Aim of the Presentation
Illustrate two “real” world example on how FME is being used at MCE:
Map Production Environment
Map Revision Cycle
A R&D Environment
Develop an automated means of manipulating and extracting large raster & vector datasets based on an area of interest to formats that can be used for the DND Maritime Helicopter Project (MHP).
Map Production Revision Cycle
Current Revision Cycle Workflow Aim is to update the Cartographic Databases with
only the features that have been revised in the Feature Extraction Database

Aim:
To develope an automated means of manipulating and extracting large raster & vector datasets based on an area of interest and export the data to formats that can be used for the DND Maritime Helicopter Project (MHP).
Conceptual Overview of Workflow
in a R&D Environment (Cont.)
Folders containing both
the AOIs and data to be
extracted.
Create and index file
of where the data is located.
Clip the different types of
data based on the AOIs.
Creating mosaic of
the results and exporting
to GeoTiffs, DEM, Shapes
Workbench Used to Create Index Shape FilesThe resulting index
contains the X and Y
coordinates of
each TPC charts, the
location of the source
folder („Path‟) and the
name assigned to each
individual chart. The
indexes are used to
automated the selection of
all TPCs intersecting
an AOI (red box in previous
slice) (TPC-Tactical Pilot Charts)
in a R&D Environment (Cont.)
QC of Elevation Data:A Workbench was
used to extract
Elevation data from
DVOF and compare it
with DTED.
In some cases, found
errors in the DVOF.
in a R&D Environment (Cont.)
Conclusion
FME is a very versatile and powerful tool.
From the two sample workflows, it is obvious that it‟s not only for data conversion.
If your current tool cannot do the job, look to FME for a solution…
Thank You!
