How do I subdivide a polygon into equal areas using google earth engine, then export these sub-polygons as shapefiles to a folder?
I still have no idea on how to go about it. Kindly assist.

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 have classified (supervised classification) sentinel-2 optical imagery using google earth engine java-script api. In one project i have also used python api of Google earth engine for calculation indices NDVI, EVI etc. Now i want to use the same(google earth engine python api) for image classification. But i am unable to figure out how i can provide training sets for classification from earth engine python api. Is it possible to save the training points in fusion table and use that for training in python api for GEE? or is there any other way to do the same.
Advance thanks for your assistence.
You can export to KML (Export.table.toDrive()), then upload to Fusion Table or export to Earth Engine asset (Export.table.toAsset()) and read it directly from there.
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.
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.
Is there any alternate free application like Google Earth Pro ? , My main thing is it should import shape files as a layer in the map.
Depends upon what you are looking for. If you really just want to see the shapefile, use something like qgis or udig.
If you want to see the shapefile on top of a street map or a satellite base layer, I am not sure there is something that will work for you out of the box. Open Street Map has the data; a service like http://www.osm974.re/osm2gis/ can export a limited area of Open Street Map data as a shapefile.
You might want to peruse this page from the Open Street Map wiki: http://wiki.openstreetmap.org/wiki/Shapefiles
There's this open source application called "Marble" that works ok...but unfortunately you can't load shapefiles into it. You have to convert your shapefiles into wkt with qgis or something before loading them in. The satellite imagery is so pathetic as to be considered nonexistent. But its faster than Google Earth Pro that's for sure, and you can use OpenStreetMap to get a pretty good vector scaled experience to see where you are.
