The 1875 Carta General del Archipiélago Filipino (1902 U.S. edition) is a historical map of the Philippine archipelago originally prepared during the Spanish colonial period and later republished by the United States for administrative and military use.

According to the report, the map was produced under the direction of Capt. Claudio Montero, head of the Philippine Hydrographic Commission during the Spanish era, and was published in Madrid by the Dirección de Hidrografía, the Spanish government’s official charting office.

The map is described as one of the most complete and detailed official maps of Philippine territory during the Spanish regime. It shows the islands of the Philippine archipelago and surrounding waters with hydrographic information used for navigation.

One notable feature of the 1875 map is the inclusion of depth soundings across many islands and maritime features, including Scarborough Shoal and the Spratly Islands. These hydrographic details illustrate how the map documented maritime geography and navigational conditions in the region.

After the United States took control of the Philippines in 1898, the map continued to serve as an official territorial reference. The U.S. government adopted and reissued the 1875 map several times during the American colonial period, recognizing it as an official depiction of Philippine territory.

In the 1928 Islas Palmas arbitration case, the United States stated in its legal memorandum that the 1875 Carta General del Archipiélago Filipino “is both an American official and a Spanish official map” of Philippine territory.

Today, the map is frequently referenced in discussions of historical cartography and territorial documentation because it depicts the Philippine archipelago and surrounding maritime features as understood by official Spanish and later American authorities during the late nineteenth and early twentieth centuries.
