Like these..?
If so they are aerial marker posts for national oil and fuel supply pipelines- to enable periodically surveying of pipe routes- this is often done by helicopter. I used to work in highway utilities and the authorities / oil cos are very protective of them- hardly surprising when some of the lines are large diameter and very high pressure.
