In which documents are the angles from the Mexican Period recorded?

During the Mexican Period, field notes were meticulously used by surveyors to record various measurements and observations, including angles. These field notes served as the official account of the survey process and provided crucial data for understanding property boundaries and land divisions during this time. The notes typically documented the angles between property lines, distances, and the specific details of the land surveyed, which allowed for the accurate mapping and determination of ownership.

While grant records, survey maps, and property deeds contain valuable information regarding land ownership and borders, they do not specifically focus on the recorded angles used during measurements in the field. Grant records document the issuance of land grants, survey maps visually represent land parcels, and property deeds convey ownership rights but do not typically include the detailed surveying angles that are essential for understanding the surveying process itself. Thus, field notes are the primary documents that capture these specific angles during the Mexican Period.
