Automatically creating measures/events or points along a polylineM

JasonScriffignano — Sun, 26 Sep 2010 21:38:04 GMT

Does anyone know how to automatically generate measures/events at a particular interval along an existing polylineM feature in ArcPad. I want to be able to press a button and it generates points or measures/events at a user given distance along a selected polylineM feature. The user can then go to those measures/events or points on the ground to conduct sampling and enter data into each point or measure/event.
Is this possible in ArcPad 8 or 10?

Sure, it's possible, but it would be a lot of work. The ArcPad object model gives you access to all the information you would need to do it, but I don't really see any helpful functions that would automate the geoprocessing (setting measures, etc) part of it. (Although the Point object does have a "measure" property, so maybe I'm just not seeing it.)

I'd start by checking out the "Line Object" help item in the Customizing ArcPad help, you can follow it down to "Parts" then "Item" within "Parts" then "Point" objects whose measures you can set and whose geographic location you have access to.

You'd basically have to break it down into its component parts and then rebuild it to the specified length, interpolating between existing vertices along the line, and then drop a point there.

Possible, but I wouldn't envy your task. 🙂

Hope this helps,
Eric
