The first thing to do is to look for pre-filtered data on Jonathan de Ferranti's web site. This is why, you may want in some cases, to download pre-filtered data or to use a dedicated program to filter terrain data in a smarter way. However this does not always give perfect results.
Tacview is doing its best by filling holes using the available low-resolution ETOPO1 data. It is also very easy to download and install additional EECH and real-life terrains: Just have a look in the add-ons section! Custom Texture Tilesīecause of the radar technique used during Shuttle Radar Topography Mission, canyons and mountains can contain quite a lot of holes. Falcon 4 theaters are also natively supported, and new ones can be integrated in just a few minutes by adding a declaration in the appropriate. Or you can force a specific layer set by using the appropriate option. You can let Tacview automatically choose the most appropriate layer set according to the flight data source. If no SRTM3 tile is available, it falls back on the default low-res ETOPO1 base map. For example: When a required hi-res SRTM1 tile is not available, Tacview tries to display the corresponding med-res SRTM3 tile. From the lowest resolution ( ETOPO1) to the highest resolution ( SRTM1), Tacview engine automatically displays the most appropriate level of detail depending on current zoom level and data available. The terrain of Tacview is made of layers. Like Google Earth, Tacview is able to display the earth in its whole like it is in real life! Unlike many flight simulators, Tacview does not try to project a spherical terrain on a flat surface.
