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

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:

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.

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.

Upload Excel latitude longitude in QGIS as Spatial Layer and save as Shapefile. When you have collection of point data i.e latitude and longitude, stored in Excel file in different column, then you can easily view and Save it as Vector layer file in QGIS(Quantum GIS). Well after uploading Excel latitude longitude values as spatial layer, you are only one step back, to convert the Excel data in Shapefile or KML or any vector file.

Before starting the exercise, you need to have a data excel file, which should be convert to Comma Delimited .csv file(Depends upon your choice, Comma delimited is common). To convert Excel file in .csv file, open the file and select save as type “CSV (Comma delimited) (*.csv)”. Name the file and save it.

Note: If you are using old version of QGIS then, do download and install plugin “Add delimited text layer”. To install a plugin,
Go to Plugins -> Manage and install Plugins, search for “Add delimited text layer“, and install it.

Steps to Upload Excel latitude longitude in QGIS as Spatial Layer

You should have an already downloaded and installed QGIS , before going through this steps.

1.) Open up QGIS and click on layer, from menu tab and select Add delimited text layer.

2.) Browse the already created .csv excel file, which has latitude and longitude coordinates.

3.) By default, if your column is named as latitude and longitude, then, X will be mapped to longitude and Y will be mapped to latitude. Select OK after mapping X and Y.

4.) Select the desired coordinate reference system and press OK, the file get uploaded as Spatial layer in QGIS.

Well if you want to convert this uploaded Spatial layer in Shapefile or KML or any other vector file, select on layer, and click on save as. In the open window, select the desired format in which you want to save the file. Done. I suppose this tutorial would be helpful to you. If you are facing any problem, then do comment below.
