Troubleshooting

This section describes various general problems that occur with Rover and how to address them.

Shapes drift or detach as you zoom in

TODO: example screenshot

This is generally a problem with LOD and zoom configuration. The shapes can only be represented as precisely as the tile’s granularity; zooming in so that the display scale is smaller than that will cause this effect.

First, read about and understand tiles, tile coordinates, LOD, and granularity.

Check the log for granularity values; they are listed early in the publishing process.

These things affect the granularity:

• zoom levels (aka elevator buttons)
• legend scale regions
• number of LODs
• manual LOD and granularity configuration
