You specify the zoom range to display a layer at, such as between 1 mile and 10 miles, when defining visibility constraints for a layer in MapInfo Pro. The Map Uploader tool sets the layer visibility to that zoom range when uploading a map to the Spectrum repository.
To ensures that the layer visibility is converted from zoom to scale and the layer visibility is set to scale range (instead of zoom range):
- On the Map Uploader Preferences dialog, click the Maps tab.
- Select the Convert zoom constraints to scale checkbox.
- Click OK.
You will see this setting take effect the next time you upload a map.
