Good to here that you have found the workaround ... View more

The list of features and their rank is stated to be a Value Table type in the help. So just create a value table in arcpy. vTab = arcpy.ValueTable() vTab.insertRow("{} {}".format("ShapeA.shp", 1)) vTab.insertRow("{} {}".format("ShapeB.shp", 2)) Then use the vTab in the Integrate tool. ...

Well the creation of the spatial index is a feature of the geodb. You can create a very long list of inputs and have them all appended together, that way the spatial index is calculated only once at the end. If you append them invidually, each time append runs the spatial index will be recalculated, which does increase processing time. Perhaps you can mess with the spatialGrid1, 2, 3 in the arcpy.env settings. Set them all to 0 and see what happens. ... View more

Have you tried to do this simply in ArcMap rather than a model. The view join doesn't seem to be active at all. It's not coloured blue. ... View more

And, if all we are referring to in this thread is how to create rasters from a las dataset use the Las To Raster tool (Thanks you to Xander for pointing this out to me a while ago). Different output cell sizes can be specified in the environments and the sample distance. Set the extent explicitly so that each raster is exactly co-registered. ... View more

Xander, do you not have a day job.... ... View more

As far as I recall you can't edit a layer with a query definition applied. If you have various categories of data you can apply that symbology and edit them individually quite nicely. If you only want to see one of your categories, just remove those categories from the symbolgy editor. ... View more

All output feature class dialogs in the tools allow you to navigate to a geoDB (file, personal or enterprise) and assign a name to your output data. Create a file goeDB or a personal one (access mdb) using ArcCatalog first. Filenames inside a geoDB cannot begin with a number. ... View more

Try to move away from shapefiles. Why not migrate your data to geodatabases instead. Are you sure that the file permissions are read/write where you are storing the shp? ... View more

What db are these polygons in? Are you sure that every record has valid geometries? Open the attribute table and do an ascending sort on the area field. Any records where area == 0? ... View more

Don't know why this post has come up now in the recent list but.... All the OSGB1936 transformations are, of course, available in ArcGIS. Don't need 3rd party software solutions, free or not free. ... View more

"I was told it cannot be done as some of the commands are only available in ArcMap." Just about everything is available through python / arcpy. So who is telling you this? Sure if you want to write customized interfaces, web stuff etc, then you need .Net, ArcObjects and all that. Tell us what you want to do, what progress you have made so far etc. There is lots of arcpy / python snippets, help out there. I am sure that the python fundies here or at GIS-SE will help with particular questions. ... View more

How fast does that go Xander.? As I understand it, you are running a search cursor over the attachment table for every oid in the primary Fc. It would probably be better to write an updating script which reads the attachment table once, stores the results in a list or dict, then looks through the fc to update. But this would not be implementable in the field calculator. But good thinking. Perhaps there is an "idea" here to make symbolization of records with / without attachments easier. ... View more
