Learn how to specify the Georeference Settings of your Drawing
Plex-Earth Lite offers the ability to import Google Maps imagery into CAD software. Furthermore, serving as a Viewer, it can automatically reload imagery imports from various providers, made by the full version.
Therefore, georeferencing, i.e. the process of adding geographic information to the drawings, is mandatory in order for the software to know where to place the various images and to relate the aerial and satellite imagery to the various design data and local surveys.
Apart from Plex-Earth though, defining a coordinate system is very important in design in general, for processing spatial data, calculating distances and areas, and for determining various types of information about any given project area.
Adjusting the georeference settings of a drawing with Plex-Earth is a rather simple and easy process. All you need to do is click on the Georeference icon on the "Project" panel.
There are three ways to georeference a drawing:
- By Defining a Coordinate System. This is ideal when a drawing starts from scratch or when a design is already based on a specific Coordinate System.
- By Creating a Custom Georeference. This is ideal for existing drawings that were designed on random coordinates in AutoCAD or BricsCAD and we want to associate a point with an actual georeference point.
- By using CAD's command for Georeference (like GEO in AutoCAD). In this case, Plex-Earth Lite automatically identifies the georeference settings applied and there is no need for further action.
For non-georeferenced drawings, if a user knows where his area of interest is located in Google Earth, they can view the respective Google Maps imagery in CAD right away. In this case, Plex-Earth, by using a reference element, automatically defines the georeference settings. This tutorial shows how.
In the above tutorials, all the necessary information is provided for defining the coordinate system of a drawing.
As georeferencing is mandatory in order to use Plex-Earth, this is the first thing that must be done, before using any of the software’s other features.
We hope that you have found this introduction on how to georeference your drawing with Plex-Earth Lite, helpful. Feel free to contact us at firstname.lastname@example.org for any questions you may still have.
