JSC “Latvian Gas” trunk pipeline network and the protected area digital surveying

Upon contract there were 50-meter-wide band for the topography survey, established pipeline burial depth of the recorded communications engineering pipeline crossing location and depth of the pipeline amounted to longitudinal profile discovered, reflecting the engineering communications crossing site.
Earth’s surface and terrain data was determined, and ipeline location and depth determination was used to search for underground communications. Topographic data were prepared in 1:500 scale. The work was done by METRUM in cooperation with a number of JSC Latvian Gas services, plus data specification in accordance with each service’s needs was created.
