GLCM Texture Features as Input of LandTrendr #8

Closed alejandro-fonseca closed 3 years ago

alejandro-fonseca commented 3 years ago

Thank you for this very useful algorithm!!. I have been using the Time Series Plotter to create time series with different vegetation index. However, I want to explore spatial associations in the land cover and I'm planning to use some texture features from GLCM. Once the annual medoid composition is created, I calculated the texture: Homogeneity for the band 1 of Landsat7 for every annual composition. Nevertheless, every time I try to run the algorithm using this new set the images (homogeneity) I get this error:

"Magnitude: Tile error: Image '0' does not have a 'system:time_start' property"

I share my code for further explanation: https://code.earthengine.google.com/?scriptPath=users%2Falefoncol%2FScripts%3ALandTrendr%2FLandTrendr-Thesis
