| Subject: | [mget-help] Trouble with Predict GAM from Rasters tool |
| Date: | Wed, 21 Mar 2012 18:10:35 -0400 (EDT) |
Good Afternoon,
I am using the Marine Geospatial Ecology Tool to create a habitat suitability
model for the Galapagos Islands. I have been following the steps from the
Webinar given by Jason Roberts, however, I am having some difficulty with the
last step. I chose to run a Generalized Linear model for my data, which
consist
of a Bathymetry DEM for the Galapagos, satellite images for chlorophyll a, sea
surface temperature and current speed. Two of the layers (SST and Chla) were
interpolated using a Universal kringing to calculate some missing values which
were close to the coast. I ran the model and received a file which I used as
my
input model file for the Predict GAM from rasters tool. My problem comes in
here; I can not get the tool to work. I have gotten error messages stating
that
the Chla layer can not be projected even though I have checked and the Chla
and
the other layers are in the same projection. I have also tried making each
layer the same size. When I tried this approach, I received a new message
saying that all the predictor rasters must have the same number of rows and
columns. This would be impossible for me since all my layers were retrieved
from different satellites, each one having a different resolution.
I really need some advice on how to rectify this problem. This toolbox has
helped me immensely so far, I would like to see and finally finish my model.
Best regards
Roxanne Duncan
