> What is a rangeRing ? The map is for Search & Rescue use. For SAR, we break the US into "grids" based on lat/long and "sectional" aviation charts. There are two labeling systems for grids. This app displays the grid lines and the grid cell labels plus provides a cross-hair mouse pointer and a lat/long readout follower. In addition the user can ask for a range ring, which is a circle whose diameter in nautical miles depends on the zoom level. The range ring does two things. Most importantly, it appears when the map is printed -- which the mouse cursor does not. Second, it gives the user a bit of map scale on the printed map. For example, if I am tasking an air crew to take a series of photographs I can give them lat/long and a printed map for each one and it is easy for them to correlate the printed maps to the appropriate aviation chart, even in the usual case where the target does not appear on the chart. > i.e. we do not know what your > circle is made of, due to insufficient context in code snippets.

The circle is created in the function ringStatusChange. It's just a simple new google.maps.Circle. The only thing done to it in the mousemove event is rangeRing.setCenter(mousePosition). It's not clickable. TIA -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group. To post to this group, send email to [email protected].
