SODMAP will open in the “Temporary Places” panel on the left hand side of the Google Earth screen. If the “Places” panel is not visible it can be viewed by pulling down the “View” menu and selecting “Sidebar”. SOD positive and SOD negative results as well as individual years and collections may be expanded, collapsed, and checked on/off in the “Places” panel. The map legend may also be toggled on/off in the “Places” panel.
The details of individual collection records may be viewed by mousing over and clicking on them.
Zoom in to view points that are close together. Overlaid points will spiderfy when moused over.
