhance GIS data integration and editing within GstarCAD.

Automatic coordinate transformation

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.

Transformation variants

For coordinate transformations between two coordinate reference systems, multiple variants can be selected. Each variant offers specific accuracy for a particular area, and all details — such as the transformation method and parameters — can be reviewed.
