Create Georeferencing information for Instrument Approach Procedures and Airport Diagrams
These instructions are based on using Ubuntu (or some other Debian variant)
How to get this utility up and running:
Enable the "universe" repository in "Software & Updates" section of System Settings and update
Install git
sudo apt-get install git
Download the repository
git clone https://github.com/jlmcgraw/GeoReferencePlates
Execute the setup.sh shell script
./setup.sh
Download some Instrument Approach Procedure plates and initialize the database
- Download these with the "load_dtpp_metadata.pl" file
This will also re-initialize the dtpp.db file, be careful
- A download of all plates will probably take several hours
Requires a database containing lat/lon info
(This is created by another of my projects at https://github.com/jlmcgraw/processFaaData)
Requires perl version > 5.010
How to use these utilities
To georeference instrument procedures:
./georeferencePlatesViaDb.pl <options> <directory_with_PDFs>
-v debug
-a<FAA airport ID> To specify an airport ID
-i<2 Letter state ID> To specify a specific state
-p Output a marked up version of PDF
-s Output statistics to dtpp.db about the PDF
-c Don't overwrite existing .vrt
-o Re-create outlines/mask files
-b Allow creation of vrt with suspected bad lon/lat ratio
-m Allow use of non-unique obstacles
To georeference airport diagrams:
Usage: ./georeferenceAirportDiagramsViaDb.pl <options> <directory_with_PDFs>
-v debug
-a<FAA airport ID> To specify an airport ID
-i<2 Letter state ID> To specify a specific state
-p Output a marked up version of PDF
-s Output statistics to dtpp.db about the PDF
-c Don't overwrite existing .vrt
-p will create two extra files:
marked-*.pdf
Shows how the ground control points were matched
A green circle indicates which were used
gcp-*.png
Uses lon/lat information from the database to draw the ground control points. If the red dots don't seem to match up with a feature (obstacle, fix, nav aid) the georeference probably wasn't accurate
The green dot is the airport lon/lat
The first time the utility is run for a particular PDF it will take longer as it is generating the corresponding PNG and mask files. These will not be created again if they exist
A first run for all plates may take a day or two, subsequent runs will be much shorter
Running Refresh the location info database https://github.com/jlmcgraw/processFaaData
Add in the cifp database for use with verifygeoreference.pl
https://github.com/jlmcgraw/parseCifp
Create empty ./dtpp folder
./load_dtpp_metadata.pl . 1409
Download DTPP XML catalog, create DTPP database and download procedures. Change cycle number as needed
./georeferencePlatesViaDb.pl -m -p -s ./dtpp/
./georeferenceAirportDiagramsViaDb.pl -p -s ./dtpp/
