Géodésien en Afrique

[Ministry of Lands,Housing and Urban Development @ministry_lands]

Mr. Cyril Romieu the Project Manager of the Uganda Geodetic Reference Frame (UGRF), in his presentation at the UGRF Workshop this morning, started by introducing the project. He emphasized that the project is more than just another CORS (Continuously Operating Reference Stations) network. He detailed its development, current impact, and future direction in Uganda.

The UGRF began with Phase I, which established 12 CORS stations providing high-precision GNSS data. These stations are equipped with advanced tools, including Leica GR50 receivers and solar panels for uninterrupted power supply. Phase II expanded the network to 40 stations, ensuring broader national coverage and improved accuracy, achieving better than 5 cm precision across the country. A National Control Center (NCC) and a mirrored backup center were established for centralized monitoring, data processing, and delivery.

Romieu highlighted UGRF’s role in providing free access to geodetic data through online tools at https://t.co/6ey9ox7aag, enabling users to process and retrieve high-quality spatial information. The UGRF also supports critical national needs such as land administration, disaster monitoring, infrastructure planning, and environmental management. Its integration with private CORS networks and alignment with international standards enhance its usability and impact.

The UGRF contributes significantly to Uganda’s development by supporting scientific research, mitigating risks from natural disasters like landslides and floods, and facilitating weather forecasting. It also bolsters Uganda’s international stature, with data from select stations submitted to the International GNSS Service (IGS) for global geodetic studies.

Romieu addressed existing challenges, such as limited redundancy, insufficient station density, and the need for improved transformation parameters. He recommended expanding the network, updating the passive database, and enhancing the training and capacity of monitoring teams. Legal frameworks and collaborative tools were also suggested to ensure sustainable use and management.

He concluded by emphasizing UGRF’s commitment to serving Uganda’s development needs while aligning with global geospatial standards. The network’s continued evolution will further support national growth and resilience.

1/En lisant le @Challenges consacré au classement 2021 des fortunes de France, je tombe, parmi les "meilleures progressions", sur Daniel Derichebourg, qui va sa fortune augmenter de 203% en une année. Et ça m'a fait penser à autre chose, qui s'est passé au printemps 2020 :

Excellent French public campaign about the side effects of Covid vaccines

Nous avons encore le contrôle à titre individuel (vaccination et gestes barrières) et politique (tester-Tracer-Isoler-Séquencer et contrôle aux frontières). Saurons-nous prendre nos responsabilités ? https://t.co/a32slLefKe

Chaque jour, 33 000 jeunes arrivent sur le marché du travail en Afrique, et 12 000 d’entre eux ne trouvent pas d’emploi.
Parce que les solutions pour leur avenir sont à chercher ensemble, l’Afrique et la France ont rdv à Montpellier en octobre ! 🌍🇫🇷🇨🇮

Here the outstanding beauty of Murchison Falls. The view of the falls taken from a drone (courtesy Madhvani group) is breath taking. This natural heritage, entrusted to Uganda to preserve & protect, belongs to all humanity. This is Uganda's real gold that can be mined forever!
