Questions on the application of Mathematica to geography, including the use of the CountryData and CityData functions. Not to be confused with geodesy.
I'm using GeoGraphics and Polygon[Interpreter["USState"]["Colorado"]] to create a map of Colorado and several bordering states. With automatic GeoStyling, I get a decent map with cities and roads indicated.
I am plotting some data points on top of…
I would like to create a map which will show lakes and rivers together with elevation contours and contour labels. What is the simplest way to do this with GeoGraphics in version 10?
The solution I have (below) looks much too convoluted.
I need to…
Suppose I do:
GeoGraphics[Entity["City", {"Eureka", "California", "UnitedStates"}]]
What do folks do at this point to zoom in to various parts of the image?
In GeoListPlot the locations are supposed to be GeoPosition or Entity objects representing entities with geographic coordinates.
But say I have a few exact addresses that I'd like to plot (with callout labels):
addresses = <|

As I understand,first of all I should to get the country's map and the river's list.
To get country map is simple:
GeoGraphics[Polygon[Entity["Country", "Belarus"]]]
Also I get the list of all world rivers:
EntityList["River"]
but I can't get the…
I'd like to obtain a country map of France, as polygon xy positions so I can adjust the borders.
Currently I'm using:
i= GeoGraphics[{GeoStyling[None], Polygon[France (country)]}, GeoBackground -> None, GeoZoomLevel->1]
Which returns an image.
I…
I am writing a research proposal for a project on voter turnout as related to proximity to mass transit. The first part of my project would require geocoding hundreds of thousands of addresses, but I'd rather not have my laptop running ArcGIS for…
I'm importing the NGA ASAM piracy database into Mathematica for analysis.

I am trying to convert NAD 83 State Plane New York Long Island coordinates to Latitude/longitude. Below is my code - what am I doing wrong?
LatitudeLongitude[GeoPosition[{172248, 1002321, 0}, "SPCS83NY04"]]
According to Wikipedia
Of the 193 widely recognized countries, 178 have an official language at the national level
(NB:or more than one)
The only exceptions are:
Cyprus, Czech Republic, Denmark, Eritrea, The Holy See, Luxembourg, San Marino,…
I would like to construct Turkey's map using Geocoordinate of each city. This link has all coordinate of of cities but I don't know how to extract the data from website. I did manually two cities and it seems it is working.
hatay={{36.0616,…
I can plot the elevation data by this code
entity = Entity["AdministrativeDivision", {"Berlin", "Germany"}];
latlon = Transpose[GeoBounds[entity]];
elevation = Reverse[QuantityMagnitude[GeoElevationData[latlon]]];
ListPlot3D[elevation, Boxed ->…
I have a problem with GeoRegionValuePlot. These are the settings:
europe = CountryData[
EntityClass["Country", "EconomicAndMonetaryUnion"]]
to fetch the entities of EU. Now I want to plot different data. Everything is fine, but for "PhoneLines"…
I am looking to list with Geo commands all the cities such that
Point is 333 miles from Houston
Point is 755 miles from San Antonio
Point is 460 miles from El Paso.
How do I write up the code that gives a list of cities that meet three criteria?
