I strongly feel we should have some default functions which resolve display/viewing issues for overlapping features. Two examples which I recently encountered involved the display of multiple map markers for the exact same lat/long point, another situation involved overlapping map markers which were completely unusable due to proximity grouping display issues, finally I have been loading parcel data into the system and often times these polygons overlap such as displaying one polygon for a subdivision APN along with multiple individual polygons within this subdivision polygon... In these cases data can overlap and is either not legible, visible or selectable. Suggestion on my end would be a simple and basic solution to toggle on/off the identification of such areas or in terms of clustered markers allow a simple way to define optional cluster proximity, optional label to display # of results in a cluster/cluster color. Look at Redfin.com and type in "San Diego" for an excellent example. Feedback/Thoughts?
