Aircraft Detection¶

Get Pleiades imagery for the given airports
Execute tiling and aircraft detection blocks via parallel jobs
Visualize the results
The example costs around 1700 UP42 credits

Setup¶

Import required libraries

In [14]:

import up42
import geopandas as gpd
import rasterio
from rasterio.plot import show
import matplotlib.pyplot as plt
from shapely.geometry import box

Configure areas of interest

In [15]:

Authenticate with UP42

In [16]:

#up42.authenticate(project_id="123", project_api_key="456")
up42.authenticate(cfg_file="config.json")
up42.settings(log=False)

2020-12-03 13:49:53,770 - Logging disabled - use up42.settings(log=True) to reactivate.

Catalog Search¶

Search cloudfree Pleiades image for the two aois and visualise the quicklooks.

In [17]:

catalog = up42.initialize_catalog()


for aoi in aois:
    print("\n---------" + aoi["title"] + "---------\n")
    search_paramaters = catalog.construct_parameters(geometry=aoi['geometry'],

    display(search_results.head())
    catalog.plot_quicklooks(figsize=(18,5), titles=search_results.scene_id.to_list())

    # Select least cloud scene for further workflow
    aoi["scene_id"] = search_results.scene_id.to_list()[0]
