In this tutorial, we will learn how to adjust the contour intervals using SketchUp. Technically, it is possible to label the elevation of each contour line more extensively up to 5 meters (or less) through 3-D modelling. Topographic maps may have many contour lines. These topographic elevations found mostly on online map can only be viewed in a macro scale level, showing a minimum of 20m contour intervals. Most contour lines found in online topographic maps such as Google map ( ), Open Street Maps ( ), NAMRIA ( ), etc. Modelling and reading topographic maps becomes more convenient with the aid of modern technology such as online map surveying and 3-D modelling software.
