Create DEM & Contour From Google Earth in ArcGIS

In this Tutorial learn, how to Create Contour and DEM (Digital Elevation Models) from Google Earth with to help of ArcGIS Software.

Digital Elevation Model (DEM) is an Elevation data to represent Terrain.

Create DEM from Google Earth

DEMs are used often in Geographic Information Systems (GIS) and are the most common basis for digitally-produced relief maps as well as surface modeling.

You can creating a DEM data using both, Google Earth Pro and Google Earth Web.

Create DEM Using Google Earth Pro

Open Google Earth pro application.

DEM from google earth

Google Earth is open to select any area or search for any particular region (choose hilly region).
Now Add Path and create poly-line or path Data. Write the File Name (path) and click OK.

create path

The next step is to save your data. Right-click Path and select Save Place As. Choose Data Format KML.

Create DEM Using Google Earth Web

Open Google Earth web.

In the Menu bar, click Add menu, and choose Polygon (the polygon tool also used to polyline).

Now create a path in the map, same as Google Earth pro desktop.

Once you have create a path, now Save your data into KML format.

Click three dot on your project name’s, and select Export as KML file.

Convert KML to GPX

In the next part, KML Data convert to GPX Data to help from GPX Visualizer site.

Open GPS Visualizer Elevation, Browse KML File (path.klm), then convert & add elevation Output select GPX file.

Convert GPX to Feature using ArcGIS

Finally, open ArcGIS Software and add the GPX Data to Feature.

In the Search Box Search GPX to features, or you can also manually open this Tool. Open ArcTollbox, in the Conversion Tools group select From GPS subgroup and open GPX to Features Tool.

GPX to Features window appears, select Input GPX File (path.gpx) and also Output Feature Class then click OK button.

Now add GPX Feature Data (path_feature) in ArcMap.

Create IDW/DEM

Create a DEM to open IDW Tool.

In the search box, search IDW. or you can also manually open this Tool. Open ArcTollbox, in the Spatial Analyst Tools group Select Interpolation subgroup and Open IDW Tool.

IDW Tool window appears, select Input point features (path_feature). The most Important Z value filed select Elevation, and choose output raster Destination. Finally, click the OK button.

Add IDW in Table of Contents, and show the DEM result.

create DEM or IDW

Right-click IDW, select Properties. Layer Properties window appears in the Symbology group, Choose Stretched and click OK.

Create Contour from DEM Data

Now you can easily Create a Contour Map to from this DEM Data using IDW method.
