This article mainly introduces what are the common problems in the secondary development of TE. What is introduced in this article is very detailed and has a certain reference value. Interested friends must read it!

In the process of te system development, we often encounter some problems, the following are listed.

1. Vector layer query in te, only vector layer objects loaded in te can be queried using api. If you want to query all the objects of the layer, you need to query the source data of the layer in other ways. In the vector layer published by geoserver and arcgis, there are related services for query, and various class libraries can be read in the shp file.

2. When the shp file is loaded into skyline te or sfs, it will produce a file with the same name as shp with the suffix .qix, which is a cache file. You have to delete this file when replacing shp, or the data may not be updated when the client refreshes.

3. Mpt is also a collection of slices, which contains the information of zooming the highest level. if you want to load a high-precision image or elevation data into the map, and the accuracy of mpt is not as accurate as the data to be loaded, then the loaded image or elevation can only be displayed to the highest level of mpt, so there will be the problem of blurred loaded data. In this case, you can add a high-precision image when making mpt. As long as there is a small piece

4. When the image is opened with arcmap, a pyramid file will be generated and loaded in tb, and the pyramid file will also be recognized. Sometimes the generated mpt will be blurred, so you need to set the image or the pyramid whose elevation is te in tb.

5, in the development of cs, according to the mode of bs to write the code to draw polygon, once there is polygon self-intersection, the program will throw an exception, but not in bs, so if you use ExteriorRing in cs, please refer to the "TE secondary development drawing polygon" of this official account.

6. Te connects to the data on the web server, or published data such as sfs. Some caches are stored in the ie browser cache. If the server updates the data and the client does not change, you need to clear the ie cache.
