2020 Zaxxon method

Hello, I'm creating a guides set (in spanish) to use the zaxxon methos in 2020 using AGR data for any location in the word.
In my guide I use opentopography data to create the AGR elevation files and use them to run the Zaxxon method.

https://balamacab.medium.com/

I hope helps the people that still use this method of generating tracks and circuits for rFactor or RBR; the guides are quite long, I do not know if i'll translate them to english.

Mate, as I was just about to give up.. Read your post and started all over again. Thanks so much for this.

This looks promising, tried my luck with the agr data, even though I got stuck at the s3 road section of getting the elevation data. It is either because:

1) I made the route kml as directions from start to finish of the route and not by clicking points by hand at the middle of the road.

2) My subdivision of the agr file got stuck at 97,9% for some reason.

Dont know what happened, but I will try again.

Thanks!

Also regarding the firspoint, the route that google calculate is not acurate, try to create the route by hand trying to put your point in the middle of the road, you'll end up with a smooth road.

Thanks for the help.

I'm stuck though again at the same point.
1) I made the track by hand

2) Could my AGR data be too small to subdivide? the size of the output_srtm file is 2.065KB
Also, I had to use a previous version of SAGA, so my 32bit win7 system could run.

Here is a picture.
Operation fails when I try to press "create elevation profile".
I don't know man, any help would be much appreciated.

Ok, did you did the geoconversion of the coordinate system? the octave console is saying the it doesn't find elevation data.
Please share your DEM file.

ok.. I try and do the process for your file... aparantly the message
ERROR: Those AGR files do not contain useful elevation data
is waiting an "enter", after it I coud continue an see the road profile...

Give it a try, also I generated a bigger AGR zone and the message shows; i'll send the generated an corrected AGR to your mail.
Give it a try

This is an awesome guide, thanks!

I had worked with the Zaxxon method a lot a few years ago using Google Earth, not AGR.
After seeing your post I thought I might re-work some of my older rally stages.

I too am getting stuck at the same stage as Thanos_V "AGR files do not contain usefull elevation data"
I also tried making the AGR a lot bigger with no success, how much bigger than the stage/track does it need to be?

I was a little unsure if I had selected the correct UTM zone (NZG2000 / UTM zone 1S - New Zealand)?
My rally stage is: https://www.google.com/maps/place/I...be28d80977205!8m2!3d-36.6693467!4d174.4822461

Your thoughts would be appreciated.

Cheers,
AJ

Select the area near the road...

Download DEM file...

Import geoTiff to SAGA GIS....

Reproject to UTM (new!) using .... Geoprocessing --> Projection --> UTM Projection --> UTM Projection (Grid)

Define source grid system, resampling, preserve data type, and define a Cell size if you wish to interpolate the default 32m resolution to a smaller one, also check if your location is in the south hemisphere (critical)

This georpocess reproyect to UTM without having to search for the zone manually.

Delete the original map from SAGA and leave the converted...

Export to text file....

Split the file in to segments using octave and zaxxon

>addpath('c:\project\father\scripts')
>cd c:\project\agr
>split_agr('help',5)

1612989704647.png


Create a KML with the road...

1612988533432.png


Copy the kml to the path in the guide and run zaxxon...

1612990034474.png


from here on the process works.

Try to do the geoconversion using the geoprocess UTM Projection (Grid), it works. if you have problems write me.

Thanks so much, Reproject to UTM worked first time :)
The Zaxxon method has a steep learning curve for the average user, however I do find your guide easier to follow this time around, and the AGR version is a lot quicker overall as well.

Thanks again, I will post an update of the new (and improved) stages in due course ;)

Hello, I have a error in s7_wall. What can it be due to? I think I hadn't errors in other sections.
