Calibration of a map for Dummies
Calibration of a map for Dummies
Hello,
I'm working on a new scenery. After some problems for calibration, i found this old very nice post : http://forum.condorsoaring.com/viewtopi ... 1&start=15
Then I try to make the things easier. I create a program with excel to do everything you need for calibration.
It use the HDR files produce by 3DEM with UTM coordinates and create the CalibrationFile nedd by Landscape Editor.
If you have any question or detect bug, leave a message.
CALIBRATION TOOL USER MANUAL
- Open the "Calibration Tools - Condor Soaring.xls" wth excel
- allow execution of macros (important)
- Clic on the "1 : Select HDR file" button and select the HDR file created by 3DEM
- Clic on the "2 : Generate Calibration File" and save the "CalibrationPoints.csv" file in the condor/landscape/map/working directory. You should overwrite the existing file.
- Open the Landscape Editor
- Selection your map.
- Select "Calibration Points". You should see all the yellow mark of the calibrations points
- Clic on the "Calibrate" button
That's all.
Tips :
- There will be one calibration point for each corner of terragen tiles
- There will be a map of your terragen tile on the second tab of the excel document.
Edit : V1.1 to correct the mapping tiles : http://forum.condorsoaring.com/viewtopi ... =3&t=10934

Re: Calibration of a map for Dummies
Is this the technique which gives 100% accuracy?

Re: Calibration of a map for Dummies
With this method, the only error is in the UTM -> lat/lon conversion.
The verification to do : when the map covers 2 different UTM Zone
I update the file in the first post with a missing HTML link

Re: Calibration of a map for Dummies
Certainly looks accurate to me, nice job Lurik!
Re: Calibration of a map for Dummies
I made a test with a map which is on 2 UTM Zone. The Calibration File is OK.Lurik wrote:...

...
Even if you crop the map during the raw -> TRN convertion the file will be OK.

Thank you very much Lurik!
Very important add-on for all scenery creators!

Hello,
This is the new version of the Calibration Tool.
The Calibration File was good, but there was an error in the mapping of the tiles (the order of the tiles was wrong).
This new version have a correct Mapping Tiles

Re: Calibration of a map for Dummies
The future version of this tool can be found on the "new tutorial subject" : http://forum.condorsoaring.com/viewtopi ... =3&t=10934
This process to calibrate is still available.
The new version will have more feature.

Re: Calibration of a map for Dummies
Heeeeeeeeeeeeeeeelp!!!
i have tried everything... (at least everything I know...) and it still doesn't work
I have done it in Open Office but the resulting figures are wrong... The rows and collums ARE multiples of 64 so that is not the problem.
The *.hdr file: 35N
left_map_x = 168480
lower_map_y = 4994910
right_map_x = 398790
upper_map_y = 5202180
number_of_rows = 2304
number_of_columns = 2560
and the resultig figures are
0,0,0.000.000.000.045,0.000.000.000.026
230400,0,0.000.000.000.045,22.79
230400,207360,46.89,0.000.000.000.023
0,207360,0.000.000.000.047,0.000.000.000.026
Landscape editor will not open the scenery with this data in the *.csv file
so pleeeeeeeeeeeeeeeeeease help
regards

Re: Calibration of a map for Dummies
with the last version of the tool (2.7 light) i have theses result for your calibration :
excel :

0,207360,46.9658259172,25.6701689711
excel have more digit for 2 points, but the result are the same
Where are you? Which is your decimal separator?

Re: Calibration of a map for Dummies
Hi!
Merci pour les numéros
I live in Germany decimal separator is , (comma) We've figured this out (very late) last night
But thanks for your quick reply, I reaaaaly appreciate this The figures We've commed up with
are the same (OpenOffice2.0)
Thanx once again
Filip

Re: Calibration of a map for Dummies
I have one small wish if you can , and wish to help me.
I need the corners of each tile in utm units.
I manage to look in your excel and saw that you work with utm units and convert at the end so it should not be dificult to modify ...
Thanks in advance!

Re: Calibration of a map for Dummies
If you want the utm coordinate, you have just to add/substract 90*256 = 23040 from 1 corner coordinate to find the next corner.
Start with the right_x and botoom_y for the right south corner.

Re: Calibration of a map for Dummies
Made a few test and mainly it's ok but i have some issues:
- My scenery header data (cut with condor 3dem):
left_map_x = 152190
lower_map_y = 4876740
right_map_x = 612900
upper_map_y = 5429610
number_of_rows = 6144
number_of_columns = 5120
width in meters:
by columns: 5120 * 90 = 460800
by difference: 612900 - 152190 = 460710
So after your calculations i'm 90m less in one tile
Please tell me where i am wrong.
