<h2>Regionalization<a class="headerlink" href="#regionalization" title="Permalink to this heading"></a></h2>
<p>By regionalization, amplitudes and magnitudes can be computed depending on the
region of the source or source-receiver pairs.
Regions are defined by polygons in BNA or GeoJSON files which must be known to
<cite>SeisComP</cite>.</p>
<section id="amplitudes">

<p>Measuring amplitudes only for sources or pairs of sources and stations in
specific regions is possible by regionalization. The region polygons are defined
by <a class="reference internal" href="#tutorials-magnitude-region"><span class="std std-ref">magnitude regionalization</span></a>. In
order to use the feature, regionalized amplitudes and magnitudes must have the
same type (name) and regionalization must be activated per amplitude type in
amplitude-type profiles of global bindings.</p>

<span id="tutorials-magnitude-region"></span><h3>Magnitudes<a class="headerlink" href="#magnitudes" title="Permalink to this heading"></a></h3>
<p>With regionalization magnitudes can be computed with region-dependent parameters.
If magnitude regionalization is configured but a source or source-station pairs
are not considered, no magnitude of the corresponding type is computed.</p>
<section id="setup">
<h4>Setup<a class="headerlink" href="#setup" title="Permalink to this heading"></a></h4>
<p>The procedure to set up magnitude regionalization is:</p>
<ol class="arabic">
<li><p>Create one file which contains the polygons surrounding the regions within
which magnitude parameters shall apply. The polygon files are provided in
<a class="reference internal" href="../../apps/global_gui.html#sec-gui-layers-vector-format-bna"><span class="std std-ref">BNA</span></a> or
<a class="reference internal" href="../../apps/global_gui.html#sec-gui-layers-vector-format-geojson"><span class="std std-ref">GeoJSON format</span></a> and located as
set out in the <a class="reference internal" href="../../apps/global_gui.html#sec-gui-layers"><span class="std std-ref">documentation of map layers</span></a>. The file
can be created from any <cite>SeisComP</cite> GUI application providing maps, e.g.,
<a class="reference internal" href="../../apps/scmv.html#scmv"><span class="std std-ref">scmv</span></a>.</p></li>
<li><p>For the desired magnitude type create a magnitude-type profile in global
module configuration. The name of the profile matches the name of the
magnitude, e.g., <em>MLc</em> for the <a class="reference internal" href="../../apps/global_mlc.html#global-mlc"><span class="std std-ref">MLc magnitude</span></a>.</p></li>
<li><p>Configure the <code class="xref std std-confval docutils literal notranslate"><span class="pre">magnitudes.MLc.regionFile</span></code> parameter with the full
path and name of the polygon file created above.</p></li>
<li><p>Within the magnitude-type profile create one or more magnitude-region
profile(s) for defining the regionalized parameters applied to the region(s).
The name of a profile corresponds to the name of the polygon contained in the
polygon file to which the parameters shall apply. Use <em>world</em> for all regions
not covered by any polygon.</p></li>
<li><p>Configure the regionalized magnitude parameters of the magnitude-region
profile. Activate the <em>enable</em> parameter if you wish to apply this profile.</p></li>
<li><p>Restart the data processing:</p>
<div class="highlight-sh notranslate"><div class="highlight"><pre><span></span>seiscomp<span class="w"> </span>restart
</pre></div>
</div>
<p>or execute a GUI module.</p>
</li>
</ol>
<div class="admonition important">
<p class="admonition-title">Important</p>
<ul class="simple">
<li><p>Parameters which can be configured along with regionalization assume
defaults from global binding parameters but override global bindings
parameters when configured.</p></li>
<li><p>Once regionalization is active, magnitudes for events outside the
defined region(s) will not be computed. For considering such events add
another magnitude-region profile with the name “<em>world</em>”.
Magnitudes for events outside any other magnitude-region profile will then
be computed according to this profile.</p></li>

<p>Configuration of bindings profiles has the advantage that the parameters are
available on any client connected to the messaging including external
SeisComP systems. Writing to global module configuration may be more simple
than maintaining multiple bindings profiles but the configuration is not

<p>When initially configuring amplitude and magnitude aliases, <a class="reference internal" href="../../apps/scconfig.html#scconfig"><span class="std std-ref">scconfig</span></a>
does not know which original amplitude and magnitude types are considered and

original types:</p>

<li><p>Copy or rename the name of the referenced amplitude or magnitude in the

<li><p><strong>Write bindings parameters to global module configuration:</strong> Manually
adjust the module configuration file, e.g., <code class="file docutils literal notranslate"><span class="pre">global.cfg</span></code>. The
operation is not supported by <a class="reference internal" href="../../apps/scconfig.html#scconfig"><span class="std std-ref">scconfig</span></a>.</p>
<ol class="arabic">
<li><p>Read the relevant parameter names of the original magnitude from global
binding, e.g., in <a class="reference internal" href="../../apps/scconfig.html#scconfig"><span class="std std-ref">scconfig</span></a>. The names must include the full
hierarchy including all sections. Example:</p>
<div class="highlight-properties notranslate"><div class="highlight"><pre><span></span><span class="na">magnitudes.MLc01.parametric.c1</span>
</pre></div>

</li>
<li><p>Open the module configuration file, e.g.,
<code class="file docutils literal notranslate"><span class="pre">seiscomp/etc/global.cfg</span></code> in a text editor.</p></li>
<li><p>Prepend <em>module.trunk.global.</em> to the parameter name and add it along with
its value to the configuration file for all networks and stations.
Example:</p>
<div class="highlight-properties notranslate"><div class="highlight"><pre><span></span><span class="na">module.trunk.global.magnitudes.MLc01.parametric.c1</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="s">0.7</span>
</pre></div>

<p>For a given network or network and station replace <em>global</em> by the
<em>network</em> or the <em>network</em> and the <em>station</em> code. Example for network
CX and station PB01:</p>

<p>The configuration procedure is:</p>
<ol class="arabic">
<li><p>Set up a magnitude-type profile for the original magnitude type in global
module configuration. Use <a class="reference internal" href="../../apps/scconfig.html#scconfig"><span class="std std-ref">scconfig</span></a> for creating the profile.</p></li>
<li><p>Configure the parameter <em>MwMapping</em>, which will become available along with
the new profile, e.g., <code class="xref std std-confval docutils literal notranslate"><span class="pre">magnitudes.MLc.MwMapping</span></code>. Alternatively,
add the parameter to <code class="file docutils literal notranslate"><span class="pre">seiscomp/etc/global.cfg</span></code>. The parameter is
configured as a list of sample points of a piecewise linear function mapping
from the original magnitude, Mx, to Mw(Mx).
Example for Mw(MLc) based on MLc:</p>
<div class="highlight-properties notranslate"><div class="highlight"><pre><span></span><span class="na">magnitudes.MLc.MwMapping</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="s">MLc_0:Mw(MLc)_0,MLc_1:Mw(MLc)_1,...,MLc_N:Mw(MLc)_N</span>
</pre></div>
</div>
<p>Any magnitude value outside the configured range is ignored.</p>
</li>
</ol>
<p>The new moment magnitudes will be available along with the original magnitudes
and can be viewed in <a class="reference internal" href="../../apps/scolv.html#scolv"><span class="std std-ref">scolv</span></a> or <a class="reference internal" href="../../apps/scesv.html#scesv"><span class="std std-ref">scesv</span></a> and considered by <a class="reference internal" href="../../apps/scmag.html#scmag"><span class="std std-ref">scmag</span></a>
or <a class="reference internal" href="../../apps/scevent.html#scevent"><span class="std std-ref">scevent</span></a>.</p>
<p>In order to avoid that <a class="reference internal" href="../concepts/magnitudes.html#concepts-magnitudes-summary"><span class="std std-ref">summary magnitudes</span></a>

the original magnitudes can be blocklisted in <a class="reference internal" href="../../apps/scmag.html#scmag"><span class="std std-ref">scmag</span></a>
