# Pseudocode
# 1. Use an ArcGIS Pro Project with a template that includes:
#     - NAIP Imagery Layer
#     - CAFO Sites Layer
#     - Borderless layout from map
# 2. Set references to:
#     - Project
#     - map
#     - cafos_lyr
#     - layout
#     - Extents needed (python list?)
#     - Output images directory
# 3. Iterate on each cafos_lyr record. In the iteration, perform the following:
#     - Change the extent of the layout to the current site.
#     - For each scale needed:
#         - Set the camera scale to the scale
#         - Export to JPEG to the output images directory using formatting for naming

# aprx = arcpy.mp.ArcGISProject("CURRENT")
aprx = arcpy.mp.ArcGISProject(r"")  # Set path to your ArcGIS Pro Project

m = aprx.listMaps()[0]
cafos_lyr = m.listLayers("ky_afo_lonx_nonzero")[0]
cafos_lyr_id_field = "FID"
lyt = aprx.listLayouts()[0]
mf = lyt.listElements()[0]
output_dir = r""  # Set path to your output folder
cafos_scales_list = [1000, 2000, 3000]

# cafos_lyr_name = arcpy.GetParameterAsText(0)
# cafos_lyr_id_field = arcpy.GetParameterAsText(1)
