Abstract:Considering topographic map is a basic material of planning and design in Civil and Hydraulic engineering. A method of making contour map without compromising the precision was proposed by extracting elevation data based on Google Earth by programming and generating contours using ArcGIS. Meanwhile it indicates specific means of contours optimization and coordinate system conversion. By analyzing and comparing the topographic map accuracy with an example, the result shows the method is feasible and has reasonable application value.
