Create a Prediction Path Model with ArcGIS

[darksabersan]

Hi guys,

 

I have a simple idea, but I didn't found how to make it possible.

I would like to create a special model in order to have a kind of prediction path between points.

The general idea is to start from point A to reach point B, but taking in account the terrain (Slope) without any vector line.

What I have already done with ArcGIS..

And this is the result of the slope..

Now, I would like to realize a kind of spider network like that..

Is there any possibility to create a spider network from points within a certain distance in order to don't connect data that are far away from each other?

 

Any suggestions and ideas are really welcome.

What do you want to achieve by this? a little explanation about your purpose would help us understand your problem

[darksabersan]

OK,

I would like to create a model for making decision.

Starting from point A to reach point B. The green points represent angle less then 45%.

The idea is to have a spider network, like represented in my first post in order to create a route model.

There is a way to perform such analysis, but it is in qgis

 

http://www.qgistutorials.com/en/docs/nearest_neighbor_analysis.html

 

Basic arcpy algorithm may be(assuming your points area uniformly distributed)-

 

1. Define "main feature"(point layer)

 

2. Run point distance tool("main feature" against "main feature") and give search radius (this case highest is diagonal of nearest point pair) >table (TBL)

 

3. Select INPUT_ID & OUTPUT_ID pairs (by looping array etc on this TBL)

 

4. Get XY from "main feature" for these pairs startX,startY,EndX,EndY

 

5. Create Polyline

Thank you msig0000 for your reply, but I will need it in my model on ArcGIS.

Dear,

 

I have made a script tool that generates the spider network(as you needed)- see shot attached

 

Usage: just locate the tool script in arc catalog. It needs four parameters

 

1. Input point feature

2.Output folder/work space

3.Output shapefile name

4.Search radius (for your case get the diagonal distance between two neighbor points using measure tool)

I'm going to do some test.

 

Thanks men.

msig0000,

 

I have an issue with the tool:

Hi Dear Thanks for ur try,

 

Care this tool is only tested against shapefile(input and output) and folder(as workspace-not gdb etc).

Have u chacked the name of ur point shapefile(or name of output shapefile, folder etc. ) u r tring to connect (e.g name is "offset-line.shp") where hyphen is not allowed.

 

So far i see u have invalid word in the path i.e. \ESRI-master  in File "C:\Prediction_Path_Model\MODEL\ESRI-master\Toolbox.tbx#ConnectPoints.py

where hyphen is not allowed it will be \ESRI_master or others which is valid

 

USE THE UPDATED SCRIPT FROM GITHUB (Added) NOW.
