For DXF format you can also set the desired Coordinates Reference System by using EPSG code when exporting. In addition to making contours, this module is also equipped with contour editing tools such as edit vertex (move / add vertex), Smoothing (Cubic Bezier Interpolation) and reduce the number of vertex / Simplify (Douglas Peucker Algorithm).įurthermore, contour lines can be exported to CSV (XYZ), KML and DXF files. To display the elevation label, click on an existing contour and a menu will appear as follows:Ĭlick Show/Hide ELevation Labels then the height label will appear on each contour line as shown below. topoBuilder enables everyone to build custom, on-demand, topographic maps using reliable and authoritative National Map data. Make changes according to your needs then click OK, after the contours are created, click on the contour line to see the elevation values or click on contour polygon to see contour area / perimeter. Thanks to a highly successful pilot project, OnDemand Topo maps are now a permanent National Map offering and will continue to be provided on a free and unlimited basis. Open the module and click Contour button (bottom left) or tap anywhere on the maps to show contour dialog. It should be noted that the results are only for the purpose of visualizing the ground surface and not for precission mapping purposes. The process of making contour lines in our application is very simple, you only need to zoom the map to the desired location and the process of generating contours will be done automatically. The contour results can be exported to DXF or KML files. While other APPS are displaying contours from topo maps, we generate contours with configurable interval, using sophisticated GRID and TIN interpolation approaches which are also configurable and rich of options. This is premium modul & need internet connection. Then I thought, maybe you could get some use out of them too.Module to generate contours based on number of contour lines, desired elevation or contour interval. I originally built these maps because I wanted them to exist, for myself. I hike, bike, 4WD, paddle, ride, hunt, cross country ski, snowshoe and generally get out and about any chance I get. Sealed roads, unsealed roads, 4WD tracks, seasonal closure info, walking tracks, rivers, lakes and more, including satellite backing and hill-shading.Park boundaries and areas are all marked and kept up-to-date National Parks, state forest, state parks, reserves, sanctuaries, current mining leases and more.They include tens of thousands of Points Of Interest, including campsites, huts, mines, helipads, toilets, gates, jetties, boat ramps, fire towers, caves, fords, bridges, and lots more.Each update makes them better and do more. They’re up-to-date and still being updated all the time to keep them current, multiple times a year.They’re at 1:250,000, 1:75,000 and 1:25,000 depending on what you want, where you are and what you’re using them for.They’re topo maps – they include elevation contours (and depths).They cover all of Australia at various scales from 1:250,000 up to 1:25,000.
