INCREASED_RESOLUTION | boolean | Load the DEM at twice the resolution. | False |
Loading the DEM at a higher resolution skips an interpolation step, making the interpreted elevation model more accurate. This improves flow throughput in very small channels and reduces grid flow artifacts, at the cost of additional calculation time.
Notes
- This attribute only works for a grid cell size <= 0.5m.
- This attribute is False by default.
- In the advanced settings step of the Water Overlay Wizard, this attribute can also be (de)activated.
