Shaded relief image derived from the 1m 2013 TDM of the Autonomous Community of the Basque Country

The image of shaded areas of 1m that represents the orography of the terrain has been generated from the MDT of 1m of 2013. The value of the cells in this image ranges from 0 to 255, with the value 0 being the largest shadow and increasing from black to white. The shaded raster is distributed in a single image in .ECW format for the entire Autonomous Community of the Basque Country in the ETRS89 geodetic reference system and UTM spindle 30 projection.本数据集所采用的1米分辨率阴影区域图像，用于表征地形地势，其生成源为2013年发布的1米分辨率数字地形模型（MDT）。该图像的栅格像元值取值范围为0至255，其中值0对应最深阴影，亮度由黑色至白色逐渐递增。本阴影栅格数据以单幅.ECW格式图像形式发布，覆盖巴斯克自治区全域，采用1989年欧洲大地参考系（ETRS89）与通用横轴墨卡托（UTM）30带投影。
