Create line features between point features within a given distance

PatrickGreber

Good morning everybody!

I'm currently working on a small GIS-Project regarding Network-Analysis. First I wanted to develop a network between certain wetland areas. I have created a point feature class in the centre of each wetland polygon. Now i try to connect these points with lines to create a network I can work with. Is there a tool that is able to connect each point feature with other point featues in a distance of 1300 Meters through a line?

In a next step I would like to adapt the distance regarding ecological and topographical information, through a cost-distance or multi-criteria analysis. Would this tool from step one be able to integrate such a cost-distance analysis and only connect point features within an adapted distance?

I'm really new to this with little expirience and grateful for any support !

Thank you in advance for your help 😃

Yes! That's an idea I was already working on. Could it be possible to add a cost that represents the distance? As an Example: Create a buffer around each point and cells within each cell have no cost an cells outside the buffer have high cost values? Than run the least cost ath analysis?

Thank you for your time, I really appreciate it!

The double-post is a forum blip. I was sure I replied initially, then it disappeared and I reposted.
You might want to check out the Cost-Distance toolset.

It would take a little work to create a cost raster initially, but then you can create cost-distance rasters from each habitat, also run least-cost path analysis from each habitat, then possibly append the results to the edges (connecting lines) of your network.

Yes, that would totally help! As a part of a school exercise, I need to do a network analaysis and calculate centrality measures of a network. But first I have to generate such a network by myself.

My idea was to create a network of wetland habitats that are connected through lines. A habitat is only connectet if in reach of the dispersal distance of a certain butterfly (1300m in my case). In the end, I hoped to get a network with connected habitats and that I'm able to calculate centralities of each area. Furthtermore, I wanted to affect the dispersal distance by other features like streets, woodlands or lakes (travelling through these habitats cost more). The task with the centrality is given by my school and needs to be implemented.

So my ultimate goal would be a network of wetlands that are connected with each oter dependent on dispersal distance and topographical barriers.

Does this help=)?

Thank you for your time and help!

You could generate a near table, get rid of any values over 1300 and then use the XY to line tool to generate the edges you need.

What's your end-goal with this?

DavidPike

It's a bit dated, but the technique should still be the same

generate a near table and then create the lines from that. (I guess you delete any table values over 1300 before you generate the lines)

As to the other questions, it might be better to state what you want to achieve rather than us helping you with a solution you've proposed.
