Digital Land Model (Resolution 2 m) – Oliveira do Hospital – 2011

Digital Land Model of the Municipality of Oliveira do Hospital executed from an aerophotogrammetric coverage with spatial resolution of 10 cm (GSD). 4-band spectral resolution (RGB and NIR) and 16-bit radiometric resolution. The aerophotogrammetric coverage was carried out in 2011 using the digital aerial camera DMC 129, with a focal distance of 120 mm. This information is found in the reference system PT-TM06/ETRS89 and the vertical reference is the Cascais Helmert 38 Altimetric Datum and the applied geoid model is GeodPT08.本数据集为奥利韦拉-杜什努什市的数字土地模型（Digital Land Model），基于空间分辨率达10厘米（地面采样距离，GSD）的航空摄影测量覆盖作业生成，具备4波段光谱分辨率（红、绿、蓝及近红外，RGB和NIR）与16位辐射分辨率。该航空摄影测量覆盖作业于2011年完成，采用数字航空相机DMC 129，相机焦距为120毫米。本数据集采用的参考坐标系为PT-TM06/ETRS89，垂直基准为卡斯卡伊斯赫默尔特38高程基准面，所使用的大地水准面模型为GeodPT08。
