You can now use your desktop to create a biking or walking itinerary using Custom Maps in Google Maps. You can choose to share these directions by allowing people to view your Custom Map and avoid the hassle of scribbling them down or printing them out. Additionally, you can access these stored directions from your phone with the Google Maps Android application.
This provides a quick and easy way to navigate trips that have multiple routes and stops when you’re on-the-go. Give it a try the next time you plan a group bike ride or to keep track of your favorite jogging routes.
To start, first get directions to your destination(s) and select the biking or walking icon in Google Maps. Next, scroll down to the bottom of the directions in the left-hand panel and click the “Save to My Maps” link.
You can then save the directions to an existing custom map or create a new one. Once the directions have been added to a custom map, you can continue to insert extra stops or make notes. After you complete mapping out your itinerary, you can choose to share it with friends or a workout buddy.
If you have an Android-powered device, you can access stored directions in Custom Maps right from your mobile phone – just click on the layers icon in the upper toolbar and select the saved Custom Map you want.
If you don’t have an Android phone, you can open your Custom Maps using your phone’s browser and visiting maps.google.com.
Do you love to explore the outdoors with Google Maps but sometimes wish it had the details of a trail map or a tourist attractions map of a foreign city? Do you sometimes wish you could take one of those “You are here” maps with you to help you find places in an unfamiliar environment? Do you prefer maps on your phone rather than on paper?
If you answered “yes” to even some of these questions, you may want to take a closer look at a new Android app called Custom Maps — recently released as open source at code.google.com.

The Custom Maps app allows for easy creation of digital maps from any map image. The image can be a photo of a paper map, a photo of a brochure map, or a picture of the map posted at a trailhead or at the entrance to an amusement park. It could also be a .jpeg or .png image hosted on the internet or a screenshot of a PDF map. All you have to do is choose two (or more) matching points that are common to both the map image and Google Maps, and Custom Maps can show your GPS location on the map. This makes it an excellent mapping option in situations where data signal is not available like in state parks or abroad, or when alternate map images show details that are not included in Google Maps.

Custom Maps stores the geo aligned map images into KMZ files, which are simply ZIP files containing the geo location information in KML format, and the map image file. This makes it possible to take the map image out of the KMZ file, add some personal markup in the map using an image editor, and put the image back into the KMZ file. As long as the image is not resized in the process, the marked up map image can now display the user’s GPS location.
Custom Maps users can share created geo aligned map images as email attachments or by using QR codes. When a Custom Maps compatible QR code is scanned by a barcode scanner application, users can open the link directly in the Custom Maps app instead of a web browser.
- dealing with large images in constrained memory environment of mobile devices
- parsing XML (KML) documents using XML Pull API
- using the Google Maps Android API and displaying translucent overlays on MapView widget
- declaring an app as able to handle special URLs and file types so it can be launched by QR codes and so mail applications can direct attachments to it
- triggering file sharing intents from an app
But Custom Maps is not finished yet. Several new features are planned including distance measurement, marking map locations with icons, making it possible to geolocate map images without Google Maps or data connection, working around the app memory limit to load larger map images, and automatically switching between stored maps based on user’s location and zoom level.

to add these and more features to Custom Maps.
