@ -51,55 +51,59 @@ makes it easier, if one point is found to be in error, to work out which ones

were derived from it and will therefore also be wrong.</p>
|

|

<p>As far as we are aware, all of these points which we have visited are
|
||||
correct, with the exception of 7/11 on the col (ie. the most useful point,
|
||||
nearest Top Camp), which seems to be out by an angular error of 25 or 26°
|
||||
from the Nase point. In the table, point 14/16 is also noted as possibly
|
||||
being dodgy, but we have no real indication of why.</p>

correct, with the exception of 7/11 on the col between the SMK ridge and
|
||||
the Nase (not far the old Nase Top Camp), which seems to be out by an angular

error of 25 or 26° from the Nase point. In the table, point 14/16 is also

|

|

<p>Expo (and indeed, the kataster) has now moved over to using the same system as
|
||||
the rest of the world, ie. UTM based on the WGS84 datum. So it is unfortunate that
|
||||
the points in the table below haven't been translated (and neither, it seems have
|
||||
the ones in the survex files). Various people at various times have located the points
|
||||
with GPS, and those fixes I've found are also included here in UTM zone 33T form.</p>
|
||||
<p>This table shows the coordinates of the laser points in UTM using the WGS84
|
||||
datum, which is the coordinate system we now use for the expo dataset (and
|
||||
which the Austrian's kataster also now uses). If you want the original
|
||||
coordinates, see the <i>*fix</i> commands in the file fixedpts/laser.svx
|
||||
in the Survex dataset.</p>

<p><img src="../../../icons/roadwk.png" class="icon" alt="" />A description of our own

surface surveys in the area is under construction, and should eventually

include details of how to find these laserfound points and other fixed

points. Currently, locations of caves in the kataster may be quoted as these

coordinates, or as Latitude/Longitude derived from the Austrian Alpine Club
|

(OAV) map sheet 15/1, which does not have a grid. Trying to get all these

locations into a single coordinate system is a priority, but will involve
|

quite a lot of unglamorous surface surveying, so don't hold your breath...</p>

<p>In some Austrian literature, the easting quoted is in a system labelled

BMN. The Easting grid line +36000 (Gauß + Krüger, M31) is the

same as BMN 486000, and translation appears to be a matter of simple
