DEM 在ArcMAP 和QGIS中显示数据不一样?
arcgis中打开DEM数据的正确方式
- load DEM
- data management => raster property => raster statistics
- project and display
calculate Slope from DEM, using ArcGIS
- Raster surface -> slope
- degree
-
default
QGIS中打开DEM
- raster property
- style => load min/max => extract actural (slower)
calculate Slope from DEM, using QGIS
- raster => analysis => slope
- change the style again
- load min/max => load, actural values.
