sampleterrain's Issues

Get request error when running example command

Hi @jimmyangel,

When I was running the example command node sampleterrain.js -f ./sampledata/test1.json > sampled.json, I got the following error:

Sample terrain error RequestErrorEvent {
  statusCode: 401,
  response: IncomingMessage {
    _readableState: ReadableState {

      highWaterMark: 16384,

      length: 62,

      readingMore: true,
      decoder: null,
      encoding: null,

    },
......
}

How can I fix it? Thanks a lot

Upgrade to latest terrain service from Cesium Ion (Cesium.createWorldTerrain())

Height value is undefined

Hi @jimmyangel,

I got the following error:

node sampleterrain.js -f data.json -t 'my Cesium Ion token'  > sampled.json

This is because the some height values are undefined.

If I take a smaller data.json as input, the code can be executed successfully and smoothly. Hence, I guess this might be relative to my data size? Cesium.sampleTerrain can not process such an amount of data at the same time?

use of (sampleTerrainMostDetailed) insted of (sampleTerrain)

Hi there,
I've used this tool and it works great for me. However, in my clone I have replaced (sampleTerrain) with this new function sampleTerrainMostDetailed. It is better since sometimes the level (default 11) is not available/known for every area.
again, thanks for the nice tool :)
