I am looking for a online app or code to embed that allows a user to set a certain location on a map.
What we need is a form in which a user inputs its name, address, email and his favorite location which can be a certain point in a town, a point of interest or an arbitrary place in the woods. We would like to see the map selection as well or the GPS coordinates of his selection.
We thought about Google Maps but did not figure a way to achieve this.
Do you have an idea how we can achieve this?
Thanks!
I found something that is usable:
Google Maps API Reverse Geocoding

I am developing an application in which when the I enters an address ,I fetch latitude and longitude of that address and drop the pin.
But what I want is like I enter any business or address then a list of that search comes in google maps and multiple pins are dropped for that address.
I also want this feature to get include in my app but when I pass my address only one location comes not a list like it comes in google maps.
Please help me if anybody knows how google maps searches a couple of locations for that address
ex:- caribou coffee, chapel hil
Any suggestion will be highly appreciated
Thanks in advance!
This functionnality is provided by Google Places API.
If you are looking for an algorithm it's using the harvesine forumula or a quadtree data structure. A quadtree or a r-tree in maps applications most likely it uses a space-filling-curve to sort the quadtree. If you look for sfc I recommend a hilbert curve because it has better space fill quality but normally they uses a z-curve.
I am working on an iPhone map application and wanted to know whether it was possible to request any labels visible on Google Maps given a longitude/latitude and radius?
For example if I gave the following location to this Google Maps API, I would get back McCullough Hall, Moore Hall, etc. The list would be any place labels visible on the map (doesn't have to be just restaurants, businesses).
If this is possible can you direct me to where I can learn more about this. If this isn't possible, can you direct me towards another API where it is possible?
Look into Googles reverse geocoding, I think that's what you're looking for.
The short answer, you cannot!.
The only way is to search for places by name and get a reference key to query the place details including lat/lng. Not the other way around.
IMHO, this is mainly a policy of Google instead of being technical limitation.
I need to use in my application the search functionality used in the Maps IPhone application.
The application user should be able to search locations by a commercial name and then to select one of the annotations (pins) proposed on the map.
Is this function available to use easily?
This functionality is not available in MKMapView
But i will give you a suggestion
Keep a TextField and accept the user search name from that. Then by using google API get the details about the searched location
http://maps.google.com/maps/geo?q=yourSearchName&output=xml
This will return all location information with latitude longitude, Parse those details.
I think Parsing will not be much complicated.
Use Annotations to pinpoint in the map with the latitude and longitude values you got from parsing.
when you go to maps.google.com and search for "cupcakes" for example, you get the results displayed on a map, and on the left there is a list of results.
I want the user of my application (iPhone and Web) to be able to enter a search term, then it searches on google and provides a list (much like the list on the left in maps.google.com), the user can then select a location from the list.
The list would need to be in XML format or something similar that can be parsed on the iPhone. It needs to include the Name of the location, a description (if provided) and its address/coordinates.
Is this possible, and if so, how can it be done?
You'll probably want to use the Google AJAX Search APIs, which has a different set of terms from the Geocoder. The Geocoder is for taking an address and returning a lat/long, not for things like local search. Specifically, you'll want to use local search feature. Check out the section on "Flash and other Non-Javascript Environments" for info on how to access this though a RESTful interface (for the iPhone).
Google provides a number of map services where you can search for locations, etc. Especially their Geocoding API may be of interest. If you use their services you are however required to show these results on Google Maps.
An alternative to Google is to use one of the free GeoNames services. They have a more relaxed set of conditions.
Is it possible to display nearby businesses in mapkit? If not, how else can that be done?
Is there a way to display by category - restaurant, retail, museums?
Also, I don't think displaying traffic flow is available. Can anyone confirm?
The current version of MapKit does not support such features.
It's main capabilities currently are:
a scrollable/zoomable map
reverse geocoding (get the address for some given lat/long coordinates)
add annotations (pins) at a given lat/long
show phone's current location
show Standard, Satellite, or Hybrid view
To display nearby businesses, you would have to:
query a third-party for that information which would ideally return lat/long coordinates
add annotations to the map using the returned coordinates
This is an interesting and emerging business idea!
I live in Nordic region and there is an open Mashups especially for sweden.
By open i mean, any one can request and get access to the content to find nearby Cafe / WiFi / Sushi restaurants etc..
BEGIN PLUG WARNING
Check my iphone application which fetches content from the mashups and display using MapKit!
END PLUG WARNING
And there is a commercial content provider called Info24 for nordic countries at the moment.
Like DyingCactus said, it's not currently possible without using your own calls to one of the mapping service providers. There are options available, though.
One of them is CloudMade. They have a good iPhone library and support almost all of your requirements.
Check out the API at Cloudmade.com
I know this thread is kind of old, but i figured out a free alternative to do what you are looking for, more or less. You just nee to tap into a maps.google.com service and get a kml or JSON output. I used KML (XML) becuase i found the filesize to be consistently smaller. I wrote a 3 part series on my blog about how to do this for anyone that is interested.
