Custom Transformers to be created

List of custom transformers that we can create

1. Flowpath creator: This transformer given a watermain shapefile, flow directions and a DEM, will trace a path from breakpoints (10m apart) for each watermain in the shapefile.
2. ML transformer: This transformer uses Machine Learning to output the LOF for a watermain
3. Flow Direction Calculator: Given a raster DEM as an input, the transformer will create a flow direction tiff file and allow the user to store it in a working directory.
4. Catchment Area Calculator: Given a pour point and a flow direction file, for each pour point arcpy will be used to calculate the catchment area.
5. Risk Score Calculator: Given watermain shapefile with (optional additional attributes included in the mains.csv), the transformer assigns a risk value (analysis value) to the watermain
6. Slope Analysis: Ties to Module 1
7. Building Analysis: Ties to Module 2, 3, 4
8. Creek Analysis: Ties to Module 5, 6, 7

Proposed Thought

1. Each Module could become a custom transformer
