Hi Alice,

The original scale factor for that GHRSST product is 0.001, that is each
integer corresponds to 0.001 degrees. However I do not recommend using that
scale factor for the Cayula-Cornillon tool. The data are not accurate to that
precision, and using that scale factor will likely produce integers that
exceed the size of integers supported by the tool. I would recommend 0.01 or
even 0.05 instead. For the Map Algebra Expression, try:

int(inputRaster / 0.01)

Or:

int(inputRaster / 0.05)

Let me know how that goes.

Best,
Jason

Subject: [mget-help] Map algebra expression needed to use "Cayula-Cornillon
Front" detection tool

Hello MGET users,

I'm trying to use the "Cayula-Cornillon Fronts in ArcGIS Raster" tool, but
I'm unsure how to convert my floating-point raster into an integer raster
using the map algebra equation. My input raster is of averaged SST, derived
from
MUR-JPL-L4-GLOB-v4.1 rasters
(https://urldefense.proofpoint.com/v2/url?u=http-3A__podaac.jpl.nasa.gov_dataset_MUR-2DJPL-2DL4-2DGLOB-2Dv4.1&d=DwICAg&c=imBPVzF25OnBgGmVOlcsiEgHoG1i6YHLR0Sj_gZ4adc&r=cJfJ4ejc1xbg_qb47Pg1OoRq1GfFGvWbDD2PT7-fBKk&m=ZtCWXpdSuAO0Amh6v-DOJJzaQL3dPb6ZvlWrBOMm8r4&s=qliAsYc3mOxvN3RxDOc98ydhl2MYFTjswk4E3dpd3nA&e=
), which I downloaded using the MGET tool. Can anyone point me in the right
direction? Where do I find the equation for this data set?

Thanks very much, Alice
