&lt;p&gt;&lt;strong&gt;&lt;span style="font-size:150%;"&gt;&lt;span style="text-decoration:underline;"&gt;Question:&lt;/span&gt;&lt;/span&gt;&lt;/strong&gt;&lt;/p&gt;
&lt;p style="margin:0in 0in 0.0001pt;background:white none repeat scroll 0% 0%;" class="rvps5"&gt;How do you create a control point?&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;&lt;span style="text-decoration:underline;"&gt;&lt;span style="font-size:150%;"&gt;Answer:&lt;/span&gt;&lt;/span&gt;&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;To create a control point:&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;Set the spatial reference system in the combo-box. &amp;#39;Cartesian&amp;#39; system can be used to enter non-georeferenced control points for instance in a local spatial reference system. For georeferenced control points, choose the desired spatial reference system before entering coordinates in the table.&lt;br /&gt;&lt;br /&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-02-18/clip1.png"&gt;&lt;img src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-02-18/clip1.png" alt=" " /&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;/li&gt;
&lt;li&gt;Click on&amp;nbsp;&lt;strong&gt;Add point&lt;/strong&gt;&amp;nbsp;to create a new control point in the selected spatial reference system.&lt;br /&gt;&lt;br /&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-02-18/clip2.png"&gt;&lt;img src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-02-18/clip2.png" alt=" " /&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;/li&gt;
&lt;li&gt;Set the control point properties.&lt;br /&gt;&lt;br /&gt;&lt;a href="/cfs-file/__key/communityserver-wikis-components-files/00-00-00-02-18/clip3.png"&gt;&lt;img src="/resized-image/__size/940x0/__key/communityserver-wikis-components-files/00-00-00-02-18/clip3.png" alt=" " /&gt;&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;&lt;ol&gt;
&lt;li&gt;Name - control point alias&lt;/li&gt;
&lt;li&gt;Category&lt;ol&gt;
&lt;li&gt;Full: XYZ coordinates will be used (default).&lt;/li&gt;
&lt;li&gt;Horizontal: only X and Y coordinates will be used.&lt;/li&gt;
&lt;li&gt;Vertical: only Z coordinates will be used.&lt;/li&gt;
&lt;/ol&gt;&lt;/li&gt;
&lt;li&gt;Check point - Enable this option if you want to use the control point for checking only. In such case the control point will not be considered for the aerotriangulation.&lt;/li&gt;
&lt;li&gt;Given 3D position - Edit the control point given 3D position in the corresponding columns. Coordinate units depend on the chosen spatial reference system.&lt;ol&gt;
&lt;li&gt;Cartesian: arbitrary unit, same unit for X, Y and Z (for georeferenced control points, Cartesian means&amp;nbsp;ECEF).&lt;/li&gt;
&lt;li&gt;WGS 84: latitude and longitude in degrees, ellipsoidal height in meters.&lt;/li&gt;
&lt;li&gt;Other: X, Y and height in meters.&lt;/li&gt;
&lt;/ol&gt;&lt;/li&gt;
&lt;li&gt;Horizontal accuracy - Enter the given accuracy for the X and Y coordinates of the control point. Control points with a higher accuracy will have more weight in the aerotriangulation.&lt;/li&gt;
&lt;li&gt;Vertical accuracy - Enter the given accuracy for the Z coordinates of the control point. Control points with a higher accuracy will have more weight in the aerotriangulation.&lt;br /&gt;&lt;br /&gt;&lt;br /&gt;&lt;/li&gt;
&lt;/ol&gt;&lt;/li&gt;
&lt;li&gt;Add image measurements - Select the photo on which you want to add a measurement, find the control point position in the photo, and use&amp;nbsp;Shift+Click&amp;nbsp;to set the image measurement position.&lt;/li&gt;
&lt;/ol&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
