jrsrpname

A Python implementation of the QVF file-naming convention for large satellite imagery archives, as described in:

Provenance

jrsrpname is an independent reimplementation, built from the naming-convention description published in the paper above. It is not a port of, and shares no code with, any existing implementation.

The author has prior familiarity with an existing closed-source implementation of this convention (also referred to as qvf.py), whose copyright ownership is not clearly established. To avoid any ambiguity about derivation, jrsrpname deliberately uses a different name and a different internal design, and was written directly from the published paper rather than from that source.

Most of the implementation was written with the assistance of Claude (Anthropic). Unlike the author, Claude was never given, and did not access, view, or otherwise reference qvf.py or any other prior implementation of this convention at any point -- its only source for the naming/parsing specification was the published paper above, fetched directly from figshare.

Installation

python3 -m pip install jrsrpname

Usage

Usage follows closely to that as described in Flood, N. and Danaher, T. (2013), but uses a more object oriented approach. The basic approach is to parse a string representing a QVF filename:

from jrsrpname import QVFName
name = QVFName.parse("l5tmre_p090r079_20090914_dbgm6.img")

The name will then have as members the described what, where, when, processing, suffix components:

print(name.what)
# l5tmre
print(name.where)
# p090r079
print(name.when)
# 20090914
print(name.processing)
# dbgm6
print(name.suffix)
# img

Modifications to any of these are done with the replace method:

newname = name.replace(where='qld')
print(newname)
# l5tmre_qld_20090914_dbgm6.img
