puntselectie op basis van buffer

T_Zett

<\/HEAD>

Hallo iedereen,<\/P>

<\/P>

Ik wil specifieke punten uit mijn dataset selecteren op basis van hun nabijheid tot elkaar. Hiervoor wil ik een buffer creëren rond alle punten en vervolgens alleen die selecteren die overlappen met ten minste 3 andere bufferzones (om gebieden met een hoge puntdichtheid te selecteren).<\/P>

<\/P>

Is er een manier om dit binnen ArcGIS te doen? Alle hulp wordt gewaardeerd.<\/P>

<\/P>

Alvast bedankt!!<\/P><\/BODY><\/HTML>

Hello David,

thank you for your help, unfortunately I don't have pro, I'm currently

working with 10.7. I have been looking for a way to do the count spatial

joints for this version, but have found nothing so far.

Thank you for any help in advance,

Theresa

There's better workflows, but for a beginner to GIS I might advise:

1. Create buffers from all your points - e.g. buffer all points by 100m

2.Run the Count Overlapping Features (Analysis)—ArcGIS Pro | Documentation tool. (if you don't have pro this may be a bit harder and need some spatial joins etc. let me know if this is the case)

3. use the 'select by location' tool (having selected only those buffer features with an overlap count >= 3) to find the original points within those areas.
