![]() AutoPlotter gives flexibility to edit the surface itself which can be useful for more precise works. Include / Exclude boundary option along with breaklines give user all the required control to generate contour map in such a way that it represents the actual ground to the closest.Īll the functionalities are carried out based on DTM surface that is created after survey data is imported. Sometimes, it is required to limit the cad contour lines within a boundary or to draw the contours outside the boundary. Apart from the usual way to label the contours at end or along the path, in AutoPlotter contours can even be annotated at line intersections and at selected locations on contour. Smooth contour can be obtained by selecting the most appropriate equation.ģd contour lines can be labelled to display contour level so that the contour lines map is easily read and visualized. Contours can be generated in different drawing layers as per the type of definition. It is possible to assign different linetypes for the contours. In this CAD application software, properties of the contour lines can be set to meet various functional requirements. Apart from these two types, it is possible to define individual contour elevation lines for the given RL. That means, for the entire survey data, multiple elevation ranges can be defined for easy identification of ground profile on terrain maps. Similar maps at varying scales were produced during the same time period for Alaska, Hawaii, and US Territories. From approximately 1947 to 1992, more than 55,000 7.5-minute maps were made to cover the 48 conterminous states. The second type of definition is based on range of elevations. The best known USGS maps are the 1:24,000-scale topographic maps, also known as 7.5-minute quadrangles. Each group can be displayed with different colours. One or more groups can be defined as per contour interval on topographic map. An easy contour map software#The software displays the starting RL from the elevation data. The first one is based on contour interval definition. In this contour generation software, there are 3 types of definition. This is a useful method because it is easy for people to. Final CAD drawing can be saved into any standard cad application format, or it can be directly printed if required. The earliest maps depicted terrain as drawings of hills and mountains. Place a screenshot of the Google Earth view of the site. Accurate contour generation can be useful to realize the current terrain condition and to plan the future development activities.ĪutoPlotter is a CAD software that can easily create a contour map in which contour interval is given by the user. Open a new gCADPlus drawing (without using a template) and save it. Land Surveyors and Civil Engineers know the importance of topographic contour map during construction project planning and execution. Contour lines represent the nature of ground in 3d map format. ![]()
