IdentifierMaps_197aDate1807DescriptionAccording to Streeter, Bibliography, no. 1041: "This chart, showing the northern coast line of the Gulf of Mexico beginning at Cape San Blas on the Gulf Coast of Florida and extending as far as 24" 15' on the Mexican coast, follows with slight changes and on a larger scale the Carta Esferica of 1799" (Streeter, Bibliography, no. 1029; Lowery, no. 721).

The Carta Esferica was the most advanced depiction of the Texas coast, when it appeared in 1799, and it remained the foundation map for the region until the beginning of the Anglo-American settlement in the 1820s. It shows a crudely conceived Galveston Bay, based on the survey conducted by the Spanish navigator Jose de Evia from 1783 to 1786. Bernardo de Galvez, viceroy of New Spain, ordered the survey, and the bay was named in his honor. No contemporary printed chart showing the results of Evia's reconnaissance exists, as the Direccion Hidrografica (Spanish Admirality) began issuing charts only in 1797 or 1798.

From the Texas point of view, this Carta particular of 1807 is an improvement in one respect over the Carta Esferica. As it omits the easternmost ten degrees of longitude of the latter map, the Carta particular shows Texas on a larger scale. In addition, the Trinity River is correctly named on this map, whereas it is called "Archisas" on the Carta Esferica. The Brazos is absent from both maps.
