This article mainly shows you the "sample analysis of mpt in the secondary development of TE", which is easy to understand and well-organized. I hope it can help you solve your doubts. Let the editor lead you to study and study the "sample analysis of mpt in the secondary development of TE".

When doing te development, the most basic thing is to add a mpt, without mpt or online mpt, you can't even open a project, let alone do anything else.

As commercial software, some formats must be limited, and not very conspicuous to be seen, can not be like cesium, find a commonly used map slice to load, so local time, only TE can open mpt, online, only with other people's gate or sgs, can release mpt,TE can be opened in the client, but other software must be like this, only in this way can a series of commercialization.

Mpt format is essentially a large slicing group, just like common two-dimensional map slices, however, other people's commercialization, certainly can not let you see how the slices are organized, how to arrange, otherwise, you can also get a mpt reader, release mpt, then, what linux gate can have, but also afraid that foreigners do not develop this, do not develop that.

When making mpt from tb, you can see that the slice is also cut out according to the level, cut out the image and elevation, and store it in the so-called .mpt file, the high-score image corresponds to the high-level two-dimensional map slice, which must also be cut slowly, and the middle of the slice has also been optimized, otherwise the display speed is so smooth, this is also the massive data mentioned by skyline at the beginning.

The pyramid of arcgis also makes a bunch of temporary slices of the image. There are also pyramids in skyline. When tb does mpt, it can recognize the pyramids in arcgis, turn the pyramid files into the pyramids of skyline, that is, the slices, and finally combine them into mpt. Sometimes there are blurring or missing places in mpt because there are problems with the slices, especially the pyramids made from arcgis. Need to use the redo pyramid or use tb to rebuild the pyramid, see the pyramid analysis of generating mpt, of course, use tb to make a pyramid, and then do mpt, it is equivalent to copying and reorganizing the slices, which is much faster.

Tb also makes the elevation data into slices of the map, and according to the request of the te client, the request is made in batches, and the speed is much faster.

Merge a large number of slices into a mpt file to facilitate the copy of the data, of course, the data format can be encrypted, not open source format, except that he can not parse.

The above is all the contents of the article "sample Analysis of mpt in the second Development of TE". Thank you for reading!
