Creating a fishnet based on an input vector dataset

Uncomment the following line to install geemap if needed.

# !pip install -U geemap

import ee
import geemap

Map = geemap.Map()
Map

Simply draw a rectangle or polyon on the map use to used as an ROI.

data = Map.user_roi

if data is None:
    data = ee.Geometry.BBox(-112.8089, 33.7306, -88.5951, 46.6244)
    Map.addLayer(data, {}, "ROI")
    Map.user_roi = None

Map.centerObject(data)

The input data can also be a file path or HTTP URL to a vector dataset. There are two ways to create a fishnet: specifying horizontal and vertical intervals or the number of rows and columns.

Let's create a fishnet by specifying horizontal and vertical intervals in degrees.

fishnet = geemap.fishnet(data, h_interval=2.0, v_interval=2.0, delta=1)

Map.addLayer(fishnet, {}, "Fishnet 1")

Draw another polygon on the map.

data = Map.user_roi

if data is None:
    data = ee.Geometry.Polygon(
        [
            [
                [-64.602356, -1.127399],
                [-68.821106, -12.625598],
                [-60.647278, -22.498601],
                [-47.815247, -21.111406],
                [-43.860168, -8.913564],
                [-54.582825, -0.775886],
                [-60.823059, 0.454555],
                [-64.602356, -1.127399],
            ]
        ]
    )
    Map.addLayer(data, {}, "ROI2")

Map.centerObject(data)
Map

Let's create another fishnet by specifying the number of rows and columns.

fishnet = geemap.fishnet(data, rows=6, cols=8, delta=1)

Map.addLayer(fishnet, {}, "Fishnet 2")
