from shapely.geometry import Point

The layout consists of 96 geophones with a spacing of 2.5m. The first geophone is at station 0.

The spacing between shot points is 12.5 m. The first shot is at station -45 and the mast one is at station 140.

Create shots using the station as name

shots = [TopoPoint(Point(i*2.5,0), id=f'{i}', kind='shot') for i in range(-45, 145, 5)]

Create geophones using the station as name every two geophones

geophones = [TopoPoint(Point(i*2.5,0), id=f'{i}' if i%2 == 0 else '', kind='geophone') for i in range(0, 96)]

Create the layout

layout = shots
layout.extend(geophones)

Convert the features in the layout into a geodataframe

gdf_layout = features_to_gdf(layout)
gdf_layout.head()

	geometry	id	label	kind	class
0	POINT (-112.50000 0.00000)	-45	-45	shot	TopoPoint
1	POINT (-100.00000 0.00000)	-40	-40	shot	TopoPoint
2	POINT (-87.50000 0.00000)	-35	-35	shot	TopoPoint
3	POINT (-75.00000 0.00000)	-30	-30	shot	TopoPoint
4	POINT (-62.50000 0.00000)	-25	-25	shot	TopoPoint

Plot the layout

fig, ax = plt.subplots(figsize=(30,10))
plot_gdf_survey(gdf_layout, ax=ax);
