How to convert raster to point in QGIS

If you want to export Pvalue raster image from GEE and present it as a points grids in the map. Like:

a–c, MODIS Terra (550 nm; a), MISR (558 nm; b) and CAM5 in offline mode (550 nm; c). The black dots represent significance at 95% confidence level.

If you’re using a version of QGIS that integrates SAGA algorithms, you can use the Grid values to points tool. You'll find it in the processing toolbox under SAGA (at least for QGIS 2.4.0).

AGA Raster values to points tool (QGIS Processing Toolbox | SAGA | Vector <-> raster). Choose [1] cells as Type option.

Of Course, you can directly export the converted points from the raster from GEE:

var vectorExport = PImageExport.sample({
// numPixels: 10000,
region: pvalueRegion,
geometries: true,
scale: 40000
});

Export.table.toDrive({
collection: vectorExport,
description: ‘global_flood_crr_rf_095_test’,
fileFormat: ‘SHP’
});
