Hi @JodiNorris and @agataelia @JodiNorris As for the change mapper screenshot... I think what you are seeing are artifacts that are the result of the combination of bicubic resampling we...

One thing that would help in these cases with removing artifacts I believe is to not use bicubic resampling. I'll look at updating the code so that it does not...

Hi @agataelia I recommend breaking up the export. In projects where my lab group ran LT on CONUS as exports, we had I think 15 zones. This was helpful for...

Note on allowing person to choose resampling method (don't resample on change mapping app): `buildSRcollection` has optional parameter which is a dictionary. Could add a key for resample method. In...

@Mcflyuu's code from email thread ``` var roi = table.geometry() // ImageCollection parameters definition var startYear = 1984; var endYear = 2020; var startDay = '06-01'; var endDay = '09-30';...

Can reproduce: https://code.earthengine.google.com/7c7396190dc4b3fa4f8aa0af6e62650a - WAI for pixels with greater than 1 segment that include both 'loss' and 'gain' segments - Bug for pixels with 1 segment, the single segment appears...

I suspect the problem is that the array returned from [`getSegmentData`](https://github.com/eMapR/LT-GEE/blob/de1f5f4c3bcf4c90872bafda584318e98f34ee75/LandTrendr.js#L1114) have no masked values, they are filled with value -9999, so will appear to have a segment when the...

@Mcflyuu I wonder if you would help test a fix? In my test, the count seems to be correct now: https://code.earthengine.google.com/bcc79285efd8230e7b1133c3d2a71772 If you replace: ```js var ltgee = require('users/emaprlab/public:Modules/LandTrendr.js'); ```...

The date for the annual medoid composites is hard coded. See line https://github.com/eMapR/LT-GEE/blob/8e38e0f5bb8813b42521fd9f8633eba5514b5674/LandTrendr.js#L217 The comment says August first, but the month parameters for the `Date` function is 0-based month index,...

Hi Alec, thanks for bringing this up! I've been updating some other scripts and wanted to share a nice function for scaling and masking L8 SR C2. It would have...
