The attached zip file contains a Python script tool that calculates zonal mean aspect azimuth, and mean aspect class. The syntax for the fundamental calculation is: math.fmod(360 + (math.atan2(!MeanSin!, !MeanCos!)) * (180 / math.pi), 360) ... View more

In this case, param[0] is the input raster, param[1] is the input raster's RECLASS field (the field has a dependency on the input raster), and param[2] is the REMAP control itself (has a dependency on both the input raster and on the reclass field). Having said that, I'm still at 10.0, so have not had an opportunity to validate that this (or something like it) works in 10.1. ** For some reason, the indents aren't showing up in the ToolValidator code below... def initializeParameters(self): """Refine the properties of a tool's parameters. This method is called when the tool is opened.""" self.params[1].value = "VALUE" self.params[1].enabled = False self.params[1].parameterDependencies = [0] self.params[2].parameterDependencies = [0, 1] return ...

A colleague of mine reports that at 10.1, adding the two parameter dependencies to the remap element under initializeParameters in ToolValidator (instead of updateParameters) was all that was needed to activate the �??Classify�?? and �??Unique�?? buttons and populate the remap table listing.  So, there does appear to be hope on the horizon... ...

OK, another rookie mistake on my part. I'd been using the datasetType property without success, but the dataType property of os.path.dirname(feature class) distinguishes between a Folder, a Geodatabase, and a Feature dataset...which is what I needed. Thanks to Wayne and Jake for nudging my pea-brain in the right direction... ... View more

RafealR, did you ever resolve how to populate the remap value table automatically? ... View more

Another option is to create a topology rule for "must not have dangles", and then mass TRIM and EXTEND from the Topology Error Inspector using a reasonable search radius.  TRIM and EXTEND will insure original directionality is preserved.  Planarize lines if an actual intersection (split line) is required. ...

No, I was unable to work it out.  The two forms, one running against a shapefile and the other running against an AXF file, produce different results even though their code is identical.  It is mysterious and disappointing... ... View more

Quite right.  The IDENTITY tool would do the trick, and quite rapidly.  Thanks. On a more rhetorical level, however, I'm curious why my script has run successfully on 6 or 7 occassions in 9.2 (on the same PC, using the same dataset) but fails in 9.3.1. ... View more

Whenever I upgrade, I copy my data folders to an SD card and then reset the device back to factory defaults...essentially re-imaging the device back to its original factory state.  Yes, it takes about 15 - 20 minutes to reload my device applications, but I'm always insured of a clean install. ...

Just curious, why are you using a text field ("01") instead of a numeric field (1) to represent numeric quantities? ... View more

Something else to consider in the GPS Analyst vs Pathfinder Office debate is (I'm pretty sure) that GPS Analyst does support ArcPad Checkout/Checkin to versioned SDE geodatabases. ... View more

I created a QuickProject, and an AXF checkout.  I added a "Get X Coord" button to each of the edit forms.  The button's On Click event calls: MessageBox "The X coord is " & EditForm.Fields.Shape.X The AXF form returns a zero.  The QuickProject form returns a legitimate X coord.  See attached images. I don't know why the two forms produce a different result even though their code is identical. ... View more

A new wrinkle has developed. The code MessageBox EditForm.Fields.Shape.X returns a legitimate X value when called from the OnLoad event of a point shapefile's form .apl that was created as a QuickProject. However, the identical code called from the OnLoad event of an AXF point layer's form returns a zero. Perhaps shapefiles and AXF layers don't behave the same way? ... View more
