How do you Georeference in GIS?

The general steps for georeferencing a raster dataset are:

  1. Add the raster dataset that aligns with the projected data.
  2. Add control points that link known raster dataset positions to known positions in map coordinates.
  3. Save the georeferencing information when the registration is satisfactory.

How does georeferencing work in ArcGIS Pro CAD?

Georeferencing is the process of spatially adjusting a CAD drawing without actually changing the original source data. In ArcGIS Pro, this is performed by linking points in the CAD drawing to known geographic coordinates.

How does ArcGIS for desktop transform CAD data?

In ArcGIS for Desktop this is performed by registering arbitrary points in the CAD drawing to known geographic coordinates. Once you have georeferenced a CAD dataset, subsequent ArcMap sessions transform the dataset in memory on the fly while the source data remains unchanged on disk.

Can You georeferencing a CAD dataset to a map?

You can choose any CAD feature layer in the map that derives from the same dataset—the transformation is applied to all child feature classes. Once you have georeferenced a CAD dataset you can add its feature classes to the map document at any time and they are constrained by the same control points.

What is the purpose of georeferencing CAD data?

The purpose for georeferencing a CAD dataset is to accurately overlay the CAD drawing with existing spatial data without skewing its geometry. If a more complex transformation is needed, you can load the data into a geodatabase and use the Modify Features pane.
