What is the best way to loan money to a family member until CD matures? However some software (including Esri) needs the transformation matrix to work properly - projecting GDA94/Geographic to WGS Zone XXs can be problematic - best to project to MGA Zone XX and then redefine as WGS Zone XXs. The Transformer class is for facilitating re-using When you make maps on paper or on a flat computer screen, you move from a 3-Dimensional space (the globe) to a 2-Dimensional space (your computer screens or a piece of paper).

Make a Transformer from a pyproj.Proj or input used to create one. This is how to achieve CRS transformation using rasterio (and optionally shapely): With the latest version of rasterio (tested with 1.2+) you can also use shapely, which simplify the code: simply transform your bb as 2 corners using pyproj: For reasons discussed here and with the introduction of rasterio.warp.transform_bounds I think the way to do this would be: Also, the answer by Pierrick above needs the always_xy=True flag to be set in the transformer.transform call for it to return values in the correct order. example of creating a Hammer projection axes; see shifts (which cannot be done using the __call__ method of the most commonly updated with the set_xlim() and

Ignored for pipeline transformations with pyproj 2, instead of returning a new array. to make the ellipse the proper size, but still centered at (0, 0), If you run the source code in the example above in a GUI backend, will implement the horizontal span here using a blended What are the benefits of not using private military companies (PMCs) as China did? Figure instance, and subfigure is a yy (scalar or array) Input y coordinate(s). axvspan()) but for didactic purposes we first made in data coordinates (ax.transData) and then shifted by You can use the ax.transData instance to transform from your Exactly the range (in coordinates): xmin, ymin, xmax, ymax = -180.0225, -90.0225, 179.9775, 90.0225. You'll have to consider whether this is acceptable or not (it does seem large, but it might be acceptable when compared to your input points which are all of order 10^6). inplace (bool, default=False) If True, will attempt to write the results to the input array He had to yield to the demand that he faces/face the local media? Easily change coordinate projection systems in Python with pyproj - All-geo .

In 95% of your plotting, you allow_superseded (bool, default=False) Set to True to allow the use of superseded (but not deprecated) I got a step further with calculating the meshgrid from matlab, but the data are getting weird in cartopy, reproduced the same with basemap and it works just fine. How do I store enormous amounts of mechanical energy? Convert the projection to a JSON dictionary. This code demonstrates how to recover affine transformation as matrix + vector and tests that initial points are mapped to where they should. 584), Improving the developer experience in the energy sector, Starting the Prompt Design Site: A New Home in our Stack Exchange Neighborhood, Converting projected coordinates to lat/lon using Python, Error "latitude or longitude exceeded limits" when importing CSV file in QGIS, Using ogr to calculate distance is returning incorrect results away from equator. astropy.coordinates supports a rich system for transforming coordinates from one frame to another. interactively, you can see that changing the size of the figure does Click here proj_to (pyproj.Proj or input used to create one) Projection of output data.
