    <subfield code="a">&lt;p&gt;&lt;strong&gt;Study area&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;The study area in Eigenbilzen is situated in the agricultural zone east of the locality of Eigenbilzen, in the province of Limburg, Flanders, Belgium. The flights picture a wheat field where damage by wild boar is apparent.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Data collection&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;Data were collected by the &lt;a href="https://www.inbo.be/en"&gt;Research Institute for Nature and Forest (INBO)&lt;/a&gt; with a fixed wing drone Gatewing X100 in 2015 (2 flights). RGB data were acquired using an off-the-shelf Ricoh GR Digital IV camera, with the following image bands: 1: red, 2: green, 3: blue, 4: alpha channel. CIR (color-infrared) data were acquired using a NIR-enabled Ricoh GR Digital IV camera, with the following info bands: 1: NIR, 2: red, 3: green, 4: alpha channel.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Data processing&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;The raw data were processed to Digital Surface Models and orthophotos by INBO in 2015 using Agisoft PhotoScan Pro 1.0.4, a structure-from-motion (SfM) based photogrammetry software program.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Coordinate reference system&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;All geospatial data have the coordinate reference system &lt;code&gt;EPSG:31370 - Belgian Lambert 72&lt;/code&gt;.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Files&lt;/strong&gt;&lt;/p&gt;

&lt;ul&gt;
	&lt;li&gt;&lt;strong&gt;Raw flight data&lt;/strong&gt;: images and logs collected by the drone during flight. These files are zipped per flight, with the date (&lt;code&gt;yyyymmdd&lt;/code&gt;) and flight number (&lt;code&gt;x&lt;/code&gt;) indicated in the file name (&lt;code&gt;flight_yyyymmdd_Bilzen_x.zip&lt;/code&gt;).&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Processed data&lt;/strong&gt;: Digital Surface Models (&lt;code&gt;filename_DSM.tif&lt;/code&gt;) and orthophotos (&lt;code&gt;filename_Ortho.tif&lt;/code&gt;) stitched together from the raw data. The included flight is indicated in the file name (e.g. &lt;code&gt;20150728_Bilzen_1_DSM.tif&lt;/code&gt;).&lt;/li&gt;
	&lt;li&gt;&lt;strong&gt;Ground control points&lt;/strong&gt;: not applicable for this dataset.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;&lt;strong&gt;Cloud Optimized GeoTIFF&lt;/strong&gt;&lt;/p&gt;

&lt;p&gt;The most efficient way to explore the processed data is by loading the &lt;a href="https://www.cogeo.org/"&gt;Cloud Optimized GeoTIFFs&lt;/a&gt; we created for each processed file. Copy one of the file URLs below and follow e.g. the &lt;a href="https://www.cogeo.org/qgis-tutorial.html"&gt;QGIS tutorial&lt;/a&gt; to load this type of file.&lt;/p&gt;
