I have a Google map developed from Google map API.I have 12 areas in DB (eg: 1, 2…).I want to partition map with this Areas. Is it possible.?
If you have the coordinates of the intersecting points, you can draw polylines on the map.

There are logs where it is indicated: board number, time, date, latitude and longitude. information about their movement is constantly updated and new boards appear. how to display their movement on the map?
To display markers on a map, you can perhaps use Leafletjs for Javascript.
It is useful library that allows you to use a large array of mapping basemaps, and plot overlays on it, such as adding markers based on latitude or longitude, or drawing polygons or shapes. You can also overlay multiple maps, and there is a lot of functionality linked to the elements.
See their tutorials to get started or reference the documentation to see how you can manipulate the markers on a map.
Default clusters for baidu map are changing when the number of markers clustering together changes but in the google map you can set it to have different colours outside of a specific zone for example having grey colour for clusters outside of a city. How can I do the same for baidu maps?
I have parsed the co-ordinates of a polyline that I drew and exported using Google Maps. I also drew some markers on that same polyline (may not be exactly on the same polyline) whose co-ordinates also I have parsed and stored.
How can I draw a new polyline that starts from a co-ordinate of the marker in the old polyline to another on the basis of the old polyline?
I tried matching the co-ordinate of the marker with co-ordinates of the polyline to get the start and end point of the new polyline, but the co-ordinate of the marker isn't present in the polyline in most of the cases.

Store your markers - or polyline points - in an array and then create your polyline from that array. Hope this helps.
If I search 'province of huelva, ES' in Google Maps web page, I get a marker and the province boundaries with a color layer, that even is filled when zoom out.
It is possible to use Google Maps API for getting that polygon (or layer, json object, ...) and even change its color just providing a query string like in the Google Maps web page?
For now I must use regions LatLng values for drawing a polygon, but would be great if I can get the polygon only providing a search string.
Thank you guys!
Is there a way to create geo location search of closest points with javascript?
for example, we have a list of points with their coordinates. I need to find points ~ in 5km radius.
You want the harvesine-formula for Javascript and Google Maps.
You can use google geolocation API or Google map API
