Online Tilesets: Google Maps tilesets prepared in TNTmips
Your maps and images can be quickly displayed in a browser
from your web pages using Google Maps. For this use your rasters must be processed into the strictly-defined Google
Maps tileset structure and referenced by suitable HTML files that overlay these tilesets and the desired gadgets on the
base layers from Google Maps.
Your maps and images can be overlaid in your local Google Earth application or in the Google Earth browser plugin as temporary layers if they are referenced by a KML file. This KML file can be distributed for local use or accessed directly from your site's web pages. The actual map and image content of the layer can also be distributed or can be accessed remotely from your web site. For fastest operation in Google Earth, large high-resolution layers should be in Google Earth's tileset structure. Tiles can be PNG, JPEG, or TIFF files and can vary in size, typically within the range of 256 by 256 pixels to 2048 by 2048 pixels. The optimal tile size depends on display board limits and whether the tileset is for local or web use. Tiles do not have to conform to a predetermined grid on the Earth but must use Latitude / Longitude coordinates (WGS84 / Geographic coordinate reference system). The TNTmips Auto Mosaic process can build these tilesets from a very large collection of input rasters and create the required KML file.
