问题 F3 c8 42 14 - latitude //05.13637° should be nearby this coordinate 5d a4 40 b2 - longitude //100.47629° should be nearby this coordinate this is the hex data i get from GPS device, how to convert to readable coordinate? i don't have any manual document.please help.thanks 22 00 08 00 c3 80 00 20 00 dc f3 c8 42 14 5d a4 40 b2 74 5d 34 4e 52 30 39 47 30 35 31 36 34 00 00 00 this is my full bytes i received,but the engineer told me that F3 c8 42 14 is latitude and 5d a4 40 b2 is longitude 回答1: I

问题 I need to sort a coordinate list for a rectangle counterclockwise, and make the north-east corner the first coordinate. These are geographic coordinates (i.e. Longitude, Latitude) in decimal form. 1 For example, here are the 4 corners of a rectangle, starting with the north-west corner and moving clockwise: [ { "lat": 34.495239, "lng": -118.127747 }, # north-west { "lat": 34.495239, "lng": -117.147217 }, # north-east { "lat": 34.095174, "lng": -117.147217 }, # south-east { "lat": 34.095174,

问题 I have an SVG file coming from Inkscape, Illustrator, or any other application. I want to convert the shapes to lineto , moveto , curveto format. What I want is something like: ./Appname svgfile outfilewithpath I will give the SVG file as an argument, then my application will convert the object into the respective paths. 回答1: Inkscape has a command-line interface. Use the Inkscape man page along with the verb source for reference: The ObjectToPath verb converts an object to a path: inkscape

问题 I'm trying to create an algorithm that orders coordinates around one certain point, in this case; the middle point. I have found: this post, and I came across this reply: - Find the center of the "circle," i.e., the average X and average Y - Shift the X and Y values so all are relative to the new center. - Convert to polar coordinates and sort by angle. Since I am relatively new to this kind of algorithms I decided to ask it here. The reply written above makes somewhat sense to me, but I have

问题 I'm having a problem locating anything on converting RAE to XYZ. If I am on a WGS84 spheroid, at say position -742507, -5462738, 3196706 and I detect an object at a range of 30km, azimuth of 310, and elevation angle of 18 degrees how can I convert that to ECEF XYZ coordinates? Thanks. 回答1: It appears that there is no straight forward process to do this. The best method I found is to convert from RAE coordinates to SEZ coordinates, then from SEZ coordinates to ECR coordinates. Here is some C#

问题 is it possible to get the x and y coordinates of a touch? If so could someone please provide a very simple example where the coordinates are just logged to the console. 回答1: Using touchesBegan Event - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [[event allTouches] anyObject]; CGPoint touchPoint = [touch locationInView:self.view]; NSLog(@"Touch x : %f y : %f", touchPoint.x, touchPoint.y); } This event is triggered when touch starts. Using Gesture Register

问题 I have a data table with nrow being around a million or two and ncol of about 200. Each entry in a row has a coordinate associated with it. Tiny portion of the data: [1,] -2.80331471 -0.8874522 -2.34401863 -3.811584 -2.1292443 [2,] 0.03177716 0.2588624 0.82877467 1.955099 0.6321881 [3,] -1.32954665 -0.5433407 -2.19211837 -2.342554 -2.2142461 [4,] -0.60771429 -0.9758734 0.01558774 1.651459 -0.8137684 Coordinates for the first 4 rows: 9928202 9928251 9928288 9928319 What I would like is a

I've been having fun rendering charts and graphs from co-ordinates lately, and I'm fascinated by using matrices to transform co-ordinate spaces. I've been able to successfully scale and invert 2 dimensional co-ordinate spaces, but now my appetite is whetted. :) Where can I go for clear, informative, (free),
