Coordinate Reference System Overview
In its simplest form, a coordinate reference system (CRS) is used to establish a relationship between Cartesian and Geodetic coordinates.
The CRS of a project is defined when you create a new project (see Creating a Project). There, you can select from a long list of pre-defined CRS in the Standard CRS Table. At any time during your project, you can change the CRS of the project (see Configure a Project).
Note: The system will prompt you to configure the CRS when you launch a project without specifying the project CRS. A valid project must have its CRS defined or at least the X/Y units specified.
Note: The supported coordinate formats for Lat/Long are:
- Decimal degrees : DDD.ddddd e.g. 112.12312E
- Degree-Minute-Seconds : DDDMMSS.ss e.g. 1121234.56E
Creating custom CRS
A custom CRS can also be created (with the correct format) and used in Insight. For more information on the acceptable syntax and format of the custom CRS file, see Defining a custom coordinate reference system (CRS).
Converting CRS when importing
Now that you have your project CRS defined, anything you import into the project will be prompted to use that CRS.
See the following links to convert from the file CRS to the project CRS:
