The 21.1 release of Spatial Studio supports KML file upload. KML is a file format based on XML for storing geographic data and associated content, and it is an Open Geospatial Consortium (OGC) standard. KML is often used to share data over the Internet for visualization. You can also upload a KMZ file, which is a zipped KML file.
KML file may have zero, one, or many folders. In this release, nested folders are not supported, so folders must all be at the root level. One folder is uploaded into one database table. This folder may only have one type of geometry. If there are no folders, then all valid Placemarks are also uploaded into one database table.
Follow these steps to upload a KML file.
Certain requirements must be met for a KML upload to Spatial Studio. For example, a dataset can only contain one geometry type, such as Point or Polygon. Details are in the Notes section.
As shown below, click on the KML upload button, then click on the KML file that you want to upload. A dialog menu will open. A KML file can contain multiple folders, so there may be multiple popup windows.
Choose your connection for the dataset upload from the drop-down list. Default values are provided for the table name and dataset name for each folder. You may keep the default names or modify them.
Below is a screenshot of an upload of the first folder of a KML file that contains three folders.
After a folder is uploaded, a dataset is created. Right click on the dataset to create a Project. You are now ready to visualize your data and perform spatial analysis!
Currently KML upload has the following constraints:
