How to create a CRS for Germany?

Requirements

TcpGPS v2.9.0+

Objective

Create a Coordinate Reference System, for Germany, with the new geodesy module included in version 2.9 of TcpGPS.

Details

Create a new project.

Tap on the button on the right of the CRS (Coordinate Reference System) label, to open the screen of predefined coordinate systems.

Tap on the + button to open the screen where the parameters of a new coordinate system are selected.

Select EPSG as Authority.

Enter Germany in the text box, under the CRS label, and tap the > button on the right. It doesn't matter if it's written in upper or lower case letters.

Select the CRS of the working area. The EPSG codes of the most used coordinate systems are:

• EPSG:25831 – ETRS89 / UTM zone 31N

• EPSG:25832 – ETRS89 / UTM zone 32N

• EPSG:25833 – ETRS89 / UTM zone 33N

• EPSG:5676 – DHDN / 3-degree Gauss-Kruger zone 2 (E-N)

• EPSG:5677 – DHDN / 3-degree Gauss-Kruger zone 3 (E-N)

• EPSG:5678 – DHDN / 3-degree Gauss-Kruger zone 4 (E-N)

• EPSG:5679 – DHDN / 3-degree Gauss-Kruger zone 5 (E-N)

Enter Germany in the text box, under the Vertical CRS label, and tap the > button on the right. It doesn't matter if it's written in upper or lower case letters.

Select the CRS EPSG:7837 – DHHN2016.

In the Coordinate operations list, select the first one.

Tap the Download files… button. After the files are downloaded, a message will be shown and the button will be hidden.

Tap the OK button, enter a name for the coordinate system and tap OK again.

The coordinate system will be available in the coordinate system list.

Select the coordinate system and tap the OK button.

The project will be configured with the new coordinate system.
