[GIS] Converting xyz batch to ESRI grid format using XYZ2GRID 2.1 – batch problems

arcgis-9.3arcgis-desktopbatchconvertesri-grid-format

I am trying to use Min-Lang Huang's XYZ2GRID2.1-Batch program downloaded from ArcScripts and I keep getting the error

C:\users\public………..xyz Error-Object required

Does anyone know what the problem is? I have created an empty ASCII folder and an empty GRID folder and all the rest of it but not sure what the problem is. Does this script need to sit anywhere special? How does it know that my spatial extension is activated?

I am using ArcGIS Desktop 9.3.1 and Windows Vista.

I remember using that tool, helped me a lot, but did not personally have any problems with it, so cant help with your error.

Other than Jakubs response above, can you not just run the Ascii to Raster tool in batch mode, direct from ArcToolbox?

Sounds like you're wanting to do this in batch (don't blame you)

As STH said, looks like Global Mapper will indeed do batch conversions. Nice price as well.

FME Desktop can do using the RasterDEMGenerator transformer and a bit of linking with reader/writer, but you'll need the Pro version, not available in the ArcGIS Data Interop extension.

If free is more in your budget, gdal_grid should do it. You'll have to spend some time figuring out the extents of all your xyz files, but ogrinfo will make short work of that, and then writing a batch file/script to run it over each file.

Or you can use ArcGIS ASCII 3D to Feature Class (requires 3D Analyst) chained with Point to Raster, as described here and then batchify the process with ArcPy or ModelBuilder. If you don't have 3D Analyst, you can use any number of arcscripts or LASTools txt2Las and las2shp to get it in a format ArcGIS can work with. I know you didn't want to convert the txtfiles to intermediate feature classes but this isn't too labor intensive, and you already have access to the software.

[GIS] Dealing with empty feature classes in a ArcGIS 9.3.1 Python script

I've run into that error a lot. Depending on how your script is setup to process each feature class,ie if it processes each one at a time you could try using a search cursor test. See below.

EDIT:

The search cursor in this case is looking at the first shape record of each feature class and seeing if it has a null value. If its null, then the feature class is empty because the shape can't be null as far as I know. Try this for your code:

REVISED CODE:

for iter in cop_dictionary:                                     
    path = part_path + iter + ".shp"   # I think all you need is iter here,
                                   # since the for loop handles the iteration
    rows = gp.SearchCursor(path)
    row = rows.next()

    value = row.Shape  #or row.SHAPE capitalization matters here!


    if value is None:
        #move onto next feature class
        gp.AddMessage(iter + "Is Empty")

    else:
        #copy feature class

        gp.CopyFeatures_management(iter, path, "", "0", "0", "0")                       
        gp.AddMessage(iter + "has been exported") 



    del rows, row
