 In spite of the forty year Italian relationship with the sultanates, Italy did not have adequate knowledge of the geography.During this time, the Stefanini-Puccioni geological survey was scheduled to take place, so it was a good opportunity for the expedition of Coronaro to join with this.Coronaro's survey concluded that the Ismaan Sultanate depended on sea traffic, therefore, if this were blocked any resistance which could be mounted came after the invasion of the sultanate would be minimal.
