1. Sharing Data in the Age of the GeoWeb James Fee - WeoGeo.com
2. Sharing Your Spatial Data
3. Sharing Your Spatial Data or
4. Sharing Your Spatial Data or How to Push Your GIS Files Through a Round Hole and Live to Tell About it!
5. If Sharing
   is Easy... http://www.flickr.com/photos/13586721@N05/3122021735/
6. Why is it so hard to share spatial data?
7. Data Interoperability
8. Data Interoperability Data Portals...
9. Build it and they will use it!?!?
27. Lets make this simple...
28. Just give me a shapefile
30. california.shp california.shx california.dbf
31. california.shp california.shx california.dbf california.prj california.shp.xml
32. california.shp california.shx california.dbf california.prj california.shp.xml california.sbn california.sbx california.ain california.aih california.ixs california.mxs california.atx california.cpg
33. california.shp california.shx california.dbf california.prj california.shp.xml california.sbn california.sbx california.ain california.aih california.ixs california.mxs california.atx california.cpg
38. Can We Come Up With a Standard?
39. What would work?
40. What would work? open database
41. What would work? open database open symbology
42. What would work? open database open symbology platform support
43. What would work? open database open symbology platform support OGC support*
44. ESRI’s File Geodatabase
45. ESRI’s File Geodatabase
46. So just give me a File Geodatabase
50. Users Demand Format Agnosticism
51. Users Demand Format Agnosticism • Freedom to use any application
52. Users Demand Format Agnosticism • Freedom to use any application • Open formats
53. Users Demand Format Agnosticism • Freedom to use any application • Open formats • User ownership of data
54. So we need an open spatial database format
58. I really want to get me some of that!

78. Community Driven Standards
79. Community Driven Standards Users drive formats
80. How do we share?
81. Layer Package to the Rescue
82. Layer Package to the Rescue
83. What Works for the Layer Package
84. What Works for the Layer Package •Compressed format shares well
85. What Works for the Layer Package •Compressed format shares well •Includes symbology
86. What Works for the Layer Package •Compressed format shares well •Includes symbology •Metadata and preview thumbnails
87. What Works for the Layer Package •Compressed format shares well •Includes symbology •Metadata and preview thumbnails •Easy to create with ArcMap
88. Problems with the Layer Package
89. Problems with the Layer Package •Uses the closed ESRI Layer file for symbology
90. Problems with the Layer Package •Uses the closed ESRI Layer file for symbology •Some files converted to closed File Geodatabase format
91. Problems with the Layer Package •Uses the closed ESRI Layer file for symbology •Some files converted to closed File Geodatabase format •Undocumented
92. We need symbology with our datasets
93. Options:
94. Options: SLD/SE
95. CSS Options: SLD/SE
96. Enter GSS
97. Enter GSS Based on: &
98. Enter GSS Based on: & Handles dynamic data sources
99. Enter GSS Based on: & Handles dynamic data sources Designed to work with
100. Example GSS body: { fillStyle: "#f6f6f6", lineWidth: 0 }, node: { fillStyle: "#ddd", strokeStyle: "#090", lineWidth: 0, radius: 1 }, way: { strokeStyle: function() { return "#"+ (parseInt((this.user), 36).toString(16)+"000000").truncate(6,"" ) }, lineWidth: function() { if (this.tags.get('width')) return parseInt(this.tags.get('width')) else return 1 }, fillStyle: "white"
