How is a changedetector used in a FME?
Merges the attributes and/or geometry of one set of features onto anot… Detects features that are matches of each other. Features are declared… Filters features by test conditions to one or more output ports.
How is vector data digitised in GIS application?
Vector data (red lines) that was digitised from a small scale (1:1000 000) map. Vector data (green lines) that was digitised from a large scale (1:50 000) map. When you add vector layers to the map view in a GIS application, they will be drawn with random colours and basic symbols.
How does QGIS allow you to reproject data on the fly?
QGIS allows you to reproject data “on the fly”. What this means is that even if the data itself is in another CRS, QGIS can project it as if it were in a CRS of your choice. To enable “on the fly” projection, click on the CRS Status button in the Status Bar along the bottom of the QGIS window:
How are vector features group into layers in GIS?
Most GIS applications group vector features into layers. Features in a layer have the the same geometry type (e.g. they will all be points) and the same kinds of attributes (e.g. information about what species a tree is for a trees layer).
How to compare two files with FME information?
There’s nothing more to it. You can check that the geometry is the same, or just check attributes. See the description from FME help: ChangeDetector Detects changes between two sets of input features. This transformer is often used with multiple readers, to identify changed features in the two files.
Which is the best FME transformer for text search?
You can then try if a StringReplacer can replace the characters. If again a the german characters are not replaced correctly you could analyse the ASCII code with the CharacterCodeExtractor and replace it with CharacterCodeReplacer . See doc of CharacterCodeExtractor:
How does the FME tester evaluate a feature?
The Tester accepts any feature. It evaluates each feature against one or more user-defined tests, and outputs the feature via the Passedport if it meets the defined conditions, or via the Failedport if it fails the defined conditions.
