Would love to have a more up to date copy of this

JTS Geometry Model (OGC 99-049)

● Spatial Predicates● Intersects, Contains, Within, Covers, etc

● Geometry Validation● Overlay Boolean operations

● Intersection, Union, Difference, SymDifference● Metrics

● Length, Area, Distance, Hausdorff Distance● Buffer

● Pos/Neg, Cap/Join styles● Polygonization● Delaunay Triangulation● Voronoi Diagram

JTS Functions

Geometry Example

GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory();

Coordinate coord = new Coordinate(1, 1);Point point = geometryFactory.createPoint(coord);

WKT Example

GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory();WKTReader reader = new WKTReader(geometryFactory);

Point point = (Point) reader.read("POINT (1 1)");

Buffer Example

GeometryFactory geometryFactory = JTSFactoryFinder.getGeometryFactory();WKTReader reader = new WKTReader( geometryFactory );

LineString line = (LineString) reader.read("LINESTRING(0 2, 2 0, 8 6)");Geometry buffer = line.buffer( 0.75 );

ProjectsMobile Map ToolsEclipse FoundationLocationTech

Mobile Map Tools• SDK For native mobile applications.• Supports:

• Mobile maps in 2D, 2.5D and 3D• Works on iOS, Android, webGL

• Built using C++ and translated to Java and JavaScript• License:

• Eclipse Distribution License 1.0 (BSD)

Capabilities

Vector tiles:● Raster● Vectorial● 3D models● offline maps● complex symbology● native

New: Vector Tiles● Postgis● GeoJSON pyramid● Native support on MMT

● Berkeley DB● Import and orderedpoint process● Point cloud streaming● Native support on MMT● The cloud save the shape(we are always sending meaningful points, that saves the shape of the point cloud)

New: Point Cloud Streaming

Spatial4j

Freelance Lucene/Solr developer/consultant

Spatial4j

Shapes!• Point, Rect, Circle, Line, BufferedLine, Polygon,

and collections of these• Cartesian, Cartesian with world-wrap

(cylindrical), and Spherical/Geodesic• Computes intersection relationship & bbox

Also• Computes point distance & shape area• Extensible WKT parsing and

serialization/deserialization utilitiesLicense: ASLv2

The Shape interface• interface Shape {

• Point getCenter();• Rectangle getBoundingBox();• boolean hasArea();• double getArea();• SpatialRelation relate(Shape other);

• Must support Point & Rectangle

• enum SpatialRelation• DISJOINT, INTERSECTS, WITHIN, CONTAINS• Note: simpler set than the “DE-9IM” spatial standard

• no “equals” or “touches”

Distance example

SpatialContext ctx = SpatialContext.GEO;

Circle sydney=ctx.makeCircle(151.3,33.9, 0.3);Point perth=ctx.makePoint(115.8,32.9);double distance=ctx.calcDistance(sydney.getCenter(), perth);

double km=DistanceUtils.degrees2Dist( distance, DistanceUtils.EARTH_MEAN_RADIUS_KM)

More code samplesSpatialContext ctx = SpatialContext.GEO;Rectangle r = ctx.makeRectangle(-71, -70, 42, 43);Circle c = ctx.makeCircle(-72, 42, 1);SpatialRelation rel = r.relate(c);System.out.println(rel);rel.intersects();//boolean

ctx = JtsSpatialContext.GEO;Shape s = ctx.readShape(“POLYGON ((30 10, 10 20, 20 40, 40 40, 30 10))”);

double distanceDegrees = ctx.getDistCalc().distance( ctx.makePoint(2, 2), ctx.makePoint(3, 3) );

Distances (including circle radius) are in “Degrees”, not

radians or KM

GeoTrellis● Functional programming with Scala

● To quote Anthony Fox of GeoMesa, “There’s a confluence of geo and spark happening at LocationTech”

● Big data, cluster computing with Apache Spark & Accumulo● Both GeoMesa and GeoTrellis use Accumulo. Spark is

becoming a very popular alternative to Hadoop.
