iphone - How to add a heat map to a google map - objective-c

Im looking for an SDK that provides the tools to draw a heat map over a google map given a set of points with values.
I've seen Locomatix, but we prefer a site that doesnt require an API key to use the service.
Do you know any?

How to integrate Google My Maps with API key?

I have spent the past few months creating a custom map on google My Map. I'd like to now plug it to an API key to put it on my website as my website builder wont allow me to embed like you would probably do normally.
I don't really understand API keys no matter how much I research them but in summary - Is it possible to import a Google My Map to be a associated with an API key so I can put the API key on my website to enable an interactive map?
I thought by signing up to get an API key I would be able to import my google my map to the maps platform map manager and therefore associate it with my API key, import the key to website and have an interactive map. From looking on the map manager on the maps platform, it will only allow you to choose one location or start a map from scratch and doesn't allow you to import spreadsheet data - unlike with google my maps.
Can't find any answers anywhere so any help would be greatly appreciated
Thanks in advance

Elevation API/database without using Google?

I need to find the maximum elevation along a given path (defined by start and end latitude/longitude), but in searching the internet the only option I seem to find is the Google elevation api. Unfortunately, that's not an option because the google terms of service explicitly state that:
The Google Maps Elevation API may only be used in conjunction with displaying results on a Google map. It is prohibited to use Google Maps Elevation API data without displaying a Google map.
Since my usage does not involve a google map (I'm using Open streetmap data combined with FAA sectional charts), using the Google Maps Elevation API would directly violate this. Additionally, I want to say that Google prohibits commercial usage, which this is (although we may be able to pay an exorbitant fee to get around that restriction).
In any case, given that the Google Maps Elevation API isn't an option, what other options do I have, either in a web-based API similar to Google, or in some sort of a local database download that I can query?
The USGS offers downloads of elevation data in various formats at https://nationalmap.gov/small_scale/atlasftp.html I was able to download a GeoTIFF of the area of interest, load it into a PostgreSQL database, and use the PostGIS extension to perform queries against the data to retrieve the desired information. No licensing issues or number of data point restrictions, plus it's all local.

Get address by location

I'm using Bing Maps on Windows store app (XAML).
I have the longitude and the latitude and I want to get the address (if it exists) of the location.
How can I do it?
Thanks!
You want to do what is called reverse geocoding. Take a look at the SearchManager class: http://msdn.microsoft.com/en-us/library/dn306041.aspx This will let you reverse geocode your coordinates and get the address.
Alternatively you can also use the Bing Maps REST services:
This would be more work than using the search manager, but wouldn't require loading an interactive map first.

Since it sounds like you are new to using Bing Maps in Windows Store apps I'd recommend downloading a free copy of my eBook on creating location intelligent Windows Store apps. It shows how to do this an a lot more. You can get a copy of it here: http://rbrundritt.wordpress.com/my-book/

Apple/Google Maps SDK for getting directions data

I am trying to build an iOS application that will basically give me distance and route to how to go from my current location to a specified destination.
Does Google Maps SDK or Apple Maps SDK expose such an API to get directions/navigation data without leaving the app?
I know Google Maps API has directions data REST API, however I was looking for more integrated solution that utilizes MapKit directly, if any. Thanks for reading so far.
As far as I know, Apple is not supporting GoogleMaps in MapKit. I used GoogleMaps, and I need to import all libraries and add the functionality by code.
But it supports Apple Maps.

Can the Google Map API be used with an external map file ?

If the detail level of the area I want to display in my application is not good enough (like large private properties such has harbours or airports), can I replace the original Google Map with own data ? Using with Google Map enterprise/business version.
Thanks

You want a custom map type, that uses your tiles when the zoom is greater than that supported by Google Maps tiles natively.
