coordinates

I have limited experience programming Android apps and none at all for iOS. Part of a future project of mine is to make my app be able to record the current location using GPS possibly on both Android and iOS. Can the GPS coordinates be taken in "Universal Transverse Mercator" format like in Google Earth for both platforms? If not, is there some way to calculate the coordinates to this format? EDIT: Any chance anyone would know what format the functions in their respective APIs return? The API will provide a location object (class Location for Android and CLLocation for iOS). Both API have

Given a list of tuples containing coordinates, I want to find which coordinate is the closest to a coordinate I give in input: cooList = [(11.6702634, 72.313323), (31.67342698, 78.465323)] coordinate = (11.6702698, 78.113323) takenearest(myList, myNumber) ... (11.6702634, 72.313323) Please let me know... For your data cooList = [(11.6702634, 72.313323), (31.67342698, 78.465323)] coordinate = (11.6702698, 78.113323) the shortest Pythonic answer is: nearest = min(cooList, key=lambda x: distance(x, coordinate)) with a function distance(a, b) returning the distance between the points a and b as a

For an Android application, I need to get magnetic field measurements across the axis of global (world's) coordinate system. Here is how I'm going (guessing) to implement this. Please, correct me if necessary. Also, please, note that the question is about algorithmic part of the task, and not about Android APIs for sensors - I have an experience with the latter. First step is to obtain TYPE_MAGNETIC_FIELD sensor data ( M ) and TYPE_ACCELEROMETER sensor data ( G ). The second is supposed to be used according to Android's documentation, but I'm not sure if it shouldn't be TYPE_GRAVITY instead

By looking at this image I think you will understand my problem pretty well: (image removed - url no longer valid, returns advertising now) So basically I want a function that takes an object as parameter and gives this object the correct coordinates based on how many objects I've added before. Let's say I would add all these objects to an array: objectArray[] Each time I add a new object: objectArray.add(object) The object.x and object.y coordinates will be set based on some algorithm: object.x = ? object.y = ? (I'm working in Java) Thanks for any help. Here's the closed-form solution that

I'm writing an Add-In to Visio 2010 in Studio 2010 on C#. I need to read a diagram currently opened in Visio. I know how to read shapes of the diagram. The question is if I have a shape object, which properties can give me coordinates of the shape on the page and other shapes (if any), the current one is connected with, if I have a connector object, which properties can give me shapes it connects and direction of the connection. Connections in Visio are handled through Connect objects. Each shape has a collection of incoming connect objects and outgoing connect objects. Their names are

I would like to ask for help regarding barycentric coordinates of a tetrahedron: Following an approach I found here: http://www.cdsimpson.net/2014/10/barycentric-coordinates.html i implemented a C++ function for finding barycentric coordinates of a point in a tetrahedron: float ScTP(const Vec &a, const Vec &b, const Vec &c) { // computes scalar triple product return Dot(a, Cross(b, c)); } Vec4f bary_tet(Vec3f a, Vec3f b, Vec3f c, Vec3f d, Vec3f p) { float va, vb, vc, vd, v; Vec3f vap = p - a; Vec3f vbp = p - b; Vec3f vcp = p - c; Vec3f vdp = p - d; Vec3f vab = b - a; Vec3f vac = c - a; Vec3f

I am in the process of learning iOS 8 app development with Swift. I have followed a tutorial on Treehouse that walks you through building a weather app in Swift and iOS 8. As an improvement to the app, the author/tutor suggests using CLLocationManager to get the location of the device to feed into the weather API instead of the hard coded latitude and longitude values. So having read various tutorial online, I have gone ahead and attempted to implement this suggested improvement. I have placed the code responsible for getting the location coordinates inside the AppDelegate.swift file.
