Frequently asked questions

The platform is intended for professional surveyors and authorized professionals who need verified access to CORS services, official Ghana Grid values, and related cadastre workflows.

Registered users can manage surveying jobs, request RINEX or VRS data, track submissions, make secure payments, and download receipts—subject to verification and applicable fees.

Some stations now use new active codes while retired codes are phased out. Use the station lookup on the home page to map old codes to new ones before configuring receivers or documentation.

Email may be optional depending on portal policy, but providing a valid email is strongly recommended for password recovery and important service notices.

Submissions are validated and reviewed under SMD quality control processes. Field RINEX and prescribed forms may be required so results align with national standards.

The service is operated in collaboration between GMX Systems Ghana Ltd., the Ghana Lands Commission, and LISAG, with monitoring and processes aligned to national cadastre requirements.
