A multi-resolution geographic data source.
<p>
<a class="el" href="a00633.html" title="A multi-resolution geographic data source.">vtkGeoSource</a> is an abstract superclass for all multi-resolution data sources shown in a geographic view like <a class="el" href="a00639.html" title="A 3D geospatial view.">vtkGeoView</a> or <a class="el" href="a00640.html" title="A 2D geospatial view.">vtkGeoView2D</a>. <a class="el" href="a00633.html" title="A multi-resolution geographic data source.">vtkGeoSource</a> subclasses need to implement the <a class="el" href="a00633.html#7bdffd5805c5df3bda0faab4aa01ba24">FetchRoot()</a> method, which fills a <a class="el" href="a00638.html">vtkGeoTreeNode</a> with the low-res data at the root, and <a class="el" href="a00633.html#028ad83c3540008edd7cf4f5b9c5c3e4">FetchChild()</a>, which produces a refinement of a parent node. Other geovis classes such as <a class="el" href="a00634.html" title="A 3D terrain model for the globe.">vtkGeoTerrain</a>, <a class="el" href="a00635.html" title="A 2D terrain model for the globe.">vtkGeoTerrain2D</a>, and <a class="el" href="a00611.html" title="Splits hi-res image into tiles.">vtkGeoAlignedImageSource</a> use a <a class="el" href="a00633.html" title="A multi-resolution geographic data source.">vtkGeoSource</a> subclass to build their geometry or image caches which are stored in trees. The source itself does not maintain the tree, but simply provides a mechanism for generating refined tree nodes.<p>
Sources are multi-threaded. Each source may have one or more worker threads associated with it, which this superclass manages. It is essential that the <a class="el" href="a00633.html#028ad83c3540008edd7cf4f5b9c5c3e4">FetchChild()</a> method is thread-safe, since it may be called from multiple workers simultaneously.<p>
