3D of Elevation in Basemap ? /u/eidrisov Python Education

Hi everyone!

I have just discovered Basemap and I have a few questions:

1. Is it possible to actually build 3D design of the terrain in topological maps ? There is this example (see the code below) that allows elevations to be seen from above as a picture. What I am interested in is to see elevations not as a picture from above, but as a 3D objects, e.g. if I zoom in, I should be able to look at the mountain from the different sides as well as above.

   from mpl_toolkits.basemap import Basemap from mpl_toolkits.basemap import shiftgrid import matplotlib.pyplot as plt from osgeo import gdal import numpy as np

   map = Basemap(projection=’tmerc’, lat_0=0, lon_0=3, llcrnrlon=1.819757266426611, llcrnrlat=41.583851612359275, urcrnrlon=1.841589961763497, urcrnrlat=41.598674173123)

   ds = gdal.Open(“../sample_files/dem.tiff”) elevation = ds.ReadAsArray()

   map.imshow(plt.imread(‘../sample_files/orthophoto.jpg’))

   map.imshow(elevation, cmap = plt.get_cmap(‘terrain’), alpha = 0.5)

   plt.show()

2. Is it possible to save elevation maps created by RidgeMap as .obj, .f3d or .stl files later to import into Fusion 360 (or any other 3D design program) ?

Thanks in advance for any help!
