The Strengths of WMS and WMTS

The terms WMS and WMTS may sound scary to people who are not very familiar with computers. But no worries: It’s pretty easy to use them and knowing their strengths is of great advantage for mapping and even for course setting.

So, what exactly is WMS and WMTS?

WMS (Web Map Service) and WMTS (Web Map Tile Service) are interfaces for retrieving geodata as raster data over the internet. More and more of these services are available today.

  • A WMS is calculated on the server side and delivers one image per request.
  • A WMTS delivers tiles that have been pre-renderd on the server side, and cached on the client side. This will reduce waiting time for the data and bandwith.

In OCAD, you can load WMS/WMTS as a background map. To do so, choose the WMS / WMTS command from the Background Map menu.

Typical layers are e.g. official cadastral surveys, topographic maps, aerial images, but also protected areas or forest reserves. All these data can contain useful information for your map project.

Therefore, you can easily update maps or add additional information to it with WMS/WMTS. In the example below, we connected a WMS from swisstopo and displayed a layer to show Forest Reserve Areas on a map.

Also, you can set courses on a WMS / WMTS layer. A step-by-step guide can be found in our OCAD Wiki.

Review of OCAD Development in 2021

Let’s take a look back at the three most important developments of the past year. Did you get them all?

#01: Sketch Layer

The Sketch Layer and it’s tools are designed for orienteering map field work with a tablet computer and a pen. The main approach is to make field work drawing as ergonomic as possible.

Learn more about it in our Video on YouTube and in the OCAD Wiki and and give it a try!

#02: Fill Bounded Area mode

Thanks to the Fill Bounded Area mode you can draw your map even more efficiently. This function fills empty areas that are bounded by various objects from line or area symbols.

#03: Improved Live Preview

The Live Preview of objects makes their dimension visible already during drawing. Live preview is no longer limited to line objects, but is now also available for point objects.

In addition, a so-called Legibility Halo can be displayed for point objects. The distance of this legibility halo is based on the IOF specifications for orienteering maps and supports the cartographer to draw objects with enough distance to each other.

These were the biggest milestones last year, but stay tuned: We have great innovations in the pipeline this year as well!

Win an OCAD License!

Take a chance and with a little luck get an OCAD license!

OCAD is sponsor of the following two contests:

Course of the Year by worldofo.com

There will be a voting process among the readers of the popular website
World of O in order to name The course of the year 2021 in each
category (Sprint, Middle and Long).

OCAD is one of the sponsors of this inspiring survey and you have the
chance to win a 3-Year OCAD Orienteering license.

There will be a prize for the first one suggesting the course which ends
up becoming The course of the Year 2021, and prizes drawn among the
ones suggesting and voting.

More information here.

Course Setting Contest by Swiss Orienteering

In the second contest there is even more to win: a 3-year license each
of OCAD Orienteering, OCAD Starter and OCAD Course Setting!

This time you have to set your own courses in the course setting contest
of the Swiss Orienteering Magazine. The task is to convince the jury
with a performance-oriented D20 and H75 long distance course.

More information here in Deutsch, French or Italiano.

Good luck!

How to reduce the file size?

Have you ever wondered why the file size of one of your map is so large? Then it’s probably time to clean up your map.

Here are some suggestions how you can reduce the file size:

#01: Optimize/Repair

Choose the Optimize/Repair command in the Map menu to optimize (reduce) the size of the map file and repair damaged objects. With edit operations such as deleting objects, empty space is created in the map file. This function removes this empty space and therefore reduces the size of the map file. It’s therefore highly recommended to run the Optimize/Repair from time to time.

#02: Select and delete unnecessary objects

In the picture example above, you can see that there are many objects without symbols, unknown symbol or invalid symbol type.

Choose Select Objects by Symbol in the Select menu to select all objects with certain symbols or in a certain layer.

You can now assign the selected objects to new symbols or (what is probably more often the case) delete the objects.

Select By Symbol.

#03: Smooth not smoothed contours

When creating contours with the DEM Import Wizard, you can choose to create not smoothed contours. These contours consists of many vertices and let your file size increase.

Select the contours and run the Smooth command in the Topology menu to reduce the amount of vertices. Make sure to choose the tolerance so that no information is lost. Run the Optimize / Repair command afterwards.

PS: To select all contours at once, either right-click on the contour symbol in the symbol box and choose Select Objects by Symbol or use the Select Objects by Symbol function.

Select contours and run the smooth command.

#04: Remove unnecessary areas

If you import existing geodata, e.g. by using the New Map Wizard, you probably import an area too large. You can Crop the map to the size of your actual project scope and remove unnecessary areas. Run the Optimize / Repair command afterwards.

Crop part of your map that you do not use.

OCAD runs on Windows 11

Microsoft has recently released a new update with Windows 11, which can be installed on newer computers.

We have tested OCAD on Windows 11 and have not encountered any problems or received any reports from other users.

OCAD can be used as usual on Windows 11. Only the dialogs appear in a slightly different style.
