and that's all I'm saying,really.Whichever way,at this stage,for these peculiarities,it's no big deal to create a kap(onlytakes a minute),download,and have a look.

Processed all charts with status:
+ 'Rectangular, doable'
+ 'Rectangular, partly doable - rectangular insets'
+ 'Rectangular, partly doable - non-rectangular insets'
+ 'Rectangular, not doable in Phase 1 because of special PLY's needed'
+ 'Chart done, checked and locked'
'processed' is the number of charts processed
'evaluated' is the number of processed charts that didn't get skipped
'pxhoriz' compares the lengths of the N and S edges, which should be equal
'pxverti' compares the lengths of the E and W edges, which should be equal
'pxsquare' compares the lengths of the NE-SW and NW-SE diagonals, which should be equal
'ratio' compares the aspect ratios of the REF point rectangle and the projected corner
+ coordinates, which should be equal
All those 'shoulds' are assuming a rectangular chart area in mercator projection.
'>n*sd' charts are greater than n standard deviations from the mean
'>5*sd' should be none
'>4*sd' should be none
'>3*sd' should be 3/1000 of the charts processed
All those 'shoulds' are assuming a normal distribution.
'censored' are outliers previously checked and looked 'okay',
+ there may still be a problem with data entry, or the chart may just be crooked.
'notmercator' are charts that aren't mercator or unknown

checked and good:
14003 - input good (large, small-scale, oldish chart)
21182 - input good (ancient chart)
24311 - input good. Obviously a skewed chart, based on the corner calibration pixel values
24319 - input good. Obviously a skewed chart, based on the corner calibration pixel values
26001 - input good
36005 - input good
37441 - input good

checked and corrected:
18766 - corrected datum adjustment (changed westward to eastward). Else all OK
22036 - corner calibrations corrected (a few pixels)
24381 - minor adjustment to corner calibrations. Otherwise good. A physically large chart.
29123 - minor adjustment to corner calibrations
42740 - adjustment to corner calibrations
43340 - correction to corner calibration (calibrated on the wrong line)
44187 - 3 corner calibrations very off. Corrected.
44342 - one corner calibration very off. Corrected.

For these charts (as previously), I've checked all inputs (not just the geodetic data that recri is querying)

checked and good:
63354 - input good
72050 - input good (chart is subject of discussion about datum corrections in this thread)

checked and corrected:
51022 - minor adjustments to CCs
51150 - CCs adjusted
52160 - minor adjustments to CCs (soundings datum corrected too)
53091 - single pixel adjustments to CCs (possibly brower disparities)
53203 - one minor CC adjustment (SW)
53266 - single pixel adjustments to CCs
53287 - adjustments to CCs (poor interpretation of the extra thick black corner markings)
53290 - adjustments to CCs (poor interpretation of the extra thick black corner markings)
54085 - single pixel adjustments to CCs
55001 - adjustments to CCs (poor interpretation of the extra thick black corner markings)
56190 - single pixel adjustments to CCs (possibly brower disparities)
57220 - minor adjustments to CCs
61190 - adjustments to CCs (poor interpretation of the extra thick black corner markings)
72142 - minor adjustments to CCs
72143 - minor adjustments to CCs. I've copied a datum note on the chart into the comments field. For possible action?

92200 - calibration input good, but added datum adjustment. Could someone check I've got it right?

93032 - single pixel CC change
96381 - input good
96580 - minor adjustments to CCs

-----
Processed all charts with status:
+ 'Rectangular, doable'
+ 'Rectangular, partly doable - rectangular insets'
+ 'Rectangular, partly doable - non-rectangular insets'
+ 'Rectangular, not doable in Phase 1 because of special PLY's needed'
+ 'Chart done, checked and locked'
'processed' is the number of charts processed
'evaluated' is the number of processed charts that didn't get skipped
'pxhoriz' compares the lengths of the N and S edges, which should be equal
'pxverti' compares the lengths of the E and W edges, which should be equal
'pxsquare' compares the lengths of the NE-SW and NW-SE diagonals, which should be equal
'ratio' compares the aspect ratios of the REF point rectangle and the projected corner
+ coordinates, which should be equal
All those 'shoulds' are assuming a rectangular chart area in mercator projection.
'>n*sd' charts are greater than n standard deviations from the mean
'>5*sd' should be none
'>4*sd' should be none
'>3*sd' should be 3/1000 of the charts processed
All those 'shoulds' are assuming a normal distribution.
'censored' are outliers previously checked and looked 'okay',
+ there may still be a problem with data entry, or the chart may just be crooked.
'notmercator' are charts that aren't mercator or unknown

Re: Charts II: NGA - 2700 Charts

72201 is the second chart I've seen where a meridian line close to the edge was mistakenly picked as the edge. I've fixed that problem, but the chart is pretty crooked whether you pick the edge or the lng line.

Someone with better skills than I should try interpolating the SW longitude on this chart. But the W chart edge is much less vertical than the E edge, so it may be that it's as good as it can get.

Re: Charts II: NGA - 2700 Charts

I got a really annoying problem with the charts 2303 and 23145 : When i move ns or ew the charts do not move at the same rate than the other ones (see attached images). It looks to me like a scaling problem. I am in quilting mode with cm93 as "background", but it is exactly the same with other bsb charts as reference. I doublechecked every entry and all seems ok for me.

Could someone have an independent lookout and tell me if he sees the same problem ?

23145 works just fine for me. Are you sure you have the latest version?

Re: Charts II: NGA - 2700 Charts

I don't know if the planned method for processing chart insets is going to be recursive, but chart 43040 has two insets, one of which has its own inset, i.e. an inset in an inset
