Geotiffer is in early dev phase (pre-alpha at best)... use at your discretion.

Geotiffer is a geopdf to geotiff converter, built specifically to handle batch conversion. It is based on the topics covered in a USGS whitepaper titled "Converting US Topo GeoPDF® Layers to GeoTIFF"

In addition, support for GE Super Overlay output has been added (via gdal2tiles).

Currently, Geotiffer is being developed for use on Windows machines.

To use...

Note: Obtain geoPDFs from https://store.usgs.gov, make sure you download one of the latest editions.

1. You'll need these installed:

• Python 2.6 or 2.7 variants
• GDAL and Python bindings (the packages found here: http://www.gisinternals.com/query.html?content=filelist&file=release-1600-gdal-1-11-0-mapserver-6-4-1.zip

2. Run print_layers.py to confirm your map/maps have the layers you expect. Pass a file or a directory (if directory, all pdf files in the dir will be analyzed).

• python print_layers.py <file_or_directory>

3. Review config items in config file, geotiffer.cfg (or create your own config file). Most notable is a list of layers you want to include. See below for more on config items.
4. Run geotiffer.py on a file or directory (works like print_layers.py) to produce geotiffs.

• python geotiffer.py <file_or_directory> <config_file_path>

1. Run print_layers.exe to confirm your map/maps have the layers you expect. Pass a file or a directory (if directory, all pdf files in the dir will be analyzed).

• print_layers.exe <file_or_directory>

2. Review config items in config file, geotiffer.cfg (or create your own config file). Most notable is a list of layers you want to include. See below for more on config items.
3. Run geotiffer.exe on a file or directory (works like print_layers.py) to produce geotiffs.

• geotiffer.exe <file_or_directory> <config_file_path>

1. You'll need:

• py2exe

2. cd to geotiffer repo root directory
3. run the bundler (this must be run from the root directory of the repo - otherwise errors will occur)

• python .\bundle.py

1. unpack geotiffer.zip
2. use the exe files as needed (see above)
3. leave all dlls in the same directory as exe files
4. use on any windows computer (no install required)

layers = Map_Frame.Projection_and_Grids,Map_Collar,Map_Frame.Woodland,Images

• comma separated list of layers to include/exclude (based on value of 'layers_mode')

layers_mode = off

• on/off, the layers listed in 'layers' will either be 'on' or 'off' (included or excluded)
• if value is 'on', only the listed layers are included
• if value is 'off', all layers except the listed layers are included

append_filename = geotiff

• text to be appended to geotiff output files

dpi = 300

• dpi of output geofiff files
• this option impacts speed: start with a smaller dpi if you want to play around with other options before creating your final product

fix_no_data = off

• when on, this option will attempt to remove all white from behind the countour lines
• this feature is experimental... more dev is needed to refine it
• do not use this if including imagery layer (unexpected results)

x_trim_factor = 153

• amount to crop the x axis (left and right sides)
• use this to remove edge artifacts within the given map(s) (extra whitespace, etc)

y_trim_factor = 138

• amount to crop the y axis (top and bottom)
• use this to remove edge artifacts within the given map(s) (extra whitespace, etc)

threaded = True

• toggle threaded processing

threads = 8

• if threaded is on, define number of threads to use
• generally 2 threads per core is the max

edge_smoothing_factor = 10

• edge smoothing will attempt to correct for "rotated" topo maps
• use if gaps appear at borders between stitched maps
• set to 0 to turn off

produce_tiles = yes

• produce ge superoverlay
• turn off to save processing time

tiles_min_zoom = 11

• min zoom level for ge superoverlay

tiles_max_zoom = 17

• max zoom level for ge superoverlay
