My requirement is, I have a set up of few IP cameras in a certain area. I have geo-location of each camera.All cameras are set-up in urban area. can I call these cameras on google-maps? is there any API for that ? i should get live feed, when I click on a particular camera .. Please help me
Google map not providing any API for controlling any type of hardware devices. If you want to control you have to set up everything yourself. Google map is an API for doing map or location operations like getting the latitude and longitude of a location, get the distance from one location to another, and a map view. In your case I don't think Google map can give any help.
You can start reading documentation of Google map from here

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 Google premium account.
I am using google map javascript api for showing map on our website.
Feature of map like
Load the map
Place the markers programmatically with coordinates.coordinates already stored in database. i used those coordinates to place the markers.
so my question is that what is the limitations for above features for premium account? Is there any limit that how may times we can load the map and place the marker.
I have seen some requests limit for directions and other things. but i am not using direction feature.
Thanks!!!
When you use a Premium plan Google Maps JavaScript API map loads will be counted against the purchased map credits. Map load is incurred when you show a map in your application. Interactions like zoom, pan or create new marker are not counted.
There is no daily limit, you can use maps while your map credits are not exhausted.
Client side services (geocoding, directions, distance matrix) and places library will consume your map credits as well.
For more details I can suggest reading the documentation:

Would it be possible make Google maps aware of our beacons via their registry or api or something, so that google map can accurately give indoor direction to users in a facility that is under our control(where we can deploy beacons)?
Example: In a mall we own, can we place beacons and submit them to Google Maps so it can give better results?
Some links I found, but can't figure out an answer:
https://developers.google.com/beacons/
https://developers.google.com/beacons/proximity/guides
https://www.google.co.in/maps/about/partners/indoormaps/
https://play.google.com/store/apps/details?id=com.google.android.apps.insight.surveyor
Google used to develop this beacon-based location service call Google Here but it was scrapped due to the reasons of privacy, but then you can do the following to get your beacons locationing up.
Let say you have multiple beacons in one mall.To make this explanation simple, just treat the indoor maps and normal maps as the same thing, and those beacons you going to add are like the places in the Google Maps.
First of all you need to make your building floor plan available on the Google Maps. You can do so by using the following steps to submit your beacons location with the floor maps of the building, so that your beacons location can be automatically align with your stores/building.
https://support.google.com/maps/answer/2803784?co=GENIE.Platform%3DDesktop&hl=en
After your floor plans appear on Google Maps, you can submit your beacons location using the Map Marker tool (Retired March 2017, moved to Google Maps after that).
You can then use the Google Maps API's Map Object to work with your indoor map, including getting location of all your beacons.
https://developers.google.com/maps/documentation/android-api/map#indoor_maps
The IndoorBuilding Object allows you to get the active level that you are accessing. You can use the function getLevels() to get all the levels in the building, and then use getActiveLevelIndex() to get active level you are working on.
After getting to the right floor, what is left is the interaction between Google Beacon API with the maps you created.
latLng and indoorLevel in the Proximity Beacon API would then return the exact location and detail level that your beacons located.
You can use this link to upload indoor map of a building.
https://maps.google.com/floorplans/find
Submit the details of floor and everything.
Hope it will help.
I believe there are no current plans to use registered beacons for directions indoors, or even for lat/long type location (more for semantic place inference), but I feel it is a very good FR so I went ahead and added it to the Android issue tracker:
Including support for BLE beacons in FusedLocationProvider.
Please star it to get updates.
As you can read in the other reply beacons can be used currently to improve indoor location accuracy for 3rd party apps, but it requires a lot of work by the developer and it is not supported by the Google Maps Mobile.
My question is how does google map or mobile GPS able to find mine current location ?
My high level understanding after reading this article is , GPS receiver gets the location coordinates through these satellites
and this location is further passed to Google Map(or any other client) API which then locates the exact location on map. Is it correct ?
Somewhere i also read that Mobile towers also plays the role. But my unserstanding is that this can be used to track the mobile location if required but mobile apps or Google maps
uses the satellite approach. Right ?
It's a bit inaccurate question to ask "How does google map location works", because Google Maps app (as well as any application leveraging google maps API) is just a consumer of location services on your device and is not used to determine the current location itself.
Because Google Maps is just an application, it can be run inside browser, or as native application. Depending on that, the way how it gets to your location information may also vary.
If you run the Google Maps from web browser (or WebView, or UIWebView,..) it usually uses HTML 5 geolocation API to determine your location and then use that to show your position on Google Maps. HTML5 geolocation then uses some lower level services to get your location, like GPS sensor, WIFI, network etc. There are already questions on how HTML 5 geolocation determines your position on SO, like this one or this one.
If your app is run as standalone application, it depends on your platform, your device sensors, your network,.. how the location is determined. So for example on Android with GPS sensor, LocationManager is used, which retrieves the location again using GPS, or from network provider, or returns last known location, etc. There's a lot of various interesting techniques behind this, which you can look up yourself (For example to determine your location using Wifi, Google has a database of WIFI SSIDs and their locations retrieved using anonymous device tracking and is able to roughly tell your location only from Wifi networks around you.)
I was wondering if anyone knew of any map APIs that offer topographical or relief data? I've had a quick look at Google and Bing APIs, but could find nothing there.
Google allow you to view a map as TERRAIN, which means you can see the topography of a map, but I want to be able to get at that data - i.e. if I were to draw a line between 2 points on Google Maps, I want to know how high above see level points along that line are.
Is this possible with any map APIs out there?
Thanks for your time!
Here's a simple example of height along a route.
I use USGS to obtain the elevation data, Google Maps API to plot the route and Google Charts to draw the elevation profile.
Full details in the associated tutorial.
Here are a few web services that provide elevation data:
USGS Elevation Query Web Service
EarthTools
GeoNames
