When finished, a message box will report the filename location and number of polygons in the KML file.The number of polygons that are processed for the entire file extent is shown and the maximum count. As the file is generated, a status message will inform you of the progress.Press OK to generate a KMZ file to use in Google Earth.The default values for the output options are good suggestions.You can change the name and file location using the Browse button. The default name and location of the KMZ file (zipped up KML) will be based on the Plan that produced the inundation boundary.The 3D KML export dialog will be shown.Right-click on the Inundation Boundary layer and choose the Export Layer | Save Inundation to 3D KML menu option.Set the symbology to the color and transparency (blue, 50% are good values).To create a 3D KML, perform the following steps listed below. Therefore, you may consider filtering the inundation boundary polygon, prior to KML export.Īn example inundation KML in Google Earth is shown below. The KML can then be added to a Google Earth instance (or likely you can double-click on the KML and it will launch and load Google Earth).Įxperience has shown, that KML files with more that 10,000 points do not render well in Google Earth.Right-click on the Inundation Boundary layer and choose the Export Layer | Save Features to KML menu option.Create and Inundation Boundary layer in RAS Mapper.To create a KML, perform the following steps listed below. Provided you have an inundation boundary polygon developed in HEC-RAS, you can export it either to a KML file or to a 3D KML by simply right-clicking on the inundation boundary polygon and selecting the Export Layer menu option. HEC-RAS has two different ways to create inundation maps using the KML format specific to Google Earth. Google Earth, however, is a powerful visualization tool that can be used to display inundation boundary maps. While users can display background imagery using web services in HEC-RAS, it is often not the best way to avail to the results to non-RAS users. Then click on ArcGIS Earth option to download/save the kmz file.HEC-RAS inundation maps are able to tell a complex story of the flooding potential in our river floodplains. Click on a map service of interest - it will open in a new tab. Here you’ll see a list of available map services. If you are using Google Earth Pro then I assume that you already have it installed on your machine. 2020) but not the older Edge Legacy browser. 73.0.1) and the new Microsoft Edge browser (released Jan. Google Earth Web also works with Firefox (v. ![]() ![]() The Google Earth Web is of course the browser version and works best in Chrome. This is a short post on how to bring in ESRI basemaps in Google Earth Pro (desktop) and Google Earth Web. Many people are familiar with Google Earth and want to have other basemap options to use. Did you know you can view/use ESRI basemaps in Google Earth Web and Pro? I had forgotten about ESRI’s KML/KMZ map service capabilities until someone asked me if it was possible to use/view USGS topo maps in Google Earth.
