![]() In this article we will integrate ArcGIS and Google Earth to analyze building permit data for the City of Austin, Texas for the years 1997 to 2003. In the example below, the beginning time date is January 1st, 2003 and the ending time date is December 31st, 2003. The tag describes the beginning instant of a time period while the tag describes the ending instant of a time period. The TimeSpan tag represents an extent in time bounded by begin and end dates/times. Data that has been tagged with time information will appear or disappear depending on the current time of the map. Time properties including the time zone, animation speed, and other options can be set from this dialog. The user interface for the Timer control consists of a draggable area containing a start and end date which you can expand or shrink along with controls for starting the time animation and displaying the Time properties form. The Time control, which is both functional and minimal, is only visible on the Google Earth display when TimeSpan tags are detected in your kml/kmz file. In this how-to article you’ll discover how to create time enabled, Google Earth format files (kml/kmz) using a combination of ArcGIS Desktop, Spatial Analyst, Google Earth, and your favorite text editor.Ī new Time control has been added to the user interface which allows you to control the time period of the globe. The addition of this fourth dimension greatly enhances the capabilities of Google Earth by enabling you to analyze patterns in your data over time. ![]() The release of Google Earth 4 brought many new enhancements to an already fantastic geographic viewing tool, but in my opinion the most important new functionality is the introduction of the new Time control which allows you to incorporate time information into your existing GIS data. ![]() Filed under: Google Earth, Time Display | Creating Google Earth Time Display Data with ArcGIS ![]()
