I have a "geolocation on a custom non-Google map image" question that relates to several recent questions/discussions on stackoverflow.com, but involves a different issue I'm hoping to get a little concrete help with.

Unlike Dtnand in Get X,Y from LAT,LNG custom svg map and Phpdna in Convert latitude/longitude to pixel coordinate?. I already have the geolocation latitude/longitude coordinates from the user's cell phone translated into x,y coordinates on my custom, non-Google map image (courtesy of Trimaps custom JavaScript library).

What I need is a way to place a geolocation marker image (blue ball, red ball, whatever) on my custom, non-Google map at the x,y pixel coordinates calculated by Trimaps' JavaScript library. I'm a content guy, not a programmer, so I'm unsure where to turn on this.

Is there an existing JavaScript library that will accomplish what I want to do? The map is to be displayed on the Web. Thanks for your help...

Am I correct in understanding that you have the x and y coordinates of the pixel you want to place and the marker to be placed there? Are you looking for a canvas or svg solution?

You're not really looking for a mapping libaray here but a graphics solution and I would suggest either starting to research the HTML 5 canvas element (which I think would suffice in this case) or look to implement a more complex solution with a library such as d3.

Am now prototyping a solution using LeafletJS and some JavaScript from heyman on GitHub at https://github.com/heyman/leaflet-usermarker. Will report back soon...
