Log Message:
GeoTIFF represents an effort by over 160 different remote sensing,
GIS, cartographic, and surveying related companies and organizations
to establish a TIFF based interchange format for georeferenced raster
imagery.

This library is the reference implementation for reading and writing
GeoTIFF tags.

Note that you need a buildlink3 file for misc/proj in order to be able
to use this.  I have submitted a PR to NetBSD pkgsrc, but until then
'cd /usr/pkgsrc/misc/proj && createbuildlink -3 > buildlink3.mk'
should suffice, given that you have pkgtools/createbuildlink installed.
