# Bug Report
## Problem
When using navigator.camera.getPicture function with data url destination
type, the returned base64 string does not contain the gps exif information. I
am able to extract other exif data, like orientation or height, but the
longitude, latitude values are undefined.
### What is expected to happen?
For example, attaching an image from photo library with gps information, the
longitude, latitude values can be extracted from the base64 data url of the
image.
### What does actually happen?
Longitude and latitude values are given back as undefined.
## Information
I am using the base64 string of the image as destination type, because it is
necessary later on. So I can only use other destination types, if I can get the
base64 string of the image as well.
### Command or Code
```
var successCallback = function (imageData) {
var image = new Image();
image.onload = function () {
EXIF.getData(image, function () {
var lat = EXIF.getTag(this, "GPSLatitude"),
long = EXIF.getTag(this, "GPSLongitude");
console.log("lat and long: " + lat + " " + long); //and do
other stuff with the long, lat values
});
};
image.src = imageData;
var dataUri = "data:image/jpeg;base64," + imageData,
fileInfo = {
name: 'img.jpg',
type: 'image/jpg'
};
me.SaveImageData(dataUri, fileInfo); //display, put in local store,
send to server
};
navigator.camera.getPicture(successCallback,
failureCallback,
{
sourceType: fromvalue, //user selection
destinationType: Camera.DestinationType.DATA_URL,
targetWidth: 800,
targetHeight: 600
});
```
### Environment, Platform, Device
Android and iOS (tried on different versions as well)
capturing image and attaching existing one, both cases
### Version information
cordova 7.0.1
cordova-plugin-camera 4.0.3 (latest supported version for this cordova
version)
## Checklist
- [x] I searched for existing GitHub issues
- [x] I updated all Cordova tooling to most recent version
- [x] I included all the necessary information above
Note, I could not find any information that this plugin is not able to
return the gps information in the exif data, that is why I consider this as a
bug. However, since I am no expert in cordova, maybe I am doing something wrong
or missing something. Therefore I posted a question to
[stakoverflow](https://stackoverflow.com/questions/62781535/in-cordova-navigator-camera-getpicture-function-data-url-does-not-return-gps-lo)
as well. If this does not qualify as a bug, but somebody can help, I would
appreciate anything.
