Converting Longitude & Latitude to X Y on a map using Julia

Well, I went ahead and did this — let me know if it seems useful.

@Wedg somehow I missed your comment about the implementation in PlotShapefiles.jl, but oh well :slight_smile:

One nice (at least, IMO) thing the Geodesy.jl API provides is CoordinateTransformations.jl — based transformation objects so you can naturally create a whole pipeline of coordinate transformations.

TBH it feels a little dirty to provide this somewhat-broken projection in a package called “Geodesy”, but it’s undeniably needed as it’s ubiquitous in practice… Even the EPSG eventually had to give up and assign it an official code :laughing:

Hi @joa-quim, is there a way in Julia to convert from geographic coordinates (xº x’’ x’) to decimal coordinates to use in GMT?
Thanks.

Are you asking on how to do it from data in a file?
It’s automatic

println(String(read("lixo.dat")))
-10:19:58.800   40:46:37.200


gmtread("lixo.dat")
1×2 GMTdataset{Float64, 2}
 Row │   col.1    col.2
     │ Float64  Float64
─────┼──────────────────
