ទិដ្ឋភាពទូទៅ

The tool works in both latitude/longitude and projected X/Y, and reports bearings as north azimuth, quadrant bearing, or both.

ការប្រើប្រាស់

The tool has two modes, selected with Calculate in table?:
- Unchecked (single pair) — Type the four coordinate values into X-Coordinate of Start Point through Y-Coordinate of End Point. The result is reported in the tool messages.
- Checked (batch) — Supply Input Table holding coordinate pairs and Specify output table to receive the calculated bearings and distances.
Coordinate Type must match the values supplied. Setting it to Projected X/Y while entering degrees, or the reverse, produces results that look plausible but are wrong by orders of magnitude.
- Latitude/Longitude — values in decimal degrees; distance is computed on the ellipsoid.
- Projected X/Y — values in projected units; distance is computed on the plane.
Distance Unit and Bearing Unit each offer a combined option that reports two forms side by side: Choose a combined option when the same result must be read by different audiences.
- Meters - Kilometers reports both metres and kilometres.
- NAz - Quadrant (DMS) reports both north azimuth and quadrant bearing.

Parameters for Direction Distance
ឈ្មោះ	ប្រភេទទិន្នន័យ	ការពិពណ៌នា
Calculate in table?ជម្រើស	Boolean	Selects batch mode. Checked — Input Table and Specify output table are used; the coordinate boxes are ignored. Unchecked (default) — The four coordinate boxes are used for a single calculation.
Coordinate Type	String	The kind of coordinates supplied. Must match the input values. `Latitude/Longitude` — decimal degrees `Projected X/Y` — projected units
X-Coordinate of Start Pointជម្រើស	Double	The X or longitude value of the start point. Single-pair mode only.
Y-Coordinate of Start Pointជម្រើស	Double	The Y or latitude value of the start point. Single-pair mode only.
X-Coordinate of End Pointជម្រើស	Double	The X or longitude value of the end point. Single-pair mode only.
Y-Coordinate of End Pointជម្រើស	Double	The Y or latitude value of the end point. Single-pair mode only.
Input Tableជម្រើស	Feature Layer; Table View	A table or feature layer holding the coordinate pairs to process. Required in batch mode.
Specify output tableជម្រើស	Table	The table that receives the calculated bearings and distances. Required in batch mode.
Distance Unit	String	The unit the distance is reported in. `Meters - Kilometers` — both `Meters` `Kilometers`
Bearing Unit	String	The form the bearing is reported in. `NAz - Quadrant (DMS)` — both `NAz` — north azimuth `Quadrant (DMS)` — quadrant bearing in degrees, minutes, seconds

របៀបប្រើ

Single pair

On the KGA Toolbox tab, in the Spatial Analysis group, open the Spatial Analysis menu and click Direction Distance.
Leave Calculate in table? unchecked.
Set Coordinate Type to match the coordinates you will enter.
Type the start and end coordinates into the four boxes.
Set Distance Unit and Bearing Unit.
Click Run and read the result in the tool messages.

Batch from a table

Open the tool and check Calculate in table?.
Set Coordinate Type.
Set Input Table to the table of coordinate pairs.
Set Specify output table.
Set Distance Unit and Bearing Unit, then click Run.
