Just to be sure you mean surface area? If the DTM has hydrology removed you could count null cell values or whatever the common value for that water body is? That DTM may also have a large temporal resolution. Better yet grab some multispectral imagery and run hydro detection band combos on it, turn to polygon then find Shape_Area. ... View more

Hi George, I've only used these cubes as inputs for geostatistics not visualisation (I can see visualisation tools are now in pro which i'll need to have a gander at), but I'm pretty confident they're not intended for use in this manner (i.e. data from single station). Also each cubelet is designed to have a magnitude, rather than a kind-of 3d graph which I believe you are envisaging. ... View more

I'll need to read up on the o'l space-time cube again but I thought there was only 1 temporal element transferred as a z-axis value, x ad y are spatial and the magnitude of pressure etc is stored as the cube value? I don't see how you can map the julian day in x or y without destroying any spatial relation? Can you just use a datetime as input? ... View more

Bit of a stumper actually, I might just add a new field and run a field calculator expression on it to return 0 or 1 or something like that. then select by attributes where the new field = 1. #pre-logic python def checker(PIN, PIN_TRACKING):    if PIN IN PIN_TRACKING.split(","):        result = '1'    else:        result = '0'    return result #window checker(!PIN!, !PIN_TRACKING!) ...

Hi Michael, We're on fat client home laptops, connecting via NetMotion VPN, ArcGIS is using concurrent licensing which I believe is enabled through FlexNet to a licensing server, no-one is using RDP as far as I know except for server connections.  This networking side of things is definitely a weakness of mine. ...

Those extent objects can be a bit tricky, I might amend it to something like: #create a copy of extent object to modify new_extent = objDes.extent #set values for extent object new_extent.XMin = objDes.extent.XMin new_extent.XMax = objDes.extent.XMax new_extent.YMin = objDes.extent.YMin new_extent.YMax = objDes.extent.YMax return new_extent No idea if that will work as I struggle with these also.  You may just want to run the 'Feature envelope to polygon' tool on the data then use that polygon as the extent if not. ...

Thanks Michael Editing for the features is said to be very slow for both SDE and FGDB and shapefiles (FGDB and Shapefile on various Network Shares).  I'm new to the current Organisation and only been working-from-home so unfortunately can't give any good feel for the pervious performance, although some users have indicated their was a large drop-off near the start of the year (though we have as-yet been unable to narrow-down any root causes) The bulk (if-not all) of users are now connecting to the Network via VPN which is hardly going to improve performance (slow editing and data access was highlighted before working-from-home). No smoking gun has been found unfortunately. I guess another question is why does an entire workspace become editable when you might only want to edit one feature out of 100? Surely making those other 99 (could be more) editable and locking them out is not going to be good for performance. ... View more

Hi Rana, 1. - enable editing by right-clicking on the feature in the table of contents --> edit features --> start editing 2. - the editor toolbar should then be active if you don't already have the toolbar, if it still hasn't appeared, right click on some grey space at the top and select the editor toolbar. 3. -the first tool on the editor toolbar looks like an arrow with its tail cut off, select that, then select your feature in the map with it, it should then be highlighted. now you can select and hold down the left mouse to drag your feature to a new location. 4. on the editor toolbar dropdown click 'save edits' then 'stop editing' Note any coordinates you have as attributes will not change, they have no relation to your actual feature coordinates when they change.  to update a field like this, start editing again and type in the new coordinates, or you can right click on the attribute table field and select 'calculate geometry' (I think that's the name but not 100 percent) or something similar. good luck. ...

The point density tool utilising a population field would kind-of replicate what you intend, but not really. From what you're saying, a kernel density would not be appropriate as it would diminish over distance. for any large number of points this would probably become intractable. i.e. what about points 21 miles the opposite direction to the point 20 miles way? What about points 10 miles from the other point? My best advice would be to choose the maximum distance you wish points to have an effect on the surface (e.g. 20 miles cutoff), use that as the search radius and use the population value from your intensity field. ...
