Module: EXIF GPS

I'm not entirely sure why guys, but trying to display a map of GPS coordinates for all of my pictures does not work (it loads and shows an empty space where you would expect the map), while I've confirmed that smaller albums work fine. I upgraded to the latest version of the plugin that's attached in the previous post and dumped my exif_coordinates table and ran the extraction again, so I'm not sure what's going on. Any ideas?

Hello

whould you support Openstreetmap.org as aditional layer? or use maybee openlayers from OSM without google api?

Hello all. I have been using Gallery for all of 4 hours so does the word newbie mean anything to you?

Thank you so much for such a great piece of software and an amazing module. I downloaded this EXIF GPS module and installed it without a problem.

At the time of the installation, I only had 5 photos in 1 album that were added with the Server Add option. When I ran the maintenance to have this module extract the information from my existing photos, no map or anything was shown on the page.

I deleted all the photos from the album, did the Server add again and Voila! The map and everything was there.

Did I do something wrong? Why didn't the information come across without having to delete and reimport the pics?

Thanks in advance and thanks again for this brilliant module.

Sorry for this, I now see, that it's working if I click on Map * , but somehow the overview map is no not showing anymore. I will have a look at this during the evening. And provide a german translation for the map* links. I thought this would be for mapping an entire album.

Cheers Eyeless

i activated the error report:

This module was not installed, and installing exif_gps did not triggered any dependency warnings... i installed tagsmap and now i have no error anymore.

Thanks !!

I have a lot of images in my gallery and want to geo-tag many of them manually. For this, I search the locations on google-maps and copy the google-map-links. The latitude and longitude are coded in this Google links like this: ...&ll=1.234,5.578&....

It's strenuous to copy the latitude and longitude and paste it separate into the accordant fields in gallery.

To speed-up this task, i have added a third field for the complete google-maps-url and extract the latitude and longitude after the submit:

modules/exif_gps/helpers/exif_gps_event.php

    if ($record->loaded()) { 
      $gpsdata->input("latitude")->label(t("Latitude")) 
           ->value($record->latitude); 
      $gpsdata->input("longitude")->label(t("Longitude")) 
           ->value($record->longitude); 
    } else { 
      $gpsdata->input("latitude")->label(t("Latitude")); 
      $gpsdata->input("longitude")->label(t("Longitude")); 
    } 
    // additional field: 
    $gpsdata->input("googleUrl")->label(t("GMapsURL"));

    // ...

  static function item_edit_form_completed($item, $form) { 
    // Update the db records with the user-specified coordinates. 
 
    // additional code: 
    if (preg_match("/(\&|\?)ll=(\-?[0-9\.]+),(\-?[0-9\.]+)\&/",$form->edit_item->gps_data->googleUrl->value,$coordinates)){ 
      $form->edit_item->gps_data->latitude->value = $coordinates[2]; 
      $form->edit_item->gps_data->longitude->value = $coordinates[3]; 
    } 
    //...

I've noted a bug in exif_gps. The 'Map This Album' feature does not display in some circumstances. From my testing it looks like it doesn't work if there are sub-albums of the album being mapped, however this is not consistent. It could be due to the number of items within each album but I have not been able to do enough testing to confirm that.

Test1: Sub-album contains ~400 images, maps fine.
Test2: Parent album contains 26 sub-albums (totalling ~2500 images), produces no map output.
Test3: Sub-album contains ~400 images and one sub-album containing a single image, maps fine.
Test4: Parent album contains a single image, 26 sub-albums (totalling ~2500 images), produces no map output.

Note that the side-bar map works consistently in all cases.

Any advice appreciated.

Does this help?

This is really a great module, and to be honest, this module made it possible that I switched from 4images to Gallery3

In Addition to the normal function of the module I display a bigger map under the foto.

I copied the code into the photo.html

<script type="text/javascript" src="http://www.google.com/jsapi?key=<?= module::get_var("googlemap_api_key"); ?>"></script>
<script type="text/javascript">
    function initialize() {
    var latlng = new google.maps.LatLng(<?=$latitude; ?>,<?=$longitude; ?>);
    var myOptions = {
      zoom: 20,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map(document.getElementById("sidebar_map_canvas"),
        myOptions);
  }

  google.setOnLoadCallback(initialize);

</script>
  <div id="sidebar_map_canvas" style="width:800px; height:400px"></div>

I know this way is not the best option, but for me it is working.

Is there any way that I can set my own options for Zoom and Maptype, because does not matter which options I set in var myOptions, always the values from the module are used.

I also tried to rename (document.getElementById("sidebar_map_canvas") and <div id="sidebar_map_canvas" to another map_name but in this case there is no map displayed.

Thanks in advance

You can use an API console key instead:

Hello there.

Is it just me or is this addon currently a bit out of date? After following the installation instructions and enabling both addons (exif and exif_gps) I get no sidebar whatsoever when I open an image which I know contain EXIF GPS data. When configuring the addon, it asks me for the Google Maps API key - which I know is deprecated. So I'm wondering if the addon perhaps needs an update?

Or am I missing something...?

Does the docs need to be updated. I can do this if somebody makes a suggestion if they don't feel comfortable doing so.

It seems to be related to the volume of data produced. I can make things work alright if I modify exif_gps_map.html.php to only add more than one picture at a given coordinate if there aren't too many, ie:

      <? } elseif (count($items) < 500) { ?>
        <? $windowContent = $windowContent . " <div class=\\\"g-exif-gps-thumb\\\"><a href=\\\"" . 
                            $item->url() . "\\\">" . 
                            str_replace("\"", "\\\"", $item->thumb_img(array("class" => "g-exif-gps-thumbnail"))) . 
                            "</a></div>"; ?>
      <? } ?>

Additionally, since each call to glatlngbounds.extend seems to produce some javascript, rather than calling it for each item, it reduces the amount of data to only call it if the coordinates have changed.
Still, I have no idea where the limitation is here...some aspect of PHP's output buffering?

rWatcher, any opinions on these changes?

Would it be possible for you to post a sample photo with non-working coordinates so I can try and debug this?

v3 looks great but hasn't been all that happy so far on my machine. Hitting the map button for an album leads to an error about items being undefined on line 121 of exif_gps.php. I don't know enough php to tell what might be going on here...I don't see another items variable in scope. Trying to hit the save button on the settings page leads to an error on line 57 of admin_exif_gps.php about an undefined offset of 0.

On an unrelated (I think?) note I had to add a couple of 'static' annotations to the _can_view_profile_pages routines in rwinfo_theme.php and rwinfo_block.php for the rwinfo module (I think I picked up a new version as well when I git pulled from gallery3-contrib).

Any ideas?

Yup, that looks good now.

That error was still there but I was able to work around it by checking isset in the loops in question, ie:

      if (count($form->Global->toolbar_map_user) > 0) {
        for ($i = 0; $i < count($form->Global->toolbar_map_user); $i++) {
          if (isset($form->Global->toolbar_map_user->value[$i]) &&
              ($form->Global->toolbar_map_user->value[$i] == "checkbox_user")) {
            $checkbox_user = true;
          }
        }
      }

As I said, I don't know php so I don't know what the rules are, but this seems to make it work. I run Debian Unstable which seems to have a newer version of php than most (php5 5.4.4-rc1) and I've had to make a few changes to G3/modules to make it happy.

With all of this, the new version looks great! It seems to choke up a little when trying to map tens of thousands of points, but works on more reasonable requests.

One other problem: putting the “Exif GPS Maps” block in the sidebar causes none of the sidebar to be displayed, but I don't see any errors at all in either the web server log or the G3 log. The “EXIF GPS Location” block works fine however.

Thanks for an awesome module!

I'm hesitant to necessarily say it's a bug in the module - watching the server, I see apache and mysql spin for a while as the client says "loading." When that's done it thinks for a bit and a few markers appear. At some point later some more markers might appear as well, but it seems like sometimes not all of them do. So it could be some weird quirk on the client side as well. I'll try to poke aronud at it some more and see if I can characterize it.

The download link is giving me a "page not found" now. Anyone else?

The new module version does fix the problems I was having saving the settings, thanks. The sidebar is still broken, however, with nothing in the webserver or g3 logs. This isn't a big enough deal that I'm inclined to spend any time on it, but am happy to try anything if you have suggestions.

It doesn't seem to me like it's a php timeout - the server spins for a little over a minute when querying my whole gallery (timeout should be two minutes) and there are no errors in my logs. After the server stops processing, the client displays a couple of individual markers for pictures, but no clusters, and is not consuming CPU. Sliding the map around with the mouse causes it to display the clusters, although not necessarily all at once.

A different error I just started getting: Sometimes the map instead displays “An AJAX error occured: parsererror\nError: undefined.” Nothing in either log.

As a side note, while the server is processing, it seems like the majority of CPU time (80%?) is in the apache process which implies that the database query is not super expensive, but the php processing is?

This is on a gallery with about 45,000 images, of which about 16,000 have EXIF coordinates.

I'm unable to reproduce this on my end. What version of Gallery are you using?

Sounds like it's having trouble processing the XML data. Either there's a character in there that's not being escaped properly (shouldn't happen, but you'd get this error every single time if it was the issue), or else maybe php is cutting out in the middle of printing the XML data, causing errors that way.

I've updated the module to process records 1000 at a time instead of all at once, so if something is timing out, this should fix it. I've also added a "% complete" counter onto the "Loading..." message -- should make it easier to see if it's still loading or not.

"Show Map this album icon?" and "Show Map this user icon?" control the display of icons at the top of the page, not the sidebar links.
[img]http://gallery.menalto.com/files/exif_gps_map_icons.png[/img]
If you wanted to remove the user link from the sidebar, you'd have to manually delete lines 6-8 in /modules/exif_gps/views/exif_gps_maps_sidebar.html.php.

I seem to be having another issue...

My sidebar maps now load to either 53% or 93% then blank out to a grey map with absolutely nothing displayed when I'm at or near my root folders. If I drill down all the way inside an album with say 100 pictures in it, it starts working.

I've added about 1300 pictures from my trip to Italy, and it seems to have killed it. I have somewhere around 2000 pictures that are location tagged.

Any ideas? I've already set my max execution time to 900 seconds.

Can I rebuild the exif gps database? If so.. how?

Thanks for the PM rWatcher - I'm good now. Thank you!

For the rest of you with maybe similar issues - I have a 5Dmk3 with the GP-E2 module tagging my images. I was getting invalid geolocation from the GP-E2 module when it was running more than 90* vertical. For example, I was in the Vatican taking pictures in the museum areas looking up. The problem I was having is that when the GP-E2 goes more than 90*, it freaks and gives invalid data.

*Nevermind* I didn't have the latest version of Gallery 3 installed. Installing that fixed my issues. I'll leave this post, in case someone else has this issue.

I am trying to convert from G2 to G3, and have been running both in parallel for quite some time, waiting on something like this to completely my transition to G3. I have the side bar working perfectly, where I can see and interact with the mini map. I've setup a Google API key for it, though I'm not sure if it needs a Browser or Server key. I'm pretty sure I've enabled the V2 and V3 APIs along with the Static Maps API. The mini map on the side bar is great. If the end map works like that, I'm impressed enough to leave my G2 site behind.

However, my problem is with the larger map. When I click Map this Album in the main album, I get a 500 error in Chrome and IE. If I use the shortcut at the top for viewing the map, I get the google map, but no data points on it. I was getting an api V2 error in IE at one point, so I'm pretty sure I have the API key, but I"m unsure why the behavior of the shortcut is different than the Map this Album link, and why neither is working. I downloaded the latest copy from this forum and installed over top of the previous version. Any other ideas?

I've posted an Updated version of EXIF_GPS, which includes bozek's fix for excessive database queries, as discussed here:

The updated module can be downloaded from the first post, or my github account.
