In this module we will demonstrate the basic use of KML in QGIS and a few tricks that will make it possible to store attributes (in a separate spreadsheet) and join them to the correct spatial features.Ī quick search for KML of Egypt found some layers of Egyptian Pyramids. However, there are some particular aspects of the KML notation that make it less than optimal for data entry, especially for the annotation of spatial features (aka "placemarks") with attributes, as we expect to do in GIS. Since KML files can be created using the free (and relatively easy to use) Google Earth software, it has become quite popular. ![]() The KML technology was purchased by Google in 2004, and became the main format used by the Google Earth application. In our exercise, we will prefer the KML format, which we can view and manipulate as needed. KMZ is a compressed version of the KML to save disk space and transfer time. ![]() ![]() KML is a "flat text" format which can be read and edited with an ordinary text editor. KML and KMZ files ( Keyhole Markup Language) are stored in an XML notation designed for visualizing and annotating geographic information.
