first of all let me make a disclaimer that I am completely new to the whole programming. I have done a little bit of HTML in the past and that’s about it.
Now, what I want to create is a map (ideally offline) into which I can import a large number of street addresses as points of interests. So far so good. Finally, once I have imported all those addresses, I want to be able to click anywhere in the map (or enter an address) and have all previously imported POIs which are within a specified radius around where I clicked read out and exported into a list (e.g. a csv file).
As I am not sure if I have described what I mean very well, I will explain the end result I have in mind one more time. I imagine a tool similar to Google Maps (preferrably offline, but that’s not super important). Into this map I will have imported a bunch (I am thinking a few thousand) of addresses, spread out accross the entire country. I then want to be able to specify one point on this map plus a radius of, say, 20 miles, and have the tool generate a list of all addresses (which I have imported previously) within 20 miles of the point I specified.
A few issues I have are, how can I “conveniently” import thousands of addresses from an Excel file into an open-source map. I am fine with copy and paste but I can’t look up the GPS coordinates for each individual address. So the open-source map I use would have to “know” what point on the map the street addresses are referring to.
Secondly, I know there are websites that let me draw a circle of a specified radius around any given point on a map. So I presume this part won’t be too difficult. But I have no idea what I can to about the next step of having those addresses exported into a list.
Any pointers and advice as to what tools or code I could use will be greatly appreciated.
Thank you very much!
