Likewise, the subsets can be created as sub KML files and the Region added to the NetworkLink in the master KML file with links to the sub KML files.įor more details, here's a tutorial on Regions in KMLįor large data, you can customize your KML adding Styles, Schemas, ExtendedData, descriptions, etc. If data is spread over a large geographic area then splitting the placemarks into Folders and adding a Region to the Folder can help auto-display a subset of the data at a time.
If data is temporal then add a or to each of the placemarks and add a element with a to the KML with a small time slice to show only a portion of the data at startup. Subset/group the points into multiple KML files splitting the data into whatever smaller groups make sense and view the data one KML file at time. If number of points is very large and still causes performance issues or crashes Google Earth Pro, here are three options to further structure the KML to make it work.
GOOGLE EARTH VERSUS GOOGLE EARTH PRO PRO
The GE Pro import wizard will create KML with BalloonStyle, Schema, and ExtendedData elements which works well for small datasets but creates problems for large ones. Google Earth Pro is an upgraded version of Google Earth that is meant for business oriented people. to streamline the KML output rather than try to import a large CSV or shapefile directly to Google Earth Pro. Recommend to create minimalized KML output using R or Python code, etc. The KML structure in image above is a series of simple placemarks. Google Earth Pro allows you fly anywhere around the earth to view satellite imagery, maps, 3D building, and terrain, from galaxies in outer space to the canyons of the ocean. Google Earth Pro can easily support display a KML file with 32,000 points or larger.īelow is a display of a KML file with 100,000 random placemarks spanning a strip over the ocean.
