Buffer

 
   
Create a buffer around a GML geometry. Accepts a GML geometry and provides a GML geometry output for the buffered feature.

Intersection

 
    Intersection of 2 GML datasets.

PointInPolygonJoin

 
   
Join of GML data containing points with GML data containing polygons based on the spatial predicate "contains". All attributes of the points are kept (including the geometry) and the user can choose which attributes of the polygons shall be kept. Furthermore, the user can choose between four different join types: NATURAL, LEFT, RIGHT, FULL. The missing attribute values in cases of left, right or full join are filled with null.

PointInPolygonJoinAggregation

 
   
Join of GML data containing points with GML data containing polygons based on the spatial predicate "contains" followed by the aggregation of attribute values of the points. Available aggregate functions: count, sum, max and min. It is possible to keep attributes of the polygon data. All polygons (including the geometry) are added to the result data, independent from containing points or not.

PolygonIntersectsPolygonJoinAggregation

 
   
Join of 2 GML datasets containing polygons based on the spatial predicate "intersects" followed by the aggregation of attribute values of the first polygon dataset. Available aggregate functions: count, sum, max and min. In case of the aggregate function "sum" this value is calculated on a pro-rata basis. This means the ratio of the original polygon area and the intersection polygon area is calculated and the value to sum is multiplied by this ratio. It is possible to keep attributes of the second polygon dataset. All polygons of the second dataset (including the geometry) are added to the result data, independent from intersecting polygons of the first dataset or not.

Distance

 
   
Finds the closest points on two GML geometries and returns them as well as the euclidean distance between them. In case of two points the distance of the points is calculated. In case of higher dimensional input geometries the distance of the closest points (not necessarily vertices) is calculated. If one geometry contains the other, the distance is 0. If one or both of the input geometries are feature collections, thus contain multiple features, only the two closest features are considered.

GeometryMetrics

 
   
Calculates basic metrics of Features depending on the FeatureType. If the Input Geometry contains LineStrings, the length of the lines is calculated. If it contains Polygons, the area and perimeter is calculated.
