Hi all,
finally I came to study how to develop tools. I started from a Kosmo small tool
which I adopted to OJ. It basically calculate the angle between a segment and
the North, in a plane (UTM), in both degrees and radians.
that is the code:
************************************************
public MeasureAzimutUTMTool() {
super(2);
allowSnapping();}
protected void gestureFinished() throws Exception { Iterator it =
getCoordinates().iterator();
Coordinate c1=null,c2=null;
/**
* Calculates Degrees and Radians
*/
double d = 0;
if (it.hasNext())
c1 = (Coordinate)it.next();
if (it.hasNext())
c2 = (Coordinate)it.next();
LineSegment ls = new LineSegment(c1,c2);
d = ls.angle();
double DEG = 90 - d * (180/Math.PI);
double DEG1 = DEG;
if (DEG < 0)
DEG1 = DEG1 + 360;
double RAD = DEG1/180;
getPanel().getContext().setStatusMessage(
I18N.get("org.saig.jump.tools.messuring.MessureAzimutUTMTool.Angle-referencing-north")
+ ": " + getPanel().format(DEG1)+"° = " + getPanel().format(RAD) +
"\u03C0");
***********************************************
My idea is to start from this tool to obtain other surveying tools.
My questions are:
1) actually the tool only displays on status panel the value of the angle. I
need that it creates a new layer and , for every measuring, a point with the
values of degrees saved in an attribute
2) I need that the tools creates, for every measuring, a line with vectors
(segments) oriented according the calculated angles.
I really thatnk if someone can help me.
regards
Giuseppe
