One of the strengths of OCAD is the generation of smoothed contour lines.
With the latest Service Update, a combined method of TPI and 3D smoothing is used for the calculation, which leads to improved results. The file size also shrinks, because at the same time irrelevant contour vertices are removed and the contours are converted into Bézier curves.
In our example, the not smoothed contours appear brown. The smoothed contours according to the new method (blue) are cleaner and show the terrain more precisely than according to the old smoothing method (green).
How contour lines can be generated is described in detail in our Wiki.
With the latest update we launched the OCAD Sketch Layer as a Beta version.
The new Sketch Layer and it’s tools are designed for orienteering map field work with a tablet computer and a pen.
Mapping with a tablet in the terrain has some compelling advantages like real-time GPS positioning and the possibility to switch between different background maps. However, the drawing and editing tools were not yet designed for use with a tablet and pen.
This was the trigger for this latest development: The OCAD Sketch Layer makes drawing on the tablet very ergonomic. Even more: Numerous colors and different line widths are available and with the eraser tool you can very easily delete parts of the sketch without having to select the features before.
We hope you started the new year well and healthy and have some interesting mapping projects ahead of you. There is no lack of mapping projects for our employee Andreas Kyburz. In this Video he shows you how he georeferences an old sprint map and renews its symbol set.
In the last OCAD Blog the different drawing modes were introduced. As you have probably already experienced, drawing objects requires practice and takes time. It becomes tedious if you have to draw an object apparently twice, for example a border line with a fill area.
Fortunately, you can duplicate objects so that you don’t have to draw them twice.
To only duplicate an object, you can use the Duplicate or Move and Duplicate function. Or simply select an object in the drawing window, press CTRL+C and CTRL+V.
Now let’s take the Fill or Make Border or Duplicate Identically function. As its name indicates and as you can see in the picture below, you can fill areas, make borders or duplicate object identically. Select e.g. a water area and add a border line with just one click.
Last but not least, there’s the Move Parallelfunction, with which you also have the possibility to duplicate objects by holding the CTRL+SHIFT keys.
In the example below we have only drawn the main street and added the labelling and the watercourse with the function Move Parallel. Besides the time saving, the absolutely parallel course of the objects should be mentioned.
To draw an object in OCAD, you need to select a drawing mode. Since the last Service Update, there is a tutorial file to familiarize beginners with the different drawing modes. But also advanced OCAD users will make one or the other discovery.
Therefore it is definitely worth a look!
The Drawing modes.ocd file can be opened in the folder OCAD menu File > Open Sample Maps.
