DavidJPotter Posted March 25, 2022 Share Posted March 25, 2022 Is our only alternative to hire a surveyor to obtain, clear, legible contour lines for creating a realistic terrain plane? DJP Link to comment Share on other sites More sharing options...

CJSpud Posted March 25, 2022 Share Posted March 25, 2022 I have found USGS maps on line with contours for the areas where some of my projects were located. Unfortunately, there are no elevations data bases the way I've used those maps. I just rescale them as best I can and then recreate the elevation contours using elevation lines and points. Keep in mind that unless you can get a 7.5 minute map, the contour intervals are large. If the area is not very steep, this method is more or less useless, especially if the property isn't very big.

JiAngelo Posted March 28, 2022 Share Posted March 28, 2022 In Ohio several county auditors provide this data for download. In our home county they have parcel data and gis data in separate files. We can download both and import them to give us the topography and lot lines. I searched Austin Texas and found you can download DWG files of the data at https://austintexas.app.box.com/s/nu5ju1ni2vz0oonm67f014xqdwip526k/folder/42061586880 Here's the main website https://www.austintexas.gov/department/gis-data It includes some arcgis links which we also find useful. Hope this helps. 1 1 Link to comment Share on other sites More sharing options...
