Multigrids Image Analysis
Multigrids menu options on Image analysis
Menu. You must have loaded the satellite image into memory before this
will work.
- Change display band
- Basic statistic: max, min, mean, std dev
- Scattergram of two bands
- Filter image
- Supervised classification
- Unsupervised classification
- Variance-covariance/Principal components
- Average reflectance in region
- Reinterpolate all to same resolution
- Will use the resolution of the grid with the smallest data
spacing
- Will use bilinear interpolation
- Will place files in a new subdirectory named "resolution_NN"
- Be judicious and select only those bands you want to use; with
Sentinel-2, this will increase the
storage required by 3 times.
- Create Max DN grid:
- Create Average DN grid: create and open a grid with the average DN in all bands.
- Create Min DN grid
- Locate values; create a database with all points within a given
range. This will have the LAT/LONG, BAND, and DN. This database
can become very large if you do not pick values judiciously. It can be
useful to find extreme values.
- Tail percentiles: create a database with key information on each band
- Normalize
