SUM: String Manipulation

2009-11-20T10:35:15Z

Original Question:

We need to format values in a string field. These are 10 character
parcel IDs in this format - 1234567899, which we want to format to
123-45-67-899.

Summary Solution:

Almost all of the responses suggested to use field calculator with VBA
text parsing and concatenation commands. One response mentioned python
scripting and creating a tool to use in later instances. For the field
calculator operation, a text field needs to be created with the
following code applied -

Left([Field],3) & "-" & Mid([Field],4,2) & "-" & Mid([Field],6,2) & "-"
&

Right([Field],3)

Thanks to all responders, there was a huge response. Following is a list
(in no particular order):

ENCK Dave, Kyle Ostapuk, Ray Willis, Ian McGovern, Sonia Dickerson,
Brad, Layne Seely, Daniel Gluck, Jim Dahl, Jeff Jenness, Greg Burgess,
David T Hansen, Jennifer Strang, Valentina Boycheva, Nigel Pickering,
Adam Hinley, Sam Rideout, Bill Chappell, billd@..., Jim Burton,
Nico Burgerhart, Johan Baard, Michael Maddox, Dawn F. McCall, Jim Scace,

[SUM]: Line Symbol with Arrows

2009-11-19T10:53:35Z

Many thanks to the folks who answered my post with the solution. For the line symbol pick a standard "Arrow At Start" or "Arrow At End". Then under properties of that symbol I go to the "Line Properties" tab and then under the "Line Decorations" section I click on Properties. Under "Number of Positions" input the number of intermediate arrow heads you require.

That works for me.

Thanks!

[SUM * 2] Python to .DLL

2009-11-19T06:27:23Z

I recently summarized some research to see if a python script could be
converted into a .DLL file and called through a button. While it appears
that python cannot be converted to a .DLL, the script can still be run
through the use of a button control. A big shout out to Nobbir Ahmed with
ESRI who help me find this solution!

To run a python script, or any tool or model created and saved in a
toolbox, from a button - customize your toolbars, switch to the COMMANDS
tab, at the bottom highlight [UIControls] click "New UIControl", select
UIButtonControl and click "create and edit". The VB Editor window opens.
Paste the code supplied below, replacing the name of the toolbox AND the
name of the tool or script you wish to reference. Pay close attention to
your scripts actual location and name, NOT ITS LABEL. These can be got by
right clicking the tool in Catalog and reviewing the properties.

Click save in the VB editor and close it. Navigate back to your
customize>COMMANDS>UIControl, and drag the button to a toolbar location.
You can rename or change the icon as needed.

This works well - enjoy.

Bret.

Code:

Private Sub UIButtonControl1_Click()

Dim pGPToolCommand As IGPToolCommandHelper
Set pGPToolCommand = New GPToolCommandHelper

pGPToolCommand.SetToolByName "C:\gptoolbutton\TEMP_tools.tbx",
"GDBcreate"
pGPToolCommand.Invoke Nothing

End Sub

I'd like to ask for any advice on bringing CAD drawings into a subdivision layer. Does anyone have a process in place for this? What about older paper drawings? I'm thinking this has to be a manual, one-by-one operation.

We have previously depended upon our Property Appraiser's parcels layer and dissolve on subdiv code to create a countywide subdivision layer. Linework is usually good enough but data input seems to be a problem. We are after more reliability and accuracy.

How do you use a subdivision GIS layer?

[SUM] Python to DLL

2009-11-17T13:47:43Z

Summary of what i learnt - IT CANT BE DONE

From an ESRI Support Analyst I have been working with on a related issue:

You cannot directly tie in a python file to a DLL that I know of. There
might be a custom library out there that allows this but that would not be
supported by ArcGIS if there were issues with the DLL after the fact.

Why a button in the first place? You're making a tool that has a built in
form already and all the user has to do is place the Toolbox and PY file in
the same folder and they can use it all day long. Trying to make a DLL out
of a python script would be basically making this more difficult then it
needs to be and if you want to go the way of DLL then you need to get out of
the Python realm altogether and work in VB.NET or C# and create a custom DLL
for ArcGIS Desktop. Do not use VBA as it goes away after 9.4 so it's
recommended to use the other two languages. In 9.4 you can also use Java to
make an addin but that's not going to be out until next year so don't worry
about it.

And from Sai Dhalli, a fellow ESRI Listserver:

Arcmap is a .Net framework , I dont think you can add python scripts as
elements to it. They are from a totally different family. There are
certainly some ways, but not straightforward.

Solar Radiation: Grid versus ASCII

2009-11-15T17:25:12Z

Hello All: Was hoping to get help with a very frustrating little problem dealing with Solar Radiation calculation in Spatial Analyst.

My steps:
1. Calculate area solar radiation on original DEM1.

2. Convert original DEM1 to ascii file using RASTERToASCII_conversion function, producing DEM1.asc file.

3. Convert DEM1.asc from (2) right back to a raster using ASCIIToRaster_conversion function, producing new DEM2. Note that completely identical to DEM1.

4. Run Area solar radiation on (3)'s DEM2 and get order of magnitude completely different values for my solar radiation grid. (I make sure all default parameters are completely the same for all solar radiation function calls.)

I have looked at ascii file for both (1)-DEM1 and (3)-DEM2 -- the original and the converted back and they are completely identical -- pulled them in to python and did a string comparison even. Even using the describe function on both DEM1 and DEM2 shows identical raster grids...

Any help would be greatly appreciated on this problem (need to desperately work with ascii files outside of arc and send desperate list serve plead of help as last resort).
Best,

I have a fire damage dataset in point shapefile format and the center of the circles around which (i.e from 8 mile of the radii) I need to compute density of the fire damage. During density computation, fire damage points close to the center should count more than points further from the center.

Additional SUM: Removing Tools

2009-11-06T06:12:11Z

Regarding my problem with removing the tools that were installed when I tried LP360, here is the information I got from the developer. I actually had to download and reinstall the software because I had deleted the necessary files.

Tom,

Sorry the uninstall was not complete, and hope you had a good experience otherwise with LP360
that might lead to a future purchase.

As mentioned on the phone, you want to make sure the DLLs are unregistered.
To do this, run (double-click in Explorer) the file C:\Program Files\LP360\bin\unregall.bat
(I run a program called RegDllView to check what DLLs are registered, look for LASSymbols.dll, etc.)
Also, you should disable the extension in ArcMap.

Hope this helps,
Thanks,
Mike
