Polygonal elements associated with the geometric description of the terrain of the Harmonised Topographic Base at scale 1:5,000 of the Autonomous Community of Cantabria in 2007

The dataset BTA_5000_2007_73_Relieve_pol is made up of surface relief elements (sloping abrupt change surfaces), which complete information from othersets of point and linear data to form a model of representation of elevations and relief elements throughout the mapped area in the series.The complete data series of which it forms part is composed of the following Spatial Data Sets that together form the series (*Names may vary slightly depending on the download or access format. **There may be sheets that do not necessarily require the presence of all data sets):BTA_5000_2007_30_PointsRef_pun: specific elements describing the geodetic reference equipmentBTA_5000_2007_31_Hidrografia_pun: point elements associated with hydrographyBTA_5000_2007_32_EdiPobCons_pun: specific elements associated with population centers and constructionsBTA_5000_2007_33_RedViaria_pun: specific elements associated with the road networkBTA_5000_2007_34_RedFerro_pun: point elements associated with the railway networkBTA_5000_2007_35_Relieve_pun: point elements associated with the geometric description of the terrainBTA_5000_2007_36_ServInst_pun: point items associated with services and facilitiesBTA_5000_2007_37_NomGeo_pun: point elements associated with toponymyBTA_5000_2007_50_ServInst_lin: linear elements associated with services and facilitiesBTA_5000_2007_51_EdiPobCons_lin: linear elements associated with population centers and constructionsBTA_5000_2007_52_RedViaria_lin: linear elements associated with the road networkBTA_5000_2007_53_RedFerro_lin: linear elements associated with the railway networkBTA_5000_2007_54_Hidrografia_lin: linear elements associated with hydrographyBTA_5000_2007_55_CubiertaTer_lin: linear elements associated with the sketch of land occupationBTA_5000_2007_70_EdiPobCons_pol: polygonal elements associated with population centers and constructionsBTA_5000_2007_71_RedViaria_pol: polygonal elements associated with the road networkBTA_5000_2007_72_Hidrografia_pol: polygonal elements associated with hydrographyBTA_5000_2007_73_Relieve_pol: polygonal elements associated with the geometric description of the terrainBTA_5000_2007_74_Relieve_lin: linear elements associated with the geometric description of the terrainBTA_5000_2007_75_ServInst_pol: polygonal elements associated with services and facilitiesBTA_5000_2007_76_DeckTer_pol: polygonal elements associated with the sketch of land occupation数据集BTA_5000_2007_73_Relieve_pol由地表地貌要素（倾斜突变面）构成，其通过补充其他点状、线性数据集的信息，构建出本次测绘区域内高程与地貌要素的系列化表达模型。该数据集所属的完整数据系列由以下空间数据集共同组成（*名称可能因下载或访问格式略有差异；**部分图幅未必需要包含全部数据集）： 1.
