coordinates

I am completely new to Python. Therefore don't get too mad at me, because I am sure that there are basic things that I am missing. Here is my problem: I am trying to extract mouse-click coordinates from an image and use those coordinates as variables. The code allows to import and image, from which I want to extract the coordinates. Some prompts ask the user about size and extent of the diagram, after which I would like to set up a coordinate grid by clicking the origin, and the end point on the x- and y-axes respectively. The idea is to use these 3 sets of coordinates and transform them into

as I am developing for iPhone, I've just bought an iPhone 4 to test my application which needs to measure the coordinates of my location. I don't have any Internet (3GS, GPRS or whatever...) on my iPhone and the problem is: 1) Without internet I get a 1744m horizontal accuracy, and that's very bad. (I've also tested the accuracy in other applications too, and it is always as bad or worse) 2) With WiFi-Internet I get a 80m horizontal accuracy. Is that normal? What can I do to improve my coordinates-measurement accuracy? Thanks in advance for any help. From my experience you need cellular data

I have been working with OpenCV for a fairly short time, and have performed Canny Edge Detection on an image, and also performed dilation after that to further separate the object (in my case a square) from the background. My problem, now is to identify graspable regions in 2D using an algorithm that requires me to handle co-ordinates of the points in those edges. Is there any way I can use OpenCV to get the co-ordinates of the corners so I can find the equation of the lines forming the edge of the square? I know the size of the square. My problem involves 2D co-ordinate geometry, and hence

Hi guys I am trying to make an app that once the user taps on a map it gets the coordinates of that specific point. Among others i have also read that: Get coordinates on tapping map in android It seems like the most relevant post but what I want to do is to be able to tap anywhere on the map not on an marker/overlay item. In fact I want to create a marker in that specific point that the user tapped and get the coordinates of it. Is that possible? Thanks Mike CommonsWare Yes. In fact, the answer I gave in that other question is what you need. Should be trivial with a little bit of math. You

I got a raw Longitude/Latitude data whose format cannot be processed by R map. So I wonder if there are some R functions or algorithms to help me to convert those raw data into a readable format. (Maybe UTM) Here is the raw data I had: Latitude: "32-14-23 N" "31-04-27 N" "33-45-28 N" Longitude: "121-22-38 W" "119-30-05 W" "122-47-52 W" I wish to convert the format as(the sample below is mock data): Longitude: -2.748 Latitude: 53.39 Looks like you have data in degree / minute / second format and you want it in decimal format. You can use the char2dms function in the sp package to go from

Say that I have an element inside a div (or any other containing element, or perhaps just in the body of the document). How do I get the (x,y) coordinates of that element, relative to its container? And I need to be able to do it in pure Javascript... Use the below document.getElementById("elementId").offsetTop; document.getElementById("elementId").offsetLeft; The offsetTop and offsetLeft properties are relative to offsetParent so you can get an element's position relative to its parent for free. If you want the position relative to the entire body then you need to traverse the offsetParent
