It looks like you just want to use different kinds of markers on a map and filter them. There're some similar examples (taken from the gallery): http://map.calvertfoundation.org/#2/8.00/-32.00/nokia-day/stories http://guia-das-cidades-da-copa.g1.globo.com/bahia/turismo-e-viagem/pt/como-chegar/arena-fonte-nova/ And here're some related tutorials on how to ...

You can't Google: From February 2015, maps created in the classic Google Maps — https://maps.google.com/ — will no longer load KML/KMZ files from external websites. However, we know that KML files are a really useful way to work with geographic data, so we’ve added KML to Google My Maps, and continue to support this format with other Google Maps APIs. ...

One thing that's wrong is your first and last coordinates need to be the same for a polygon. I'd get rid of your first two points (since lat and long are reversed). I pasted a fixed version for you here jsbin.com fixed json

You can use marker-animate-unobtrusive library to make markers smoothly transition from one location to another. You could initialize your marker like that: var marker = new SlidingMarker({ //your original marker options //... }); So your marker will animate from starting location to given one on this call: marker.setPosition(givenPosition); ...

I think you can use the google.maps.geometry.spherical.computeHeading method. See documentation here: https://developers.google.com/maps/documentation/javascript/geometry#Navigation

For drawing the polygons, use Leaflet Draw. Also, check out the turf.within function. It takes a set of points and a set of polygons and returns the points that fall within the polygons. For the excel piece, there are several ways to hack this. The easiest would probably be to setup a simple server endpoint that runs ogr2ogr on your geojson and outputs a ...

Have you looked at gogeo Platform (www.gogeo.io) or CartoDb (http://cartodb.com)? I guess that Google Maps can't handle with millions of polygons. goGeo was made to work with Geospatial Big Data and CartoDb was built upon Postgis.

What you are looking for is a way to represent binary geometry as a string so you can easily pass it to the map. See PostGIS geometry outputs section of the docs. You might want to look into GeoJSON a bit.

I came across this issue during january. I solved it with the logic "if drawing mode is already null, then don't try to set it to null again". google.maps.event.addListener(drawingManager, 'polygoncomplete', function (polygon) { if (drawingManager.getDrawingMode() === null) { return; } else { ... do your stuff ... } }); Usually ...

There is no way you can get the map that small and still be readable like at that zoomlevel. Just consider this: the scalebar on gmaps (bottom right corner) is roughly 1", so even at z14: 1 km = 1 inch an imaginary country with 1000km*1000km, so a map of that country would take 1000"x1000" (1000000) you want it colored, so at least 8bit, i.e. *8 you want ...

I managed once to remove a crossing connecting two railway segments. All other times I get this error message too. I even checked all properties of the two segments t be the same as far as shown. I guess this is an internal bug in the google map maker. Removing crossings that connect two segments that have (nearly) the same properties should IMHO even get ...
