Implantação e homologação de vértices geodésicos na cidade de Ariquemes-RO

Abstract

All Brazilian cities considered use for medium or large size must have a reliable cartographic base and a consistent geodetic reference network, including landmarks and level references (RNs). The Implantation of geodetic points, as level references, has prerequisite basic knowledge in geodesy areas, topography and cartography. The geodetic vertices to be approved must follow procedures required by current standards, such as standards for geodetic surveys issued by IBGE (Brazilian Institute of Geography and Statistics), the construction and testing of data must also be strictly followed, suggested by standards. For Ariquemes-RO municipality, two geodesic axis were implanted: a forced centered geodetic pillar (planimetric and ellipsoidal altitude coordinates) and a pyramid trunk shape in relation to a level indication, both built in public area, near Ariquemes municipality. For GNSS screening, with no intention providing approval geodesic pillar, multifrequent receivers and data collected using IBGE in RINEX format files were used. A level reference has been constructed and will be allowed from geometric level with a normal limited altitude from official vehicles of Brazilian Geodetic System (SGB) high precision altimeter network. With this work, you can define starting points for a municipal cadastral registration network, enabling quality work as technical-scientific applications as testing for a future cartographic projection system, exclusive to municipality (determination of ideal parameters).
