Thanks for the insights Joe. We're sort of in the same boat - our Response folks are in the middle of getting a NewWorld CAD system ironed out, which is taking a while. We've had to do some work-around addressing in a few spots to make it happy. Our budget is being drawn up now for the next financial year, so if NextGen 911 is in the works, we need to get in the budget soon if we want to have funding starting in July 2017. If we wait another few months, it will be a year and a half (July 2018) before it would get funded. And if NextGen 911 requires added personnel, that will be a budget battle in itself on top of it. As I'm discovering now that I'm the Public Sector, the cogs of government churn endlessly but slowly..... And as for your comment on address points, gotta have them. Centerlines are nice, but address points are the way to go. Chris Donohue, GISP

Not an immediate solution to your question, but related - the Remote Sensing world now has a variety of Feature Extraction processes developed to do much of what you want. However, while ArcGIS has some of the functionality, to my knowledge it is missing some of the pieces needed to make this happen without purchasing third-party add-on software (however, users of ArcGIS 10.3 and 10.4 can correct me if ESRI has added to the capabilities). For example, in a class in Remote Sensing I had we used Feature Extraction processes to automatically identify and extract helicopters in an aerial image full of aircraft on a tarmac. As another example, here's a feature extraction process that involves ArcMap and eCognition: Lesson 5: Feature Extraction | GEOG 883: Remote Sensing for Geospatial Intelligence Professional Chris Donohue, GISP

To answer your question, consider this - What are the requirements of the final project? Is it a cartography display of existing data? Analysis to derive new data? Both? Something else? The New York City Planning Department has some interesting topics and GIS data. Check out: Open Data Chris Donohue, GISP

Wait, found it. Check out the full list at this link: FAQ: What do the icons in ArcCatalog represent? ------------- (see above link for all the icons - this is just the first part) Chris Donohue, GISP

‎10-21-2016

I don't know if there is a single source for all the icons, but many of them are depicted and labeled in the several help sections for ArcCatalog. This will require a bit of reading and scrolling around, though. ArcGIS Help (10.2, 10.2.1, and 10.2.2) A quick tour of ArcCatalog ArcGIS Help (10.2, 10.2.1, and 10.2.2) Making connections in ArcCatalog ArcGIS Help (10.2, 10.2.1, and 10.2.2) The Catalog tree and item properties in ArcCatalog For the ones that are not depicted, one can try creating items in a test environment and see what icon appears. For example, try making a File Geodatabase and observe what icon ArcCatalog gives it. Then make a Feature Dataset within the File Geodatabase. Then Make a point Feature Class, etc. Chris Donohue, GISP

next gen 911‌addressing##911 addressing At the local GIS Users group meeting a few days ago there was a presentation on Next Generation 911, how it will differ from the current system, and that it is hoped to be implemented by the year 2020 in the United States and Canada. I do addressing for a medium-sized city, so am curious how this will roll down to my level, since I am not directly involved in response but the response folks do use the addresses I assign. Since NextGen 911 will be directly using municipalities centerline GIS data instead of phone company records, this caught my attention. So some beginner questions: Is the project on track for 2020 in all areas? Has anyone fully implemented NextGen 911 already? What level of effort does it typically require municipalities to update their centerline data so it works with surrounding municipalities in NextGen 911? What level of effort is anticipated once the centerline data is in use in NextGen 911 to do the ongoing maintenance? Is it expected to require extra staffing? Is it expected that address points will be a requirement in the near future (sounds like they are not required in the current implementation)? Have municipalities and call centers (PSAP) been able to get funding to help implement NextGen 911? Organizational funding? Grants? If you have worked on this, any insight on issues that have come up? Also, on the legislative side, is there a mandate that specifies when the system must be in place? Or is it voluntary at this point? Chris Donohue, GISP

Monty Python, in search of the holy code: "But you're VB! What are you doing in the Python Parser?" Chris Donohue, GISP

‎10-21-2016

"The label expression box doesn't use the normal !Field! notation, just to keep you on your toes." Good catch. The whole lack of !Field! notation despite being in the Python mode was making me wonder if my software was corrupted. Maybe we could submit this to ArcGIS Ideas to standardize this so folks won't be confused? Chris Donohue, GISP

That worked! Thanks Darren. Chris Donohue, GISP

I was noticing that too. It doesn't matter if the Parser in the Label Expression is changed to Python first or not, the field names come across with brackets when one double-clicks on the field you want to select it. On top of that, if one changes the field name to be surrounded by exclamation marks instead of brackets(with Python still selected as the Parser) it errors out: As for the one-space indentation, it is actually two spaces and that seems to be what ArcGIS defaults to.

If I purely use a number in the format, it works correctly. But now the catch, how do I substitute in SHAPE_Area so it labels based on that field that with comma separators instead of a hard-coded number? Chris Donohue, GISP

‎10-20-2016

How does one use Python to format a number label so it shows the thousands separator? For example, I have a value of 12345 that I want to display (from the Shape.Area field of a File Geodatabase feature class) on the map as a label as 12,345. I looked at these discussions, but can't seem to get it to work. What is label expression for formatting a number to have thousands separator and decimals? python - Add 'decimal-mark' thousands separators to a number - Stack Overflow I guess I could slice the value and insert commas, but I was hoping to use something easier. I'm using ArcGIS 10.2.1 (so Python 2.7.5). I'm a beginner in Python, so there is a good chance I am just missing something basic in trying to do this. Chris Donohue, GISP

I'd go with the suggestion by bixb0012 . Chris Donohue, GISP

There are several possibilities to help resolve those. First, can you define what the things are that need to be "standardized"? If so, there are ways to use code to help "clean up" the address entities into more standard formats. There are several folks on here who have in the past provided Python script that has greatly aided in address data cleanup. For example, to clean up street suffixes, Darren Wiens provided some nice Python advice on how to do this. Python - using Replace in Field Calculator Also, there are several folks on GeoNet who regularly have to clean up address data, so may have some ideas to share. jborgion Chris Donohue, GISP
