mc2bsbh - MapCal Template to BSB Template Conversion

[sinbad7]

Marco...

Here's my pennies worth of the accumulating Chartcal.Dir file.
I now re-name the file like 'NorthAtlantic-CHARTCAL.DIR' and store them in a special directory for future reference,having first deleted any un-wanted data. The file upload is not working tonight it seems so here is the listing:

Can you (or anyone) confirm that there will always be a space in the first position of all continuation lines?

As for the multiples, I am considering this possibility:

A switch -b for batch. -b extension

If run in batch mode, it will look for [nz1404.png] file in the header, then create a file of nz1404.extension

It will just loop through and create multiples.

Now that I have said that, we'll see if I can do it.

What do you think?

Dan,
I think your suggestion with a -b switch make sense. That makes it possible to go through and create calibrations for a bunch of files and then create tif2bsb templates in batch, or if the user prefers ultimate control, to create them one at a time.

I suggest that if there is more then one set of calibration data in the chartcal.dir file and the user does not use the -b switch, that there is an error message in this approximate style:
"Error: Multiple errors in the chartcal.dir file. Please use the -b switch or erase all but one entry in the chartcal.dir file."

I dont know for a fact that multiple lines start with a blank, but it certainly seems so. I think it seems fairly safe to assume this is the case, at least for the CR parameter.

My thinking, also. I'll see how hard it is to implement.

And the CR part will be pretty easy.

Thanks,

I need to re-adjust a previously calibrated name.kap file.
MapCal can read name.bsb files but will not accept our conversions.
Is there any other way to re-adjust calibrations than doing it all over again?
Basically I just want to adjust the frame corner geo locs.

[sinbad7]

Marco/Dan...

I re-calibrated my Pacific.tif map,using only the scaled corners to obtain the geo locs and also the x,y, parameters from the same corners. The resulting Pacific.kap map shows the red map outline perfectly EXCEPT at the top where the frame is well outside the scaled frame. Any ideas why? Consequently my AIS target locations are not showing the correct geo loc in OpenCPN. I have reverted to the old Pacific.kap file based on 6 sequentially selected geo locs on the map,plus the 4 corner locs as it gives a much more accurate if not EXACT locations of my AIS targets. I am comparing the geo locs between the AIS query boxes and the OpenCPN locations. The scale of this chart is 1:10 mill

Hi

I checked that maps created with mc2bsbh do not load in MapCal nor in polarview. The simple modification to make them loadable is to add the row in the header specifing the bsb version. So just add the following line

VER/2.0

This line should be the first after the copyright. The header should look like as:

! Created by mc2bsbh-0.00.01 - Use at your own risk!
! 
VER/2.0
BSB/NA=North Pacific Ocean - Southeastern Part
......

Ciao, Marco.

Ciao, Marco.

I'll do that this evening. Don't have time to work on the batch version right now, but I can do quick stuff like this.

[sinbad7]

Marco..

Tried your solution,BUT,look at the result in MapCal. Attached the header details.

It looks as you have modified something in the .kap map with a text editor. Try bsbfix.exe (in libbsb)

Ciao, Marco.

[dacust]

• VER/2.0 added.
• Multi-line CR entries now handled as multi-line comments. Sorry, but the lines may not break the same place as the original.

Code and .exe uploaded.

I don't think there is anything outstanding except for the batch processing enhancement. Have I missed anything?

When trying to compile on linux I get the following error:

   $ g++ mc2bsbh.cpp -o mc2bsbh
mc2bsbh.cpp: In function 'int main(int, char**)':                                                    
mc2bsbh.cpp:294: error: 'strtod' was not declared in this scope
mc2bsbh.cpp:320: error: 'strtod' was not declared in this scope

To take care of this I added this:

#include <cstdlib>

after the other "includes".

With these changes made and using -Wall, always a good idea:

g++ -Wall mc2bsbh.cpp -o mc2bsbhmc2bsbh.cpp:
In function 'int main(int, char**)':
mc2bsbh.cpp:20: warning: unused variable 'incoming_work'
mc2bsbh.cpp:32: warning: unused variable 'argcount'

The line

using std::string;

can be deleted. You have already declared that you are

using namespace std;

Can't you wrap up the code repeat at the end, in a function?

I hope this helps!

Looking forward to test your utility.

Thomas

Cagney,

Thanks for the help.

I have yet to figure out how to do functions. I could use them a lot. It'll probably be one of the next techniques I try.

I'll do start on that and do some cleanup this weekend.

Marco ..Dan..

Think you have forgotten to include the DEPTH feature,i.e. feet,fathoms or meters...

[jonasaberg]

Sinbad,

I checked and in MapCalII "Edit->Chart Information" the "Depth Unit" parameter sets a parameter "DU" in the chartcal.dir file.
DU=0 for unknown
DU=1, for meter, 2 for feet and 3 for fathoms.

This is correctly translated to the "UN" parameter by the mc2bsbh.exe converter when I try.

Did this not work for you?

Regards
Jonas
