+Formatted String
+
+
+
+
Example mapping:
+
+ The formatted string function enables users to access attribute values and project variables to create concatenated string values. Enter text in the text field and double click
+ on any available attribute value displayed in the function dialog to add the value. Alternatively press Ctrl+Space to access available variables and project variables. The entered values are concatenated to create string values in the target attribute.
+
+ 
+
+ 
+
+
+
+
Example mapping:
+
+The aggregate function combines the input source features to create MultiLineString, MultiPoint or MultiPolygon features. The aggregate function performs a check to ensure that the input features have the same source CRS. In the cases of input multi geometries, a new multi geometry is created.
+When different input geometry types are aggregated, you will receive a warning in the transformation log but the function will combine the geometries in a generic GeometryCollection.
+In the case of lines the aggregate function tries to combine them to create a MultiLineString in which the individual lines are connected (i.e. end vertex of one line is the start vertex of the next one).
+If this is not possible there is no guaranteed order in the MultiLineString.
+
+The aggregate function is often used in combination with the type level merge function. This is necessary to combine the geometries to create multi features and avoid selecting just one geometry from the merged geometries.

The interior point algorithm computes sections along a horizontal scan line in the interior of the polygon. The final interior point is the midpoint of the widest computed section in the interior of the polygon.
For properties with multiple geometries, the Interior Point function selects the first geometry.

+Spatial Join
+
+
+
+
Example mapping:
+
+Spatial joins can join multiple datasets together based on the spatial relationship between geometries.
+Spatial joins support the relation types contains, covered by, covers, crosses, equals, intersects, overlaps, touches, and within.
+
+Spatial joins are implemented based on the DE-9IM model.
+
+CONTAINS: Every point of the other geometry is a point of this geometry, and the interiors of the two geometries have at least one point in common. Geometries do not contain their boundary.
+if a geometry A is a subset of the points in the boundary of a geometry B, B.contains(A) = false.
+CONTAINS is the converse of WITHIN.
+
+COVERED BY: Every point of this geometry is a point of the other geometry.
+This predicate is similar to WITHIN but is more inclusive (i.e. returns true for more cases).
+COVEREDBY is the converse of COVERS
+
+COVERS: Every point of the other geometry is a point of this geometry. This predicate is similar to CONTAINS but is more inclusive (i.e. returns true for more cases). Unlike CONTAINS it does not distinguish between points in the boundary and in the interior of geometries. For most situations, covers should be used in preference to contains.
+COVERS is the converse of COVEREDBY.
+
+CROSSES: The geometries have some but not all interior points in common.
+
+EQUALS: Tests whether this geometry is topologically equal to the argument geometry.
+
+INTERSECTS: The geometries have at least one point in common.
+
+OVERLAPS: The geometries have at least one point each not shared by the other (or equivalently neither covers the other), they have the same dimension, and the intersection of the interiors of the two geometries has the same dimension as the geometries themselves.
+
+TOUCHES: The geometries have at least one point in common, but their interiors do not intersect.
+
+WITHIN: Every point of this geometry is a point of the other geometry, and the interiors of the two geometries have at least one point in common. The boundary of the geometry is not within the geometry.
+If a geometry A is a subset of the points in the boundary of a geometry B, A.within(B) = false.
+WITHIN is converse of CONTAINS
