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.
Animation and Dynamic Updates with KML. 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. The one big exception that I have used is the UK Ordnance Survey's Mastermap format which is based on GML.
Every single feature has a time stamp and version number, allowing feature changes to be documented over time. KML features can be animated using time stamps, time spans, and network (server) updates. Time Stamps Time Spans. David's Google Earth files. Google SketchUp. 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. It contains all of the elements that belong to Feature, and it adds some elements that are specific to the Placemark element. KML is an open standard officially named the OpenGIS® KML Encoding Standard (OGC KML). It is maintained by the Open Geospatial Consortium, Inc. (OGC). The complete XML schema for KML is located at Note: Click an element name in this diagram to jump to its entry in the reference section. Note that abstract elements (shown in boxes in the diagram) are not actually used in KML files.
All elements derived from Object can have an id assigned to them. Compatibility Syntax <! UUorld. Thematic Mapping Engine - thematicmapping.org. Using The KML Time Embedder, Concluded.

The Quarter/Quarter closest to our example position 39° 18' 40.58" N 102° 17' 30.47" W is the SE 1/4 of the NW 1/4 of Section 35, Range 44 West, Township 8 South, Sixth Meridian, Colorado. Verbose, forward and reversed SE 1/4 of the NW 1/4 of Section 35, Range 44 West, Township 8 South, Sixth Meridian, Colorado Colorado, Sixth Meridian, Township 8 South, Range 44 West, Section 35, SE 1/4 of the NW 1/4 Abbreviated, forward and reversed SENW 35 44W 8S 6th CO CO 6th 8S 44W 35 SENW If there is no possibility of duplication, the state or the meridian can be dropped.
In the above examples, both SENW 35 44W 8S 6th and SENW 35 44W 8S CO are both allowed. However, some states have more that one meridian, for example California has three. Likewise, a single meridian can cross into more than one state, causing duplication along the border. Excel2KML-Std Icon. Earth Outreach. Google Earth allows you to put your content into a geospatial context. More importantly, it allows you to tell stories.
In this tutorial, you'll learn some ways to make your content accessible, easier to navigate, and more compelling. The Google Earth Interface There are three main ways people will interact with your KML through the Google Earth interface: Places panel 3D map Your description balloons To design an immersive experience for people viewing your content, consider the most common path that visitors take. Here are examples of KMLs that provide an immersive, high-quality visitor experience: Make a Good First Impression The first thing most people see when they open a KML or KMZ file are the icons, models, image overlays, and polygons in the 3D view of Google Earth.
Take Snapshots of your placemarks. Setting a good default view for your placemarks and folders is one of the most important things you can do to ensure a good user experience. Don't overwhelm visitors. Use custom icons. Steven can plan – GIS and mapping tools. Some of the work I do for school and my job requires that I make maps. I’ve never taken a class on how to make maps or analyze data sets featured in maps (what GIS does), so I learn as I go. There’s no one around me I can call upon when I have questions that need immediate answers.
Well, there’s me! Because of this, I must quickly find a solution or workaround myself. Today I had to import a list of Chicago Transit Authority and Metra rail stations into ArcGIS so I could plot them on a map that also showed Chicago’s boundary and our bikeways. I could do this in Google Earth, but then I would have less control over the printed map I wanted to make, or the image output. That’s okay – what follows is how I overcame this barrier: Because I know how to use PHP to instantly create Keyhole Markup Language (KML) files (the format which Google Earth and Maps speaks fluently). Other tools I used to get my map created: Read about how I got around QGIS’s lack of geocoding.
