nextgen geo – map not displaying

You have to add the plugin tag, otherwise your post is not related to the plugin.

Does it work if you deactive the worldmap-mode? Please try the newest trunk-version also.

Hi,

I have the same kind of errors.

So I tried with starting a blank new project using WordPress (english) 3.3.2
Only plugins installed :
NextGen Gallery, version: 1.9.3
NextGen Gallery geo, version : 0.60
All running locally with MAMP (on Mac, OS X Lion)

Only one post ! With [nggallery id=1] [nggg]

Before I tagged the post, I had the same error as Aviceda.
Once the post tagged, I have the same error as alternateroute.

I am not sure what we should understand by “You have to add the plugin tag, otherwise your post is not related to the plugin.” ?
Do you mean to add a tag for the post like “nextgen-gallery-geo”.
Whatever, it’s what I did.

When trying to update the options of the plugin, I get again the error message :

Cannot modify header information – headers already sent by (output started at /…/wp-content/plugins/nextgen-gallery-geo/example.php:145) in /…/wp-includes/pluggable.php on line 866

and I get a full list of errors for the preview map.

I get the same message if I do an update for the post.
If I display the post, I get a list of error :

Notice: Undefined variable: map_output in /…/wp-content/plugins/nextgen-gallery-geo/plugin.php on line 25

Warning: exif_read_data() [function.exif-read-data]: Unable to open file in /…/wp-content/plugins/nextgen-gallery-geo/functions.php on line 24

Notice: Use of undefined constant latitude – assumed ‘latitude’ in /…/wp-content/plugins/nextgen-gallery-geo/functions.php on line 67

etc… for several lines…

I like very much the concept of this plugin and sure be very useful.

Let us know, if our problems come from some setup mistakes we do or misunderstanding from our part, or if these errors that come out need code corrections.

Thanks for your answers.

Please try the trunk version, I have allready deleted the blank lines.

Thanks for your patience and the detailed informations, I will try to fix it later this day. V. 0.52 should work.

It’s not an error, just a notice. The most configurations does not display these notices. But I will try to fix that, too. 😉

@capecross: added the “?>”, stupid bug.

Hi Frederic,

Until now I had no better results.
Either V.0.52 or V0.61.
I think I have an explanation, see below…

As in the settings, I could see the example map, but no result in post, and as I am sure all this is working for you, I thought it could be a configuration problem.

Then I had the idea to make a try with your example images, even if I was sure that my images had GPS datas.
So I imported your example images in a Gallery, and post, and then the map and the vignettes showed nicely.
So this surely meaned that there were differences in the exif datas.
Using Phil Harvey’s exiftools I compare :

Here is one of your image exifs datas as it is shown by exiftools :

Resolution Unit : None
Y Cb Cr Positioning : Centered
GPS Version ID : 2.2.0.0
GPS Time Stamp : 20:36:14
GPS Satellites : 0
GPS Map Datum : WGS-84
GPS Date Stamp : 2012:05:11
XMP Toolkit : Image::ExifTool 8.26
……some more datas…..

Y Cb Cr Sub Sampling : YCbCr4:2:0 (2 2)
GPS Date/Time : 2012:05:11 20:36:14Z
GPS Latitude : 44 deg 29′ 34.40″ N

GPS Longitude : 63 deg 54′ 59.40″ W
GPS Longitude Ref : West
GPS Position : 44 deg 29′ 34.40″ N, 63 deg 54′ 59.40″ W

Here is one my images (made with a Canon camera) exits datas as it is shown by exiftools :

Exposure Mode : Manual
White Balance : Manual
Scene Capture Type : Standard
Lens Model : EF24-105mm f/4L IS USM
GPS Version ID : 2.2.0.0

……some more datas…..

GPS Latitude : 65 deg 48′ 28.87″ N
GPS Longitude : 16 deg 23′ 13.78″ W
GPS Position : 65 deg 48′ 28.87″ N, 16 deg 23′ 13.78″ W

Shutter Speed : 0.4

I usually use PhotoLinker to reverse geotag my images, before importing them to Lightroom, then exporting them for the web with all the metadatas.
Now that Lightroom 4 handles GPS datas, I might skip PhotoLinker.
But anyway there is a difference between the way GPS exifs are coded within your images and mines.
Especially the lack of GPS Date Stamp and GPS Date/Time in my image and the order.

I made a try with an image made with another camera (Panasonic), and your map shows OK. The GPS datas came from a gpx file used with PhotoLinker to tag the images.
The exif tools shows :

Lens Model : LUMIX G VARIO 14-140/F4.0-5.8
GPS Version ID : 2.2.0.0
GPS Latitude Ref : North
GPS Longitude Ref : West
GPS Altitude Ref : Above Sea Level
GPS Time Stamp : 16:42:01
GPS Map Datum : WGS-84
GPS Date Stamp : 2011:06:16
Compression : JPEG (old-style)
……some more datas…..
Aperture : 5.0
Date/Time Created : 2011:06:16 16:42:28+02:00
Digital Creation Date/Time : 2011:06:16 16:42:28+02:00
GPS Altitude : 17.9 m Above Sea Level
GPS Date/Time : 2011:06:16 16:42:01Z
GPS Latitude : 65 deg 31′ 32.22″ N
GPS Longitude : 13 deg 48′ 20.04″ W
GPS Position : 65 deg 31′ 32.22″ N, 13 deg 48′ 20.04″ W
Image Size : 940×587

So I do think my problem was coming from this.
Datas are not arranged in the same way or order.
I should have a look in the data base to try to understand, or modify your test :
line 28 in functions.php :
if (!isset ($exif[‘GPSLongitude’][0])) {return false;}
which maybe is toot strict.

If you have ideas from your side…they will be welcome.

Sorry to have been so long, but I am almost sure, I won’t be the only one to face this.
Hard time with these exifs which are not completely normalized…

“Can you please mail me a photo?”

Email sent !

Several tries later, I am not quite sure that’s my problem come from the way GPS datas are arranged, or has something to do with the lack of GPS Date Stamp and GPS Date/Time…
