M map won't run

I'm trying to run m map, I have downloaded this and made it part of the pathway on matlab, I then run this line:

m_proj('utm','lat',[29 19],'lon',[-82 -97])

then:

m_gshhs_i('patch',[0.5 0.5 0.5]);

but get given this error:

Warning: Coastline file private/gshhs_i.b not found \n(Have you
installed it? See the M_Map User's Guide for details)\n ---Using
default coastline instead 
> In mu_coast>get_coasts (line 460)
  In mu_coast (line 101)
  In m_gshhs (line 116)
  In m_gshhs_i (line 28) 

I have checked the file and everything is there and in the pathway, plus have redownloaded mutliple times, so if anyone has any ideas that would be a great hekp, thank you.

If you enter just load coastlines does the error still occur?

[Hollie Cushion]

when I type that in it says there is no file or direcctory

[Mark Brandon]

So coastlines.mat is part of the Matlab mapping toolbox so unless Hollie has that toolbox it won't be installed.

It's a path issue isn't it? Did you edit the m_gsggs.m script as described here Hollie

"If the database files are not in subdirectory m_map/private, you must edit the FILNAMEsetting in m_gshhs.m to point to the appropriate files."

https://www.eoas.ubc.ca/~rich/mapug.html#p8.6.1

You could try editing it to point to the absolute path rather than the relative path?

[Hollie Cushion]

okay thank you, that made the first line run but now its saying it can't find the gshhs_i.b in the folder thats been selected and it isn't in there, so do you know where I get this from?

[Hollie Cushion]

I've found it now, thanks for your help

[Minerva Tellez]

Can you tell me where did you find the gshhs_i.b, please? :(

I have the same problem, can you tell me how you solved it?

you can download a new coastline data and load in the path ， the original tool box do not include it

1. Visit the National Centers for Environmental Information (NCEI) website at "https://www.ngdc.noaa.gov/mgg/shorelines/data/gshhg/latest/" to access the GSHHG (Global Self-consistent, Hierarchical, High-resolution Geography) data files.
2. Locate and download the file named gshhg-bin-2.3.7.zip from the list of available files.
3. Once the download is complete, extract the contents of the ZIP file. Within the extracted folder, search for a file named gshhs_i.b.
4. Copy the gshhs_i.b file to the data folder located within the m_map folder in your project directory.

By following these instructions, you should have successfully integrated the GSHHG data into your project. This setup is crucial for the correct functioning of the mapping features. Good luck with your project, and should you encounter any issues, feel free to seek further assistance.

Hi

You can this :

"If the database files are not in subdirectory m_map/private, you must edit the FILNAMEsetting in m_gshhs.m to point to the appropriate files."

Thanks

That is what Mark suggested in 2019
