The District’s Surveying & Mapping Division is comprised of approximately 40 employees and provides information and assistance to the public and District personnel through the following sections:
This section utilizes advanced GPS technology and highly accurate field survey methods to meet the ever growing demands of the District in relation to design, construction, boundary determination and photogrammetric mapping needs.
pho∙to∙gram∙me∙try \fōt-e-gram-e-trē: is the art, science, and technology of obtaining reliable information about physical objects and the environment through processes of recording, measuring, and interpreting photographic images and patterns of electromagnetic radiant energy and other phenomena.
The photogrammetry section has a rich history in providing aerial mapping to the District engineers beginning in 1957. The section has gone through many types of instrumentation from optical projection to mechanical projection to analytical stereo plotters to the present platform of Digital Photogrammetric Workstations.
