Converting to DSS

CynthiaErhardt

I am trying to convert raster layers into DSS files to be used in the HEC-HMS models. The tool in arcHydro converts time series layres into DSS files, not raster layers.

Is there a program or method to convert from raster to DSS?

Thank you.

hi Ferat Çağlar,did you find a solution? I used: asc2DSSGrid INPUT=pre_19700101.asc DSS=Pre.dss PATHNAME=/UTM36/Ceyhan/Precip/01JAN1970:0000/01JAN1970:2400/PROJECTED/ GRIDTYPE=UTM ZONE=36N DUNITS=mm DTYPE=PER-***

but I didn't see any dss file?

any help

many thanks

Sorry for the late response. I do not have experience in what you are doing.

Sikanar,

I have not converted raster data to dss before, so I don't think I can help you. Sorry.

Hello,

I'm having difficulty while trying to convert ascii to dss. I'm using asc2dssGrid.exe tool in order to do that.

below is my command line input

asc2DSSGrid INPUT=pre_19700101.asc DSS=Pre.dss PATHNAME=/UTM36/Ceyhan/Precip/01JAN1970:0000/01JAN1970:2400/PROJECTED/ GRIDTYPE=UTM ZONE=36N DUNITS=mm DTYPE=PER-CUM

and below is the header file of my ascii input

ncols 40
nrows 45
xllcorner 571919.145856
yllcorner 3926307.6104104
cellsize 10000
NODATA_value -9999

and below is the output of command line output of asc2dssGrid.exe

= = = GridInfo = = =
gridType: UNKNOWN
infoSize: 124
gridInfoSize: 124
startTime: 7 January 1970, 00:00
endTime: 7 January 1970, 24:00
dataUnits: mm
dataType: PER-CUM
lowerLeftCellX: 0
lowerLeftCellY: 0
numberOfCellsX: 40
numberOfCellsY: 45
cellSize: 10000

It appears to be reading grid values correctly since I get the max min values same as my input. However, definitions of gridtype and LowerLeftCellX-Y are wrong (0 in this case) or remain as UNKNOWN.

Any advice is appreciated!

Hi Sikandar Ali !

Did you find a way to do the conversion?

I have prepared CN grid on arcgis (using HEC-geoHMS) but I can t find a way to convert raster to HEC-DSS..

Hi Mark,

If you can tell me how to create SHG grid for other projection rather than Albers Equal Area Conic that would be really helpful.

Hi,

I am trying to import TimeSeries data from DSS to GDB. It works fine, but I would like to import data such STORAGE which is undefined in ApUtilities Framwork Config XML. I added STORAGE variable and connected UNITS to XML. Tool works, but output is empty. Please, do You have any experience with importing/exporting undefined. Is possible to do it so simply?

I am using ArcGIS 10.2.1 with lastest ArcHydro, GeoHMS and HMS.

I inserted that: "<Variable Name="STORAGE" CPART="STORAGE" DTYPE="INST-VAL" />" and "<Unit Name="1000 m3" DSSUnit="1000 M3" />"

Thank You for Answer!

I've had success using DSS utilities that I found via http://www.hec.usace.army.mil/software/hec-dss/hecdss-commandpromptutility-intro.htm. However, I was automating the import of rain data into DSS. For example, the DSSTS (time series) tool worked well once I understood it. I was able to create a batch and python code to do all I wanted.

Maybe they have a tool like that to do what you want.

You also might want to look into Geo-HMS to see if it has tools to do what you want to do. This works inside ArcMap (though I don't know if they've updated to 10 yet).
