Grid Distance/Azimuth converted to Ground Distance/Azimuth

TylerT

Hello,

I have drawn a line in a specified state plane coordinate system map and feature class. Now I would like to label/report the ground distance and azimuth of this line. Is there a stock geoprocessing tool for calculating grid to ground distances and directions?

Thank you.

Tyler

try this:

I'm not seeing a ground distance parameter in that tool. Am I missing something? Thx. Tyler

DanLee

It seems you drew the line in state plane coordinate system; the Shape_Length of the line should be the ground distance. Otherwise, I am not sure what you meant by ground distance.

TylerT

The line is in Grid Distance (ie. State Plane Coordinates). I need to report back ground distance or what we would actually measure on the ground.

I could calculate it, but it's safer to use a tool that's been developed and QC'd. I'm just not seeing any tools at first glance.

I checked with our 3d team member. He said:

"The Add Surface Information tool has a Surface Length option. If the input geometry is already 3D the Add Z Information tool has a 3D Length option."

Thx. I'll look into these. Tyler
