Geometrically adjusted lines
收藏资源简介：
Each boundary line between the municipalities is registered in the Central Registry of Cartography (RCC) according to its Registration Sheet. The associated legal documentation is constituted by a Demarcation Act with the operation carried out, to recognize the terminus line and indicate the landmarks carried out by the Municipalities involved and the IGN. The technical documentation is made up of the field notebooks of the topographical surveys carried out and the plans of the time. The geometry of the line has been adjusted according to the description of the registered legal title, by comparison with aerial orthophotography, digital terrain model or other cartographic sources and, where appropriate, based on the registered technical documentation (field notebooks and plans)
