Dear all, I'm new in this forum and I like the professional discussions in this forum. I've a question regarding Spot S10 NDVI. I dowloaded the images from Spot Vgt website and the come as HDF are  unprojected. The images are in geographical coordinates (WGS 84) as per the header information and an attached  ASCII text. However, they are not georegistered and hence the fields for northings and eastings are missing values. I want to convert the images in geographical coordinates and then project them in order to stack them.   Any body with some ideas or suggestions?   Thanks in advances,   GeoTony
