Generating contours and cliffs with OL Laser

I used OL Laser to generate files containing contour and cliff data. I prefer the way OL Laser handles cliff data, compared to Karttapullautin.

Run OL Laser, then:

• Open your LiDAR data file (it can take a little while). Use the ‘open laserfile’ button.
• Let OL Laser to some preparation by pressing the ‘Create GRD/TIN’ button
• Under ‘O-Map objects’ select ‘Contours’ and then ‘Create objects’. The process is fast, but you won’t see the results until the next step
• Under ‘Draw’ select the contours.
• You can save the contours as an OCAD data file
• Here’s how it looked for me:

• The process is virtually the same for cliffs. Just select that option under ‘O-Map objects’.

• You can create new parameter sets with your preferences. Use the ‘Maintenance’ menu item. Then use the ‘New’ button.
