[Google Maps API v3] Re: Google maps in Drupal

[Chris Apolzon]

I ran into an issue where I couldn't use the jquery selector object to
set the map variable.  I was forced to fall back to
document.getElementById().  It was very odd because jquery had the
correct object, the google maps constructor just didn't like it.

[Google Maps API v3] Re: Google maps in Drupal

[Chris Apolzon]

I have a working v3 map setup in drupal.  Could you provide more
detail about how you set it up?  This is really beyond the scope of
this group, so feel free to email me off the list.

Re: [Google Maps API v3] Re: JS errors in IE8 and IE7 when using OverlayView in Google Maps v3 API.

[Chris Apolzon]

I think the main culprit (slow IE) is IE's use of VML instead of SVG or
Canvas for graphics support.  IE7's javascript engine is also fairly slow,
but IE8's is really not that bad.
I do agree though, if you want a snappy-feeling map experience you cannot
use IE.  If you're supporting IE users, a recommendation of Chrome Frame
never hurts.

Re: [Google Maps API v3] Latitude and Longitude(X,Y) coordinates

[Chris Apolzon]

You can use the geocoder sevice.  I've had good luck getting locations of
villages in Africa (in the DRC specifically) without using a bias parameter,
but if you get weird results a bias will usually help clean the data up.

No, but if you just need JSON conversion, json2.js will do it for you much
cheaper than loading Prototype.

Re: [Google Maps API v3] Is This Allowed

[Chris Apolzon]

I'm no expert, but as long as your map isn't behind restricted
authentication or a firewall, it sounds like normal use of the API.

Re: [Google Maps API v3] a.lng is not a function

Looks like the latLngToDivPixel method takes in a point (a latLng object) so
try passing position in instead of lat.

Re: [Google Maps API v3] Re: Map Polygons stored extermally in an SVG file

[Chris Apolzon]

If you're just using SVG to externally store the data, you might find it easier 
to use a spatially enabled database (MySQL Spatial or PostGIS).  Unless you are 
looking for portability of data, in which case your SVG approach would probably 
be better (although PostGIS will allow you to dump your data into a shapefile 
or KML (I believe) format)

Re: [Google Maps API v3] Problem with V3 API on Droid

[Chris Apolzon]

I get a blank gray canvas (clicking the buttons does nothing) on Chrome on
OSX.  Maybe your successful test results were from a cached copy?

Errors that showed up in console:

Re: [Google Maps API v3] Problem using JSON object instead of array

[Chris Apolzon]

new google.maps.Point(0, 16));
You have an extra paren.  But please post a link to a sample post if you
really expect feedback from the group.  Additionally, using a developer tool
like Firebug would have pointed out this line as an error in the console.
(You may have other errors, but I stopped reading)

Re: [Google Maps API v3] Re: Cursor hot spot problem in Chrome

[Chris Apolzon]

Difficult to reproduce, but it seems to happen when you are near the left
edge, when toggling between hand and pointer, the pointer shifts its
alignment from the right of expected to the left of expected.  Much more
obvious when directly compared to Firefox.  Also seems to be more of an
issue on Windows than OSX.

Re: [Google Maps API v3] Re: 2010/03/03: New Release

[Chris Apolzon]

I would second the ability to be able to load the previous version of the
API.  I understand v3 is not stamped "production-ready" but in the rare
event when a new version breaks our code and we were set to demo
somethingwe're left out in the rain.

Re: [Google Maps API v3] Re: update spinner

[Chris Apolzon]

I think he's referring to the traditional "ajax is loading spinning wheel
graphic".  My guess is that it needs to be placed outside of map_canvas as
when you load the API, I'd think it more-or-less hi-jacks that div.

Re: [Google Maps API v3] A simple example with 'onclick'?

[Chris Apolzon]

You redeclared "var map" inside initialize.  Remove the "var" identifier 
inside your initialize function and it should work.

Re: [Google Maps API v3] Displaying several maps

[Chris Apolzon]

I think the best way to handle that is to actually have each map get its own
div and show/hide the div itself as opposed to trying to swap out which map
owns the div.  May the powers of CSS be with you ;)

Looks pretty good.  Any chance you could put a demo together that loads all

Re: [Google Maps API v3] Re: Building complicated polylines with multiple colors in multiple directions

[Chris Apolzon]

I ran into this same issue trying to render many complicated polygons and
polylines.  I have since migrated my code to use bratliff's polycluster
library.  I can't recommend it enough!  And the progress that has been made
over the past month has made it even better.

Re: [Google Maps API v3] Re: FYI: New Release (2010/02/03)

[Chris Apolzon]

Sorry, two more things I wanted to mention.  If you change the zoom level in
IE6 the polygon is not redrawn (performs as expected in IE7).  In IE6, the
polygon is white as opposed to the red color in IE7 (but the random polygons
on the source window are red in both browsers).
Hope this is helpful!

Also, interestingly enough, if you click examine, there are some random
triangular polygons showing up in the source window.  They stay put if you
move/scroll the window.  (I tried to find these on the actual map, but I
don't see them anywhere).

Re: [Google Maps API v3] Polylines with MVC array broken!

No polyline is created on load.  You have to click to add latlngs to the
path array.  It will auto-draw a line after you add the second point (by
clicking).  I tested in Chrome and it worked.

Re: [Google Maps API v3] Re: best practice

[Chris Apolzon]

I don't know of any tools for visualizing the data, but the mysql function 
astext(geometry) and asgeom(wkt_text) will help you convert between the 
internal format (geom) and wkt, which is what you'll want to process on.  If 
you want to visualize the data outside of google maps, I recommend looking into 
the ogr2ogr command-line utility which will allow you to export a mysql 
geometry table as a shapefile, which can easily be viewed using an open-source 
GIS tool such as Quantum GIS.  I just navigated this mess in the last couple 
months, so if you'd like more direct help, feel free to email me off the list.

Re: [Google Maps API v3] best practice

[Chris Apolzon]

If you will ever be doing advanced processing on the data (i.e. unions,
points on polys, etc.), I highly recommend a spatial-enabled MySQL setup (or
postgres (postgis) if you're willing to switch).  You can then get the data
out in WKT format, and its pretty trivial to convert this into processable
lat/lng pairs if you're using a backend scripting language.

Re: [Google Maps API v3] Re: How do I clear all the markers on the map

[Chris Apolzon]

I recall having issues with this when I first started using this version of
the API.  The only advice I can give is to make sure each new polygon gets a
new instance of an mvcarray for its paths.  I ended up writing a manager
class to ensure each polygon had its own "private" path and marker arrays.
 Otherwise, be sure to watch out for closure issues when declaring the
polys.

Re: [Google Maps API v3] Alternative JS include method

[Chris Apolzon]

Thanks.  The issue was exacerbated by my using two non-google libraries
which depended on the google api being loaded.  I've managed to get my
framework to play nice, so I'm now able to use the normal include method.
 (FYI: Drupal doesn't like remote js includes).  Thanks for the info though.

[Google Maps API v3] Alternative JS include method

[Chris Apolzon]

My current framework is unable to do remote js includes properly, so
I've resorted to a hardcoded "google.js" which consists of the initial
load code returned by the default remote inclusion line.  Obviously
this freezes me to a specific release of the API, but my issue is with
the geocoder service.  Whenever I use the hardcoded js API include, my
geocoder requests are denied stating:
Your client does not have permission to get URL /maps/api/js/
GeocodeService.Search?query=

Is there any way for me to use a non-remote copy of the API and still
have access to the geocoder service?

Thanks.

Actually, that terrain map is pretty close to what I need.  I actually don't

clean maps of Africa, I'm happy.
Thanks again for looking into this.

[Google Maps API v3] Re: Encoded polylines vs Polyline class

[Chris Apolzon]

I'm wondering if I can speed up my map by passing a pre-encoded
polyline into the polyline constructor instead of letting google
encode it.  I haven't seen anything in the v3 documentation about
forcing the use of an encoded polyline, is there a workaround to allow
this to happen?  I'd be fine abandoning the polyline class if
necessary.

Do you have a sample page you can point us to?

Re: [Google Maps API v3] What IDE to use for javaScript

[Chris Apolzon]

There aren't many ides that offer js code completion purely by nature of the 
language.  For the most part, you need a custom file for code completion in 
each framework.  I've seen this done in komodo edit for the more well-known 
frameworks, but I believe you'd need to find something custom for the gmap api.
Unfortunately I don't know too much about gwt so hopefully someone else will 
respond to that part of your question.

Re: [Google Maps API v3] How to add listener for overlays

[Chris Apolzon]

I haven't tried doing this with an overlay but if you can afford to use a 
polygon instead, I can confirm that will work.  As a fallback I believe you 
could surround the overlay with a transparent polygon.

re: [Google Maps API v3] Markers problem

[Chris Apolzon]

It looks like you are using the v2 google maps api, so you should probably post 
your question in that mailing list instead.When I loaded your map, I get a map 
is not defined error on line 48 (map.addOverlay(marker162900);).  I'm not sure, 
but it looks like your cdata section ends just prior to this line, so I would 
take a look at moving the cdata endpoint to below the end of your script if 
possible.

re: [Google Maps API v3] Re: map misbehaves on iPhone

[Chris Apolzon]

In regards to the missing + and - zoom buttons, I seem to recall that v3 sniffs 
out the browser and applies certain "native" behaviors to the map.  I think you 
can explicitly ignore this, but I don't remember the syntax for doing so. (some 
sort of query parameter?)

Here are the experiences in v2. I quote a friend (since I don't own an

"This is so f***ing entertaining! The + and - zoom buttons do not work

the view a little bit. Double tapping to zoom in is now a disaster,
and lands me in random places, such as the southern coast of Sweden
[we start in Germany]. LOL!!! Oh, the "view" drop-down menu does work
on the iPhone, but it's somewhat hard to tap the tiny choices. Love
that "terrain" view.

But the + - buttons work nicely on my PowerBook in Safari, interesting
to see the layout in a regular browser.

Deleting the mileage scale is an unfortunate loss."


This is the first time I am trying to embed maps for the benefit of
iPhone users. Does it have to be this bad? Is there sample code
somewhere that works? I don't care which version of the API.

re: [Google Maps API v3] how to get the draggable marker's new position

[Chris Apolzon]

You should hook into the dragend event and look at marker.getPosition().
Here's a snippet taken from one of the code samples: 
google.maps.event.addListener(marker, "dragend",   function() {for (var 
i=0, I = markers.length; i < I && markers[i] != marker; ++i);path.setAt(i, 
marker.getPosition());   }  );Obviously, this is taken from a polygon demo.  If 
you only have points, you should be able to simply call marker.getPosition()

[Google Maps API v3] Re: Multiple Polygons

[Chris Apolzon]

It looks like redeclaring my map variable was what was causing the
havoc.  The following code performs as expected:

path_options.map = map;
path_options.paths = top_path;
var top_shape = new google.maps.Polygon(path_options);

google.maps.event.addListener(top_shape, "click", function()
{ alert("top_shape");});

path_options.map = map;
path_options.paths = bottom_path;
var bottom_shape = new google.maps.Polygon(path_options);

google.maps.event.addListener(bottom_shape, "click", function()
{ alert("bottom_shape");});

(Both shapes are rendered, and clicking on a shape yields the
appropriate shape popup).  I guess I've answered my own question, but
I figured I'd post this here in case someone else is running into a
similar issue.

I was able to get both polygons rendered by setting the paths variable

to attach a different infowindow to each polygon and I believe this
solution results in one polygon with 2 paths (which happen to not

I'm not sure exactly what I'm missing here.  I have this code
executing as an onclick event on a button.  When the button is
pressed, you see the second polygon (only).  If you hit it really
fast, you can see both polygons on the map prior to the layer being

disappearing as the second is drawn.


map = new google.maps.Map(document.getElementById("map"),
map_options);
path_options.paths = top_path;
var top_shape = new google.maps.Polygon(path_options);

top_shape.setMap(map);

map = new google.maps.Map(document.getElementById("map"),
map_options);
path_options.paths = bottom_path;
var bottom_shape = new google.maps.Polygon(path_options);

bottom_shape.setMap(map);
