Custom translations
The following steps describe how you can create your own translation files for the Cartograph app. If you want you can also mail us your translations so that we can put them into the table above!
Step 1: Install Qt Linguist
Translation files can be easily edited with the Qt Linguist application:
Step 2: Download a base translation file
Download one of the translation source files from the table above. It is recommended that you directly download the English version because this version is always up-to-date. Extract the “*.ts” file contained in the downloaded zip file to some location on your computer.
Step 3: Rename the downloaded *.ts file
Now rename the extracted *.ts file matching your language. For “German” the recommended format is for instance “cartograph3.de.ts”, for French “cartograph3.fr.ts”, and so on. As an alternative you can also give the translation file custom names, for instance “cartograph3.mytranslation.de.ts”.
Step 4: Open the translation file in Qt Linguist
Start the Qt Linguist application and open the extracted and renamed *.ts file. Then go to “Edit” – “Translation file settings” and select your translation’s country and language settings:

Step 5: Translate the file
Now you can translate the file. Do not forget to save the translation from time-to-time by pressing the “CTRL+S” keys.
Step 6: Create a *.qm file
Select “File” – “Release” in Qt Linguist. This will create a *.qm file, for instance “cartograph.de.qm”. If you want to share the translation with other users then you can email us your *.qm and *.ts files.
Step 7: Install the *.qm file in the Cartograph app
Copy the *.qm file to the “Translation” directory in the Cartograph app:
- iOS: Use the iOS Files app for copying the file.
- Android: Use the File manager included in the Cartograph app for picking the file.
- macOS: Use the File manager included in the Cartograph app for picking the file.
- Windows: The Cartograph translations directory is located in the Windows “Documents” folder.
Step 8: Select your new language
Go to the Cartograph “Settings” – “Language” and select your new language. It is recommended to restart the app for loading all translations:
- macOS/Windows: Close and open the Cartograph app again.
- Android/iOS: First bring the Cartograph app to the background. Then use the Android/iOS task manager for killing the app.

Dear Cartograph Development Team,
I hope this message finds you well.
I’m a user of Cartograph Maps 3, and I genuinely appreciate the effort and dedication that has gone into developing such a powerful and versatile mapping application.
I’m writing to express my interest in helping with the Simplified Chinese localization of Cartograph.
As a native Chinese speaker with a strong interest in digital maps and mapping technology, I believe I can provide accurate, natural, and context-appropriate Simplified Chinese translations, particularly for the technical terminology and specialized features used in your application.
I understand that high-quality localization involves much more than simply translating words. It requires a good understanding of the software itself, consistent terminology, and careful attention to how users interact with the interface. I would be more than happy to contribute my time and effort to help ensure that the Chinese translation meets these standards.
I would sincerely appreciate the opportunity to contribute to a project that I personally enjoy using. My hope is simply to make Cartograph more accessible and enjoyable for Chinese-speaking users.
If you would be open to accepting translation contributions, please let me know how I might get involved. I would gladly work with whatever translation files, tools, or guidelines you prefer.
Thank you very much for your time and for your continued work on Cartograph. I look forward to hearing from you.
Best regards
