    Is the map a simple image that already exists?

  • @Tom: Most likely it is a screen shot of some map application, e.g. some .png or .jpg file.

  • If the map is an already existing file of .jpg, .pdf or .png format, use TikZ to overprint it with math content. If it is not existing, use Tikz as well ;-)

  • Yeah. I got it from academic paper

I will assume that you have the map as a picture (.jpg, .png, ...).

I am using the example image from the graphicx package. To illustrate the use.

You can use TikZ to draw on the image and add lines. I have added two points and a connecting line. The points are arbitrarily named (here p0 and p1). You can add many points and connect them with the a line (just add -- (p3) and so forth to the existing one).

% with ideas from https://stackoverflow.com/a/2628796

\documentclass[tikz]{standalone}
\usepackage{graphicx} % for example images

\begin{document}
    \begin{tikzpicture}[every label/.style={fill=white, inner sep=1mm}]

    % styles
    \tikzstyle{myLabel}=[draw=black, circle, fill=white]
    \tikzstyle{myLine}=[draw=blue,  double]

    \draw (0,0) node[inner sep=0] {\includegraphics[width=10cm]{example-image-a}};

    % nodes
    \node[myLabel,label={above:$(l,t)_2^D$}] (p0) at (1,2) {} ;
    \node[myLabel,label={right:$(l,t)_3^D$}] (p1) at (3,1) {} ;

    % lines
    \path[myLine] (p0) -- (p1) ;
    \end{tikzpicture}
\end{document}

this example will look like this:

With a picture of a "real" map (and a photo by Lorenzo Cafaro from Pexels) it will look like this:
