See how to calculate distance in Excel, using Latitude and Longitude, in this
tutorial by Excel MVP, Jerry Latham.

Jun 15, 2020 Some apps use decimal format (48.85833) while others return the
coordinates in degrees, minutes and seconds (48°51'29.99'). In this article I
will show you how to convert from one format to the other and vice-versa. Add
GPS coordinates to address. If you are looking to add GPS coordinates to your
address, please go to this page. Say that you have a list of cities in Excel and
need to know the latitude and longitude for each city. A new Geography Data Type
feature coming to Office 365 will make this easy. Check the Data tab in the
Excel ribbon. Do you have a new Data Type category with Stocks and Geography? If
you have the new features, read on. Bing Maps Api Get Latitude Longitude From
Address.


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.

The search for an accurate solution to this problem has led me to numerous sites
and attempted solutions. A long list of related sites is included at the end of
all of this, but the most crucial to what I've found to be the current end of
the road are these:

are several pushpins in the map.

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.

Why all the fuss over accuracy? Well, from what I've seen of other formulas,
especially those written as a single worksheet function, their values differ
quite a bit for what might be considered 'life critical' situations. Typically
they are short by some number of meters, typically about 20 to 30 feet per
statute mile, and after flying just 30 or 40 miles, I wouldn't care to land
several hundred feet short of the approach end of a runway, much less be off by
over 7 miles on a trip between Los Angeles and Honolulu.

Since the general tendency in dealing with these types of calculations is to
'measure it with a micrometer, mark it with chalk and cut it with an axe', what
we have here is a very precise micrometer to begin the measuring process with.


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.

But based on experience using them and comparing them to known measured
distances, the Vincenty method of calculating the distance between the points
has not been translated into a single Excel worksheet function, and very likely
cannot be at least not easily.

Because it relies on reiterative calculations to deal with points that are very
close to being on the exact opposite sides of the world, implementing it as even
a series of Excel worksheet formulas is a daunting task.


CREATING EXCEL CODE FOR DISTANCE

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

During my search I first found the movable-type.co.uk page which presented the
coded solution in JavaScript. That didn't do me much good as far as coming up
with an Excel VBA solution; so I continued the search and finally found the
lost-species.livejournal.com page!!

I thought the search was over. Almost, but not quite.

When I moved that code into an Excel code module I was confronted with two
sections that Excel not so politely informed me were 'too complex' for it to
evaluate. I managed to break those down into simpler statements that Excel could
deal with and that did not corrupt the final results. That is the sum total of
my contribution to the function provided below. I claim nothing more than that
small contribution.


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.

Consider this situation:

You have a Latitude represented as 10° 27' 36' S (10 degrees, 27 minutes 36
seconds South)

You need to get that into radians, and there is not a direct way to do it,
before we can get it to radians it has to be converted into a decimal
representation. We need to see it as: 10.46 which is the decimal equivalent to
10° 27' 36' and we need to take into consideration whether it is a North or
South latitude, with South latitudes being treated as negative numbers.

PHILIPPINES

Luckily Microsoft provides a couple of handy functions to convert standard
angular notations to their decimal equivalent, and back, at this page:

Those routines are included at the code section and one of them has a change
made by me to permit you to make a regular angle entry as

10~ 27' 36' S instead of 10° 27' 36' S

because ~ is directly accessible from the keyboard, while the ° is not.


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 routines and formulas here consider negative latitudes to be South latitudes
and negative longitudes to be West longitudes. While this may seem unfair to
those of us living in the western hemisphere, what can I say other than deal
with it!?

A decimal degree value can be converted to radians in several ways in Excel and
for this process, a simple function is used that is also included in the code
presented later.

The basic formula is

radians = angleAsDecimal x (Pi / 180)

where Pi is 3.14159265358979


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

Set up your worksheet to pass the latitudes and longitudes of the start and end
points as standard entries, then enter a formula to pass them to function
distVincenty().

Given two points with these coordinates:

Point 1:

 * Latitude: 37° 57' 3.7203' S
 * Longitude: 144° 25' 29.5244' E

Point 2:

 * Latitude: 37° 39' 10.1561' S
 * Longitude: 143° 55' 35.3839' E

The general format of the function call is:

=distVincenty( Pt1_LatAsDecimal, Pt1_LongAsDecimal, Pt2_LatAsDecimal,
Pt2_LongAsDecimal)

A raw formula would look like this [Note the double-double quotes after the
seconds entries]. The SignIt() function, provided as part of the code, converts
a standard angular entry to signed decimal value.

=distVincenty(SignIt('37° 57' 3.7203' S '), SignIt('144° 25' 29.5244' E'),
SignIt('37° 39' 10.1561' S'), SignIt('143° 55' 35.3839' E'))

You can use the ~ symbol instead of the ° symbol if it makes it easier for you:

=distVincenty(SignIt('37~ 57' 3.7203' S '), SignIt('144~ 25' 29.5244' E'),
SignIt('37~ 39' 10.1561' S'), SignIt('143~ 55' 35.3839' E'))

If the coordinates for Point 1 are in B2 and C2 and the coordinates for Point 2
are in B3 and C3, then it could be entered as

=distVincenty(SignIt(B2), SignIt(C2), SignIt(B3), SignIt(C3))

The result for the 2 sample points used above should be 54972.271, and this
result is in Meters.


PROBLEMS ENCOUNTERED

The initial code that I began working with generated 'formula too complex'
errors in two statements. These statements were initially broken into two pieces
and then those two separate calculations were 'rejoined' in a formula to obtain
their final result without the 'formula too complex' error.

During the preparation of this document, the package was tested in Excel 2010
64-bit and began returning #VALUE! errors for all input values. Investigation
determined that a portion of the already split formula to determine the
deltaSigma value was generating an overflow error. This error did not occur in
the 32-bit version of Excel 2010, nor in Excel 2003 (a 32-bit application).

The offending line of code was once again broken down into smaller pieces that
were eventually rejoined in a mathematically correct process that resulted in
the proper values being determined without resorting to any alteration of the
original algorithm at all.

These sections are noted in the comments in the code for Function distVincenty()
below.

THIS HELP GUIDE WILL SHOW YOU HOW TO TAKE A LIST OF ADDRESSES AND GET LATITUDE &
LONGITUDE COORDINATES.

To begin, you will need your addresses (street address with city and country;
just a city) in CSV or Excel format with one address per row. The address may be
in one column or across multiple columns (e.g.: a column each for street, city,
and country). Then consult the criteria below to find where you fit:

 * I have a spreadsheet with less than 5,000 locations and each street address
   is split up across multiple cells
   * GPS Visualizer (online)
   * QGIS (desktop)


GPS VISUALIZER

YOU WILL NEED ONE OF THE FOLLOWING FREE API KEYS: BING MAPS API KEY (GEOCODING
LIMIT UNCLEAR), GOOGLE MAPS API KEY (2,500 FREE REQUESTS PER DAY), OR MAPQUEST
API KEY (15,000 PER MONTH)


EXCEL MAC 2016 GET LONGITUDE LATITUDE COORDINATES FOR AN ADDRESS LOCATION

 1.  Ensure that your spreadsheet has the following column headers and is saved
     as a CSV:
     * Header: name; content: name of the point (e.g.: business name, hospital,
       person who lives there, etc.)
     * Header: address; content: street address (e.g.: 1 Main Street)
     * Header: city; content: city
     * Header: state or province; content: state or province spelled out (e.g.:
       Ontario instead of ON)
     * Header: country; content: country spelled out
 2.  Open your CSV in Notepad (Windows) or TextEdit (Mac), so there are no
     columns and rows but comma-separated data
 3.  Go to http://www.gpsvisualizer.com/geocoder/
 4.  Copy your data from Notepad/TextEdit into the Input textbox (we recommend
     that you do this in batches instead of 1000 at once)
 5.  In the Source dropdown, select which API key you have
 6.  Copy that API key into the API key textbox below
 7.  Click Start Geocoding
 8.  Wait...it takes about one second per location
 9.  Once the geocoding is complete, copy the contents of the Results as text
     box
 10. Paste the contents into a new Notepad/TextEdit document
 11. Save that document as a CSV (you may need to manually change the file
     extension when you save)
 12. Open the CSV in Excel to view and check your data in spreadsheet format.
     There will probably be errors, which is normal.
 13. You can now import that CSV into ArcMap (Add XY data), ArcGIS Pro (Add XY
     data), or QGIS (Add delimited text layer) and display the points
