I suspect this is not the correct place to be asking this. However, I
just started messing with "My Maps" and the API yesterday and I'm
still a bit confused as to what is what.
My goal is to create a series of "My Maps" showing highlighted block
ranges. Thus far, I have done a couple by hand. Example:
http://maps.google.com/maps/ms?ie=UTF8&hl=en&msa=0&msid=2152322357122...
However, it occurred to me that the process could be largely automated
by passing the begin and end block range addresses to Google geocoder
and using the resulting coordinates to generate a series of line
markers, write this to a KML file and then be import it into a My Map.
So far, I've hacked out some rough PHP code that will retrieve
coordinates from the Google geocoder using supplied addresses as well
as some PHP that will generate appropriate KML for lines between two
coordinates.
The brick wall I'm hitting is that I'm now realizing that to have a
line follow the streets, the coordinates for each curve/turn have to
be acquired and separate line markers written to the KML file.
The Google Directions API does this, except that it also spits out way
more data that I need; waypoints, turn directions, etc...
But that is what you need. The directions from one end of the block
to the other and the associated polyline. You can ignore the other
information (waypoints, turn directions, etc...), but you do need to
display it on a map to comply with the terms of use.

I had considered using the Directions API and just extracting out the
polyline coordinates. Though, for me, right now, this is sort of a quick
and dirty hack. It took me about 30 or 40 minutes to do that map by
hand, drawing the lines using the My Maps interface. I have about 14 of
them I'd like to do with roughly the same number of block ranges to
highlight. If I could hack out some code to automate the process down,
awesome.
There's a remote chance the company I work for may see this and want me
to do more. (These 14 are for my own use) In which case, I'd very much
want to automate it. However, what you say about the terms of use both
concerns and confuses me. You say that I can ignore the additional
information that I don't need from the API's response. Then you say it
must displayed on the resulting map else it's a violation of the terms.
I certainly want to make sure my methods are not in any violation in the
event I am asked to replicate this method for others to use.
