Introduction

All CTEP services can be accessed using a web browser. The system’s compatibility has been successfully tested on Windows (8, 10), Linux (Ubuntu 14.x, 16.x) and MacOS X (Yosemite, El Capitan) platforms, using Mozilla Firefox, Chrome, Safari, Microsoft Edge and Opera. Internet Explorer users can also use the application but some errors might occur. Minimum required resolution for system use is 1024x768. The browsers should apriori be set to allow the pop-up windows, JavaScript scripts running and cascade style display (CSS).

• How to access CTEP GeoBrowser and navigate

• How to upload and run your own processor
