INTREPID User Manual Survey distance calculation T10 1 Library Help Top lt 4 Back gt Survey distance calculation T10 Top The Survey Distance Calculator calculates the total distance travelled in one or more surveys based on the flight data recorded You can use the results for accounting purposes You can choose which parts of the surveys to include in the calculation according to survey flight and traverse line numbers INTREPID will graphically display flight paths of the selected data if required You can choose whether to calculate the distance accurately from point to point or assume that each traverse line is approximately straight and use the end points of the traverse lines If you are processing unprojected data data with geographical coordinates latitude and longitude you can specify the average height of the survey above the datum for the purposes of the calculation Projections and measurement units Library Help Top If the data is projected INTREPID assumes that it has already been transformed into a suitable coordinate system with distances in metres It therefore does not transform the input data and calculates distances by simply integrating along each individual traverse line The resultant distances will naturally depend on the projection used If the data 1s unprojected INTREPID assumes that its location data has geographic coordinates latitude and longitude relative to the AGD84 datu
