Translate GeoPDF to GeoTIFF using GDAL
Used to convert a Topo GeoPDF to a Tiff image with customizable outputs with gdal_translate.
Examples
Simple
- $ gdal_translate topo_map.pdf output_topo_map.tif -of GTiff
- gdal_translate: A command line utility provided available when GDAL is installed.
- topo_map.pdf: The path and filename to an existing Topo GeoPDF from which the export is derived.
- output_topo_map.tif: The path & filename of the to be created GeoTiff which is derived from the topo_map.pdf.
- -of GTiff: The option GDAL uses to know the desired output format of the translated Topo GeoPDF.
Custom Layers
Create a map with just the vector data and no labels. See pdfinfo to get all Topo GeoPDF layers.
- gdal_translate topo_map.pdf output_topo_map.tif -of GTiff --config GDAL_PDF_LAYERS "Map_Collar,Map_Collar.Map_Elements,Map_Frame,Map_Frame.Projection_and_Grids,Map_Frame.Structures,Map_Frame.Transportation,Map_Frame.Transportation.Road_Features,Map_Frame.Transportation.Trails,Map_Frame.Transportation.Railroads,Map_Frame.Transportation.Airports,Map_Frame.Hydrography,Map_Frame.Terrain,Map_Frame.Terrain.Contours,Map_Frame.Woodland,Map_Frame.Boundaries,Map_Frame.Boundaries.Jurisdictional_Boundaries,Map_Frame.Boundaries.Jurisdictional_Boundaries.International,Map_Frame.Boundaries.Jurisdictional_Boundaries.State_or_Territory,Map_Frame.Boundaries.Jurisdictional_Boundaries.County_or_Equivalent,Map_Frame.Boundaries.Federal_Administered_Lands,Map_Frame.Boundaries.Federal_Administered_Lands.National_Park_Service,Map_Frame.Boundaries.Federal_Administered_Lands.Department_of_Defense,Map_Frame.Boundaries.Federal_Administered_Lands.Forest_Service,Barcode"
- --config GDAL_PDF_LAYERS: The config option which takes a list of comma seperated map layers to be added to the created tiff.
With Compression
- $ gdal_translate topo_map.pdf output_topo_map.tif -of GTiff -co COMPRESS=DEFLATE
- -co: An option GDAL uses for the GeoTiff creation options.
- COMPRESS=DEFLATE: A -co value to tell GDAL to compress the tiff using a deflate algorithm.
- Default: NONE
- Available: JPEG, LZW, PACKBITS, DEFLATE, CCITTRLE, CCITTFAX3, CCITTFAX4 or LZMA.
