I just want some hint of how can I create an app in iOS which can do following.
When a user is at point X, user will click on start button so app will start a timer and track the movement. User will be on a horse and user needs to ride in a full circle. When user comes back to point X the app should draw the route taken by the user on the horse.
Aim is to ride completely in a circle. I want to make this app to
practice and see how close to a circle I ride.
I tried to look at GPS locator but I am not sure whether it will give me efficient results because the circle I ride can be as small as 60m or less in radius.
I don't know if iOS GPS can be this accurate. I read article on motion sensor and how to track rotation and acceleration.
But I am not quite sure how to use that to my advantage.
I just need some tips like which API to use etc.
Using the Standard Positioning Service one can achieve 15 meter
horizontal accuracy 95% of the time. This means that 95% of the time,
the coordinates you read from your GPS receiver display will be within
15 meters of your true position on the earth.

For integrate Map and draw path using current position google map is good option for integrate in iOS mobile .
small and range and get accurate result use indoor position system.

Is it possible to detect user movement via gyroscope? In general I need to calculate user's movement without GPS. I don't need to know user coordinates just something like this - 100 meters straight, turn left, 50 meters straight ect.
A gyroscrope measures changes in spatial orientation. Thus it can't tell you how far the user travelled. It can't even tell you if the user has turned right, since if the user also rotates the device left, you'll learn nothing.
I downloaded the Indoor Atlas iPhone SDK and also generated path maps and test paths for my venue. SDK navigates me perfectly when I am moving from one place to another but when I stop moving it generates scattered output with the position radius from 10 to 25. I am expecting precise co-ordinates in both the above cases in my project.
Is there any way to get more precision?
IndoorAtlas technology is using the history of magnetic field observations for computing the precise location. This means that the device needs to move some distance in order to collect enough data to converge to a correct location estimate, i.e., to have a location fix. We are constantly improving our service to decrease the time needed for the first location fix.
If you experience your position moving after you've already stopped walking yourself, please contact support#indooratlas.com with details of your application and venue where this is experienced and we'll look into it. Thanks!
I am trying to find a way to create several polygon geofences with iOS. I need to draw multiple zones in a city to represent areas, streets, etc. From what I've read so far, iOS only allows circular zone from a geolocated device.
Is it feasible with iOS?
Is there a web app somewhere to draw polygons on a map and generate the coordinates in an array?
1) iOS only allows to create circular geofences indeed however what you are trying to achieve is possible with some extra logic.
I have developed similar features so I suggest you to do the following:
create a circular geofence that embeds your polygon
when the device gets notified as being within the circular geofence,
start the GPS
every time you get a location update, check if its coordinates are
within the polygon
turn off the GPS as soon as the device's location is found within the
polygon, unless you need to be notified when exiting the polygon as
well
turn off the GPS when the device gets notified as outside the
circular geofence
As you need polygon geofences I guess you expect a good level of accuracy, so you would need to use an extra layer of GPS on top of the geofencing anyways, as geofencing is not accurate at all.
2) Have a look at those links:

I have a requirement mentioned below:
Already have a floor plan map image
First detect current location on floor
Then select the destination location using floor plan map image
Now application should provide direction & distance for that source to destination path
This is like how google direction works, but its in-house map require.
For example,
- Current position of user is: At his desk
- Where is Meeting Room #11
- So application should provide direction and distance updates on the map/floor plan image.
Any kind of suggestions/help would be great.
Thanks in advance
Couple of points...
You could create various audio files and play them as way points based on routing. Same principal as 'turn right at the next light'.
Definitely want to set your accuracy to: kCLLocationAccuracyBest. But this will still probably only get you accuracy of around +/- 10 meters at best.
Do a floor plan overlay using MapOverlayView.
If you are indoor, iPhone uses cell towers or WIFI for a location fix. This might be a problem for you because if you are looking to map multiple floors, only GPS can give you altitude readings - ground floor, second floor, etc...
I don't want to pour cold water on your idea but I have not heard of anyone successfully doing an indoor navigation app on an iPhone using standard stuff. If you really wanted to move forward on this project, your best accuracy might be using indoor bluetooth transmitters as navigational beacons...?
What you want is path-planing in the map, is that? If so, there is lot of algoritms you can use. You can choose a block size based on your map and resolution needs, divide de map into this, amd mark each block as navegable or not. Then getting from the first block trying in the direction of the destionation block, check if the neighboor block is blocked or not, and get going, until you reach (or not, if its not reacheable) the destination block.
Thats a pseudo-implementation, you have some option to do it, if I understand your needs.
(I dont know your hardware as said by others, with simple GPS and indoor navigation, assuming a 15m resolution is a good balance between optimistic/pesimistc signal, If its for robot-navigation, its not a goos approach in the GPS terms, but the algorimt is).
i'm trying to develop a small application that is able to track the position of the user indoors. I also want to create a small map of the building floor, so the user can see a image of it and his/her current position as they travel though the building. They would be able to connect via wifi.
Are there any tutorials/examples of how to create a navigational map indoors on the iphone? furthermore is it possible to accuratly track the position of the player by the use of wifi indoors?
Your second question is IMHO much more crucial, and the answer is "not very easily, and not very accurately". You'd have to see multiple APs (4+) located at well known positions at the same time, and triangulate your position from the signal strengths. This would also require that the phone scans for networks all the time but doesn't connect to any.
