Node elevations are assigned spatially using the index WshdPts.txt file
available at:
\\cassio\modeling\Model_Programs\Emgaats\CodeV2.2\NodeTool\data\WshdPts.txt
The index file WshdPts.txt should contain a list of elevation files used to
populate
the node ground elevation. Negative or odd values populated into mdl_nodes are
originating in the source data specified in WshdPts.txt, and these files should
be
investigated.

Thank you. The problem coming up is due to alternatives being placed too close
to
the river, too close to have any proper elevation data.
Will forward a request to generate nonzero river elevation area data to Albert.

It appears that the problem is caused by unavailability of elevation points in
certain areas. The elevation of a manhole/node is extracted from point files as
described by JohnB and ArnelM in previous messages. Arnel has provided me with
a
definite node number(ABL496) that was causing the same problem. Further
checking
showed that this node is an outfall and located in the river area. Majority of
the
point files cover most of the modeling system extents and have been patched
from
time to time when needed. The patch for this area has been fixed(see attached
figure). If you need to check elevation points availability please load the
seamless
Mapinfo table:
\\Cassio\gis1\MI_DATA\ENVIRON\TOPO\GRD\2004\PtsTbl\ALLDemPts.TAB
Further, if you have an alternative/model that needs some patching for
elevations,
please let us know so we can address those appropriately. Furthermore, please
take
note that some of the future patches might need qa/qc since they have been
derived
from sources that require scrubbing/verification.
