  • Struggling to convert latitude and longitude to x and y coordinates (geo2xy)

    Hello
    I have a dataset of latitude and longitude points that I need to convert to X and Y coordinates.
    I have installed "geo2xy" and tried to use it by the resulting points just don't make any sense.

    Below is an example with some made up data. Can anyone see what I might be doing wrong?

    Many thanks
    Anna

    Using Stata SE/14.2

    ------------------------------------

    clear

    set obs 2

    gen latitude=-35.2729 in 1/1
    replace latitude=-35.204 in 2/2

    gen longitude=150.094 in 1/1
    replace longitude=162.125 in 2/2

    list

    geo2xy latitude longitude, gen(y x)

    list


    +----------------------------------------------+
    | latitude longit~e x y |
    |----------------------------------------------|
    1. | -35.2729 150.094 234.73351 -154.83626 |
    2. | -35.204 162.125 243.28889 -154.77627 |

    You are doing nothing wrong and the results are correct. You are using the default projection (Web Mercator) and the resulting planar coordinates are relative to the map's origin (top-left corner).
