How do i get nearest coastal point in google map. I have read in google Places API that we can query for geographical locations.
Any help??
Take a look at the Google Elevation API
https://developers.google.com/maps/documentation/elevation/
You can do request for any location on the map. You can possibly tweak this API to find the nearest 0m elevation from a custom location.

Using HERE Maps Api, for a geographic coordinate (lat, lng), I would like to find address information for the nearest routable road. Information that includes:
Address (street, house number, city, postal code, country)
Bearing/Heading of the road (0 to 360 degrees from True North)
How can I achieve this through HERE Maps API?
So far, this is what I have been able to achieve:
Calling the calculate Route API with identical start and end endpoints and mode=car will force the API to snap to the nearest routable point. This step is necessary for when the input coordinates are for a pedestrian street.
Using the nearest routable point coordinates, I can call reverse GeoCode API and I will be able to find the address information I need.
The next step is where I'm currently stuck. I'm able to find information like direction=NW, however I can't find the ~exact bearing in grad, for example bearing=265.
Is this achievable? Are 3 steps really necessary or is there a HERE Maps API endpoint that can provide all of this?
You can use the Fleet Telematics API to get the headings value for a particular road. Read more about the api here - https://developer.here.com/documentation/platform-data/topics/quick-start-view-map-data.html
You can also look at the field explanationshere - https://tcs.ext.here.com/pde/layer?region=WEU&release=19111&url_root=pde.api.here.com&layer=ADAS_ATTRIB_FC1
HEADINGS Horizontal road heading [10^-3 degree] at coordinate points along the link, when driving from Reference Node. Comma separated. Each value is relative to the previous. No values here for the ref/nonref nodes, because they are in the separate fields REFNODE_LINKCURVHEADS and NREFNODE_LINKCURVHEADS.
I'm trying to figure if there is a way to ask the Google Map Api to know if a random gps coordinates like :
48,277373
2,4883883
Is accessible by pedestrian ?
It should be possible because if I ask Google Map to lead me in the middle of a river, it will lead me just on the nearest point before the water.
But I'm not sure how about I can get this information by providing the coordinates.
Thanks for your help :-)
I'm using google map direction API in our application. Map with directions working well with traveling modes like Driving,Walking,Transit and Bicycling. But it not showing flight directions when we enter two cities from different countries. So for showing flight directions what should i do? Please help.
There is no FLIGHT TravelMode in the Google Maps Javascript API v3.
google.maps.TravelMode constants
The valid travel modes that can be specified in a DirectionsRequest as well as the travel modes returned in a DirectionsStep.
BICYCLING Specifies a bicycling directions request.
DRIVING Specifies a driving directions request.
TRANSIT Specifies a transit directions request.
WALKING Specifies a walking directions request.
One option would be to draw a normal or geodesic Polyline between the two airports.
I am working on a project that requires I plot markers at metropolitan coordinates via the Google Maps API. I can plot the markers just fine and draw polygons easily, but I need to draw polygons parallel to the road common to each coordinate and if possible, find traffic direction. Each coordinate input is verified to be next to a road in a a downtown metropolitan area. Is it possible to get that information from the Google Maps API or open streets API?
A sample coordinate is [47.6018, -122.314].
There are multiple online routers based on OpenStreetMap data availabe. Several of them offer a GPX export. Try for example OSRM or graphhopper.
I am working with a security company that has a patrol car travel around a neighborhood. Every 30 seconds, they record a GPS coordinate/point which I can download and use. I'm trying to map a 'path of travel' for the patrol vehicle using Google Maps API.
I understand how to map (marker) all the points using the Google Maps v3 API. I also understand how I can do a driving route between a few points using directionsService. According to Google and StackOverflow, the maximum number of waypoints is 26.
The problem is that I have dozens of these points (1 hour = 120 points). I can't just draw a polyline between the points because I need it to show the path of travel on the actual street - not as the crow flies between 2 points. Also, I don't have 10K to purchase an Enterprise license.
Any ideas on how this might be accomplished or am I SOL? Can you draw 120 multiple 'routes' on the same map? Speed is not important here.
Thanks,
Mike
Can you draw 120 multiple 'routes' on the same map?
You can. When you want to draw the routes by using the DirectionsRenderer you must use a separate DirectionsRenderer-instance for each route.
Another approach: request the routes via the DirectionsService, but use a custom Polyline to draw the route. Each time you get a new route you'll only have to push the points of the new route to the path of the polyline.
