This PR contains two major new styling system improvements: Hover styles, and merged point styling. Merged point styling is an evolution of our previous
modestyle field. Instead ofhighlightornormal,modecan now be set tohoverorselection. The hover style is now also applied on the target feature, when a feature ID in the attribute panel is being hovered.By setting
point-merge-grid-cell, a tolerance may be defined which allows merging the visual representations of point features which share the same 3D spatial cell, map, layer, and style rule. This has two advantages:$mergeCount: In some map formats, it may be desirable to apply a style based on the number of merged points.This may be done to display a warning, or to check a matching requirement.
To this end, the
$mergeCountvariable is injected into each simfil evaluation context of a merged-point style rule.Check out the default style for an example.
You can simply test both features, by running the mapviewer with the default style and Island 6.
