Well, I believe current Excel and Libre Office Calc can only handle 1,000,000 records. So, they just can't read it. dbf and txt are the next choice from my experience. Good topic, thanks.

Thanks Dan. Joshua asked what it was exactly I was doing. I was attempting to use the Script in ArcView 3, having nothing to do with Python. Sorry for any confusion. But I'm thinking after this conversation I should just forget Avenue for now and get caught up.

Pups! 'them is fightin words' (sic) OK, I'll stick to it but in my spare time. But Joshua probably said something I needed to hear. (Python) So, looks like you guys like GIS and it goes way beyond The Job (judging by time stamps) Later

Point well taken. I'll stop procrastinating and attempt Python again. You asked "what error or unexpected results are you getting?" I should have been able to answer that. So, today I started from scratch, oddly enough I was stumped at an even earlier part in the script. Don't remember how I got further:( The lines were aView = av.GetProject.FindDoc('View1') 'Unrecognized object: aNetworkTheme aNetworkTheme = aView.FindTheme("nonetworkroads.shp") aNetworkThemeFTab = aNetworkTheme.GetFTab To me this looks like a new thing is created, aNetworkTheme from the nonetworkroads and builds a table for it. I'm guessing that when you run compile The marvelous ArcView 3 and Network Analyst put the cursor in the script where you need to address something. So, you think I should give this up and move on?

Hi Dan, Python 3 it is. I'm doing https://www.py4e.com/lessons if that doesn't cut it I'll go to Coursera and take that route. I have ArcView 10 with no maintenance. Pro might be available to me through a school I'm helping implement ESRI's ConnectED though ... But I can't justify the cost of coming up to date personally. A few years back I wanted to put my ArcView 3 on my Windows 7, you chimed in; you asked if it were legit, license wise. It was. But, I'm coming clean on this one. I'm really just playing with Network Analyst in ArcView 3, the extension NA came off a cd I had my hands on years ago. My professional use of GIS has fallen off, but I can't stay away from it. So, my hard place between the rocks is that sometimes I would qualify for the $100 version but occasionally qualify for ... the math says about $6500. But, with GeoWizard I can build polygons .. so i'm happy. So, with this post I will expect officers at the door. But I might be able to plea bargain. I was offered ArcInfo full license once, "Cracked"; didn't do it. "Easy transition,"? you have me laughing now.

Thank you Joshua. Glad its OK to ask an archaic question. I've bookmarked Dan's suggestions. I am trying to run the script in ArcView 3 with Network Analyst. All I got is: http://www.husdal.com/arc/2008/06/25/08-network-index/ It's the only tutorial/Information I could find. Can't justify purchase for my ArcGIS 10, so I'm basically playing. In my .apr I got about 20 scripts! Each compile got me one step further. Many errors were brought to my attention with cursor placement after trying to compile. The quote marks, empty spaces, and notation for comments in the script etc. etc. Fixed those and started running into others, I knew enough ... well actually I don't know enough to determine the problem. And after creating 20+ scripts I'm afraid I'm unable to answer your question. So, I'm going to start from scratch again, really read the script, actually take notes. Perhaps I can glean some Avenue from the script, prior to replacing my Avenue book. Best regards

Thank you Dan. Yes pet project. And I'm working with the script in Arcview 3 with Network Analyst. But I bookmarked your links, thanks for those, I have just signed up for a MOOC class for Python. I have attitude,, but aptitude is an issue for me. Have been putting off Python for years, on again and off again attempts at programming. But have never taken a class, that I hope will be the kicker for me.

This is going back, but it's where I'm from. (a forever young 62 year old who just loves GIS and sometimes fall back to ArcView 3). -Pays off sometimes:) I've been trying to run a script, my Avenue Book is nowhere to be found, and I'm a newbie. this is what I'm working with: Copy and Paste this script to the script window in ArcView (Use CTRL+V to paste): ‘ This script copies over node numbers from nodes.dbf and adds record ‘ numbers to the line theme feature table. It adds fields called RECORD#, ‘ FJUNCTION, and TJUNCTION to the line theme feature table. A network ‘ index directory must exist for the network theme before running this ‘ script. ‘ Get the view and the network theme. Substitute aViewName for the name ‘ of your view, and aThemeName for the name of your network theme. ‘ aView = av.GetProject.FindDoc(“VIEW_NAME_HERE”) aNetworkTheme = aView.FindTheme(“THEME_NAME_HERE”) aNetworkThemeFTab = aNetworkTheme.GetFTab ‘ Get the nodes.dbf file, make the VTab object, and get its fields ‘ aNetworkIndexDir = aNetworkTheme.AsString.Substitute(“shp”,”nws”) aNodeFile = FN.Merge(aNetworkIndexDir, “nodes.dbf”) aNodeVTab = VTab.Make(aNodeFile, false, false) aFjunction = aNodeVTab.FindField(“Fjunction”) aTjunction = aNodeVTab.FindField(“Tjunction”) ‘ Add Record#, Fjunction, Tjunction fields to network theme FTab ‘ aRecordField = Field.Make(“Record#”,#FIELD_LONG,12,0) aFjunctionField = Field.Make(“Fjunction”,#FIELD_LONG,12,0) aTjunctionField = Field.Make(“Tjunction”,#FIELD_LONG,12,0) aFieldList = {aRecordField,aFjunctionField,aTjunctionField} aNetworkThemeFTab.SetEditable(True) aNetworkThemeFTab.AddFields(aFieldList) ‘ Use nodes.dbf to populate Rec#, Fjunction, Tjunction ‘ Count = 0 for each r in aNetworkThemeFTab aFromNodeNumber = aNodeVTab.ReturnValueNumber(aFjunction,Count) aToNodeNumber = aNodeVTab.ReturnValueNumber(aTjunction,Count) aNetworkThemeFTab.SetValueNumber(aFjunctionField,r,aFromNodeNumber) aNetworkThemeFTab.SetValueNumber(aTjunctionField,r,aToNodeNumber) Count = Count + 1 aNetworkThemeFTab.SetValueNumber(aRecordField,r,Count) end aNetworkThemeFTab.SetEditable(False) Replace aView = av.GetProject.FindDoc(“aViewName”) with aView = av.GetProject.FindDoc(“View1”) or the name that you have given the view. Replace aNetworkTheme = aView.FindTheme(“aThemeName”) with aNetworkTheme = aView.FindTheme(“nonetwork”) or the name that you have given the theme. Click Script > Compile; then Script > Run I have identified (I think) and corrected (I think) what needs to be fixed. e.g. comment lines, quotation marks, names, etc. Just thought I'd ask. Hope this is appropriate for today and GeoNet.

was this resolved? pretty old But GIS is the perfect tool for this. ESRI recognizes maritime use of GIS > S-57

love this. Thank you, at 62 humor is refreshing. I am returning to the fetal position and probably the mind of a 5 year old. I have to say georeferencing is one of my favorite things to do; it can be a challenging (to get it right for the job at hand). Thanks

Maria Mapping Project Important lessons I felt this project was a marvelous opportunity and a generous offer, thank you ESRI. I remember reading early on that if a data point had enough similar observations it would be deemed reliable. To me, 67,632 records in a point database seem quite small in quantity, but working with 457 opinions, overwhelming. If there was a thread somewhere for users to communicate, I over looked it. I wonder if we could have had better results, without having been too costly in human resources, if we as a group had better communication. The important thing: ESRI’s goal was spot on (In a humanitarian and educational sense), and their software well suited. I was only able to get on board (AGOL) through a temporary involvement helping a GIS class, so opening it up to those outside of an AGOL Organization would be my request; Open to the public. I sometimes had problems with imagery redrawing in the post hurricane side, my ‘work around’ was just use the imagery showing damage when experiencing problems. Having assigned areas would have been my preference for an organized approach. A way of tracking my panning and location would have been awesome. I georeferenced screenshots form my points in ArcMap. I learned how tough it is to make a call (aspatial) and I should have used the text input box more. I should have pressed harder to get some students involved. Thank you Charlie, Crowdsource, and ESRI. See you next time,
