My question is very simple and can be understood in one line :
Is there a way, tool, ... using google maps to get an overlay of all surface which is below a certain time of travel?
I hope (think) the question is clear, but I coulnd't find anything related on the web.
If you have any information, I'll take it !
Here is what I mean illustrated by an example :
I search for a new place to live. I know the precise adress of my office.
I would in this case be able to overlay on google maps the surface which is under a certain time of travel (let's say 30 minuts by car).
We would have a long surface colored around motorways (because you get faster), and colors around roads.
Is it clearer? :s .
A similar site with even more options is How Far Can I Travel. Here you can choose between inputting your speed of travel and a travel time OR a distance. Optionally, you can also specify how accurate you want the results to be.
Finally, for $8.75, you can buy the article Stata utilities for geocoding and generating travel time and travel distance information by Adam Ozimek and Daniel Miles that describes
traveltime, a command that uses Google Maps to provide spatial information for data.
The traveltime command takes latitude and longitude information and finds travel distances between points, as well as the time it would take to travel that distance by either driving, walking, or using public transportation.
