Content transformations are those that operate on the geometry or attribute content of a dataset.
Geometric Transformation
Geometric Transformation is the act of restructuring the spatial component of an FME feature.In other words,the physical geometry of the feature undergoes some form of change to produce a different output.
Some examples of geometric transformation are…
- Generalization – a cartographic process that restructures data to be more easily visualized at a given map scale.
- Warping – adjustment of the size and shape of a set of features to more closely match a set of reference data.
- Topology Computation – conversion of a set of linear features into a node/line structure
Attribute Transformation
Attribute Transformation is the act of restructuring the non-spatial component of an FME feature.In other words,the attributes relating to the physical geometry undergo some form of change to produce a different output.
Some examples of attribute transformation are:
- Concatenation – joining together of two or more attributes.
- Measurement – measuring a feature's length or area to create a new attribute
- ID Creation – creation of a unique ID number for a particular feature
| Address1 Suite 2017 Address2 7445-132nd Street City Surrey Province British Columbia PostCode V3W 1J8 Concatenate Address1+","Address2+","City+","Province+","PostCode Output Suite 2017,7445-132nd Street,Surrey,British Columbia,V3W 1J8 |
Above: Example of attribute concatenation.Each line of the address is concatenated,along with some constants to get spaces and commas,to return a single line address.
