Importing GIS Data Types

Interoperability tools provide a number of methods for sharing geospatial data. They allow to:

The Import module allows for the exchange of graphical data and associated non-graphical database information of a variety of GIS file formats.

There are several ways to customize a GIS file import. It is possible to control the spatial extents of the area being imported, the symbology of the imported elements, and what database attributes will be transferred. Multiple files can be imported at once.

A note about working units

Data will be imported and scaled according to the current working units. So, if your data is in US survey feet and your DGN is set to Metric working units, then the data being imported will scale to be in metric units.

Be very careful of the difference between US Survey feet and international feet.

These units are almost equivalent. A US Survey foot is defined as being .3048006 meters, while an imperial foot is defined as being .3048 meters. Such a small difference scales to a large error when dealing with the large distances encountered in mapping projects.

For best results, set your working units to be the same as the units defined in the coordinate system associated with your design file. For further information, see the MicroStation Help under Selecting a Geographic Coordinate System > Design File Settings dialog Working Units.
