Here`s an alternative. pic = Import["http://i.stack.imgur.com/4xyhd.png"] Let's say you are lazy and you don't want to write mathematical equations. We can use built-in transformations to create domain, image of transformation, and create InterpolationFunction based on this data. data = Join @@ Table[{lat, long}, {lat, -89, 89}, {long, -179, 179}]; ...

data = Cases[ Import[FileNames["*.dat"][[1]]], {a_, b_, c_} :> {b, Mod[a, 360, -180]}]; (*thanks to bbgodfrey*) To show points you have to stick with GeoGraphics. GeoListPlot is designed for Entities. To add something more to the question I changed Ra to hours. GeoGraphics[{Red, Point@GeoPosition@data}, GeoRange -> {All, ...

Import data (from wherever it is located): rad = Import["C:/Temp/DadosRad2014_RADECVELOC_15124_1024.dat"] Reverse first two elements of each sublist of rad, assure that RA lies in between -180 and 180, and discard third element; p = Cases[rad, {a_, b_, c_} -> {b, Mod[a, 360, -180]}]; Fix GeoGridLines, adjust ImageSize, and adjust FrameTicks and ...
