Convert – Degree Minute Seconds to Degree Decimal Minutes to Decimal Degree format – Latitude Longitude

Convert – Degree Minute Seconds to Degree Decimal Minutes to Decimal Degree format. Geographical location information is represented in terms of Latitude and Longitude, where Latitude gives the angular distance of a point from equator to elevation either north or south, and Longitude gives the angular distance of a point east or west of the meridian. This Angular distance values of Lat and Lon is either represented in Degree, Minute, Seconds(dd,mm,ss) number system or Decimal Degree number system. So let us discuss about, how to represent the location with Latitude and Longitude, their value range and how to convert them with the tool.

Latitude values Range:

Point on Equator line is calculated as 0° latitude, while North pole as 90°N and South pole as 90°S. Latitude values range in between 0° and 90° in positive
(representing north) and in negative (representing south) values.

Longitude values Range:

Prime Meridian or Greenwich meridian is defined as 0° longitude. Longitude values ranges from 0° to 180° east or from 0° to 180° west.

Latitude and Longitude Representation – Different converted formats:

Generally in three formats, latitude and longitude values are represented. Let us take example of each format, by taking latitude longitude of San Antonio.
1.) Degree Minutes Seconds :
For example: 29° 25′ 26.5152″, -98° 29′ 37.6974″

2.) Degree Decimal Minutes:
For example: 29° 25.441916666667’ , -98° 29.6283’

3.) Decimal Degree:
For example: 29.424032, -98.493805

Format of Lat lon - Degree Minute Seconds, Degree Decimal Minutes, Decimal Degree format
Format of Lat lon – Degree Minute Seconds, Degree Decimal Minutes, Decimal Degree format

Convert – Degree Minute Seconds to Degree Decimal Minutes to Decimal Degree format

Earth equator line is divided in 360 equal parts, each part represents a degree distance, where 1°=111.32 Km. Every Degree is further divided in 60 minutes. This means, 1 minute = 111.32/60 = 1.85 Km, and every minute is divided in 60 seconds. So 1 seconds = 1.85/60 = 0.0309 Km.

Convert Degree Minute Seconds to Degree Decimal for the Latitude Longitude values:

As 1°=60’=3600”, so we can compute degree decimal by:

d = degree + minute / 60 + seconds/3600

Let us take an example: Compute 29° 25′ 26.5152″, -98° 29′ 37.6974″ to degree decimal:

Latitude to Degree Decimal = d = 29 + 25/60 + 26.5152/3600 = 29.42432
Longitude to Degree Decimal = d = -(98 + 29/60 + 37.6974/3600) = -98.493805

Tool to convert lat lon values from degree minute seconds to degree decimal:


LATITUDE :Degree= Minute= Seconds=

LONGITUDE :Degree= Minute= Seconds=


Latitude :

Longitude :

Convert Degree Minute Seconds to Degree Decimal:

Again, as 1°=60’=3600”, we would compute Degree, Minute and Seconds separately from Degree Decimal.

  • Degree = integer part of Decimal degree = int(ddd.dd) = ddd.
  • Minute = integer part of ((Decimal degree – Degree computed above) * 60) = int(ddd.dd – ddd) * 60.
  • Seconds = (Degree Decimal – degree – Minute/60) * 3600 = (ddd.dd – ddd – m/60)*3600

Let us take an example. Compute 29.424032, -98.493805 to Degree Minute Seconds format:

Degree = int(29.424032) = 29
Minute = int((29.424032 – 29) * 60) = int (25.44192) = 25
Seconds = (29.424032 – 29 – 25/60) * 3600 = 26.5152″

So latitude = 29° 25′ 26.5152”

Similarly computing longitude of -98.493805, we get the degree minute second to -98° 29′ 37.6974.

Tool to convert lat lon values from Degree Decimal to Degree Minute Seconds:


LATITUDE :
LONGITUDE :


Latitude :

Longitude :

Convert – Degree Minute Seconds to Degree Decimal Minutes:

Fetch the Seconds number, and divide it by 60, and then add the result with minute,

For example: Convert 29° 25′ 26.5152” to Degree Decimal Minute:

  • Here Seconds = 26.5152,
  • so dividing it by 60 i.e 26.5152/60 = 0.44.
  • Now add this with Minute, we will get 29° 25.44, which is in Degree Decimal Minutes format. If you multiply again 0.44 by 60 you will get again Degree Minute seconds format.

Formula to Find Bearing or Heading angle between two points: Latitude Longitude

Formula to Find Bearing or Heading angle between two points. Bearing or heading angle is used to define navigation generally in the field of aircraft or marine or Vehicle navigation or while working for land surveying. So what’s the heading or bearing? How we can find bearing between the two points on earth, with the formula? Or How we can find the other point, when one point, actual traveled distance and bearing is given? Let us discuss all this points, followed with the example and experiment with the tool for calculating bearing provided in the post.

Formula to Find Bearing or Heading angle between two points: Latitude Longitude
Formula to Find Bearing or Heading angle between two points: Latitude Longitude

Bearing can be defined as direction or an angle, between the north-south line of earth or meridian and the line connecting the target and the reference point. While Heading is an angle or direction where you are currently navigating in.  This means to reach a particular destination you need to adjust your heading direction with the bearing. Generally a ‘compass’ is an instrument, which gives you the direction information for navigation. You must refer Haversine distance formula before going through this post.

Calculating Bearing or Heading angle between two points:

So if you are from GIS field or dealing with GIS application, you should know bearing and how to calculate bearing with formula. Let us look on formula and tool for bearing:

  • Let ‘R’ be the radius of Earth,
  • L’ be the longitude,
  • ‘θ’ be latitude,
  • β‘ be Bearing.

Denote point A and B as two different points, where ‘La’ is point A longitude and ‘θa’ is point A latitude, similarly assume for point B. Bearing would be measured from North direction i.e 0° bearing means North, 90° bearing is East, 180° bearing is measured to be South, and 270° to be West.

Note: If bearing is denoted with +ve or –ve initials whose values lies between 0° to 180°, then –ve is denoted for South and West sides.

Formula to find Bearing, when two different points latitude, longitude is given:

Bearing from point A to B, can be calculated as,

β = atan2(X,Y),

where, X and Y are two quantities and can be calculated as:

X = cos θb * sin ∆L

Y = cos θa * sin θb – sin θa * cos θb * cos ∆L

Lets us take an example to calculate bearing between the two different points with the formula:

  • Kansas City: 39.099912, -94.581213
  • St Louis: 38.627089, -90.200203

So X and Y can be calculated as,

X =  cos(38.627089) * sin(4.38101)

X  = 0.05967668696

And

Y = cos(39.099912) * sin(38.627089) – sin(39.099912) * cos(38.627089) * cos(4.38101)

Y = 0.77604737571 * 0.62424902378 – 0.6306746155 * 0.78122541965 * 0.99707812506

 Y = -0.00681261948

***Convert θ into radians***

So as, β = atan2(X,Y) = atan2(0.05967668696, -0.00681261948) = 1.684463062558 radians

convert it into degree

           β = 96.51°

This means, from Kansas City if we move in 96.51° bearing direction, we will reach St Louis.

Formula to find a lat lon point, when bearing, distance and another lat lon is given

Let us assume a condition, where you want to find out the where will an Airplane will land up, if you have following details of that Airplane, i.e actual distance it will travel, the bearing and the starting point (lat,lon)?

  • Let first point latitude be la1,
  • longitude as lo1,
  • d be distance,
  • R as radius of Earth,
  • Ad be the angular distance i.e d/R and
  • θ be the 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)

Haversine Formula – Calculate geographic distance on earth

Haversine Formula – Calculate geographic distance on earth. If you have two different latitude – longitude values of two different point on earth, then with the help of Haversine Formula, you can easily compute the great-circle distance (The shortest distance between two points on the surface of a Sphere). The term Haversine was coined by Prof. James Inman in 1835. Haversine is very popular and frequently used formula when developing a GIS (Geographic Information System) application or analyzing path and fields.

You can use this Online Route Compass Tool, which calculates the distance based on haversine Formula and also computes the Bearing angle too :

Route Compass Online Tool to Compute Haversine Distance

Haversine formula - Calculate geographic distance on earth
Haversine formula – Calculate geographic distance on earth

Haversine formula:

Central angle Haversine can be computed, between two points with r as radius of earth, d as the distance between two points, \phi_1, \phi_2 is latitude of two points and \lambda_1, \lambda_2 is longitude of two points respectively, as:

\operatorname{haversin}\left(\frac{d}{r}\right) = \operatorname{haversin}(\phi_2 - \phi_1) + \cos(\phi_1) \cos(\phi_2)\operatorname{haversin}(\lambda_2-\lambda_1)

Haversine formula - Calculate geographic distance on earth
Haversine formula – Calculate geographic distance on earth

Law of Haversine:

To derive law of Haversine one needs to start the calculation with spherical law of cosine i.e cos a = cos b * cos c + sin b * sin c * cos A

One can derive Haversine formula to calculate distance between two as:

a = sin²(ΔlatDifference/2) + cos(lat1).cos(lt2).sin²(ΔlonDifference/2)
c = 2.atan2(√a, √(1−a))
d = R.c

where,

ΔlatDifference = lat1 – lat2 (difference of latitude)

ΔlonDifference = lon1 – lon2 (difference of longitude)

R is radius of earth i.e 6371 KM or 3961 miles

and d is the distance computed between two points.

Here is the example result delivered by Haversine Formula:

Lets take one of latitude-longitude for calculation distance,
NEBRASKA, USA (Latitude : 41.507483, longitude : -99.436554) and
KANSAS, USA (Latitude : 38.504048, Longitude : -98.315949)

Do compute the distance with the above written formula. Your answer would be 347.3 Km(kilo-meter). The snapshot demonstrate the same result with map below.
