I have Gmaps embedded in my site which pulls out a list of dealers from my database around the world and plots their location with a marker based on the dealer postcode in Gmaps. This works great however I need to extend this functionality to support dealers who do not have a postcode but rather, they are assigned to Countries.
So for example, Test Dealer could be assigned to Germany and Belgium so I need to somehow get a generic longitude and latitude value for the country names "Germany" and "Belgium" and then show a marker for those long/lat values.
Is this possible?
If so, where do I start?!
Thanks for reading.

Try using google's geocoder. Just provide a generic address, in your case a country and it will return the center point of that country together with the coordinates(latitude and longitude)
Here's a link. https://developers.google.com/maps/documentation/javascript/geocoding

I want to create a map for showing the number of products selling in a particular district of India. in the backend, I have data like "West Delhi" name of the district and total count.I want to display the data in ant vision L7 district map. But not able to understand How they are consuming the data.
I have a retail database in Arabic, the addresses are written in Arabic, I have found a way to turn the letters to numbers to maybe make it easier for me, however, I am struggling to filter only the city name from the columns.
The problem is that the address is very specific, they are more of directions and they are generally written in the format of ( city, street, building name, nearby landmark ) but most of the time it's only written as the city only.
Is there a way to extract only the city from all the addresses?
I'm using Google Data Studio to track sales. I'm trying to utilizes the Geo Map to show the locations of "active" clients ( I have established a filter for active clients already).
I'm using City as the Dimension and Total sales as the metric. However, my Zoom Area option just show "Invalid Field" and doesn't let me change to anything else.
I have a Country Code, Region Code, City, State fields for location. I don't have a Zip Code location.
How do I changed by Zoom Area to Zoom in on the Country of a particular Country Code?
You have to change the data type of your fields to Geo data types respectively (like if you have a text field Country representing Country then change this to Geo data type Country) on your source.
Go to "Resource > Manage added data sources > Edit" and change the data type of the field.
There are APIs for accessing the current weather based on latitude and longitude, but I don't see any way to get the latitude and longitude of a county.
The Yahoo Weather API uses WOEIDs to select location, and WOEIDs exist for both cities and counties.
I am analysing app data which contains lat value and lon value of a user visited places. I was able to export the data to tableau and plot it on the map but I want to find the name of place for each pair of lat and lon.
One solution could be, if I get a table of three columns (Lat, Lon, Place) then I can join it with my user data table to find the name of a place at a given Lat and Lon.
My question is, do we have a ready made table with the above three columns which I can import in my SQL-Server? I am interested in places of UK or London. Is there any other approach to achieve it?
You can get this from the Ordinance Survey which should get you lat, long, postcode;

You'll then need another data source to map the postcode to location name (e.g. town, county etc). See the similar post below;
Where can I find a list of all UK _full_ postcodes including street name and their precise coordinates?
It might take a little fiddling about, and you're always going to have the issue with data being a little out of date but it should be good enough.
I wrote an API wrapper in R for postcodes.io, which is a free UK postcode database. Check the original documentation so that you could create an API wrapper in your language of choice. Wrappers in languages other than R are also available.
If you use R, then type you can get the place names in the following way:
if (!require("devtools")) install.packages("devtools")
devtools::install_github("erzk/PostcodesioR")
library(PostcodesioR)
rev_geo <- reverse_geocoding(0.127, 51.507)
It will return a list with extensive information about the latitude and longitude, e.g. wards, NUTS, administrative district, county, parish, consituency, CCG and many more.
There is also a bulk_reverse_geocoding() function which takes several lat and lon inputs.
