Orthophotos provide one more layer of information to the stack. You can now include a high-res orthophoto in your dxf file under Contours. Aquiring and aligning orthophotos has been challenging before, but should now be trivial. Cetopo now provides you with accurate aerial imagery by the National Land Survey of Finland. Resolutions range from 16 to 1 pixels / square meter.
Orthophotos are now released as a BETA, meaning that the availability and quality of the data cannot be guaranteed. The underlying data is coming from a BETA service of the NLS. The Orthophotos will for now only be available as part of the Contours product, and only in the most common coordinate system, ETRS-TM35FIN.
To try out this feature, select an area, and then click Contours. Scroll down to the bottom of the settings, and enable Orthophoto. Click download, and you should receive a zip file with a dxf and the image.
Orthophotos will have some limitations during BETA.
Please try out this feature, and send us an email with your thoughts!
It's been a year since many of you registered, and it's now time to re-confirm your accounts. Unfortunately there was a bug in the re-confirmation process, Which should now be fixed. If there is still some problem in the process, please contact me here email@example.com
The UX of the map view has been improved as part of an ongoing process to improve the Cetopo work flow. Some features were unintuitive, and should now be more clear.
A significant improvement is the introduction of undo+redo. Selections can now be undone and redone using the familiar keyboard shortcuts Ctrl+Z and Ctrl+Y, or using the buttons on the interface.
Other notable improvements
Lasercutting small areas used to result in an unwanted "polygon" look due to the 2x2m resolution of the underlying data.
You can now specify a Smooth parameter for your laser cuts. This will tell Cetopo to smooth out the resulting contours for better aesthetics. The parameter is in millimeters, and specifies the maximum deflection of the curve. Lower values are thus smoother. If you prefer not to smooth the data, you can leave Smooth as 0.
Smoothing is an aesthetic preference. Sometimes a polygon look is preferable, or maybe you want something even softer looking than what smooth produces. Reduce allows you to reduce the amount of data points that are used. Reduce is also in millimeters, but specifies the minimum deflection of the curve. Higher values are more reduced. Leave Reduce as 0 for no reduction.
Reduce is applied before smooth. For example, Reduce = 5, Smooth = 0.01, will first reduce the curves to 5mm deflection, and then smooth them to 0.01mm deflection, resulting in a very smooth, but inaccurate result. Aggressively reducing the data might result in bad laser cuts, with layers that dont stack properly. Experiment with different values and use the 3D-preview to verify how it will look!
