EXAMINE THE IMAGE
Ensure the image is stored in a format
that is supported by FME Readers

CHECK PARAMETERS
Set all the necessary parameters.
SET THE OUTPUT
Ensure your output datasets are in the
right formats

INPUT DATA
Feed you model with data (vector AOI,
Point Clouds and Raster imagery)

CHECK OUTPUT
Examine the quality of the output
REDO(ALTER PARAMETERS
AND COMPARE OUTPUT)
Reset your parameters and rerun the
model
MAKE USE OF IT!
Share the model

Should a single process take more than the time it takes you to consume a cup of tea or coffee, don’t hesitate, kill
the process and revisit your parameters
