Note: Your post will require moderator approval before it will be visible. (Spot elevations produced photogrammetrically are called mass points.) If you are lucky the jpg has a design and resolution which makes it easy to autotrace (with the right settings), but if it is to blurry or complex there is no way Illustrator will ever guess all the finer details from the chunky pixels. One tick mark is drawn on the triangle where a contour representing elevation 2400 intersects. -> SAVE AS DXF, During this process the contour lines cover the area to be designed so everything is OK.
