For a personal website I would like to plot coordinates of for example historic events etc. on an existing image.
This can be a photograph of an area of which I look up the coordinates of the 4 corners (put those in the database with the url of the image).
Based on the coordinate of the historic event I can select which photographs contain that coordinate and draw the event-coordinate on the selected picture.
This image should be created in php. What is the best solution to do this?
Sorry I'm a newbie in GIS, I only have this idea which I'd like to execute and so I came here.
