2.2. I did not set a parent object, and the way to download it was the same for both times. I downloaded it several times, but the corners were still in the center.

3.My idea is that RWT can use the texture of Onlinemaps.

2. No idea. RWT always generates a container aligned to the same corner.
Most likely you manually created a parent for the terrain.
Fixing this is very easy:
- Create an empty GameObject child for terrain.
- Set its position to (0, 0, 0).
- Move this object to the root of the scene.
- Place the terrain inside this object.

3. Unfortunately, I don't understand the question.
If you mean to use Online Maps tiles to generate terrains using RWT, this is not possible.
If you mean to use a texture generated by RWT in Online Maps, then it is possible. If you need I can give you an example how to do this.

“RealWorldTerrainContainer.GetInstances()[0].GetWorldPosition(FlgtDataSet.Instance._dUAVLon, FlgtDataSet.Instance._dUAVLat, FlgtDataSet.Instance._fUAVAlt, out v3Temp);”

2. Questions about the anchor location of downloaded terrain.
I first downloaded a large range of terrain using RWT, and then downloaded a small high-precision terrain.
However, the anchor point of the former is in the lower left corner, but the latter is in the center.
This caused me some trouble with coordinate conversion.
How does this need to be set? Why is there such a difference between the two?
I didn't actually make any special settings. Generally speaking, where is the anchor point for the downloaded terrain? I have attached the anchor location images of the terrain I downloaded twice. Please check them.

3. Do you mean that the downloaded offline satellite images in onlinemaps cannot be used for the terrain downloaded by RWT? Must I use the satellite image texture automatically downloaded by RWT to attach to the elevation?

Thank you for your help. I feel like I'm not far from success.

Please tell me more about your problem with coordinate conversion.

No, RWT uses a publicly available conversion algorithm from Google.
See RealWorldTerrainUtils.LatLongToTile.

Please attach your generation settings and object coordinates, I will check it.

Maybe the problem is in your conversion method.
Try using RWT API (RealWorldTerrain.RealWorldTerrainMonoBase.GetWorldPosition) .

I have encountered another problem.
I first downloaded a large range of terrain using RWT, and then downloaded a small high-precision terrain.
However, the anchor point of the former is in the lower left corner, but the latter is in the center.
This caused me some trouble with coordinate conversion.
How does this need to be set? Why is there such a difference between the two?

In addition, does our plug-in have its own coordinate conversion method about conversion of unity coordinates and true longitude and latitude coordinates?
I added a target on onlineMaps, and then transferred the corresponding position of longitude and latitude in the three-dimensional terrain to generate the target. But I found a significant positional difference between the two. I use my own method to convert, and I feel there is a certain error. I downloaded Google's satellite maps, while I used Mapbox for RWT.
I don't know if my conversion method is not very accurate or if the two map sources are different.  Can I directly apply the downloaded offline satellite images from onlinemaps to the RWT Terrain? HAHA~ Can you give me some suggestions? Be deeply grateful!

By the way, these two plug-ins work well together. They help me a lot, you too.
