[Dhsvm-users] Rainymask or Rainymasks

[Keith Norman Adams]

Dear Enhao and other DHSVM Modellers,

1.  Use 'rainymasks'(with NODATA converted to 0) only for converting the
mask fine to binary.
    Use 'rainymask' (with NODATA values) for creating the stream network.

[I have used the names '...mask0' and '...mask' so I don't get them
confused]


2.  I can't help with this one.

'createroadnetwork.aml' should delete your existing 'temp.map.file', and
type out a message saying it has done so.
It should then continue, and pass the name 'temp.map.file' to
'streammapfile.aml' [==roadmapfile.aml] as the 'outfile' name.

see the code near the end of the 'createroadnetwork.aml' file:

***
&if [exists temp.road.map -FILE] &then
  &if [delete temp.road.map -FILE] = 0 &then
    &type temp.road.map file successfully deleted
  &else &type unable to delete temp.road.map file
&else &type old temp.road.map file doesn't exist

&run roadcut outcover EFFWIDTH HYDWIDTH HYDDEPTH CUTSLOPE EFFDEPTH
&type running roadmapfile
&run streammapfile outcover %roadnet% temp.road.map EFFWIDTH CUTDEPTH
RDASPECT
***

Yoou could try renaming your 'temp.map.file' (if you want to keep it)
and then re-run 'createroadnetwork.aml'


3.  I don't know the significance of a 'large' or 'negative' value like
-9499.0498, but it looks bad to me (9 km ?).


Regards,
Keith Adams.

Shall we use the modified mask file for the rest of preparation like conversion to binary file and creating stream network? There's a discrepancy in creating stream network files when you choose to create stream coverage by using the source area. The streams coverage area is the rectangle as the dem file with NODATA=-9999, or the real watershed shape as the mask file if NODATA=0.
