问题
I created a map with Google Map Maker. I did so by imported 5 different Excel files that had address fields and saved them all as different layers. The map now has about 500 addresses which are marked with pins that are color coded to the layer they belong with.
Is there anyway I can either use the "Draw Line" tool or another means to select a group of those markers/pins? Ideally I am envisioning being able to draw a shape around them and then being able to select those address to save them as a new data table or layer to export back to Excel.
Does anyone know of a way to achieve this? Even if it is another product then Google Maps? Thank you so much any help would be a life saver.
