Add support for Gradio #362

Closed giswqs closed 1 year ago

giswqs commented 1 year ago

Gradio is a Python package for building interactive web apps to demo machine learning models. It supports bokeh and plotly. It would be great to add leafmap support for this.

A simple Gradio web app for visualizing COG with leafmap

import gradio as gr
import leafmap.plotlymap as leafmap

def create_map(url):
    m = leafmap.Map()
    m.add_cog_layer(url)
    return m   

url = 'https://opendata.digitalglobe.com/events/california-fire-2020/pre-event/2018-02-16/pine-gulch-fire20/1030010076004E00.tif'

demo = gr.Interface(
    fn=create_map,
    inputs=gr.Text(value=url, label='Enter a COG URL'),
    outputs=gr.Plot().style(),
)
demo.launch()

An Earthquake heatmap example.

import gradio as gr
import leafmap.plotlymap as leafmap

def create_map(url, latitude, longitude, z):
    m = leafmap.Map()
    m.add_heatmap(url, latitude, longitude, z)
    return m   

url = 'https://raw.githubusercontent.com/plotly/datasets/master/earthquakes-23k.csv'

demo = gr.Interface(
    fn=create_map,
    inputs=[gr.Text(value=url, label='Enter a URL'), 
            gr.Text(value='Latitude', label='Latitude column'), 
            gr.Text(value='Longitude', label='Longitude column'),
            gr.Text(value='Magnitude', label='Value column')],
    outputs=gr.Plot().style(),
)
demo.launch()
