Errors on zoom-in, zoom out for elevations

Hi,

I have an Openlayers3 map display, i switch it from 2d to 3d using ol3cesium.

Then i am loading .terrain files for elevations.

I am getting below errors, when i am zooming-in on elevations in Cesium:

Cesium.js:430 An error occurred in “yg”: Failed to obtain image tile X: 723 Y: 412 Level: 10.

Cesium.js:430 An error occurred in “yg”: Failed to obtain image tile X: 722 Y: 411 Level: 10.

Cesium.js:430 An error occurred in “yg”: Failed to obtain image tile X: 722 Y: 412 Level: 10.

Cesium.js:430 An error occurred in “yg”: Failed to obtain image tile X: 722 Y: 410 Level: 10.

I dont want my application do these unwanted disk access. How can i fix this?

Hi there,

There are many reasons you could be getting imagery tile errors. If you only want to load tiles in a specific region, take a look at this thread: https://groups.google.com/forum/?hl=en#!searchin/cesium-dev/imagery$20mask|sort:date/cesium-dev/Ac35kzLLX-I/_hyPWm2ZBQAJ

Hi Rachel,
Actually i have analysed my code and i am getting these errors when I am switching from 2d (openlayers) mode to 3d (ol3cesium). I am loading local tiles(.pngs) of a particular area. But it seems it is trying to load unavailable tiles in the folder. I think the resolution could be that it should not load unwanted area tiles…
