If the GPS status field says “measurement void” then why is your software reading the rest of the GPS fields?

None of my software products seem to know that you suppose that "v" stands for "void". This is becoming - immature.

GPSStatus Indicates the status of the GPS receiver when the image is recorded. 'A' means measurement is in progress, and 'V' means the measurement is interrupted.

from:

Standard of the Camera & Imaging Products Association
CIPA DC- 008-Translation- 2012 Exchangeable image file format for digital still cameras:
Exif Version 2.3

Pop,

 

What piece of software shows you that exif data with a GPS field?

On the Apple I use the standard image viewer and press Command-I.

...while the display I showed earlier in this thread:

 

This is the EXIF entry I see when viewing an OOC Jpeg taken with an M (Typ 240) which has no GPS device attached:

 

attachicon.gifBildschirmfoto vom 2017-10-23 12-42-07.png

was produced using the standard image viewer in Ubuntu Linux. When the image is on display, select "show image properties".

I’m not understanding what you mean by “reasonable”.

 

The reason I asked is someone above made a statement about Leica showing wrong information and all Leica does is populate fields with data.

I used the term "reasonable" in reference to the software which populates my elderly Windows XP; some of that software would display part of the GPS EXIF data, but not all of the fields. That's not "reasonable", in my opinion. However, in the same post I mentioned software both for Mac OS and Linux which does display the data under discussion in a useful manner.

 

The Leica M (Typ 240) populates the GPS part of the EXIF fields with data that is clearly wrong.

I don't think there is a GPS device for the M9 which can write into the files of the M9; hence, the M9 ought not to have this problem. Indeed, the pictures I made with my M9 don't have any GPS data embedded.

 

I can not comment on the 5D or the M10, as I don't have access to either.

The only fields the camera GPS, if there is one, populates is latitude, longitude and elevation and anything proprietary to the GPS. I think those other fields are populated by the third party software in an effort to populate an empty field until corrected or edited by the GPS.

An M 240 provides the following when a GPS is active

GPS Version ID                  : 2.2.0.0

GPS Latitude Ref                : North

GPS Longitude Ref               : East

GPS Altitude Ref                : Unknown (45)

GPS Time Stamp                  : 14:01:11

GPS Status                      : Measurement Active

GPS Dilution Of Precision       : 1.8

GPS Speed Ref                   : km/h

GPS Speed                       : 0

GPS Track                       : 0

GPS Date Stamp                  : 2014:10:15

GPS Altitude                    : 62.4 m Below Sea Level

GPS Date/Time                   : 2014:10:15 14:01:11Z

GPS Latitude                    : 51 deg 11' 38.82" N

GPS Longitude                   : 0 deg 3' 29.74" E

GPS Position                    : 51 deg 11' 38.82" N, 0 deg 3' 29.74" E

 

And when the GPS is void

GPS Version ID                  : 2.2.0.0

GPS Altitude Ref                : Above Sea Level

GPS Time Stamp                  : 00:00:00

GPS Status                      : Measurement Void

GPS Dilution Of Precision       : 0

GPS Speed Ref                   : Unknown ()

GPS Speed                       : 0

GPS Track                       : 0

GPS Date Stamp                  : 2017:10:23

GPS Altitude                    : 0 m Above Sea Level

GPS Date/Time                   : 2017:10:23 00:00:00Z

 

Some software ignores the GPSStatus field. That's not Leica's fault. Violets indeed.

'A' means measurement is in progress, and 'V' means the measurement is interrupted.

 

Measurement can be interrupted by foliage and buildings and so on. That's quite another discussion: what the camera is to store between measurements.

In the screen shots given above, the fields populated are faithfully reported by the software showing the fields. They are, of course, defined by the consortium which defined all of the EXiF fields, also mentioned above.

The GPSStatus field does not contain the value "Void". It contains either an "A" or a "V". The interpretation of "V" standing for "Void" is not supported by any of the CIPA documentation. The meaning given there is "measurement interrupted" or "measurement interoperability", whatever that means. Further, there is no documentation stating that the whole GPS record or specific parts are to be ignored in the presence or absence of particular field values. 

 

What would be more straightforward than not including a GPS record when there is no GPS data available?

 

I have found only one reference to the term "void" with reference to the GPSSTATUS field. It seems to have been invented by the maker of a software which displays the EXIF information contained in a picture.

Which GPS field do you speak of.

 

All GPS fields you see are by third part software makers. They populate the fields with data from the image. It is the choice of the software writer from the third party maker what information to put there. Leica doesn’t build those fields or their interpretation.

I speak of the fields depicted in my post above: https://www.l-camera-forum.com/topic/277785-geotag/page-1?do=findComment&comment=3380719

 

Those fields are there when the file leaves the camera. The Leica M (Typ 240) writes the fields into the EXIF data of the files. The fields are reasonably well formed, but they contain false data.

I disagree.

 

All that leaves the camera attached to the photos are strings of raw data.

 

Third party photo editing software contain fields that are populated with that data. Leica has no published photo RAW converters or image editing software as far as I know.
