RMR 2022 - Maps!

24 May 2022 1:28 PM | Garry Spicer (Administrator)

The event maps are now available!

It is strongly recommended that radio operators use GPS based navigation on rally day.

The files provided below are intended to help with this part of your rally day. Keep in mind that cell coverage is poor in these areas, so be sure to download map tiles to your device prior to rally day.

These maps are in KML format. They are not image files! If you need them in GPX format (some GPS devices require this) or you would like them in a CSV to import into a spreadsheet, then I suggest using one of the online converter services available on the Internet. If you want image files, then I suggest making them with an appropriate application that can import KML format (Google Earth, Bing Maps...).

Contrary to rumour, there are no deliberate deceptions or hidden limitations in these files. While I am as subject to human error as anyone, I have taken steps to ensure that this information is as accurate as possible. I even scan my computer with a reputable anti-malware program to reduce the chances of spreading computer viruses. However, the utility that you obtain from these files will be closely associated with the software that you use to read and display the GPS data within them. I generally use APRSIS32 or YAAC. Some people report success with a program called Gaia. In any case, be sure that you understand your GIS software, its features, and its requirements.

First is a KML with just the field operator locations (blockers and control points).

Second is a KML with the routes (roads), places of significance, and waypoints. These items are marked to help you navigate to, from, and around the venue.

It is possible for changes to occur between now and the rally, so keep watch in this blog for possible updates.

    I was reminded of a configuration recommendation regarding GPS units.

    A GPS device / GIS software package with the event kml files loaded can be very helpful. However, it is strongly recommended that audible direction / navigation instructions be shut off. Very few GPS devices have a good understanding of the course roads Most units will give you misleading - or even dangerous - navigation recommendations. You are far better off to navigate on your own using the electronic GPS map with the items from the kml file overlaid.
