Which algorithm I should use in ENVI 5.2 to open the MODIS product (MOD13Q1 or MODIS/Terra Vegetation Indices 16-Day L3 Global 250m Grid SIN V006), given as HDF file to ArcGIS 10.5 as correctly georeferenced raster showing the value of NDVI index?
The product is described here:
https://lpdaac.usgs.gov/dataset_discovery/modis/modis_products_table/mod13q1_v006
I tried to do it by ENVI 5.2. I opened it there (Open as – EO-1 – HDF4), but when I exported it directly by operation “Send to ArcMap”, it was opened in ArcMap with incorrect projection. The same things happened when I imported this hdf file to ASCII and after that in ArcMap used the “ArcCII to Raster” Tool. The resulting raster has incorrect projection.
In the description of this product (by link above) says that it has Sinusoidal Coordinate system. So I suppose I should change it in the properties of file. However, I can’t change this coordinate system in the files, which I created by ENVI.
So, I need to know – which algorithm I should use in ENVI 5.2?

After MODIS Conversion Toolkit installation you could use
Georeference MODIStool located in/Geometric Correction/Georeference by Sensor/which works well withMOD02QKMproduct (but not sure aboutMOD13Q1). After georeferencing - save output raster layer as tiff file and launch it with ArcGIS.
