Geotagging my coordinates with images

Hi,there . The code that i want to write is :(i have a file of images and each images has a gps coordination in my csv excel file , well i need a code that gets a coordinates from my excel and tags it to it’s own picture… and at the end when i get the properties of my pictures i can see the coordinates in details) … i wrote to many codes but I wasn’t successful …plz help me to solve it ..thank you . And i took an example of my code .

Picfile=(“address”);coordsfile=(“address.csv”);
for i = 1:height(coords)
    filename = coords.Filename{i};
    lat = coords.Latitude(i);
    lon = coords.Longitude(i);
    
    command = sprintf( lat, lon, filename);
    system(['exiftool ' command]);
end

height(coords) tends to imply that coords is a non-scalar struct. However, coords.Filename{i} is invalid indexing if coords is a non-scalar struct. I suggest using numel(coords.Filename) instead of height(coords)

Thanks can you help me more plz.i have problem in creating exiftool command to set gps location ….can you please explain what should i put or not in there !?

This part of my code is :

Cmd=sprintf(‘exiftool -gpslatitude=lat -gpslongitude=lon filename’);
Status = system(cmd)

And i get this error

Warning:error converting value for gps:gpslatitude(valueconvinv

)

And my full code is :

Clc
Clear all
Coord(“path of coords.csv”)
Photo=(“path of my image file”)
Coords=readtable(coord)
For i=1:numel(coords.filename)
Filename= coords.filename(i)
Lat= coords.latitude(i)
Lon= coords.longitude(i)
Cmd=sprintf(‘exiftool -gpslatitude=lat -gpslongitude=lon filename’);
Addpath(genpath(“path of my run_exiftool file that I downloaded from here”)
Status = system(cmd)

Thanks for your help in advance

MATLAB is case sensitive, so For will not be recognized as being a for loop.

Also, the quotes ‘ and “ are unicode U+2018 and U+201C which are not recognized by MATLAB. You need to use U+0027 and U+0022 instead.

Cmd=sprintf('exiftool -gpslatitude=%g -gpslongitude=%g filename', Lat, Lon);

Hi Moa,

You can use the ‘Exiftool’ open-source software to modify the EXIF Data of an image.

Refer to the following example code snippet to modify the GPS property:

imagePath = 'image_file_name.png';
latitude = 38.7041;
longitude = 77.1025;

% Creating exiftool command to set GPS location
cmd = sprintf('exiftool -GPSLatitude=%f -GPSLatitudeRef=%s -GPSLongitude=%f -GPSLongitudeRef=%s "%s"', ...
    latitude, latRef, longitude, lonRef, imagePath);

% Executing the exiftool command
status = system(cmd);

I hope this helps you!
