&nbsp;

A new firmware update for DJI Mavic 2 was released on 2018.10.11 ([v01.00.01.00](https://dl.djicdn.com/downloads/Mavic_2/20181011/Mavic_2_Pro_Zoom_Release_Notes_en.pdf)) and the latest status regarding the geotags is the following:

- **GPS Altitude&nbsp;** written in the EXIF file of the images **&nbsp;is correct.&nbsp;**  
Exif.GPSInfo.GPSAltitudeRef&nbsp; &nbsp;Above sea level  
Exif.GPSInfo.GPSAltitude&nbsp; &nbsp; &nbsp; &nbsp; 376.6 m
- **Latitude and Longitude** &nbsp;written in the EXIF file of the images&nbsp; **are not&nbsp;correct.**  
Exif.GPSInfo.GPSLatitude&nbsp; &nbsp; &nbsp; &nbsp;46deg 30’&nbsp; **-** 24.216"  
Exif.GPSInfo.GPSLongitude&nbsp; &nbsp; &nbsp; 6deg 32’&nbsp; **-** 17.914"

&nbsp;

At the moment, I would recommend&nbsp; **updating the firmware** &nbsp;version of the DJI Mavic 2 Pro and apply one of these three workarounds:

**1.- For those who use Pix4Dcapture for image acquisition.**

- Performing the mission with&nbsp;**[Pix4Dcapture](https://www.pix4d.com/product/pix4dcapture/)&nbsp;(iOS)**&nbsp;flight planning app produces a project file ( **.p4d** ) when downloading the images to the device, also called&nbsp;[Synchronization](https://support.pix4d.com/hc/en-us/articles/204057579#label1).&nbsp;

After successful synchronization, the .p4d file and images can be&nbsp;[extracted from the mission folder](http://support.pix4d.com/hc/en-us/articles/214516203#label2)&nbsp;when connecting the mobile device to a computer or by directly&nbsp;[uploading the project on the cloud](https://support.pix4d.com/hc/en-us/articles/204057579#label2).&nbsp;

This project file (.p4d) includes&nbsp;correct coordinates of the images and will position the images correctly in the project. For precise georeferencing, I recommend using&nbsp;[GCPs](https://support.pix4d.com/hc/en-us/articles/202558699-Using-GCPs).&nbsp;

**2.- For those who do not use Pix4Dcapture.**

**&nbsp;- 2.a Pix4Dmapper 4.4.9**

A new&nbsp;[Pix4Dmapper preview version](https://support.pix4d.com/hc/en-us/articles/115005738363-Pix4D-Desktop-preview-and-technical-release-notes)&nbsp;has been released (on January 24th, 2019)&nbsp; which reads the image geolocation from the XMP tags instead of the EXIF tags.&nbsp; **This only applies&nbsp;for&nbsp; DJI drones** &nbsp;(Including Mavic 2), for all other drones, the image geolocation will still be taken from the EXIF tags.

In case of DJI drones, the exact tags which are taken are:

- Xmp.drone-dji.Latitude

- Xmp.drone-dji.Longitude

- Xmp.drone-dji.AbsoluteAltitude

More information about EXIF and XMP tags can be found here:&nbsp;[EXIF and XMP tag information read by Pix4D](https://support.pix4d.com/hc/en-us/articles/205732309-EXIF-and-XMP-tag-information-read-by-Pix4D-Desktop)

Please note that the altitude can still be inaccurate. From our experience, the correct&nbsp;altitude when it comes to DJI drones&nbsp;is most of the times written in the&nbsp;_Xmp.drone-dji.AbsoluteAltitude&nbsp;but it is sometimes written in the&nbsp;Xmp.drone-dji.RelativeAltitude&nbsp;tag.&nbsp;_

Our recommendation is to check the coordinates in the Image Properties Editor&nbsp; before running the project.

**&nbsp;- 2.b&nbsp;_BR`s EXIFExtracter_**

There is a freeware programme called&nbsp;\_BR`s EXIFExtracter (\_which can be easily downloaded&nbsp;[here](http://www.br-software.com/extracter.html)) which is able to create a .csv file including the GPS coordinates read from the XMP tags.

The steps to follow are:

- Open the software
- Select the folder where the images are located
- Select the name and folder where the .csv file will be saved
- Select the data to be exported: GPS latitude, GPS longitude, GPS altitude.
- Click on export

- [Create a new project](https://support.pix4d.com/hc/en-us/articles/202557309-Step-2-Creating-a-Project#label1)&nbsp;with Pix4D as usual
- Go to the[&nbsp;Image Properties Editor](https://support.pix4d.com/hc/en-us/articles/202557849-Menu-Project-Image-Properties-Editor-)
- Click on&nbsp;[_From File&nbsp;_](https://support.pix4d.com/hc/en-us/articles/205320215)and import the .csv file exported from&nbsp;_BR`s EXIFExtracter_

Best,
