Ways to access this function :
1. Importing Vector Data
(1) Of CAD type
Because data in this type contains several layers and maybe different objects have different styles, so we provide several importing mode for different need.
First you can import it as CAD dataset which will keep all its original styles. And also you can select Union Layers option to merge all the original layers into one CAD dataset, or clear this option to import each layer into a CAD dataset.
Or you can import it as GIS dataset which will lose all the original styles but sort different kinds of objects into different datasets. Also in this condition you can select Union Layers option to merge objects of one type in all layers to one GIS dataset, or clear this option to import each layer into GIS dataset individually.
(2) Of other types
Commonly you may want to import data of this type to GIS dataset. Just input the file and the system will generate datasets according to object types it has.
2. Importing Raster Data
It is easier to import a raster data than a vector data for it has not such many parameters. But it should be noted that an imported raster data has no coordinate information, so you should register for it after imported, to assign real-world coordinates for it. But if the raster data has real-world coordinate with it such as a TIFF data, you can select a reference file for it in the Advanced settings, and then the system will set coordinates for the raster automatically. For more information about the reference file, please refer to Reference File for Images in Geographic Coordinate System
