To use the OCAD Route Analyzer 2.0, course setters need a current map as well as a Digital Elevation Model (DEM).
This is loaded into the map or course setting file and ensures that the climbing and slope gradient are included in the route calculation. The DEM is typically created by the cartographer and has traditionally required a lot of memory.
The DEM can now be optimized and compressed without loss of quality for route calculation. This significantly reduces the file size of the DEM and makes it easier to share. The optimized elevation model can also be embedded directly into the map or course setting file, as is already possible with layout images.
On mobile devices, you can zoom in and out at will. Zooming in is appreciated by the map makers as it allows more precise drawing and sketching and more accurate display of the background map.
However, by zooming in and out, map makers are not working at a fixed scale and so the sense of distance within the map is lost. This was easier when mapping with pen and paper where the scale was fixed.
A few things can be done to improve the feeling for the scale on a mobile device:
Working with the OCAD Sketch App
Make use of the scale bar that has been added in the latest update of the app. The scale bar can be turned on or off in the settings.
Adjust the distance between the north lines. You can do so in the settings. E.g., set it to 1mm in a project with a 1:10’000. This gives you every 10 meters a line. In a 1:4’000 project, use 2.5mm to get a line every 10 meters.
Know the different line widths. It is advantageous to know the line widths and to sketch objects accordingly. E.g., an impassable wall on a sprint map with a line width of 0.4mm and contour lines with a line width of 0.21mm.
