Define geohash data¶

In [ ]:

# Sample geohash data (around San Francisco area, precision 5)
geohash_data = [
    {"geohash": "9q8yy", "value": 150},
    {"geohash": "9q8yz", "value": 200},
    {"geohash": "9q8yv", "value": 180},
    {"geohash": "9q8yw", "value": 250},
    {"geohash": "9q8yx", "value": 300},
    {"geohash": "9q8yu", "value": 220},
    {"geohash": "9q8yt", "value": 190},
    {"geohash": "9q8ys", "value": 280},
    {"geohash": "9q8yr", "value": 170},
    {"geohash": "9q8yq", "value": 230},
]

# Sample geohash data (around San Francisco area, precision 5) geohash_data = [ {"geohash": "9q8yy", "value": 150}, {"geohash": "9q8yz", "value": 200}, {"geohash": "9q8yv", "value": 180}, {"geohash": "9q8yw", "value": 250}, {"geohash": "9q8yx", "value": 300}, {"geohash": "9q8yu", "value": 220}, {"geohash": "9q8yt", "value": 190}, {"geohash": "9q8ys", "value": 280}, {"geohash": "9q8yr", "value": 170}, {"geohash": "9q8yq", "value": 230}, ]

Create map with geohash layer¶

In [ ]:

m = DeckGLMap(center=[-122.4, 37.75], zoom=10, pitch=45)
m.add_basemap("CartoDB.DarkMatter")

m.add_geohash_layer(
    data=geohash_data,
    get_geohash="geohash",
    get_fill_color=[100, 200, 100, 180],
    get_elevation="value",
    extruded=True,
    elevation_scale=100,
    pickable=True,
)
m

m = DeckGLMap(center=[-122.4, 37.75], zoom=10, pitch=45) m.add_basemap("CartoDB.DarkMatter") m.add_geohash_layer( data=geohash_data, get_geohash="geohash", get_fill_color=[100, 200, 100, 180], get_elevation="value", extruded=True, elevation_scale=100, pickable=True, ) m

Export to HTML¶

m.to_html("geohash_layer_example.html")
