When exporting a MultiLineString to GeoJSON, I expected MultiLineString, but got LineString.

        String wkt = "multilinestring((1 1,2 2,3 3),(7 7,8 8,9 9))";
        OGCGeometry og0 = OGCGeometry.fromText(wkt);
        og0.setSpatialReference(null);
        System.out.println(og0.asText());  // MultiLineString, as expected
        String outJson = og0.asGeoJson();
        System.out.println(outJson);  // expect MultiLineString, got LineString
        OGCGeometry og1 = OGCGeometry.fromGeoJson(outJson);
        System.out.println(og1.asText());  // expect MultiLineString, got LineString

This impacts ST_AsGeoJSON in spatial-framework-for-hadoop: Esri/spatial-framework-for-hadoop#10 .

Hi,
I am trying to use Operator Intersects but GeometryEngine does not have an intersects that returns boolean.
There is a intersect (returns Geometry) but no intersects.
Is it a new addition that will only be available for the new release.(But documented early.)

Thanks
Manas

Hi,
I am trying to use ESRI api to create Line from two points using scala.
If I try the following line
val line = new Line() // same as trying "Line line = new Line() in java"
I get a stack trace on my scala interpreter.

I am using esri geometry api version = 1.2
When I create point or polygon I don't get any crash. Only when I try Line I get this stack trace.
The problem can't be as big as the constructor is bad; I think I am doing something wrong just can't figure out what?

The stack trace that I get is copied below:

Listening cursor is needed to support push pattern in geometry cursor for aggregate union and convex hull

According with the description in the below link:
http://edndoc.esri.com/arcobjects/9.2/JAVA/584733d2-3a53-11dc-a403-4faa7246d1c1.htm#About

If the input polylines cross with each other, base on the description, the result should return four lines which separate by the intersection point. But the actual result is same as the input polylines.

For the summary, the execution result for the simplify API does not consistent with its description.

Given two polygons that intersect to a polyline and dimension mask = 2, the returned polyline should not be empty.

Input geometry:
{"rings":[[[-97.174860352323378,48.717174479818425],[-97.020624513410553,58.210155436624177],[-94.087641114245969,58.210155436624177],[-94.087641114245969,48.639781902013226],[-97.174860352323378,48.717174479818425]]]}

Intersector:
{"rings":[[[-94.08764111399995,52.68342763000004],[-94.08764111399995,56.835188018000053],[-90.285921520999977,62.345706350000057],[-94.08764111399995,52.68342763000004]]]}

Dimension mask = 2
Wkid = 4326

To reproduce, run OperatorExportToGeoJson.local().execute with exportFlags = GeoJsonExportFlags.geoJsonExportDefaults, spatial reference wkid = 3857, and the following geometry:

{"rings":[[[1600,9082],[1600,8682],[1100,8682],[1100,9082],[1600,9082]]]}

The output looks like this:
{"type":"Polygon","coordinates":[[[1600.0,9082.0],[1600.0,8682.0],[1100.0,8682.0],[1100.0,9082.0],[1600.0,9082.0]]]}

It really would be better to have the spatial reference in the output especially since it is an input parameter.

Input polyline:
{"paths":[[[2,0],[4,3],[5,1],[3.25,1.875],[1,3]]],"spatialReference":{"wkid":4326}}

Output polyline:
{"paths":[[[2,0],[3.25,1.875]],[[3.25,1.875],[4,3],[5,1],[3.25,1.875]],[[3.25,1.875],[1,3]]],"spatialReference":{"wkid":4326}}

The output polyline has a closed ring and two more paths. Each path is in a different color.

Recall that the boundary of a closed ring is empty. The output polyline is not OGC simple because it violates the following condition:
"A MultiCurve is simple if and only if all of its elements are simple and the only intersections between any two elements occur at Points that are on the boundaries of both elements."

The output polyline should be:
{"paths":[[[2,0],[3.25,1.875]],[[3.25,1.875],[4,3],[5,1]],[[5,1],[3.25,1.875]],[[3.25,1.875],[1,3]]],"spatialReference":{"wkid":4326}}

OperatorContains returns true, but it should be false.

JSON strings
{"rings":[[[0,0],[0,10],[10,10],[10,0]],[[12,8],[12,10],[18,10],[18,8],[12,8]]]}
{"paths":[[[2,2],[2,8],[8,8],[8,2]],[[12,2],[12,4],[18,4],[18,2]]]}

Expose JsonCursor publicly and convert it to an interface rather than an abstract class

The cases in question are

1. the cuttee and the cutter don't intersect at all
2. the cuttee is a polygon and cutter doesn't pass all the way through it
3. the cuttee is a polyline, the cutter touches the cuttee but b_consider_touch is false.

Currently, a pointer to a geometry cursor is returned. There are two empty geometries in the cursor, one for the left cut and one for the right cut. It would be a more obvious signal to the user that there were no valid cuts if a null pointer was returned instead.

Here are some simple cases to reproduce the issues listed above.

cutter1: {"paths":[[[1.5,0.5],[2.5,0.5]]]}

cutter2: {"paths":[[[0.5,0.5],[1.5,0.5]]]}

cutter3: {"paths":[[[0.2,0.4],[0.6,0.8]]]}

polygon (cuttee): {"rings":[[[0,0],[0,1],[1,1],[1,0],[0,0]]]}

polyline (cuttee): {"paths":[[[0.0,0.6],[0.4,0.2],[0.5,0.5]]]}

Currently, OperatorImportFromGeoJSON only accepts spatial references in this form:

"crs":"EPSG:4326"

The operator should at least also accept this form:

"crs":{"type":"name","properties":{"name":"EPSG:4326"}

Need OperatorImportFromJson.local().execute() function that takes a String parameter. Currently,OperatorImportFromJson.local().execute() function requires that a String be wrapped in a JsonParser object and it throws an IllegalArgumentException.

The OperatorSimplifyOGC does not work normally when one polyline cross itself.
For example: one polyline ACDEF cross at point B, In the older version of OperatorSimplifyOGC instance, it returns three geometries:
1. AB
2. BF
3. BCDEB

But the latest version, the result like below

1. AB
2. BF
3. BCD
4. DEB

Is it a issue or a behavior change for OperatorSimplifyOGC ?

Make PointXD and EvenlopeXD implement serializable

Envelope2D.getLowerLeft, getUpperLeft, and similar should return Point2D. Corresponding methods in the Envelope class should return Point.

when shapefile projection is wkt not wk. I make json used Featrues to json。SpatialReference of ESRIFeatureClass is null. and the api not realize ProjectionTransformation function.

expose execute method that takes geometry cursor public for developer efficiency as the other methods are creating a "local" cursor

Hi,
This is more of a usability question than an issue. I could not find a documentation as to how to use QuadTree.
My tree creation function looks something like below -

def getQTree(grid : Array[(Int, Geometry)]) = {
val quadTree = new QuadTree(new Envelope2D(-180, -90, 180, 90), 8)
val g = grid.zipWithIndex.map(kv => (kv._2, kv._1._2))
var hint = -1
grid.foreach { kv=>
var env = new Envelope2D
kv._2.queryEnvelope2D(env)
hint = quadTree.insert(kv._1, env, hint)
}
quadTree
}

In my above function grid is a quarter degree cells for the world for which I want to create an index.
Now that the tree is created how do I get back the list of elements for a given geometry?
Also how does the tolerance work in the functions "quadTree.getIterator(query, someTolerance)"

I could not find any documentation for the QuadTree except the mention of class name in the wiki.

Thanks
Manas

In such that it can be accessed in the case of Envelope2D.queryLowerLeft function

Same with setXY(int index, Point2D pt);

Proximity2DResult does not have methods to set/get boolean signifying right side.
We need these two methods:

1. setRightSide()
2. isRightSide()

Then we need to implement this method which calculates left/right side:

public abstract Proximity2DResult getNearestCoordinate(Geometry geom, Point inputPoint, boolean bTestPolygonInterior, boolean bCalculateLeftRightSide);

Currently new builds are not being kicked off when checkins are made to this repository. Someone that manages this repo must login with github at http://travis-ci.org. Go to the accounts drop down under the username on the right, synchronize with github by pressing the "Sync Now" button, then toggle the geometry-api-java repository. The next time a checkin is made the build process will begin and the status image will be updated.

I'd like to use Envelope3D in some code built on geometry-api. Thanks.

GeometryEngine.geometryToJson function returns JSON with comma as decimal separator. In JSON it should be always dot. Sample testcase:

import java.util.Locale;

import org.junit.Test;
import org.testng.Assert;

import com.esri.core.geometry.GeometryEngine;
import com.esri.core.geometry.Point;

public class GeometryEngineTest {

    @Test
    public void testConvertFromJson() {
        Point p = new Point(494930d, 6086557d);
        // in LT default decimal separator is comma (",")
        Locale.setDefault(new Locale("lt"));
        String json = GeometryEngine.geometryToJson(3346, p);
        // got: {"x":494930,00000000000,"y":6086557,0000000000, ...
        // expected: {"x":494930.00000000000,"y":6086557.0000000000, ...
        Assert.assertFalse(json.matches(".*\\d,\\d.*"), "Expected that JSON contains dot (.) as decimal separator");
    }
}

Investigate and remove FIXME comments.

There are 72 FIXME comments in 24 files.

For example,
// FIXME check to see if boolean for inversion should be changed

If we have a polygon with one ring that looks like a bow tie, OperatorSimplifyOGC should break it up into two rings.

Input polygon:
{"rings":[[[0, 0], [0, 10], [5, 5], [10, 10], [10, 0], [5, 5], [0, 0]]],"spatialReference":{"wkid":4326}}

Output from OperatorSimplifyOGC:
{"rings":[[[0,0],[0,10],[5,5],[10,10],[10,0],[5,5],[0,0]]],"spatialReference":{"wkid":4326}}

Output should be:
{"rings":[[[0,0],[0,10],[5,5],[0,0]],[[10,0],[5,5],[10,10],[10,0]]],"spatialReference":{"wkid":4326}}

OperatorIntersection throws ArrayIndexOutOfBoundsException when using a dimension mask and the intersection of two polygons is empty.

java.lang.ArrayIndexOutOfBoundsException: 4

Geometry dst_geom = tryNativeImplementation_(input_geom);

but the dimension of dst_geom is 2.

Given below is a code snippet that can be used to reproduce the problem.

Polygon poly1 = new Polygon();
poly1.startPath(0,0);
poly1.lineTo(0,10);
poly1.lineTo(10,10);
poly1.lineTo(10,0);

Polygon poly2 = new Polygon();
poly2.startPath(10.5,4);
poly2.lineTo(10.5,8);
poly2.lineTo(14,10);

try {
  OperatorIntersection op = (OperatorIntersection) factory.getOperator(Operator.Type.Intersection);
  GeometryCursor result_cursor = op.execute(new SimpleGeometryCursor(poly1), new SimpleGeometryCursor(poly2), SpatialReference.create(4326), null, 1);
  Geometry geom = null;
  while((geom = result_cursor.next()) != null) {
    System.out.println(geom.getType());
  }
}
catch (Exception e) {   
  e.printStackTrace();
  System.exit(-1);
}

Clarify the behavior for geometry types.

The method javadoc implies that intersect does exactly what isIntersecting does, when it actually changes the instance to be the intersection.

class Envelope2D {

   ...

  /**
   * Checks if this envelope intersects the other.
   * @return True if this envelope intersects the other.
  */
  public boolean intersect(Envelope2D other) {
  ...
  }

  ...

}

In order to build the package, Apache Ant is required. This should be included in the README.md under the 'Requirements' section.

When I use the ListeningGeometryCursor with OperatorUnion using the commited version of the code, I get the error:
The method tock() from the type GeometryCursor is not visible .
Cause: tock is declared protected in GeometryCursor.

This is used in ST_Aggr_Union: https://github.com/Esri/spatial-framework-for-hadoop/blob/38c334709b78dd3c774b12bdaeee3637f14b0503/hive/src/com/esri/hadoop/hive/ST_Aggr_Union.java

If instead of GeometryCursor, I try to declare the executing cursor as type OperatorUnionCursor, that is also an error, because class OperatorUnionCursor is not declared public -
The type com.esri.core.geometry.OperatorUnionCursor is not visible.

In OGCPolygon.java, ExteriorRing is named ExterorRing

OperatorBoundary throws an IllegalArgumentException if the input geometry is a polygon.

In Boundary.java, line6:

if (gt == Geometry.GeometryType.Polygon) {
Polyline dst = new Polyline(geom.getDescription());
if (!geom.isEmpty())
geom.copyTo(dst);

But dst is a polyline, geom is a polygon.

If a user tries to call OperatorSimpleRelation.accelerateGeometry(), a compile error is shown.

GeometryAccelerationDegree is not public in Geometry; cannot be accessed from outside package.

OperatorClip throws ArrayIndexOutOfBoundsException for a specific non-simple polygon.
