Future versions may be harmonized with relevant OGC standards that comprise the OGC standards baseline. That there be one international standard language for expressing geographic annotation and visualization on existing or future web-based online and mobile maps (2d) and earth browsers (3d). The OGC has developed a broad Standards Baseline. KML is an XML language focused on geographic visualization, including annotation of maps and images. From this perspective, KML is complementary to most of the key existing OGC standards including GML (Geography Markup Language), WFS (Web Feature Service) and WMS (Web Map Service). 2) Downloads 3) Official Schemas

A Quick Tour of KML: Geographic Visualization for the Web | KML: An International Standard Just as web browsers read and display HTML files, Earth browsers such as Google Earth read and display KML files. Learn what KML is and how you can create a simple KML file yourself. After reading this chapter, you’ll be able to do the following: Give a simple definition of KML in layman’s terms. KML (Keyhole Markup Language) is an XML data format used to display information in a geographic context. As Michael T.
Using Google Earth Google LatLong Sky Data in KML - Keyhole Markup Language You can now create KML files that display objects in the sky, such as stars, constellations, planets, the Earth's moon, and galaxies. This page explains how to create a KML file to display celestial data in Google Sky. Specifically, you'll need to do the following: Add a hint attribute to the <kml> element at the beginning of your KML file that indicates the file contains sky data, not Earth data Convert celestial coordinates to Earth-based KML coordinates The Google Earth user can control when to switch to Sky mode, using the View > Switch to Sky menu option or the Sky button in the user interface. When the user switches to Sky mode, Google Earth transitions to show images of the sky photographed from telescopes around the world and inouter space. Coordinates Celestial coordinates are described in terms of right ascension (RA) and declination. Declination is analogous to latitude, with 0 degrees declination located at the celestial equator.

Google Earth Hacks blog The system we have been using for file comment was hand-built years ago, and really it was rather crude. To simplify things, we’ve just implemented the Comment system using the Facebook JavaScript SDK. This system looks nicer, and should be much easier to use. When viewing any file on the site, just scroll down and you’ll see the comment box. Here are a few examples of it on the site. Some test comments, so you can see how they look: When you post, you have the option to have the comment appear on your profile. If comments had been left for a file using the previous system, we’ve included a link to those so you can still view them: Lastly, we know that some of you don’t use Facebook and have no desire to, and that’s perfectly fine. So there you have it. Thanks! Mickey

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.
Google Maps Mania KML Reference - Keyhole Markup Language 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. KML is an open standard officially named the OpenGIS® KML Encoding Standard (OGC KML). 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. Because KML is an XML grammar and file format, tag names are case-sensitive and must appear exactly as shown here.
