![]() It converts your data into contour maps, surface or volume plots. You can achieve a moderate level of detail in the contour lines because the DTM can have a resolution as high as five times the average ground sampling distance (GSD) of the project. 3DFieldPro is a contouring plotting and 4D-3D data program. The following steps download a DEM (30 m pixels) from the Shuttle Radar Topography Mission (SRTM) project and calculate contours. It creates a 3D map or a contour chart from the scattered points, numerical arrays or other. Generating contour lines with the digital surface model (DTM) is recommended when there are objects on the project's surface, such as high vegetation or buildings. 3DField converts your data into contour maps and surface plots. ![]() Locate your property on the Contour Map Creator website. You can achieve a high level of detail in the contour lines because the DSM can have a resolution as high as the average ground sampling distance (GSD) of the project.Ĭontour lines using the digital surface model How to create a topographic map in 10 minutes without expensive software or mapping skills STEP 1. It is intended to enable users to quickly make professional, statistical maps for. Generating contour lines with the digital surface model (DSM) is recommended when there are no objects on the project's surface, such as high vegetation or buildings. IMAGE is a web-based-tool used for the production of Choropleth Maps. The extent and highest resolution possible of the contour lines will depend on the source layer. Go next to Model Details, and use the Box Size slider to make the red box large enough to incorporate the feature you want. Navigate to the geographical area of interest by zooming and dragging, and click 'Center To View'. They give a better understanding of the variations in elevation of the land surface or topography of a project area.Ĭontour lines can be generated with the digital surface model (DSM) or the digital terrain model (DTM). You will be greeted by an interactive Google map. Contour lines are lines connecting points of equal elevation.
