Using The KML Time Embedder, Concluded
Continuing on from the last post about the KML Time Embedder (download just the executable here , or the full install here ), a utility to embed time data into a KML file: Correct for local time zone : The default time zone for Google Earth times is UTC (aka Greenwich Mean Time), so a day runs from 00:00 to 23:59 UTC; you can set the time for your local time zone, but you have to know where to go in the time options to do this. For longer periods of time, the offset between local time and UTC might not make a difference. But if the time period is short, and the exact start and end of the day need to occur for the data’s local time zone, then check this box, and select the offset from UTC from the dropdown; this specifies the timezone for which the data is valid: Embed Time Information : Once you’ve set the input and output filenames, this control is enabled, but you’ll get an error message if you haven’t set a beginning or end time for TimeSpan, or a single time for TimeStamp.Although KML has quickly become the main format used for map annotation, it has a number of advanced features which only have limited support outside of Google Earth. Some of these absences are logical - for example, few mapping systems support 3d views and buildings. With the current pace of development it is likely that many of the other advanced features will be added to future versions of these products. One of the advanced features that will almost certainly see much wider support is that of animation. This article looks at KML's animation and dynamic update features. There are a lot of mapping formats in circulation, but few support the concept of time.

KML Reference - KML - Google Code
This section contains an alphabetical reference for all KML elements defined in KML Version 2.2, as well as elements in the Google extension namespace . The class tree for KML elements is shown below. In this diagram, elements to the right on a particular branch in the tree are extensions of the elements to their left. For example, Placemark is a special kind of Feature .Great explanations are unfortunately scarce, but UUorld makes them easier to achieve through interactive four-dimensional maps. Our solution has three simple parts: We think you'll find four-dimensional mapping delivers results because the medium exposes the spatial and temporal context inherent to nearly all data. Dear Friends, We’ve spent the last year involved in several interesting projects, gathering information on new uses of data visualization and collaborating with industry leaders to design UUorld 2.0 … and now we are pleased to announce that we’re starting its development! We’re going to build a new, better version of our software: we’ll upgrade our data ... continue reading » May 05, 2009
