Map Channels v4.11 released: including support for changes to Google's My Maps service

See this guide about the recent changes to the New Google My Maps and how these affect your maps created through Map Channels.

The changes to Map Channels v4 comprise a set of additional options in the 'Categories' section. Please check your maps to make sure that they are displaying properly. Use the new options to update your Map Channels if your maps have been affected by the recent changes. The new code version will be applied automatically when you update your v4 Map Channels.

If you have any questions about the changes or would like an archived feed restored please contact us.

Venue Maps

Venue Maps is a project to display maps and street view for any location. Users who sign in with their Google accounts can save places from a Venue Map to view later on the main Google Maps site and mobile apps.

The code originated on Map Channels Events and Map Channels Hotels to map venue and hotel locations.

Venue Maps provide two maps at different zoom levels plus a street view where this is available. There are options to configure the appearance of the maps and street view and also to select specific street view co-ordinates, heading, pitch and zoom.

Visit the Venue Maps page to get started.

Venue Maps

The code includes the new Google Maps 'signed in' feature which allows users who are signed in through their Google account to save the placemark location and URL. This feature is a great way for visitors to bookmark your placemark location and website in one go and to return later via another Google Map.

The format for Venue Maps is different to most other Map Channels projects. Rather than using a small section of iframe code, Venue Maps provides the full source code required to implement the map inline on your web page. Inline display of the map is the best approach since the street view section is not always displayed and can be hidden by the user.

It is recommended to log in to Map Channels before creating a Venue Map so that your map settings will be saved for future reference. The settings for the most recent map created are saved for each user.

The code is provided with an open source Apache license. Please include a link to Map Channels on the page where the map is displayed. A Map Channels link is helpful for us to get more visitors and also for you as a bookmark if updates are made to the code.

Map Channels v4 Update

Changes have been made for Map Channels version 4:

1. Data from the new Google My Maps can be used as feeds.
2. KMZ feeds are now supported. KMZ files are compressed KML files which can also contain other assests such as markers.

Switching to The New Google My Maps

Update, 18 Nov 2014

Since writing the notes below it looks as if all Google My Maps have been upgraded to the new version whether you want it or not, so the notes below are no longer relevant.

There are some resulting issues which affect Map Channels created from a My Map source. I will update the code in the next few weeks to try to fix some of the marker display problems.

Backed up copies of feeds are available on the server. If your map is not likely to change in the near future and you would like to revert back to your old markers please contact me and I will restore your previous KML feed. Please supply your user ID and map ID with the request.

If you upgrade all your classic Google My Maps to the new My Maps you no longer have access to the classic interface and KML links. One suggested alternative to upgrading is to create a new empty My Map and then to use the import function. Import the KML data from the old My Map to the new My Map. This lets you keep the old map as a backup data source.

Google's New My Maps : Don't Upgrade Your Maps Just Yet

Google announced recently that the maps created using Maps Engine have been renamed New My Maps. The previous version of My Maps are now referred to as Classic My Maps. View more details about these changes here.

The Google Lat Long article includes this line :
"today you can upgrade all your content to the new My Maps, and enjoy these new options."

Warning: It is recommended to NOT upgrade your existing maps.

The reason for this is that the KML feeds available through the new My Maps do not contain the style information that the classic My Maps contain. The result is that if you import the KML into Map Channels or any other external tool the markers displayed are all the same plain white markers.

Classic Maps are still available at Click on the 'My Places' link then click on the link labelled 'Or create with classic My Maps'.

You can continue to use both New and Classic My Maps, they is currently no requirement to upgrade all your maps. There is also no option to reverse the upgrade.

You can import KML data into classic My Maps. If necessary you can create a classic My Map and import the KML data from your 'new' My Map. To get the KML feed for a new My Map use this URL format: + the MID value for the my map.
(The map must be publically listed to get the KML).

Hopefully the style information will be added into the KML generated by the New My Maps. Also a KML permalink visible to the map creator would be a useful addition. News will be posted here if improvements are made.

Google Maps Developer Commentary

It appears that these latest changes are a continuation of reduced support for independent developers by Google.

The new Google Maps were launched in May 2013 but there is still no full developer API, just the basic Embed API. There is no official announcement of a full API for the new Google Maps, see link. The current Version 3 Maps API was released in May 2009.

Although the v3 API is functional there are still a large number of unfixed bugs. When v3 API changes do occur they are often the removal of a feature rather than adding anything new, e.g. Removal of the Panoramio and Weather Layers. Google Earth is another area where there has been no support added for the v3 API although this was available in the v2 API.

As a result of the lack of support many other maps developers have now moved on to other mapping APIs. One of the main reasons I have stayed with Google Maps is for the Street View functionality which is not available with any other API. Having said that the v3 street view functionality is not nearly as good as it was in the old v2 API. There is also a major street view bug which I reported to Google over a year ago which remains unfixed (please star this issue when you visit the page).

Despite these issues Map Channels will continue to work with the Google Maps API and hope that Google developer support improves over time. I will also be exploring other mapping APIs to offer a broad choice of mapping tools.

Working With Fusion Maps

We have recently been working with the website to create a map showing locations of bridges in their database.

The beta map for this project can be viewed at and at

This map makes use of regional polygons to help with navigation and filtering the map data. There are are 2 levels of regional polygons: states and counties. Clicking a state polygon will display county polygons for that state. The project includes a number of other new features and can be developed further.

Please Contact Us if you need a similar project developing or if you can help with the development and marketing of any Map Channels project.

Map Channels v4.10

The Map Channels v4.10 update is complete now and includes a number of major new features. View a full change log on the v4 About Page.

Below is an example map which uses v4.10 provided by London For Free - the guide to free things to see and do in London. The site lists free events, walks, day trips and budget accommodation tips.

This map demonstrates some of the new v4.10 features such as styled map types, the geolocation button and the new info panel option.

The styled map types are provided by the shared repository at Snazzy Maps. The map below uses the Retro style.

Use Map Channels v4 to map KML, GeoRSS or Spreadsheet data feeds. Alternatively you can create an edit-enabled map which users can contribute to.
