The UNIVGA method is <strong>100% online, asynchronous, and written<\/strong> : written courses (PDF and online reading), summary sheets, self-assessment quizzes, and written case studies. Students progress entirely at their own pace, with pedagogical support on demand, and have permanent access 24\/7, with the only constraint being to complete the program within <strong>3 months maximum.<\/strong>Professional tools (QGIS, ArcGIS, AutoCAD Civil 3D, Covadis, Pix4D, GNSS RTK) are approached from a theoretical and methodological perspective: principles, data flows, typical deliverables, and reading technical documents.<\/p>\n<p>At the end of the course, you will be able to structure and control a polygonal path, estimate and compensate errors using least squares, calculate reliable coordinates, azimuths, and altitudes, and then establish deliverables that meet the expectations of administrations and project owners. The impact is direct for land administration services, surveying firms, local authorities, and construction\/real estate companies: improvement of geometric quality, traceability of controls, and regulatory compliance. The <strong>Professional Certificate UNIVGA<\/strong> certifies operational skills that can be immediately mobilized for cadastral, urban planning, and construction project missions, and enhances your profile with recruiters and clients in French-speaking Africa. You will strengthen your autonomy in preparing ANUTTC\/CNAFRT files, checking tolerances, critically reading technical reports, and producing georeferenced topographic plans, in line with best practices from FIG and the FAO's Voluntary Guidelines (VGGT).<\/p>","protected":false},"excerpt":{"rendered":"<p>Master leveling, polygoning, and topometric calculations to produce plans, altitudes, and placements that comply with ANUTTC\/CNAFRT requirements.
