I’m making a simple http server and I want to add a world map

  • 0

I’m making a simple http server and I want to add a world map feature, that displays client geo location.

I got two questions:

  1. Is there a way to find out lat/lon of an IP address without using sites like ip2location.com?

  2. How can I geographically display a point on an image(world map) with giving lat,lon as an input parameter? is there a formula for that?

Thanks!

    Is there a way to find out lat/lon of an IP address without using sites like ip2location.com?

    No, unless you create and host your own database.

    How can I geographically display a point on an image(world map) with
    giving lat,lon as an input parameter? is there a formula for that?

    Both Google and Bing Maps provide such functionality. Here’s an example with Google Maps which allows you to place markers on a map given their latitude and longitude.

    UPDATE:

    You could use a Mercator Projection to place a point given latitude and longitude. You may take a look at the following article which explains the technique.
