MERIT DEM: Multi-Error-Removed Improved-Terrain DEM
MERIT DEM – DEM גלובלי מדויק ברזולוציה של 3 שניות קשת (כ-90 מ' בקוטב) שנוצר על ידי הסרת רכיבי שגיאה עיקריים מ-DEMs קיימים (NASA SRTM3 DEM, JAXA AW3D DEM, Viewfinder Panoramas DEM). DEM של MERIT מפריד בין הטיה מוחלטת, רעש פסים, רעש כתמים ו… dem elevation elevation-topography merit topography -
MERIT Hydro: מערכי נתונים של הידרוגרפיה גלובלית
MERIT Hydro היא מפה חדשה של כיוון הזרימה הגלובלי ברזולוציה של 3 שניות קשת (כ-90 מ' בקו המשווה), שמבוססת על הגרסה 1.0.3 של נתוני הגובה של MERIT DEM ומערכי הנתונים של גופי המים (G1WBM, GSWO ו-OpenStreetMap).
