Whereas the Mercator projection uses a vertically-oriented cylinder projection tangent to the equator. The major difference between this projection is that it uses a spherical formula at all scales. In the Map Provider drop-down list, choose Google Maps. # lon-lat of center of Munich (Marienplatz)Ĭorrect result (which I verified on a webmercator map) (1288648.2290397931, 6129702. The Web Mercator projection uses a modified version of the Mercator projection and has become a default map projection for web mapping. From the MAPublisher Toolbar, click Export> Export Document to Web Tiles. So, to make things clear in the code, my suggested variation of Jacopofar's solution using always_xy=True is If you prefer to keep your axis order as always x,y, you can use the always_xy option when creating the. You can check the axis order with the class. The axis order may be swapped if the source and destination CRS’s are defined as having the first coordinate component point in a northerly direction (See PROJ FAQ on axis order). This is in accordance to the ISO19111 standard PROJ respects the axis ordering as it was defined by the authority in charge of a given coordinate reference system. Since there is some confusion about the order of x, y or lon, lat in pyproj I want to summarize the info that I just found after also messing up the order when reusing the solution from Jacopofar's answer.įrom the FAQ - Why is the axis ordering in PROJ not consistent? Is there a minimum working example I could see to achieve the mapping in python using pyproj?īeware! Order of x, y or lon, lat might not be intuitive I suspect the formulas above have some sort of precision issue and I would like to rely on a library like pyproj hoping to minimise projection errors. However I would like to achieve this using pyproj syntax, but I am lost in the details of the string I should pass to build a projection using Web Mercator EPSG:3857. Print('latitude web mercator y: '.format(lat2y(ts_gm), lon2x(ts_gm))) MAPublisher is fully compatible with Adobe Illustrator CS6 and the latest Creative Cloud (2015) on both 32 bit and 64 bit systems. Then I can use them to get for example the projection of Trafalgar Square (taking the GPS coordinates from the Google Maps URL): ts_gm = The latest release of MAPublisher is available for Windows 7/8 and Intel-based Mac systems. Return math.log(math.tan(math.pi / 4 + math.radians(a) / 2)) * RADIUS century to better depict the spherical surface of the earth on a flat map. RADIUS = 6378137.0 # in meters on the equator A satellite in an inclined orbit traces a sinusoidal wave on a Mercator map. # derived from the Java version explained here: I took the Java version and ported it to Python: import math I've created a couple of functions using the math package from python 3.5 to transform GPS coordinates to x/y web mercator (pseudo mercator) as explained here:
