The UNIVGA method is <strong>100% online, asynchronous, and written<\/strong> : written courses (PDF and online reading), summary sheets, self-assessment quizzes, and case studies written in a Gabonese or regional context. Unlimited access 24\/7, free progression without imposed schedules, with pedagogical support on demand; the only constraint is to complete the program in <strong>3 calendar months.<\/strong>The tools and standards of the profession (QGIS, ArcGIS, AutoCAD, Covadis, Pix4D, GNSS RTK, FIG, FAO VGGT, ANUTTC\/CNAFRT frameworks) are addressed from a conceptual and methodological perspective: principles, technical choices, document reading, typical deliverables, and traceability.<\/p>\n<p>Upon completion, you will be able to establish a robust cadastral workflow: GNSS preparation, RTK\/Network RTK, PPK, quality control (PDOP, redundancy, multipath), GIS\/CAD integration, and production of enforceable plans and reports. You will know how to align your deliverables with the <strong>requirements of ANUTTC and CNAFRT<\/strong>, in accordance with the Land Code, the DGEPN when applicable, and international best practices (FIG, FAO Voluntary Guidelines \u2013 VGGT), while respecting the OHADA legal framework. This operational expertise immediately enhances your value in land administration, surveying firms, technical services of local authorities, and construction\/real estate projects.
