[gdal-dev] Relating to GeoLocation tool of Geospatial PDF Document

[Vankadara, Sunil]

Hi Team,

I created a PDF file with OGC_BP as GEO_ENCODING option like shown in the  below command.  The below tif file's Datum and Projection details are WGS84 /Geographic (lat/lon).

./gdal_translate.exe -of PDF ../../Data/input/sample256x256_1.tif ../../Data/output/sample256x256_1.pdf -co GEO_ENCODING=OGC_BP -co COMPRESS=JPEG -co PRODUCER="ERDAS IMAGINE" -co CREATION_DATE=D:20150407111345+02'00'

Looked at the created PDF file Metadata using QGIS tool and noticed that it is having the same datum and projection details as like below.

Layer Spatial Reference System
+proj=longlat +datum=WGS84 +no_defs
Layer Extent (layer original source projection)
-84.5046451524118538,34.1200924180016969 : -84.5042907999925177,34.1204467704210259

When I tried to use the Geospatial Location tool (Edit->Analysis->Geospatial Location Tool ) in the Adobe PDF Reader then the empty lat/long values are displaying at the right bottom of the  document.
Am I missing anything in creating the Geospatial PDF document ? How to confirm whether the CRS information is written into the PDF document or not?
How GDAL PDF handles in case the given projection is not supported by the driver?

Regards
Sunil
