Flexible and fit-for-purpose land administration solutions

SOLA supports land registration, cadastre, systematic registration and state land management through open-source desktop applications designed to be flexible, scalable and locally adaptable.

Developed to support responsible governance of tenure, SOLA helps land administration agencies improve transparency, efficiency and service delivery while adapting workflows to national legislation, institutional frameworks and local practices.

The applications can be used independently or as an integrated suite, depending on country needs and implementation contexts.

Why SOLA?

SOLA is particularly relevant for:

• countries seeking affordable and sustainable land administration solutions;
• institutions with limited technical or financial capacity to develop new systems;
• governments looking for adaptable and interoperable platforms;
• programmes supporting fit-for-purpose and incremental land administration approaches.

As an open-source solution, SOLA also supports local ownership and long-term sustainability by encouraging the involvement of local developers and institutions in customization, maintenance and further development.

Technical architecture and standards

SOLA is built on open-source and interoperable technologies and aligned with the Land Administration Domain Model (LADM – ISO 19152), including extensions aligned with the Social Tenure Domain Model (STDM).
