Pierre Jacotin

Pierre Jacotin (1765–1827) was the director of the survey for the Carte de l'Égypte (Description de l'Égypte), the first triangulation-based map of Egypt, Syria and Palestine.

Jacotin's 1799 survey of Egypt and Palestine, as a composite, published in 1818 (Carte geographique de l'Egypte et des pays environnans. Reduite d'apres la Carte topographique levee pendant l'expedition de l'Armee francaise)

The maps were surveyed in 1799-1800 during the campaign in Egypt and Palestine of Napoleon.

After his return from Egypt, Jacotin worked on preparing the plates for publication, but in 1808 Napoleon formally made them state secrets and forbade publication. This was apparently connected with Napoleon's efforts at the time to establish an alliance with the Ottomans.

It was not until 1828-30 that the engraved plates could be published.[1]
