This article mainly introduces how to load vector layers in TE, which has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, let the editor take you to understand it.

In the vector layer loaded in TE, when the amount of data is too large, the speed of streaming data display will be relatively slow, using layer loading, the system resources account for more.

This paper introduces a loading method of vector layer, which converts vector layer into picture, of course, the data cannot be queried in this way, and the accuracy of data display is not as good as that of vector display directly. this way is fast display speed and low resource consumption.

The specific ways to deal with it are:

Convert the vector data into picture format through arcgis, or publish the data through server, request a picture according to the size, the background of the picture is required to be transparent, so that the displayed data does not have anything extra, and the aspect ratio of the picture also conforms to the four range coordinates of the vector layer.

According to the line layer in the following example, you can view the four directional coordinates of the layer in the properties of the layer.

After the picture is generated, create a polygon of four points on TE. The coordinates are spliced according to the coordinates of the four corners. Set the path of the picture in the Texture of polygon. Sometimes the direction of the picture added may be incorrect. You need to set parameters in Rotate to rotate the picture.

If the picture is not displayed clearly, you can increase the size of the generated picture.

Through the above way, a vector layer can be directly displayed with a polygon object, which is helpful to the use of resources and efficiency of the system.

Thank you for reading this article carefully. I hope the article "how to load Vector layers in TE" shared by the editor will be helpful to you. At the same time, I also hope you will support us and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
