ArcPad: Buffer line

IngridHogle — Tue, 24 May 2016 23:29:19 GMT

Is there a way (has anyone written a script?) to create a new polygon by buffering both sides of a line in ArcPad? (An out-of-the-box Buffer Method is available for a Point Object, but not for a Line Object.)

Is it for visual effect or are you trying to capture the buffer and do some calculations? If just visual, maybe duplicate/offset the line the distance on either side of the line?

I've done things like snap a couple points near a coastline and then clip the section out, and save to a shapefile....but don't think I've done anything with polygons. But I'm still customizing for 7.x.

Yes, it is for visualization, and I could just create two lines as you suggest. It seems like it should be possible to offset two lines (one on either side of the original) and then connect the start points and end points to create a polygon though, which would be really nice. I am hoping someone else has done the scripting to make this happen and would be willing to share this, since I am not a developer.

Is this data that exists or something that you are collecting? Is is via GPS or one screen? What version are you using?

I don't know of any script that does this out of the box, but maybe you are needing to look into the Offset feature. If I was going to try to do this, I would start by looking at some of these reasources I found (help is for 8.0, there may be better, depending on your version)

ArcPad User Guide

http://resourcesupplyllc.com/PDFs/ArcPadGPS_Offsets_RSLLC.pdf this looks interesting, although I have not read thru it all

Offset Method ...this would take some developer skills

Can you give a little more info on what you are trying to achieve and the input format?
