Fix ortho metadata file for IKONOS imagery #85

Closed dannyim closed 3 months ago

dannyim commented 3 months ago

When I try to run pgc_ortho.py on ikonos imagery, the xml file that gets generated does not include the xml from the original image.

Here is one example:

<?xml version="1.0" ?>
<IMD>
        <PGC_IMD>
                <VERSION>imagery_utils v2.1.3</VERSION>
                <PROCESS_DATE>10-Jul-2024 23:31:40</PROCESS_DATE>
                <ORTHO_HEIGHT>TanDEMX_PolarDEM_90m.tif</ORTHO_HEIGHT>
                <RESAMPLEMETHOD>near</RESAMPLEMETHOD>
                <STRETCH>rf</STRETCH>
                <BITDEPTH>Byte</BITDEPTH>
                <FORMAT>GTiff</FORMAT>
                <COMPRESSION>lzw</COMPRESSION>
                <EPSG_CODE>3031</EPSG_CODE>
        </PGC_IMD>
        <SOURCE_IMD>
                <SOURCE_IMAGE>IK01_20091214133200_2009121413324560000011614341_po_389987_msi_0000000.ntf</SOURCE_IMAGE>
                <VENDOR>GeoEye</VENDOR>
        </SOURCE_IMD>
</IMD>

The xml from the original image should be under IMD/SOURCE_IMD/IMD

I found that the match performed here fails, and this is due to this regex not matching the filename IK01_20091214133200_2009121413324560000011614341_po_389987_msi_0000000.ntf since the sensor part of the filename is uppercase.

I resolved the issue by updating the regex so that it is case insensitive.
