The map is read automatically: floors, stairwells, controls in course order, one-way arrows and the four-way crossing. You check the result on the next screen. Everyone using this server can then add their runs to it.
Open the race on lof.lv, choose Split, and save the page as PDF (Print → Save as PDF) or as a web page. Or copy the whole page (Ctrl+A, Ctrl+C) and paste it below.
Course order as read from the course lines. Click a row to find it; Move, then click the map to place it.
Stairwell letters per floor. Red flights go up from that floor, blue flights go down; the same letter on different floors is one stairwell.
One-way stretches (green arrows) and four-way crossings (straight on only).
Controls that can only be reached through one stair flight (inside a stairwell or fenced off by tape). The route finder normally sees these from the walls; add one here when it doesn't.
Reads the PDF from scratch (floors, letters, controls). Your manual fixes are replaced; imported results and saved runs are kept, and runs are worked out again.
