I've calculated NDVI using Sentinel data. Below is the part of my code. This code exporting TIFF file into my google drive, however, when I load this image into ArcMap and trying to convert this raster into shapefile its not happening. This image is opening into ArcMap, but its "Open attribute table" is not enable. I want to share this NDVI layer with other colleagues, so that, they able to calculate area of my NDVI layer. How can I resolve my problem? I'm new to Google Earth Engine

//setting range of my NDVI
var ndviRange1 = 0.344;

// Calculating NDVI

var ndvi1 = img.normalizedDifference(['B8A','B4']).rename('NDVI');
var ndviMask1 = ndvi1.gte(ndviRange1); //geater than

// Updating Mask
var NdviData=ndvi1.updateMask(ndviMask1);

//Exporting this mask
Export.image.toDrive({
      image: NdviData,
      description: 'DGKhanDivCo',
      folder:'DGKhanDivCo',
      scale: 05,
      region: roi,
      fileFormat: 'GeoTIFF',
      maxPixels: 1e12,
    });

I have find the following way to solve this problem in GEE (1) First Export your GEE NDVI Layer as Raster Tiff in your Google Drive using this code below:

 Export.image.toDrive({
      image: NdviData,
      description: 'DGKhanDivCo',
      folder:'DGKhanDivCo',
      scale: 05,
      region: roi,
      fileFormat: 'GeoTIFF', 
      maxPixels: 1e12, 
    });

(2) Download this Geotiff file from your Google Drive and make a Mosaic (If necessary) in Arc Map. Then Reclassify this raster according to your Bins.

(3) Convert this reclassify raster to polygon in Arcmap and then merge the polygons and calculate Area

In this way you can share Google Earth Engine calculated NDVI as Shapefile layer with your Colleagues. Any shortcut Idea will be appreciable
