I am trying to create a fishnet that is created orientated or built incorrectly. Why does the create fishnet do this?
I have the following code, but I am not sure why it's not creating it with the boundary of the input layer.
import arcpy
# Set the workspace (replace with the path to your data)
arcpy.env.workspace = r"C:\temp\Test.gdb"
# Input county PLSS grid feature class
county_plss_grid = r"C:\temp\Test.gdb\SEC_231N3W"
# Output grid feature class
output_grid = "SEC_231N3W_Grid_New2"
# Specify the coordinate system (NAD 1983 HARN StatePlane Oregon North FIPS 3601)
coordinate_system = arcpy.SpatialReference("NAD 1983 HARN StatePlane Oregon North FIPS 3601 (US Feet)")
# Get the extent of the county PLSS grid
extent = arcpy.Describe(county_plss_grid).extent
# Calculate the overall length and width of the input layer
length = extent.width
width = extent.height
# Determine the cell size based on the overall length and width
cell_size = min(length, width) / 10 # You can adjust the denominator for the desired number of cells
# Set the number of rows and columns
num_rows = 10
num_columns = 10
# Set the output coordinate system
arcpy.env.outputCoordinateSystem = coordinate_system
# Create a fishnet with 10 rows and 10 columns using the input layer width and height
fishnet_path = arcpy.management.CreateFishnet(
out_feature_class=output_grid,
origin_coord=f"{extent.XMin} {extent.YMin}",
y_axis_coord=f"{extent.XMin} {extent.YMin + cell_size}", # Move south to north
cell_width=cell_size,
cell_height=cell_size,
number_rows=num_rows,
number_columns=num_columns,
labels="NO_LABELS",
geometry_type="POLYGON",
template=county_plss_grid # Use the original shape as a template
)[0]
print(f"Fishnet created: {output_grid}")
