I have a BlackBerry app in which I want to load the Google Maps app. I have the code for plotting a single location, and now I want to plot multiple locations on the same map.
When I search, I found that multiple locations can be plotted with a kml file having multiple location coordinates. But this kml file should be available in a public URL. So that is not possible. Is there any other way to pass multiple locations simultaneosly?
Is it possible on BlackBerry?
try blackberry maps demo (included in the blackberry simulator). it have the facility to show multiple locations.

I used this Xamarin.Forms Map tutorial to create a simple app that displays a map and plots several points (from our database). The app works as it should, and that would normally be enough.
But I wanted to make my app different, and I wanted to use another type of map. For example, Waze and Google Maps both show me how to get to my nearest Walmart, but I like Waze's map more.
So my question is: what exactly does Xamarin.Forms.Maps display? It's a control that shows a map, but why does it show a Google Map instead of, say, a MapBox?
And since Google Maps and Waze are owned by the same company, why wouldn't I be able to display the Waze map instead of the Google Map?
Finally, what other map control options do I have? My app simply takes several coordinates from a sql table and plot the points in the map.
I have a list of customer (GPS coordinates) for each salesman in excel file. I want to create a polygon in Google map that shows area of each salesman in map.
Is there any tool that shows my salesman area in the Google map ?
For the first step it is easier to use Google Earth.
To display data you need a google kml file.
Create a placemark, and use the Polygon.
More, see https://developers.google.com/kml/documentation/kml_tut
To display a kml in google maps, the file has to be located on a server reachable by an url.
Ffor goggle earth a local file on your disk is sufficient.
For this problem, you may want to use a concave hull algorithm. You can read more in depth at https://gis.stackexchange.com/questions/39205/converting-point-sets-to-polygon-boundaries
In JavaScript, you can use https://www.npmjs.com/package/concaveman.
Is it possible to map data by census tract on Google Maps? Specifically, it would be good to know if this capability exists within Qlikview's Google Maps extension, but it would also help to know if this is something that can be done at all, and if so how.
Yes, it appears so.
Census tract data is available via a KML file:
https://www.census.gov/geographies/mapping-files/time-series/geo/kml-cartographic-boundary-files.html
As part of a larger set of Census related data this is available in KML:
https://www.census.gov/geographies/mapping-files.html
The following are directions from Google on how to use KML files with their products:

I have a saved google map in 'My Places', with over 100+ pins added for locations around the UK. Is there any way I can avoid having to use the embed feature to display this map on a webpage, sort of calling the saved map by ID via the google API?
Essentially what I want to do is get access to google's new visual refresh and be able to control the settings of the map more with API.
The map link is this: https://maps.google.co.uk/maps/ms?msid=207590858966548688521.0004aa52150024d3431b2&msa=0
Can we parse anything here...?
You can overlay the KML output by MyMaps using a KmlLayer in the Google Maps API also:
your MyMaps data displayed on an API based map
Updates in MyMaps will (eventually) be reflected on the map.
Using https://mapsengine.google.com I was able to import the maps data and utilise the pins that way. Not ideal, but still some better functionality.
I'm trying to develop a mobile app that locates the nearest location. I'm using Phonegap, Google Maps API v3, and KML layers to show the locations. I came up with this workflow:
1. The main view contains an autocomplete search box , so that once the user starts a search:
The query is sent to a service that will filter and generate a KML file for the results.
So here I am not using Google Maps Distance API; the service will retrieve the user's lat and long and then generate KML files which will contain the user's location and sorted matching results.
Finally we use the KML file with Google Maps for rendering the results.
Is this the right way to go about doing things?
Or is the Google Maps Distance API more accurate than manually calculate the distance using some maths?
Thank u in advance.
