Distance from Point To Line great circle function not working right. -

-

I need to get distance from distance / LNG point. I undoubtedly need to follow the great circle.

I found a great article on this

but the code is not working right. Either I am doing something wrong or missing something. This is the function in question. If necessary, look for the link for other functions. 

  var R = 3961.3 LatLon.crossTrack = function (lat1, lon1, lat2, lon2, lat3, lon3) {var d13 = LatLon.distHaversine Lat1, lon1, lat3, lon3); Var brng12 = lotalon. Bearing (lat1, lon1, lat2, lon2); Var brng13 = lotalon. Effect (lat1, lon1, lat3, lon3); Var dXt = Math.Sin (Math (D13 / R) * Math (Bronze13-Brande 12)) * R; Return DXT; }

lat / lon1 = -94.127592, 41.81762

latitude / lon2 = -94.087257, 41.848202

lat / lon3 = -94.046875, 41.791057

It reports 0.865 miles, the actual distance is 4.2 9 0.9 miles

How does any clue determine this? I'm not a mathematician, it's just long in the tooth programmer.

Most triangular tasks require radians. What degree are your angular measures? They may need to be changed using the normal formula:

2 * & pi; Radian = 360 degree

If you look under the formula for Harveyen formula, you will see:

(Note that the angles are in radians Should pass triangular tasks).

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
