asGPS: a geocoding plugin for ASP

[binoyte]

many thanks ! By the way I'll try to update the French translation which is perfectible.

Regarding the problems in zenPhoto: This looks like a zenPhoto problem. If you look into the exif data with exiv2, you will see the correct rationale values for the position. There is no chance to code the "N", "W" etc. into this exif fields. Also Darktable displays my test images in the correct position. They also show up correctly in panoramino / google maps.

There may be a ref problem in asGPS with negative altitudes. I will correct it in version 1.3.3.

There is no chance to code the "N", "W" etc. into this exif fields.

In fact they already are. I tried this command :

Code: Select all

$ exiv2 -pv misplaced.jpg  | grep GPS
0x8825 Image        GPSTag                      Long        1  424
0x0000 GPSInfo      GPSVersionID                Byte        4  2 3 0 0
0x0001 GPSInfo      GPSLatitudeRef              Ascii       2  N
0x0002 GPSInfo      GPSLatitude                 Rational    3  46/1 41/1 37080/6000
0x0003 GPSInfo      GPSLongitudeRef             Ascii       2  W
0x0004 GPSInfo      GPSLongitude                Rational    3  73/1 1/1 1079/6000
0x0005 GPSInfo      GPSAltitudeRef              Byte        1  0
0x0006 GPSInfo      GPSAltitude                 Rational    1  301/1
0x0009 GPSInfo      GPSStatus                   Ascii       2  A

It seems indeed this is a zenPhoto problem.
By default exivtool or exiv2 translates the exif. The

-pv

option shows plain exif.

Thanks for the time on my problem.

I did some further checks with zenphoto. I made some changes in asGPS regarding the altitude ref and reexported my test image. Now it was imported correctly into zenphoto. I checked, which values had changed and both exiftool and exiv2 report that the GPS values did not change at all. I tried with the already imported image, exported it and reimported it: wrong position. All new created jpegs: good position. Currently i cannot reproduce the problem.

Exif in zenPhoto when GPS is displayed:

wrong positioned image

Code: Select all

Breitengrad:	56,48166662037
Breitengradreferenz:	N
Längengrad:	6,1498333333333
Längengradreferenz:	Ws`
Höhenlage:	3m
Höhenlagereferenz:	008d9d60

image with correct position:

Code: Select all

Breitengrad:	56,48166662037
Breitengradreferenz:	N
Längengrad:	6,1498333333333
Längengradreferenz:	W
Höhenlage:	3m
Höhenlagereferenz:	00c7e008

What is shown in your images?

Here is my workaround. I added the substr function in two lines in zp-extension/GoogleMap.php:

Code: Select all

/**
 * $eturns coordiante information for an image
 * @param $obj
 */
function getGeoCoord($obj) {
    $result = false;
    if (is_object($obj) && $obj->table == 'images') {
        $exif = $obj->getMetaData();
        if(!empty($exif['EXIFGPSLatitude']) && !empty($exif['EXIFGPSLongitude'])){
            $lat_c = explode('.',str_replace(',', '.', $exif['EXIFGPSLatitude']));
            $lat_f = round((float) abs($lat_c[0])+$lat_c[1]/pow(10,strlen($lat_c[1])),5);
            if (substr($exif['EXIFGPSLatitudeRef'], 0, 1) == 'S') {
                $lat_f = (float) -$lat_f;
            }
            $long_c = explode('.',str_replace(',', '.', $exif['EXIFGPSLongitude']));
            $long_f = round((float) abs($long_c[0])+$long_c[1]/pow(10,strlen($long_c[1])),5);
            if (substr($exif['EXIFGPSLongitudeRef'], 0, 1) == 'W') {
                $long_f = (float) -$long_f;
            }
            $result = array('lat'=>$lat_f,'long'=>$long_f, 'title'=>$obj->getTitle(), 'desc'=>$obj->getDesc());
        }
    }
    return $result;
}

This resolves the problem vhen refs are messed up. But the original problem remains: Who messes the ref values? ASP or php-exif or somethink in the zenPhoto database import?

Wow what a workaround !

What is shown in your images?

Same as you ! I've weird types after N/S E/W And I wonder about the relevance of the EXIFGPSAltitudeRef datas. Here is a screenshot of my mysql datas : http://tmp.benoitvarret.fr/misplaced_phpmyadmin.png

Thanks for your hack. I'll refer it on ZP forum : http://www.zenphoto.org/support/topic.php?id=14205

[andreas]

so, asGPS version 1.3.4 is now compiled locally (lin/win). Waiting for the mac version. negative altitudes are now handled correctly - regarding the messed up options/exif mix in ASP.

Andreas

[andreas]

I sent a post regarding these problems to the mentioned zenphoto thread

Andreas

[andreas]

Thanks to Jonathan for the mac version.

Current asGPS v1.3.4 is available using asPluginManager or directly from the Corel plugin page: http://aftershotpro.com/plugins/index.html?plug=asgps

Andreas

[binoyte]

Doesn't work for me. The map is still "locked".

[andreas]

the info dialog shows 1.3.4?

[andreas]

sorry old html page included, will update the link.


EDIT: no, this is not the case. Yesterday I tested with just this version which worked. Digging into it...

[binoyte]

yes : 1.3.4 http://i38.servimg.com/u/f38/13/98/61/29/captur11.jpg

By the way, I found what's wrong with zenPhoto. Thanks for your help.

[ogrizzo]

yes : 1.3.4 http://i38.servimg.com/u/f38/13/98/61/29/captur11.jpg

Same here: pane still freezed, version 1.3.4, running OSX 10.8.2
