When storing spatiotemporal data, there is a need to store dates or time data. I know raster files can store numeric data (integer or float), but what about storing of dates data?
I'm currently looking at the following options:
- Raster — Data are numeric values of the passed seconds from the Unix Epoch,
1970-01-01 00:00:00being the zeroth second
- ENVI .hdr labelled raster — Labels are in
- Raster + CSV file — CSV file contains
YYYY-MM-DDdate format along with numerical value lookup for the raster
- Raster — Data are numeric day-of-the-year, negative values and values larger than 365 are offsets and will be treated a different year
Is there a raster data format that can store dates instead of numeric values or utilizing labels and/or adding extra files?
If there aren't, at least, is there a de facto convention of how to store them on a raster file?
