![]() ![]() NASA World Wind is geobrowser core technology that provides the infrastructure for spatial data as a Software Development Kit (SDK). This webinar will be on "NASA World Wind Virtual Globe Technology" and also on the Europa Challenge, by: Patrick Hogan, NASA World Wind Project Manager, received his BSc in Geology at University of California, Santa Cruz, and his MSc in Geology at San Jose State and Maria Antonia Brovelli, Professor of GIS at Politecnico di Milano, has a degree with honours in Physics and a PhD in Geodesy. The webinars will be open and free to all on first come register basis. The ICA-OSGeo Lab Network and MundoGEO are now pleased to inform the fourth webinar of the ”Open Geospatial Science & Applications” webinar series on February 13rd. See the NominatimGeocoder API doc to determine the details of the returned results and the accepted query string parameters.LatinAmerica | | Webinars | Aboutġ7h - 18h | World Wind Virtual Globe Technology An example of doing this is in LayerManager.js. These coordinates can be passed to a GoToAnimator to move the navigator smoothly to that geographic position. Two important properties of each result are its lat and lon properties, which identify the latitude and longitude of the place. More than one place may be identified each is represented by an element in the return array. The results are parsed JSON and contain a wealth of information about the places found that match the query string. The arguments to the callback function are, in order, a reference to geocoder and an array of query results. The callback function is called when the service replies. The query string is sent to the geocoder service. The arguments to this function are a query string and a callback function. The NominatimGeocoder has one function, lookup. An example of its usage is in LayerManager.js. Web WorldWind provides the NominatimGeocoder that uses Open Street Map’s Nominatim geocoder at MapQuest. Geocoders convert query strings identifying places to geographic locations and other useful information. You can change the time it takes to perform the animation via the travelTime property. Use a Position if you want the end position to have a different altitude than the start position. Use a Location if you want the start and end positions to have the same altitude. To use this class you pass its goTo function either a Location or a Position. You can see example usage in LayerManager.js. To change the navigator smoothly, use the GoToAnimator class. roll - The navigator’s angle around an imaginary line from the eye position to the look-at location.A value of 0 points the user straight down on the globe. ![]() tilt - The navigator’s tilt, in degrees.heading - The navigator’s heading, in degrees clockwise from north.The navigator also has the following properties that the app can set: For that use a GoToAnimator, described below. Ideally the view would change incrementally and smoothly. = 2e6 // 2 million meters above the ellipsoid Adjust the Navigator to place Alaska in the center of the range - Indicates the eye distance from the globe’s ellipsoid.īy specifying these properties the app can move the user to any point around the globe, as in this example: // Get a reference to the WorldWindow. ![]()
