<p style="margin-bottom:0in">GSOC Week 2 Check in</p><p style="margin-bottom:0in">An Implementation of Horizon based
Stratigraphy for GRASS7</p>
<p style="margin-bottom:0in"><br></p><p style="margin-bottom:0in">Hello everyone,</p><p style="margin-bottom:0in">This week I am checking in a bit early
because I am heading to the California Forest Soils Council meeting
in a matter of hours.
</p>
<p style="margin-bottom:0in">This week I developed a workspace based
on prior wetland mapping of a tidally influenced salt marsh in the
Northeast corner of Humboldt Bay, in Northwest California. I went
through each of the r3 modules to examine the current capabilities. In addition I have been
continuing to develop workspaces, focused on subsurface geologic
structures in Simi Valley, and Mountain View California.
</p><p style="margin-bottom:0in">One of the issues that is emerging are
the irregularities in how the borehole logs were recorded. I spent a
significant amount of time tracking down published research covering
the conversations on the Grass Dev listserve about
</p><p style="margin-bottom:0in">I looked into ordinal logistic
regression, as well as Tprogs for handling attribute data. Several
of the published Ore body assays, quantified z anisotropy compared to
xy. In addition I have continued to work on a generalized solution
for subsurface structures from p wave first arrivals on seismic
surveys.
</p><p style="margin-bottom:0in">Next week my primary task is going to
be to settle and code on the voxel assignment operator.
</p><p style="margin-bottom:0in">Finally I have come up with a bit of
branding. Since r.horizon is already being used by a viewshed module
I propose that my module to be named r3.strata. Kind of nice ring to
it. <br></p><p style="margin-bottom:0in"><br></p><p style="margin-bottom:0in">Tim Bailey</p>
