Dear list,
I am working with spatstat and am trying to define my owin: spatial region
(observation window). I have a set of marked planar point patterns generated
from random samplings in different strata. Unfortunately I don't have any
GIS file with all the information for each of my strata. I
Marcelino,
My dataset is coming from annual bottom-trawl surveys in waters off
Newfoundland and Labrador Region, Canada. I am looking at habitat selection
(relationship to depth temperature), geographic distribution, and
abundance of skate species in the region in 2009.
The survey use a
Thank you Agus, I'll look at qgis.

Hummm...
Thank you Marcelino, I agree with you, this dataset isn't a clear stochastic
point process per se, however I'm wondering if I can still treat it as such,
acknowledging the limitations. Would love hearing people comments.
I will look at the dismo package.
On a slightly different note,
Awesome! Thank you very much MArcelino!

My mistake, I avoided using the word 'bycatch' to not get into the
definition, but I am actually looking at bycatch events, in other words,
where the presence or absence of nontarget species i.e., shark/skate in the
catch is recorded as a single point for a specific fishing location.
Following
Thank you very much for this quick reply Dr. Bivand.
I am taking good notes of your suggestions.
I'm a little concern about your comments that my data are not a marked point
process and would like to verify with you a few points. You are correct that
my points - the catch positions are
Dear all,
I am new to spatial and point process analysis (as well as R), however most
of my Ph.D. will rely heavily on these tools *sighs :) I am starting a new
chapter where I intend to model elasmobranch i.e., shark and skate catch in
the Northwest Atlantic Canadian waters using point process
