The Geodetic Infrastructure and Service specializes in preparing photo control marks (premarks) for aerial survey input, adhering to established surveying standards. This involves meticulous metadata preparation for various geodetic surveys, ensuring accuracy and reliability in the data collected. In addition to this foundational work, the department is responsible for planning, coordinating, and controlling geodetic operations across the country.
One of the key functions of the Geodetic Infrastructure and Service is the management and maintenance of the National Continuously Operating Reference Stations (CORS) network. This includes updating and organizing the geodetic station control center database, as well as establishing and expanding the network to enhance its coverage and reliability. The department continuously monitors and studies the impacts of land movement and water resource dynamics on the geodetic network, making necessary adjustments to ensure the integrity of the data.
Furthermore, the department calibrates geodetic equipment, ensuring precision in measurements and data collection. It also organizes laboratory inspections, maintenance, and adjustments to equipment to uphold the highest standards of accuracy.
Enhancing, expanding, maintaining, and modernizing the geodetic reference frame and datum, which serves as the country’s geodetic system, is a critical aspect of the department’s work. Research and development activities are integral to this process, facilitating advancements in geodetic methodologies and technologies that support national and regional surveying initiatives.
