MERIT DEM: Multi-Error-Removed Improved-Terrain DEM
MERIT DEM là một DEM toàn cầu có độ chính xác cao ở độ phân giải 3 giây cung (~90 m tại đường xích đạo) được tạo bằng cách loại bỏ các thành phần lỗi chính khỏi các DEM hiện có (DEM SRTM3 của NASA, DEM AW3D của JAXA, DEM toàn cảnh của Kính ngắm). DEM MERIT tách biệt độ lệch tuyệt đối, nhiễu dải, nhiễu hạt và … dem elevation elevation-topography merit topography -
MERIT Hydro: Tập dữ liệu thủy văn toàn cầu
MERIT Hydro là bản đồ hướng dòng chảy toàn cầu mới có độ phân giải 3 giây cung (khoảng 90 m tại đường xích đạo) bắt nguồn từ phiên bản 1.0.3 của dữ liệu độ cao DEM MERIT và tập dữ liệu về vùng nước (G1WBM, GSWO và OpenStreetMap). MERIT Hydro chứa kết quả của một … mới dem elevation flow-direction hand hydrography hydrosheds -
