In the Catalog window, navigate to System Toolboxes > 3D Analyst Tools > Conversion > From File > ASCII 3D to Feature Class. Select POINT as the output feature class type.Specify the location of the output feature class.The KML, KMZ, and GPX files are beforehand in the WGS84 geographic system (Longitude-Latitude) in this case, on the left, we keep WGS 84, and on the right we select the output system for example: UTM, Lambert, RGF93, If the file to convert is in. A new point feature is created.įor more information on how to use the ASCII 3D To Feature Class tool, refer to the following ArcGIS Web Help page: ASCII 3D to Feature Class. Use one of the surface interpolation methods such as IDW, Kriging, Natural Neighbor, and Spline to create a DEM. For more information on the available interpolation methods in ArcMap, refer to the following ArcGIS Web Help page: Comparing interpolation methods. This tool will convert an ASCII text file containing X,Y,Z point data into a raster image.The simplest method, using Spline is outlined below. Navigate to System Toolboxes > 3D Analyst Tools > Raster Interpolation > Spline.

The user must specify the names of the text file containing the point data, a base raster image, and the output raster name. Specify the location of the output raster.įor more information on how to use the Spline tool, refer to the following ArcGIS Web Help page: Spline.Select the Shape field as the Z value field.Select the point features for the input.The point data in the text file must be delimited using either tabs, spaces, or commas. Specify the output of the polyline features.Navigate to System Toolboxes Raster Surface > Surface.Use the Contour tool to create a contour from the DEM.
