Topographical Map 2D Image to 3D data for model

Hello All,
I am trying to figure out a good way about creating data for a 3D model (STL) from an image of a topographical map.
In particular, if you look at the image I've attached, I am trying to figure out how to create data points representing the boundary of the lake, along with the altitude contours within the lake image. The data (spatial coordinates) I would then figure out how to somehow convert to an STL.
Anyone have good ideas on a starting point?![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/784403/image.png)

The data used to create that must already exist somewhere. See if it is possible to find it onlline. (I have no idea where to begin with that, however GPS providers could be an initial source, directing to a government source.)
