Is there a way to draw more than one radius circle at a time from two different locations?

I would like to have 3-4 different 50 mile radius circles on the same map at the same time.

Assuming this is possible, is there a way to designate a primary location? Let's say I have two home locations within 75 miles of each other with a few dozen secondary locations around them.
With the first question I would like to draw a 50 mile radius from each home location. Since they are so close together, some of the secondary locations will overlap and be within 50 miles of both home locations. I would like to pick a primary so any overlapping will only show up in the list / count for the primary

Hope this makes sense.

Thanks!

Take a look at this utility -

Would you manually be picking the primary locations?

I would prefer to pre-set the primary locations, not the end of the world if that's not possible.

If this all works out, my final map may have a few thousand secondary locations with a couple hundred primary.

I downloaded the above file - very cool. When I create a manual circle with the "Find Nearby Places" button, it says how many locations are within the circle. Is there a way to do the same with the above script?
Ultimately I need to know how many secondary locations are in each circle without manually counting them. This is where the example of having two primary locations close together comes in. I would like some way to specify for a primary location to omit any secondary locations that are within the boundary line of another primary.

Sorry I'm not fully understanding what you want to do. Do only the primary locations have the circles?

Yes I think, programmatically you can do a FindNearBy Places and loop through the results. Should not be too hard.

How do you decide which primary location gets assigned the secondary location if the secondary location is within the radius for two primary locations?

Correct, only the primary locations will have circles.

It's going to be a manual addition to the map I'm sure. I know which locations need to take precedence, just need to find a way to show this on the map.

The ultimate goal will be clicking on a primary location and having the information window pop up showing how many secondary locations are within the circle.

So far I think I'm on the right track. I was using GoogleMaps for this, the number of locations was really taxing the web browser when loading. It looks like MapPoint is better suited for this amount of data.

Do you need some custom coding? I am trying to envision the workflow.. I think you could fairly easily have another column in the Excel spreadsheet that writes out how many secondary locations were within the circles for the primary locations - however like you say there would be overlap. Maybe for each row it goes down, it deletes the secondary locations it has already found? However, then it would just sort of be arbitrary which primary location the secondary location is assigned to...

At this point I'm open to suggestions since I'm very new to MapPoint I'm not sure what is capable right out of the box or what will require extra coding.

Thanks for the help.

How far have you gotten?

If you use that radius drawing tool to draw circles for your primary locations, and then import all your secondary locations, you can right click on any of the circles and select Export to Excel to get a complete list of all the pushpins within that circle...

For "overlap" (secondary locations that appear in two or more sets) I think you would have to weed them out afterward in a database.

I haven't been able to spend much time on this, the initial radius tool helped out a lot to get things rolling.

I'll try the excel output, was not aware of that, might be a relatively simple way to do this.

Let us know how it goes.

For hundreds of radii or Primary locations, it would be nice to automate it, I'm just not sure how you will handle the overlap.
