how to find course between lat and long

For modern microprocessors with 8 byte IEEE floating point numbers, the spherical law of cosines can be used to compute distance between 2 latitude longitude

points. The law of cosines can be expressed in Excel as: =ACOS ((COS (LAT1)*COS (LAT2)*COS ((-1*LON2)- (-1*CLON2)))+ (SIN (LAT1)*SIN (LAT2)))*r

How do I enter latitudes and longitudes in Excel?

Enter latitude and longitude of two points, select the desired units: nautical miles (n mi), statute miles (sm), or kilometers (km) and click Compute. Latitudes and longitudes may be entered in any of three different formats, decimal degrees (DD.DD), degrees and decimal minutes (DD:MM.MM) or degrees, minutes, and decimal seconds (DD:MM:SS.SS).

How do you find the distance between lat and long points?

For this divide the values of longitude and latitude of both the points by 180/pi. The value of pi is 22/7. The value of 180/pi is approximately 57.29577951. If we want to calculate the distance between two places in miles, use the value 3, 963, which is the radius of Earth.Apr 9, 2021

How do you find lat long from distance and bearing?

Here is the formula to find the second point, when first point, bearing and distance is known:latitude of second point = la2 = asin(sin la1 * cos Ad + cos la1 * sin Ad * cos θ), and.longitude of second point = lo2 = lo1 + atan2(sin θ * sin Ad * cos la1 , cos Ad – sin la1 * sin la2)

What is the distance between two longitude?

69.172 milesA degree of longitude is widest at the equator with a distance of 69.172 miles (111.321 kilometers). The distance gradually shrinks to zero as they meet at the poles. At 40 degrees north or south, the distance between a degree of longitude is 53 miles (85 kilometers).Jan 24, 2020

How do you calculate distance in nautical miles?

Measuring Distance on a Nautical Chart1' (minute) of latitude = 1 nautical mile.1∘ degree of Latitude = 60' (minute) or 60 nautical miles.Land mile = 1609m.Nautical mile = 1852m / 1.15 land miles.Jun 15, 2019

How many seconds are in a minute?

The degrees part remains the same, but minutes and seconds need to be converted into their percentage of a degree and combined. There are 60 minutes in a degree and 60 seconds in a minute (which means 3,600 seconds in a degree). Therefore, divide minutes by 60 and seconds by 3,600. The overall formula:

What is geocoding in Excel?

Geocoding is the conversion of street addresses to latitude and longitude data that can be mapped. Now, there are two ways to geocode latitude and longitude from an Excel spreadsheet: the hard way and the easy way.

Getting Started

For those who are in a rush for the solution and don't need all the background information, jump to the longitude latitude code. Or download the calculation workbook, and enter your longitude and latitude.

Accuracy is Important

A formula that is accepted to provide results that are accurate to within millimeters is known as Vincenty's formula. Naturally the accuracy of the results depends in large part on the accuracy of the latitude/longitude pairs describing the two points.

Excel Formulas for Distance

There are numerous Excel worksheet functions that will return an initial heading from one point to the destination point for a Great Circle path between them and similar formulas to return the distance between them.

Creating Excel Code for Distance

The basis for the solution presented by T. Vincenty can be found here:

Working With Angles in Excel

But before using the function, there are a few preliminary steps that must be considered. Most significant is that Excel and VB works with angles expressed in radians, not as decimal values of the angles, nor from their initial "plain English" representation.

Converting to Radians

After converting the standard notation to a decimal value, we still have to convert that to radians and deal with the sign of the radian result.

The Final Solution

Copy all of the code below and paste it into a regular code module in your workbook. Instructions for placing the code into a regular module are here: Copy Excel VBA Code to a Regular Module

Geodesic

A geodesic is the shortest path between two points on a curved surface. It is the most common interpretation of where a "user is heading" (from the question), since it is the shortest and most direct. An inverse geodesic calculation can be solved using GeodSolve. You can also use the online interface. This tool has the input/output:

Rhumb line

A rhumb line connects two coordinate points with a constant azimuth (or bearing). An inverse rhumb line calculation can be solved using RhumbSolve. You can also use the online interface. This tool has the input/output:

What are latitude and longitude?

Latitude and Longitude are the units that represent the coordinates at geographic coordinate system. To make a search, use the name of a place, city, state, or address, or click the location on the map to find lat long coordinates.

What is the equator?

The equator is the line with 0° latitude. The longitude has the symbol of lambda and is another angular coordinate defining the position of a point on a surface of earth. The longitude is defined as an angle pointing west or east from the Greenwich Meridian, which is taken as the Prime Meridian.
