This lecture will use Jupyter notebooks with Python to read, calculate, and visualize GOES-16 GOES Rebroadcast (GRB) feed data that is accessed from a THREDDS data server. set_zorder(2). crs as ccrs ax = plt. basemap import Basemap # create north polar stereographic basemap m = Basemap (lon_0 = 270, boundinglat = 20, projection = 'npstere', round = True) #m = Basemap(lon_0=-105,lat_0=40. add_feature(cfeature. The pre-defined Features are all small-scale (1:110m) Natural Earth datasets, and can be added with methods such as GeoAxes. Here the throughput was 5. colorbar ();. Cartopy, Basemap: map overlay on NOAA APT image I am working on a project trying to decode NOAA APT images, so far I reached the stage where I can get the images from raw IQ recordings from RTLSDRs. A granule is a subset of a swath consisting of 48 scans of the VIIRS instrument. None of these examples make use of xarray’s builtin plotting functions, since additional work is most likely needed to extend xarray in order to work correctly. pyplot as plt import cartopy.

You might also be interested in the field::geography debtag and, depending on your focus, in the education-geography metapackage. Plotting with salem¶. add_feature ax. It will let you process geospatial data, analyze it, and produce maps. 15 The cartopy is a great tool for creating maps in many ways more advanced than the usual workhorse for map creation in pyhton - the Basemap module.
