In the context of the current discussion about Copernicus services for cultural heritage integrating imagery from the Sentinels with those from contributing missions, such as the Italian Space Agency (ASI)’s X-band SAR constellation COSMO-SkyMed, we explore benefits and limitations of a multi-technique and multi-platform approach of change detection for heritage conservation. We prove the concept in selected heritage sites across the globe, with regard to: (i) anthropogenic disturbance, and (ii) urban sprawl. In Nasca, Peru, a systematic COSMO-SkyMed StripMap time series at 3-m resolution allowed precise identification of the extent of damage caused by a truck that accidentally crossed over three linear geoglyphs in early 2018, that Sentinel-2 could barely capture at 10-m. On the other hand, in Cyrenaica, Libya, Sentinel-2 proved effective to screen wider regions and undertake comparative condition assessment of sites impacted by unregulated urbanization across the landscape.
