TOPOGRAPHIC SURVEYS
The reason for a TOPOGRAPHIC SURVEYis to accumulate study information about the regular andman-made elements of the area, and itselevations. From this data a three-dimensional guide might be readied. You mayprepare the topographic guide in the workplace aftercollecting the field information or set it up right awayin the field via plane table. The work usuallyconsists of the following:1. Setting up even and vertical controlthat will serve as the system of the survey2. Sufficiently deciding level locationand rise (generally called side shots) of groundpoints to give enough information to plotting whenthe guide is prepared3. Finding characteristic and man-made featuresthat might be required by the reason for the survey4. Figuring separations, edges, andelevations5. Drawing the topographic mapTopographic studies are generally identifiedwith even and/or vertical control of third-and lower-request accuracies.ROUTE SURVEYSThe term course study alludes to surveysnecessary for the area and development oflines of transportation or correspondence thatcontinue crosswise over nation for some separation, suchas roadways, railways, open-conductor systems,pipelines, and electrical cables. For the most part, the pre-liminary study for this work takes the structure ofa topographic study. In the last stage, the workmay comprise
