I am first and foremost an ecologist working to promote the integrity, stability and beauty of the biotic community.

Specialties: Remote sensing, GIS, spatial statistics, big data, wildlife conservation, and landscape ecology. My work focuses mainly on multispectral and Lidar remote sensing for assessing vegetation structure and composition.

I enjoy finding solutions to problems on this site that I otherwise would not have exposure to in my day-to-day work.

comment Why does ASTER created -0 to 0 instead of -1 to 1?
PROBERT, I wish that I could provide more details, however, I am unsure what you are trying to do. Generally, you do not want want to change the ASTER pixel values to integer prior to calculating NDVI. I would simply keep both in double or float format. You can calculate an index resembling NDVI without atmospheric correction, although you cannot assume NDVI values are consistent from ASTER tile to tile without the atmospheric correction.

You will have to track down the source of the data and look at the metadata--specifically the processing level.

comment NoData specification via IEEE NaN in GeoTIFF for ArcGIS
How does ArcGIS display your NoData value when you query the image using the identify tool? Also, have you tried right-clicking the raster layer in the table of contents > Properties... > Symbology > Display Background Value <your value> as <No Color>?
