Fill Tool is not working

AliAmeli — Tue, 04 Feb 2014 02:47:31 GMT

I am trying to fill the depressions. However it seems fill tool is not working, since cut fill generated raster file is displaying zero for all volumes. In addition when I am applying sink tool over the filled DEM, I would end up with the same number for unfilled DEM, Although I have to expect zero for the number of sinks after filling.
Note that the surface I am working with has a high slope of 13%
Any recommendation on why the fill tool is not working?
Thanks

Check your processing extents and make sure your raster area is covered by it.

Thanks Mark
I have checked it out. It is still not working.
Attached is the DEM file I am working on. I highly appreciate it if you could please check it an see if fill tool is working.
It is a very small domain but since it has a large slope I have a feeling that fill tool is not working.
Thanks a lot in advance

Ali,

I created a raster from the xlsx file. When I run the fill tool on it, it runs fine. It also has not cells to fill since there is not local low point that is not on the edge of the raster. I'm running 10.1 and ran the fill tool in both Arc Hydro and Spatial Analyst.

Dear Mark
Thanks a lot for your cooperation.
As far as I have understood form your analysis, no depression has been filled. It is exactly what I have obtained. However when you are applying sink tool you would see there are several identified sinks in the domain. So why are not they being filed?
What I am going to do is obtaining (for each node) the height above which overland flow is initiated. That is why I am using this tool and I am not going to use fill tool as a pre-analysis of overland flow. I Just need the mention heights for each node.
any recommendation?

Again thanks a lot for your consideration and devoting time

I rarely run the sink tool. I tried to run it and got an error (wouldn't even start to run). Then I realized the the input file is not the DEM but the fdr (flow direction grid). When I used the flow direction grid, it showed a raster range from 0 to 255 with all values "null".

So, unless I created the DEM incorrectly, the sink tool is giving me the same answer I get other wise. The way I identify the sinks is I use the raster calculator to subtract the rawdem from the fil dem. I can then color ramp it with dark blue for the high value (deep) sinks and a lighter blue for the shallower sinks. In your dataset I still find no sinks.

Dear Mark
You are totally right. There is no identified sink in the domain.
If you have flow direction file, please have a look on its value. Mine shows just 64 that is kinda weird. According to the ARCGIS help
64 means flow from down slope to up slope. It is also impossible to have just one flow direction. According to DEM, you can easily figure out there should be more than one flow direction for all points.

Please accept my apologies for bothering you again.
Cheers,
Ali,

According to the ARCGIS help 64 means flow from down slope to up slope.

64 means the flow is to the north. (See image). The only other number I know of that is not shown on this graphic is 255 which defines the cell as a sink. See also http://webhelp.esri.com/arcgisdesktop/9.2/index.cfm?TopicName=flow_direction

How can I obtain north direction for my model?Is there any default in ARCGIS?
As far as I understood from your reply, it should be only one flow direction for this case (north direction). However it is almost impossible to have only one flow direction because of the irregular surface in my case.
Dont you think there is something wrong with it?
Thanks

Ali,
I believe up on the screen is default for Arc Map is north.

To check this issue, I had to convert the data to create the DEM the way I know how. There were some negative lat/long valuse that I changedBelow is a jpg of my work on the DEM you sent in xlsx format. I assumed a 10'x10' cell size (but that shouldn't matter for checking direction).

Format you sent it in:

          Lattitude   Longitude   Bedrock
       -2   48   12.5179
       -1   48   12.4755
       0   48   12.4015
       1   48   12.2358
       2   48   12.124
       3   48   12.1508
       4   48   12.2076
       5   48   12.179
       6   48   12.2155
       7   48   12.244
       8   48   12.2862
 .
.
.

Format I converted it to:

NCOLS 29
NROWS 51
XLLCORNER 290
YLLCORNER 510
CELLSIZE 10
NODATA_VALUE 0
12.5179
12.4755
12.4015
12.2358
12.124
12.1508
12.2076
12.179
12.2155
12.244
12.2862
.
.
.

This is the resulting flow direction grid. The red lines are flow trace paths using the Arc Hydro flow trace path tool. all the paths flow south (down).

Dear Mark
I was just wondering if you know how can I export TIFF image from raster file along with its legend?And how can I add axes to the scene?
Thanks a lot

Go to layout view. Add the legend and organize the layout as you want it. Go to "File>Export" and choose the format you want to export to, etc. My license is down and so I can't verify this process right now, but I'm pretty sure that should work. This will be an image for sharing (like I did in this thread), it will not likely be good for Arc Map data or be georeferenced. I think if you do the export from data view, the image might be georeferenced, but you won't get a legend since that only works in layout view. I suppose you could screen capture the legend and paste it into data view if you want the data part to be georeferenced and have the legend also.

Dear Mark
And how can I add axes to the scene?

That would be a graticule, which is a property of the data frame. (Go to layout view/ right click your map/ Properties)
