Google Map Maker Directions - New!

Google Map Maker Directions - New!

Last week, Google switched on the MapMaker Tiles for API developers. See previous post (12th Feb '09).

MapMaker is based on user generated content.

"With Google Map Maker, you can become a citizen cartographer and help improve the quality of maps and local information in your region. You are invited to map the world with us!"

Now those tiles have graduated to Google Maps. 31 countries (of 160+) have made it so far - though this is likely to expand through the year and beyond.

The Full List is available

But wait there is more...

Driving Directions in MapMaker New!
(but use with caution)
Google Map Maker Directions - New
Directions in a simpler form have been enabled, usually only the likes of TeleAtlas navigation is used on Google maps but now user contributed content is being used for the first time available in Map Maker Mode only at present [google login required].

Some of the countries do not have the simplified driving directions available.

Here is a working example
http://www.google.com/mapmaker?hl=en&ctype=0&saddr=Quetta&daddr=Zhob&dirflg=&gw=56&ll=30.192618,68.895264&spn=4.756322,7.426758&z=7
but don't expect this to be the shortest route.

Here is a better example
http://www.google.com/mapmaker?hl=en&ctype=0&saddr=Colombo&daddr=Mullaitvu&dirflg=&gw=56&ll=8.070086,80.330403&spn=2.724552,3.713379&z=8

Google Map Maker Tiles come to the API

Google Map Maker Tiles come to the API

Update:
One of the best areas of difference is in Sri Lanka
Here is the differences in Colombo


Google Maps Normal Tiles limited in content.
This shows the power of user contributed content.

http://mapperz.googlepages.com/mapmaker_api_sri_lanka.html
(Warning this example is in the latest *experimental* version of the api v146b and GLog is always displayed)

Google Map Maker gives users the power to add, edit and amend data in Google Maps.
This has been running for awhile, but as yet it has not been used by Google in the Main Google Maps Site.

A first. The Google Maps API has had the option of (G_MAPMAKER_NORMAL_MAP);
for a while but this has not been enabled, until today.Normal Google Map Tiles
Here is one Country in Google Maps with very little data coverage. Iceland.

But now with the API you can switch on the User Made Tiles from Google Map Maker.

Google Map Maker Tiles - Available
Not much more detail , but it is better than the normal tiles from Google Maps.
Note:Copyright is Google only. (Coastline TeleAtlas still?)

There are a number of Countries and this is one example, so check the list and see if the country your are interested has more content than the original Google Map Tiles.

You can view the example here:

Mapperz would like to thank Mike Williams for the tip off .

Where is the GPX Path?

Where is the GPX Path?

(well the answer is on the map now thanks to Bill Chadwick's update of GPX import.)

South West Coastal Path - Lizard Point (Cornwall)
Importing of GPX data is very fast and when in 3D (Earth) Mode it shows you the terrain your likely to encounter. (weather not included!)

"GPX to GeoJson Converter is purely a convenience for those who want to read a random GPX url on a page from a host that lacks server side scripting"

Example - The South Coastal Path
http://tinyurl.com/5zd4af

NOTE* The most annoying issue for this site is not the author's fault at all. It's the Ordnance Survey with ridiculously low openspace tile quota (currently 30,000 per 24hrs).
This is a very popular site and 30,000 tile impressions needs to be 75,000 at least.
Why does the Ordnance Survey insist of bottlenecking useful web mapping applications?
And why allow users to have 1:50,00 colour rasters (Landranger Maps) and StreetView 1:10,000 and not the very useful 1:25,000 (Explorer Maps)?

Data for the South West Coastal Path is available from (GPX format for GPS)
http://www.southwestcoastpath.com/main/useful_info/GPS-downloads.cfm
