SCAMIN is an attribute (defined by the IHO S-57 standard) that can be used to tag ENC
chart features to be suppressed above a certain display scale.
The primary function of SCAMIN is to declutter the chart display, enabling the operator to
focus on the most useful navigational information for the current display scale. As the chart
display is decluttered, SCAMIN also helps increase the chart re-draw performance.
The application of the attribute by the producer of the ENC data is optional; some chart
providers may not apply SCAMIN. Also, it may not be available consistently across different
ENC charts.
