I have a netcdf file
vardata=ncread('TL__Map1_15C_sand1__20mres_-36.265137N_174.790466','TLdata');
ncdisp('TL__Map1_15C_sand1__20mres_-36.265137N_174.790466')
Source:
X:\Matlab Scripts\TL__Map1_15C_sand1__20mres_-36.265137N_174.790466
Format:
netcdf4
Global Attributes:
description = 'TL data set TLmaps/TL__Map1_15C_sand1__20mres_-36.265137N_174.790466'
history = 'Created Fri Nov 12 09:55:31 2021'
source = 'netCDF4 python module tutorial'
Dimensions:
ilat = 280
ilon = 489
ifreq = 91
Variables:
TLdata
Size: 91x489x280
Dimensions: ifreq,ilon,ilat
Datatype: single
Attributes:
least_significant_digit = 2
units = 'dB'
H_latdata
Size: 280x1
Dimensions: ilat
Datatype: single
Attributes:
units = 'degN or m'
H_londata

I know that the projection is WGS 1984 Mercator 41 and the lat/lon coordinates are in UTM.
I would like to be able to convert this grid to lat/lon, can anyone help?

I have since realised that it is not logical to modify the spatial data in this way as it would break the regularity.

Hey Louise,
If you wish to convert the UTM to lat-lon cordinates I would suggest looking into UTM2LL.

My latitude array is 280, and the longitude array is 489. It appears you cannot convert these using utm2ll or utm2deg. I have answered this question as I understand now that it's not appropriate to convert the array in the first place.
