Data is being wrongly displayed on some rasters visualizations (The scale int the raster zoom) #115

Describe the bug To optimize the image display GEE's algorithm to merge a certain number of pixels into one, but on doing that it merges pixels with different values into a new one. E.g, if we merge two pixels of 2 and 0 value, GEE turns it into a one pixel with value 1, which displays different colors in the final image. We must find a work around for that.

To Reproduce Steps to reproduce the behavior:

  1. Access https://oca.lsd.ufcg.edu.br/map?name=veg&year=2000 and see that it has a lot of pink dot areas
  2. Zoom in on any pink dot and you'll find out that it actually doesn't exists

Expected behavior We want a way of merging these pixels and still optimize the loading time but without creating distinct new value. A good algorithm may be to transform these pixels into a new one that's equal to the more frequently one.

solved (apparently). just waiting further orientations.
