Pick Draft, Standard, or High Quality
Choose the right mosaic quality for your case.
Use this when
You are about to generate a mosaic and want to choose the right resolution for your situation.
Before you start
The three resolution buttons appear in the bottom control bar of the Mosaic view: 0.5 m, 0.25 m, and 0.1 m. These correspond to the labels draft, standard, and high in the app. The selected button is highlighted; the default is 0.25 m.
The three options
| Button | Label | One pixel covers |
|---|---|---|
| 0.5 m | draft | 50 cm × 50 cm of bottom |
| 0.25 m | standard | 25 cm × 25 cm of bottom |
| 0.1 m | high | 10 cm × 10 cm of bottom |
When to use each
0.5 m (draft)
Use this to get a quick overview of a large area or to check whether the recording will produce a usable mosaic at all. Generation is faster and uses less memory. Fine structure is not visible at this resolution, but you can see large features — channels, weed beds, hard-bottom patches.
0.25 m (standard)
The default. Balances detail and speed for most survey sizes. Good for typical lake or river surveys where you want to identify structure and share the result.
0.1 m (high)
Use this when you need to see fine bottom detail — small rocks, subtle texture changes, or closely spaced targets. Generation takes noticeably longer. For very large survey areas, the pipeline may automatically reduce the actual resolution if the resulting grid would exceed the pixel budget; the status bar shows the actual meters-per-pixel used after generation completes.
What the status bar shows after generation
The bottom of the screen shows the actual grid dimensions and resolution, for example: 2840×1960 @ 0.10 m/px. If you requested 0.1 m but the area was very large, the actual value may be higher (coarser) than requested.
If it does not work
- Resolution buttons are greyed out during generation — wait for the current run to finish or click Cancel, then change the setting and regenerate.
- Requested 0.1 m but got a coarser result — the survey area was large enough to exceed the pixel cap. Use 0.25 m for large areas, or split the survey into sections.
