See http://docs.geotools.org/latest/tutorials/ for workbooks associated with this presentation. Are you new to GeoSpatial? Does scientific mumbo-jumbo make your head hurt? Are you (gasp!) just out to get the job done? Come to this work shop and go home happy. This GeoTools session is back by popular demand in a new long format workshop. Offering a visual introduction for Java developers we will exploring how you can integrate GIS services into your next project. For those new to the GeoSpatial scene we provide an introduction to current concepts and projects, and how to avoid common pitfalls. We start off with something nice, fun and visual - displaying local files using the development environment of your choice. Covering both the concepts and the science of map making the workbooks serve as an excellent reference, but the focus is always on you and the code you need to get the job done. We explore the concept of a Feature (literally something you can draw on a map), Geometry (what to actually draw) and details like coordinate reference systems, units and projections. The good news is all this stuff is captured at the Java level as nice normal objects by the GeoTools and Java Topology Suite projects. There are utility classes around so we can avoid going down into crazy scientific detail. The workshop offers a steady series of workbooks introducing: Feature creation Geometry, Coordinate Reference Systems and Re-projection Spatial Queries Handling large format rasters Working with Style We will work with a couple of common GeoSpatial data formats, the use of PostGIS, Web Map Servers (such as GeoServer and MapServer) and Web Feature Servers. Attend this workshop and be well-versed for the Java presentations at this years conference. Attend this workshop and receive one million randomly generated points free of charge. Just show up - it will be fun.

1. GeoSpatial for Java Introduction to GIS for the Java Developer

3. We will make use of number of Java projects

4. However the focus is on the ideas (we just happen to be using running code)

7. GeoTools since 2003

8. Spent the first 2 months being unable to compile

9. Decided to contribute to documentation

11. Founded 1994

12. Integration

14. Services

15. Support

17. GeoTools since 2005

18. Spends his time pruning complicated api

20. OpenGeo Stack

21. Responsible for the majority of GeoTools development at present

23. Cave Art or map to the best hunting ground?

24. A common theme is representation of walking time rather than distance. Allows map to be used as a planning tool.

27. Cholera victims all used the same water source

29. Started in Leads University

30. OSGeo Project in 2006

32. Anyone can Play

35. Easier to follow standards than having to invent names

37. Get it Done

41. Do you use maven for your project?

43. The machines have the software we are using today already downloaded

44. There is a DVD being passed around; copy the “GeospatialForJava” folder

45. If you succeed raise your hand and you will get a “Quickstart” workbook! + + ICON_Person_Q308 ICON_Person_Q308 ICON_CD-DVD_Q308

47. You have about 30 mins ICON_Person_Q308 NetBeans Quickstart Eclipse Quickstart Jars Maven M2Eclipse Jars Maven

48. Feature

50. When drawing a person you will often draw the features of a persons face (nose, ears, eyes, mouth)

52. We also record where the object is

55. This is a “dynamic type system” GeoSpatial Java Feature Object Attribute Field Operation method FeatureType Class properties {

59. GeoTools implements the Objects

61. Great example of building features by hand

63. Geometry and CRS

66. Numerically stable

67. This is the rocket science of GIS

69. http://tsusiatsoftware.net/jts/main.html

71. A single coordinate of two to four dimensions x=151.211111 y=-33.859972

72. GeometryFactory and WKT

75. LineString is a string of straight line segments

83. The units of distance are important

84. We really need the meaning of a shape

86. Latitude / Longitude

88. Distances measured in meters

91. We treat the numbers as measurements against a model of the earth

93. Geoid – gravity field – kind of like sea level

94. Where to measure from Easy on a flat surface Not as straight forward on a sphere Start with a point of origin Latitude – degrees north or south of the Equator Longitude – degrees east or west of the Prime Meridian

96. However Computer GIS systems often expect x/y order

98. You need to check the data

100. Line

103. Curve

107. And what it means

108. Filter

110. Think of it as the WHERE clause in an SQL statement

114. PostGIS

116. Raster Data

118. A grid coverage is a special case – the coverage forms a regular grid of features

119. This looks so much like “pixels” we end up using the same file formats (jpeg, png, tiff, etc..) with a text file for location

120. Spatial formats record location in file metadata (ecw, geotiff)

122. Height and Depth – Bathymetry

124. The file metadata can tell you what the values are for

126. Color

127. Multi-band

128. Style

131. Who will be using it?

133. Graphical Representation of Scale works even when altered/printed

136. Happy Face for planning lunch

138. Sequential

141. PointSymbolizer

142. LineSymbolizer

143. TextSymbolizer

144. RasterSymbolizer

145. Style Layer Descriptor – Mostly Ignore

146. FeatureTypeStyle – the Good Stuff

147. constraint Content Style Portrayal (ie Drawing) Composition line symbolizer line symbolizer point symbolizer text symbolizer NAME point symbolizer text symbolizer NAME point symbolizer Features Raster type=City type=Road constraint surface=hiway Rule max scale: 50k Rule Pop > 500000 max scale: 50k Rule Other Rule capital=true Rule Queanbeyan

149. From an XML file
