<h1>Ground Control Points<a class="headerlink" href="#ground-control-points" title="Permalink to this heading"></a></h1>
|
||
<p>Ground control points are useful for correcting distortions in the data and referencing the data to know coordinate systems.</p>
|
||
<p>A Ground Control Point (GCP) is a position measurement made on the ground, typically using a high precision GPS. (Toffanin 2019)</p>
|
||
<p>Ground control points can be set existing structures like pavement corners, lines on a parking lot or contrasting color floor tiles, otherwise can be set using targets placed on the ground.</p>
|
||
<p>Targets can be purchased or build with an ample variety of materials ranging from bucket lids to floor tiles.</p>

|

<h2>Recommended practices for GCP setting<a class="headerlink" href="#recommended-practices-for-gcp-setting" title="Permalink to this heading"></a></h2>
|
||
<p>Keep ground control points visible for all camera locations. Consider the expected ground sampling distance, illumination, vegetation, buildings and all the existing obstacles.</p>
|
||
<p>Procure an evenly horizontal distribution of the GCPs within the project, covering high and low elevations. A minimum of 5 GCP works for most of the jobs, and for larger projects 8 – 10 are sufficient. Locate some points near the corners and others in the center, considering that GCP spacing should be larger than the image footprint so that you can’t see more than one GCP in a single image.</p>
|
||
<p>In order to ensure each GCP are found in at least 5 images, separate the points 10 to 30 meters from the perimeter of the project. This distance is dependent of the overlapping, so increasing overlapping should reduce the required distance from the perimeter.</p>

<p>If you supply a GCP file called <code class="docutils literal notranslate"><span class="pre">gcp_list.txt</span></code> then ODM will automatically detect it. If it has another name you can specify using <code class="docutils literal notranslate"><span class="pre">--gcp</span> <span class="pre"><path></span></code>. If you have a gcp file and want to do georeferencing with exif instead, then you can specify <code class="docutils literal notranslate"><span class="pre">--use-exif</span></code>. If you have high precision GPS measurements in your images (RTK) and want to use that information along with a gcp file, you can specify <code class="docutils literal notranslate"><span class="pre">--force-gps</span></code>.</p>

<p><a class="reference external" href="http://diydrones.com/profiles/blogs/ground-control-points-gcps-for-aerial-photography">This post has some information about placing Ground Control Targets before a flight</a>, but if you already have images, you can find your own points in the images post facto. It’s important that you find high-contrast objects that are found in <strong>at least</strong> 3 photos, and that you find a minimum of 5 objects.</p>
|
||
<p>Sharp corners are good picks for GCPs. You should also place/find the GCPs evenly around your survey area.</p>
|
||
<p>The <code class="docutils literal notranslate"><span class="pre">gcp_list.txt</span></code> file must be created in the base of your project folder.</p>
|

<p>For good results your file should have a minimum of 15 lines after the header (5 points with 3 images to each point).</p>
