An update on HRSC digital terrain model coverage I missed in the dissertation

Here is another report, this time finding either where there was partial coverage of a Souness glacier-like form in the tile I manually assigned to it in my dissertation work, but full coverage was available in another tile, or where there was no HRSC tile assigned but there is either partial or full coverage available.

This is defined by the HRSC footprint containing the outline of the extent of the Souness glacier-like form, which I found out using the GDAL/OGR Python API (cookbook) using the Intersects and Contains methods of the Geometry class.

I have just output this in plain text, but the objects can be found in http://taklowkernewek.neocities.org/mars/sounesstoptrumps_js.html.

Since the processing of each tile is a bit fiddly since I didn't write the processing pipeline in the most logical way, I also check whether the tiles that cover the objects are already used in the dissertation, which is much easier to implement.

Souness 7:
Has partial coverage in [u'H1429_0000_DA4']
Tile used in dissertation was H1429_0000_DA4 with resolution 75.0
(Complete coverage, resolution) is available in [(u'H5365_0000_DA4', 100.0)]
Tiles already used in dissertation: [(u'H5365_0000_DA4', False)]

Souness 60:

  • The coverage in h1395 is almost complete for Souness 572.

  • overlap with h2681 is fairly marginal

(Complete coverage, resolution) is available in [(u'H1887_0000_DA4', 250.0)]

  • This is a choice between a fairly good (about 2/3) overlap at 50m resolution, and complete coverage at 250m. I am inclined to retain the higher resolution tile (see S986) on the Top Trumps page.

Souness 1047:
Has partial coverage in [u'H0248_0000_DA4']

I have now updated the Top Trumps page for the Souness objects that have full coverage in another tile, including Souness 60, 64, 66, 326, 414, 689, 717, 718, 1047, 1048 and 1112.
