Topographic surveying involves the production of maps and plans which are true to scale. Topographic maps are produced to accurately represent details of both the natural and built environment. They will also include symbols representing features or data too small to produce to scale.
A Geographic Information System (GIS) is a system for capturing, storing, analyzing and managing data and associated attributes which are spatially referenced to the earth. In the strictest sense, it is a computer system capable of integrating, storing, editing, analyzing, sharing, and displaying geographically-referenced information.
Jers has in-house trained and highly productive staff that produces final Digital Base Maps using various field observations, remote sensing and satellite imagery techniques.
