Latitude, longitude and geocodingThe coordinates behind every Google Maps lead
Two numbers place any business on Earth. Here is what they mean, how geocoding creates them, and why they turn a flat list into a working map.

Key takeaways
Latitude and longitude are two angles, in degrees, that pin any point on Earth. Latitude runs north and south, longitude runs east and west.
Geocoding turns a written address into those coordinates. Reverse geocoding turns coordinates back into an address.
Coordinates are what let scraped Google Maps leads live on a map, split into territories, and route into a driving plan inside a mapped CRM.
Definition
What latitude, longitude and geocoding mean
Latitude is the angle, measured in degrees, that tells you how far north or south a point sits from the Equator, ranging from -90 at the South Pole to 90 at the North Pole. Longitude is the angle that tells you how far east or west a point sits from the Prime Meridian, ranging from -180 to 180. Geocoding is the act of converting a text address into that latitude and longitude pair so software can place it on a map.
A single coordinate pair looks like 40.4168, -3.7038. That is the center of Madrid. The first number is latitude, the second is longitude, and the order is always latitude first in Google Maps data. Written this way, any place on the planet reduces to two numbers that never point at two different spots.
The reference frame that these numbers assume matters. Google Maps, GPS receivers, and almost every consumer mapping system express coordinates in the WGS84 datum. When you export a business from a Google Maps scrape, the latitude and longitude you receive are already in this standard, so they drop straight onto any modern map without conversion.
Capture coordinates for every business you find
The Vonsel extension pulls latitude and longitude with each result, so your leads are map ready the moment you export. Free download. No trial, no credit card.
These are the words you will meet whenever location data shows up in a Google Maps export. Keep this table close when you open a fresh CSV.

Example
Latitude
North to south angle from the Equator (-90 to 90)
40.4168
Longitude
East to west angle from the Prime Meridian (-180 to 180)
-3.7038
Geocoding
Address turned into coordinates
"Gran Via 1, Madrid" to 40.42, -3.70
Reverse geocoding
Coordinates turned into an address
40.42, -3.70 to "Gran Via 1"

Notice that geocoding and reverse geocoding are mirror images. Both are defined in the official Google Geocoding API documentation, which sales tools lean on behind the scenes to keep addresses and coordinates in sync.
Precision
How many decimals do you actually need
The number of decimal places in a coordinate decides how tightly it points. More digits mean a smaller circle of uncertainty. For finding a storefront, five or six decimals is plenty.

Survey grade accuracy
Google Maps typically returns six decimal places. That is far more than a field rep needs to park outside the right door, but the extra precision costs nothing and keeps your data honest. If you also collect a Plus Code, you get a short human friendly reference that maps back to the same spot.
An address is a label. Coordinates are a location. The label can be misspelled, abbreviated, or duplicated across a dozen towns, but the coordinate pair points at exactly one place on Earth. That is why serious lead work runs on numbers, not strings.
In your data
Where coordinates show up in a scrape
When you scrape a Google Maps result, latitude and longitude arrive as two of the standard columns, sitting alongside the name, phone, category, and rating. You can see the full picture in our guide to Google Maps data fields, but the coordinate pair is the one that unlocks everything visual.
Reverse geocoding runs the other way. If you only have a coordinate, a lookup against Google's reverse geocoding endpoint rebuilds the street, city, and postal code. This is how a captured pin becomes a mailing address you can put in an email or a proposal.
Most scraping tools stop after handing you these numbers in a spreadsheet. That is useful, but a column of coordinates is not a map. To turn 40.4168, -3.7038 into something a salesperson can drive, the data has to move into a system that reads coordinates natively.
From coordinates to a live map
Every business you capture lands as a pin inside the Vonsel dashboard, ready to cluster and route. Free download. No trial, no credit card required.
The extension is the means. The point is what the Vonsel dashboard does with the numbers. Because every lead carries a real coordinate pair, the mapped CRM plots your whole list on an interactive map the moment it lands, instead of leaving you to squint at a spreadsheet.
From there, coordinates power the parts of prospecting that addresses alone cannot. You can draw territories by neighborhood, group leads by drive time, and let the Sales Intelligence layer build an optimized route so a field rep visits more businesses in a day. The same pins feed AI email per business and the value added, context rich databases that sit at the heart of the platform. See the full picture on the features page.
This is also why coordinate quality beats raw volume. A clean, correctly geocoded list you built yourself outperforms a bulk file of stale rows, a point we make in Google Maps data vs bought lists. When you scrape your own leads, you know exactly where each pin came from and when.
An address gets you a label. Coordinates get you a route
Getting started
Collect map ready leads yourself
You do not need to write geocoding code or juggle an API key to get clean coordinates. The Vonsel Chrome extension captures latitude and longitude with each Google Maps result and sends them straight into the dashboard, where they become pins you can act on. If addresses are your priority, our walkthrough on extracting addresses from Google Maps shows the same flow.
Understanding the vocabulary also keeps you on the right side of the rules. Coordinates for a business are commercial location data, which is very different from personal data, a distinction worth reading up on in is it legal to scrape Google Maps. Once the concepts click, two numbers stop looking like noise and start looking like a map of your next quarter.
Turn addresses into a working map
Add the extension, search Google Maps, and watch every business drop onto your dashboard as a pin. Free download. No trial, no credit card. Explore features or read more guides.
What is the difference between latitude and longitude?
Latitude measures how far north or south a point sits from the Equator, from -90 to 90 degrees. Longitude measures how far east or west a point sits from the Prime Meridian, from -180 to 180 degrees. Together they pin a single location on Earth.
What is geocoding in Google Maps data?
Geocoding is the process of turning a text address into latitude and longitude coordinates so it can be placed on a map. Reverse geocoding does the opposite: it turns coordinates back into a readable address.
Why do lead lists need coordinates?
Coordinates let you plot every business on a map, group leads by territory, and build optimized driving routes. A plain address list cannot do any of that until it is geocoded first, which is why Vonsel captures the coordinate pair with every result.
