anyone know a work around for this or is it a case of waiting for him to fix it?

Hi,
Had the same problem when using blender 4.1 because they changed a few things. I looked into it and changed a few things for myself in a file named: nodes_terrain_analysis_builder.py

I have pasted what I changed and you can try it for yourself.

Copy and paste this between lines 59 & 77 in your file located:

C:\Users\You\AppData\Roaming\Blender Foundation\Blender\4.1\scripts\addons\BlenderGIS-master\operators.

Make a copy of the original just in case.

#groupsTree.remove(groupsTree['Normalize'])
			scaleNodesGroupTree = groupsTree['Normalize']
			scaleNodesGroupTree.nodes.clear()
			scaleNodesGroupTree.interface.clear()
		else:
			scaleNodesGroupTree = groupsTree.new('Normalize', 'ShaderNodeTree') # = bpy.types.node_tree
		scaleNodesGroupName = scaleNodesGroupTree.name #Normalize.001 if normalize already exists
		#  group inputs
		scaleInputsNode = scaleNodesGroupTree.nodes.new('NodeGroupInput')
		scaleInputsNode.location = (-350,0)
		scaleNodesGroupTree.interface.new_socket(name='val', in_out='INPUT', socket_type='NodeSocketFloat')
		scaleNodesGroupTree.interface.new_socket(name='min', in_out='INPUT', socket_type='NodeSocketFloat')
		scaleNodesGroupTree.interface.new_socket(name='max', in_out='INPUT', socket_type='NodeSocketFloat')
		#  group outputs
		scaleOutputsNode = scaleNodesGroupTree.nodes.new('NodeGroupOutput')
		scaleOutputsNode.location = (300,0)
		scaleNodesGroupTree.interface.new_socket(name='val', in_out='OUTPUT', socket_type='NodeSocketFloat')

Hope it works for you!
