I want to create a model builder using ArcGIS 9.2.

I have one big 10m DEM that needs to be cut into pieces by using Quad 12k layer . I have these individual 12k quads in my file geodatabase and they are 338 layers.

I want to use "Extract by Mask" to clip the DEM and then rename them to name each quad name.

Could I do this ? I tried to do this way and i am not getting what I want. Does anyone out there tell me a better way ?

Thanks,
Robert

You can try using the Split tool (Analysis Tools>Extract>Split) to do the job. It will also name the individual split files as per the Quad name.

I didn't know it works with raster too (I'm very happy to know that! ), but that's what I always do to split data...

The Analysis Tool with the Spilt does not apply to raster. This tool is for vector only , so I think she misunderstood me. Yes I use that split tool to break the quad line. I only need to break the raster (DEM) into quad using the quad as a mask.

Could you describe what happens/what goes wrong when you attempt to use the "Extract by Mask" tool?

The problem when you try to extract by mask for each polygon and then the output will just create one raster layer. All I want the output to create each raster using each quad.

Could you attach a schematic of your Model Builder strategy? Also, are you asking the same question on the ESRI User Forum site? While there is plenty of expertise in GIS on this site, there is much more on the ESRI site.

I have post the same question in that ESRI Support website. There should be a script or AML that allows us to do that to
clip a DEM using a quad as a mask or polygon. I know there must be a way around to do that.

Thanks
By the way, you are to north from me ! I am from Las Cruces !

Hi

Sorry for the goof up, you are right it works only for vector.

The best solution for cutting off sequential tiles (square or rectangle) from any raster (including DEM) is available in Global Mapper. It has Grid export option where one can specify pixel information or for a DEM the rows and columns information for the tiles. Since the DEM needs to be cut to a mask of 12k, it shall be sequential equal tiles. Though the naming will not be as per the 12k mask but conforming to any sequential pattern that you can choose.

It also has an overlap option too where some pixel overlap can be defined for adjacent tiles. I found this solution pretty simple and straight forward for achieving part solution of the problem.

Best..

Hate to repeat myself, but FME can do this

Clip a raster to a set of vectors and then write it out to seperate files based on an attribute from the vectors. In FME-speak, it's called a Fanout.

I think the next time I'm going to ask a question, I'm going to ask straighforwardly: "hey Hans, can we do this with FME or Manifold?" I'm gonna save us a lot of time!

I have various FME related snippets of text on hotkeys here, saves me a lot of time

Naah, just kidding. I'm trying not to sound like an advertisement here, but it is a great tool for automating GIS-tasks. In fact, I'm doing a talk on Monday at the European FME User Meeting in Münster, Germany. Subject will be how I've used FME in support of the cartographic production process. It's a presentation that sort of evolved from the one I gave at NACIS last year. I'll post it here afterwards.

Hans,
Isn't it time to just add this line to your signature?

Hello,


Finally, the model builder I have been asking fo worked ! The only thing you cannot rename it, so I will just leave at it.
Somebody from ESRI Support online helped me out. If you are interested in that, just let me know.


Happy Holidays !

We are always interested! (at least, I am! )

Thanks!
