Is there any one that can help me?!

Just in case the assignment isn't due yet, I have posted another installment on my blog You are not allowed to use geoprocessing results the students get smarter Enjoy

Philip, I think Dan still did a lot for you, he could do it easiliy. But it's your work to learn it, if you want to reach his skills 🙂

By the way, I would be interested to hear about your instructors reasons why you should't use model builder?

Could you ask him?

Maybe he's here inside and could enlight me?

DanPatterson_Retired

Philip... because of demands I can't look at individual cases. The current session is the one that is open when you open arcmap

DanPatterson_Retired

Chris...more to come...you can tie in the arcpy.mapping module with this as well. Should be done over the weekend at the latest since I will be using this amongst my examples for a class next week...

PhilipKegels

Dan, thanks a lot!!!!

Please, can you sent me an email: philipkegels@hotmail.com -> If you want, i sent you my data. Maybe you can watch at it?

When I open a blank map --> there is no current session.

Thx!!!

Dan:

This is a nice summary in your blog. I didn't know about the Python Code Snippet function - that will be handy. Thanks for posting that.

I have produced a demo workaround to the use of modelbuilder on my blog. This is part 1. Part 2 of the blog will be completed over the weekend ... hope this gives you some idea.

The pdf document there will give you the generic workflow for a particular task. Your task would be to emulate it with your requirements.

The next instalment will show how to incorporate arcpy's mapping module within a workflow as either a substitute or an enhancement to general ArcToolbox tools

Since when students make what teachers say? Never heared that 🙂

What faculty forbid the use of model builder? And if it's like that, you can use it nevertheless ... if you have finished, it's easy to change the cody so that it doesn't looks model builder alike.

That's what I would do ...

PhilipKegels

THanks a lot! The thing is that using modelbuilder is forbidden So i have to do iT only with python. Using ArcMap is not That difficult bUT to write a script that do the same thing is not That easy i think. Keep you posting. I hope tomorrow i will be a step further.

PhilipKegels

Thanks a lot! I Will try it tomorrow! keep you posting!

Here is a quick example...

Step 1, select the Results in Geoprocessing option
2...select the day that you did something that worked (or failed)
3 select the Arctoolbox tool used
4 copy to a python snippet to give you the bare bones python syntax to build a standalone script or to verify Modelbuilder script output

ie below is the output below for two processes...but it isn't ready to run standalone...that is the next lesson...


# Replace a layer/table view name with a path to a dataset (which can be a layer file) or create the layer/table view within the script
# The following inputs are layers or table views: "AOI_demo"
arcpy.RepairGeometry_management(in_features="AOI_demo",delete_null="DELETE_NULL")


# Replace a layer/table view name with a path to a dataset (which can be a layer file) or create the layer/table view within the script
# The following inputs are layers or table views: "AOI_mtm9"
arcpy.DefineProjection_management(in_dataset="AOI_mtm9",coor_system="PRO .......

To add to Chris's suggestion...If you go to the Results window in the Geoprocessing section...the workflow that you used for tools in ArcToolbox will be saved, whether they were successful or not. you can reconstruct your workflow by exporting python snippets. These can be used to generate a script directly by filling in the blanks...it can be used to verify the output from Modelbuilderbuilder to Python and other purposes. Good luck

Ooof. Sounds like you are a grad student.

Unfortunately, using Python in ArcGIS is not something that is learned immediately, so if you haven't had an opportunity to study it before, hopefully you have some time before this project is due.

One potential solution - if you know Modelbuilder at all, you can create your analysis process there, then export the whole thing as a Python Script. Given that your analysis criteria don't appear to be too complex, this could work out well. For the most part you would not have to learn Python, as Modelbuilder will create the code for you.

Modelbuilder (in general):

I've been working eight days on it for research. My teacher has just placed an order and we had to look up everything on ourselfs.

PhilipKegels

I don't know how to begin on it. I already did it in ArcMap. I have already over the 10 lots (picture).

Now, i have to write a script that i can use for ArcMap and just put different conditions.

DanPatterson_Retired

Homework is helped when the "what I have tried" is provided...or when the due date has passed.

Zeke

Maybe show what you've got so far, then get help for that.
