Google Maps + Gallery

Shr00m: I've been working on that here and there. Are you using the module or the theme? I'll go back through and see what places I've missed in the module; it's really easy to end up dumping out characters that break the code when you've got PHP wrapped in Smarty generating Javascript inside an HTML document. ;-)

I have been following this thread for some time and have some spare time to implement it.
However the attachments don't seem to work. like in this post:
http://gallery.menalto.com/node/32642?from=50#comment-137189

Can somebody please attach the module and theme again. If that does not work send them to me and I will host them for download.

Cheers!

Perfect. Thanks
Must be this PC ... with XP the downloads dont work but in FF they do..... but on another machine (win2k) they download just fine. Another one for Bill to explain. ;-)

Hey, this is great. I was trying to implement something like this, and found that it has already been done. Great job.

One small hiccup: (I don't know if it is only me - please confirm). I am using the map-module. If any album name has a single quote in it, then I think the module breaks - i.e., no map rendering. It is too late tonight, almost 3am, so I don;t want to look at the code now. This is just a small (maybe) bug report.

I'm not sure I've addressed all the problems (in fact, I'm pretty sure I haven't), but here is version 0.1.3 of the map module. Please read the README; that's why it's called that. ;-)

I have fixed the problem with quotes in album titles, changed the date label to use whatever date format you specified in the "general" site admin section, added some parameter validation in the admin form, and commented the code a bit. The parameter validation is the only thing i'm worried about, since i haven't tested it exhaustively. If you have trouble, just open MapSiteAdmin.inc, go to line ~88, and comment out all of the code except the final "else" clause that saves the parameters.

I don't know what's causing it, but I do see the string "mapfiles" in code that Google provies. Like this, for example: http://maps.google.com/mapfiles/maps.23.js

How it's turning into a request from my server, I don't know...

Edit: In my logs, I'm getting occasional requests for /mapfiles/iw_tab.png and variations on the "tab" part. You can see that in the Javascript I linked to above. There's some variable "r" (the root of the webserver?) that gets set to another variable called _mStaticPath, but I can't find where that variable is initialized. I'd blame it on bad browsers messing up the Javascript, but I've seen it from both IE6 and Safari.

shocksll, Thanks for clearing this up. Now it makes much more sense to me.

Tried the new map-module-0.1.3 and it worked for me; however for now I kept the older
ShowMap.tpl in place.

I don't want to release a new version just for this, but if you open up your modules/map/module.inc and add this code (around line 72 or so, though it doesn't really matter), you can avoid having to fiddle with your .htaccess file to do the URL rewrite:

    /**
     * @see GalleryModule::getRewriteRules()
     */
    function getRewriteRules() {
        $rule=array();
        $rule['comment']='View Map';
        $rule['match']=array('view' => 'map.ShowMap');
        $rule['pattern']='map/';
        return array($rule);
    }

Once you've done that, just go into the Site Admin page for the URL rewriting module and hit the checkbox under "Map". You can configure the exact URL it will look for; by default it's just "map/" as on my site: http://severinghaus.org/gallery/map/

I am consistently surprised at how easy it is to work with the G2 code, now that I've gotten past the initial spike in the learning curve. Nice work, development team! :-)

I am happy to consider feature requests as long as those requesting features are not offended when I reject them. :)

I think could probably add a zoom link, though it would be non-trivial to replicate the functionality of the site you linked to. He has it set up so that when you zoom to a location, a different set of pushpins come up, which would involve storing a mapping between some high-level set of points and the points that should show up when that point is selected.

What would be easier is to first give the option of having the zoom slider show up, which I removed for no good reason, actually. When you have a pushpin selected and zoom in, it stays centered on that pushpin. The problem at the moment is that you have to keep hitting "+" until you get tot he level you want.

Second, you could have a sort of "secondary" zoom level that would be the zoom level to go to when you hit the "zoom in" link. That would be easy to do, and at least for me would cover most of the uses I would have for this sort of functionality.

By the way, this Google Maps EZ thing that is used on that site is pretty nifty if you haven't seen it.

For long term development, it would probably be good if this module first checked to see if a photo had GPS data in the GPS EXIF fields and autofill the custom GPS field.

While few cameras have GPS EXIF coding built in, there are a number of programs that will allow insertion of GPS data in to EXIF files based on time synchronization of a GPS track and EXIF time stamps.

A good summary of GPS tags in EXIF standard here:
http://www.sno.phy.queensu.ca/~phil/exiftool/TagNames/GPS.html
GPSLatitude
GPSLatitudeRef
GPSLongitude
GPSLongitudeRef
GPSAltitude
GPSAltitudeRef

EXIF 2.1 and 2.2 support location coding as follows:
Exif 2.2 specs:
http://www.exif.org/Exif2-2.PDF
GPS tags on page 52

Exif 2.1 specs:
http://www.exif.org/Exif2-1.PDF
EXIF 2.1(DCF Version) specs:
http://www.exif.org/dcf-exif.PDF
GPS specs on page 56-64 (acrobat numbers the pages 62-70) in both pdfs

It appears that issues with exifer tool utilized by G2 reading GPS out of EXIF tags has been resolved:

resolved here:

Thanks for the EXIF info, samkuhn2. I guess if we try to position photos based on their EXIF info, we'd need to cache it somehow. I think the EXIF module does this already, since there's a site admin function for refreshing the cache. I don't see anything obvious in my database schema that might store EXIF properties, though. Ideally, you could just query for all items that have the necessary GPS EXIF fields filled out and work with the results just like we currently do for the custom field.

I'll see what I can do about the problems with the "center on" validation. I tried a few reasonable values, and they all seemed to work. (For example, I use -40,40 as my default center.) The regexp is fairly complex, and it could well have problems:
/^[-+]?[0-9]{0,2}(\.([0-9]{0,12})?)?,[-+]?[0-9]{0,2}(\.([0-9]{0,12})?)?$/

If anyone sees anything glaringly wrong, let me know. I know it would technically accept the string "," as valid, but fixing that will be somewhat annoying, and I think it would be pretty obvious to the user that that was unacceptable. :-)

Just going to add a big thank you to everyone thats been involved with this especially HorsePunchKid!

Added the module to my site and after a lot of headbanging with the IE Operation Aborted problem when the gallery is embedded in wordpress. However thanks to Swordfish and Shocksll and their posts about this it's all sorted.

cheers folks

I think to prevent the "," string, this would do the trick:

/^[-+]?[0-9]{1,2}(\.([0-9]{0,12})?)?,[-+]?[0-9]{1,2}(\.([0-9]{0,12})?)?$/

Also I was also having problem with saving my center coordinate and it seems that the current regexp does not allow 3 digit numbers so I believe to fix both problems (the one mention above and this one) we should have something like:

/^[-+]?[0-9]{1,3}(\.([0-9]{0,12})?)?,[-+]?[0-9]{1,3}(\.([0-9]{0,12})?)?$/

It seems to have fixed all issues on my site :-D

Yea, cool! I'm definitely interested. Please upload and/or provide a link to download.
Your revised regexp worked for me too.

Thanks!

HorsePunchKid,
Try searching the GoogleMapki site.

Huge resource depot and map projects here.

I wrote the author of Google Maps EZ an email asking how he generated his icons. Given that Gallery is multilingual, if it is possible, it would probably be best to generate the pushpins on demand or on install based on the allowed language sets in Gallery. I have been looking in to how to do that with Imagemagick but have not yet finished testing out my efforts.

As I mentioned earlier, generating the pushpins on the fly, or at install with Imagemagick would be a boon in terms of both file management (fewer files to distribute) and more flexibility (different language fonts, universal hue/saturation/brightness).

When you create the custom field "GPS" it places it a tab in the edit section for either the image or the album. If you select "edit album" then click on the custom fields tab (matrix theme) you should be able to enter your GPS coordinates here which will create the link to the album with it's current highlight image.

That's how it works for me anyway.

Hello, well I'm glad I could help fixing a very small bug, sometimes just a new set of eyes helps

Anyways I have included as a download my version of the 0.2 code (I named it 0.2b) and the markers in two diffferent sizes

Changes compared to original version:
- MapSiteAdmin.inc now include the corrected Regexp
- ShowMap.inc include a query for the "color" field and include it in the "pointhash"
- ShowMap.tpl (I know I shouldn't have ... sorry) to select the icon to use on the fly depending on the selection made for each album marker

How to Instal this:
1. Unzip the content of map-module-0.2b.zip to overwrite you existing files
2. Unzip the content of map-marker-20.zip to a new folder under /gallery2/images called "map"
3. Add a "CustomField" called "color" and enter the list of possible value (to avoid errors later on)

When you enter your GPS coordinate into the Albums' CustomField, you have the option to select a color, if you don't select anything it will default back to the green marker.

One more thing: If you wish to use the "34" sized marker, you would have to edit Manualy the "ShowMap.tpl" file in the template directory of the module and modify the name of the iconImage:

albumIcon.image = "/gallery2/images/map/marker_20_{$point.color}.png";
Would become
albumIcon.image = "/gallery2/images/map/marker_34_{$point.color}.png";

Let me know if you are having any trouble :-D

Your 0.2b version works great, thanks! I was wondering if you could modify so in addition to an Album
the option of selecting a color icon for an Image can be chosen.?

Thanks!

In order to address the second issue the following can be used

/^[-+]?(([0-9]{1,3}(\.[0-9]{0,12})?)|(\.[0-9]{1,12}))(\040)*,(\040)*[-+]?(([0-9]{1,3}(\.[0-9]{0,12})?)|(\.[0-9]{1,12}))$/

This will then allow from 0 to 3 digit before the "." and from 0 to 12 digit after the ".", it will also prevent a string like ","

Btw it also allow for spaces before and after the "," just in case ;)

PS: included this change in the "c" version and re-uploaded it for easier install ("d" version now ....)

I heard back from the author of GoogleMaps EZ, Chouser. below is our discussion:

Here is his code:
http://bluweb.com/us/chouser/gmapez/gmapez.tar.gz

/*
* GMapEZ mkicons.pl -- creates custom icons for GmapsEZ
* Copyright (C) July 2005 by Chris Houser <chouser@bluweb.com>

* link to http://bluweb.com/chouser/gmapez/ -- this is a request, not
* a requirement. Thanks.
*/

Attached is the perl imagemagick script, the javascript for googlemaps EZ and the stock icon set.

I'm not clear how Gallery handles fonts, especially international fonts, and if that can mesh with the script above. Right now it relies on arialbd.ttf . As I mentioned in my previous post, ideally this script would support all the characters that Gallery supports.

I tried to directly attached the .tar.gz archive for this script to this message, but the forum balks saying that .tar.gz is an invalid extension. See the link above for the download set.

Quite, actually it looks like this: http://tinyurl.com/9vnp6

Also i attached an image which is explaining it better, i think. There you see that GoogleMaps is a subalbum, and i thought that i could link from evreywhere inside the other albums to this one. But you have your GoogleMaps-Album as a Root-Folder/Album, so maybe i have to set up a GoogleMaps-Album in the root of my gallery to be able to link from everywhere inside the tree, not outside the foldertree.

Run on install would be fine, although in that case you could just run it before distributing the package. I think more clever would be to run on demand so that a user can choose an arbitrary character/color/pin graphic. It would create a lot of small pngs just to cover common letters+symbols+colors+graphics for the most common languages. For an exhaustive library for all languages would be unachievable considering that UTF8 includes 2^16 chars. If the module is going to generate all the pngs on install, I would suggest it do that based on the installed languages in that Gallery.

I don't really understand how language specific font sets or symbols are handled by Gallery. It uses UTF8, but beyond that I am useless.

So ok, I believe that the best would be to have an update to the Admin panel so you could "regenerate" the icon at will with different character set or sizes or colors ....

I'm gonna start working on this, it seems quite interesting to do

HorsePunchKid: is it ok if I modify the code and create a new version with this included ? (like a 0.2.1 or something)

Let me know, I'm gonna get that started on my homework time
