Transcript

1. Data Interoperability on the GeoWeb James Fee Evangelist
2. If Sharing
   is Easy... http://www.flickr.com/photos/13586721@N05/3122021735/
3. Why is it so hard to share spatial data?
4. What about spatial data standards?
5. Community Driven Standards
6. Just give me a shapefile
8. portland.shp portland.shx portland.dbf
9. portland.shp portland.shx portland.dbf portland.prj portland.shp.xml
10. portland.shp portland.shx portland.dbf portland.prj portland.shp.xml portland.sbn portland.sbx portland.ain portland.aih portland.ixs portland.mxs portland.atx portland.cpg
11. portland.shp portland.shx portland.dbf portland.prj portland.shp.xml portland.sbn portland.sbx portland.ain portland.aih portland.ixs portland.mxs portland.atx portland.cpg
16. Can We Come Up With a Standard?
17. What would work?
18. What would work? open database
19. What would work? open database open symbology
20. What would work? open database open symbology OGC support
21. What would work? open database open symbology OGC support platform support
22. ESRI’s File Geodatabase
23. ESRI’s File Geodatabase
24. So just give me a File Geodatabase
28. So we need an open spatial database format
32. I really want to get me some of that!
34. ‣ All the benefits of Shapefiles ‣ Open ‣ Easy to use
35. ‣ All the benefits of Shapefiles ‣ Open ‣ Easy to use ‣ None of the limitations ‣ Multiple files ‣ Limited field widths
36. Problems with SQLite?
37. •No support from ESRI Problems with SQLite?
38. •No support from ESRI •Still not well known in the community Problems with SQLite?
39. SpatiaLite
40. SpatiaLite •Built on SQLite RDBMS
41. SpatiaLite •Built on SQLite RDBMS •Just a file
42. SpatiaLite •Built on SQLite RDBMS •Just a file •Portable - Works on Windows, Linux or Mac OS X
43. SpatiaLite •Built on SQLite RDBMS •Just a file •Portable - Works on Windows, Linux or Mac OS X •Implements OGC Simple Features for SQL
44. Community Driven Standards
45. Community Driven Standards Users drive formats
46. How do we share?
47. Layer Package to the Rescue
48. Layer Package to the Rescue
49. What Works for the Layer Package
50. What Works for the Layer Package •Compressed format shares well
51. What Works for the Layer Package •Compressed format shares well •Includes symbology
52. What Works for the Layer Package •Compressed format shares well •Includes symbology •Metadata and preview thumbnails
53. What Works for the Layer Package •Compressed format shares well •Includes symbology •Metadata and preview thumbnails •Easy to create with ArcMap
54. Problems with the Layer Package
55. Problems with the Layer Package •Uses the closed ESRI Layer file for symbology
56. Problems with the Layer Package •Uses the closed ESRI Layer file for symbology •Some files converted to closed File Geodatabase format
57. Problems with the Layer Package •Uses the closed ESRI Layer file for symbology •Some files converted to closed File Geodatabase format •Undocumented
58. We need symbology with our datasets
59. Options:
60. Options: SLD/SE
61. CSS Options: SLD/SE
63. Put my symbology in a sidecar!
64. portland.sqlite portland.css
65. Atom, GeoRSS, GeoJSON
    
66. Atom, GeoRSS, GeoJSON
    SQLite Spatial SpatiaLite CSS for Symbology
    
67. Making data discoverable
68. Spatial Data Can Be
69. Secure Sensitive Open Spatial Data Can Be
70. Availability During Disasters
71. Monetize Where Possible
72. Picking Formats and
 Target Audience

75. Citizen Participation
    San Diego Fires
77. Sharing Large Datasets
78. Sharing Large Datasets
79. Sharing Large Datasets
80. Sharing Large Datasets
81. So what about vectors?
82. So what about vectors?
83. So what about vectors?
84. So what about vectors? 125 GB
89. Selecting Vectors to Download 1.Zoom to your area of interest 2.Draw polygon for selection 3.Query
90. Vectors in WeoGeo
91. Vectors in WeoGeo C o m i n g S o o n !
92. What does data interoperability give us?
93. Breaking Through Stacks
94. Closed formats should be avoided
99. Archiving Geo Data
100. How Will People Use Your Data in 10 years?
101. It Was 1998...
103. James was coding up some cutting edge ESRI MapObjects and FoxPro Magic
104. Data Archival Systems: 1999
105. My Old Computer is Dead
106. If only I had archived in a non-proprietary format...
107. Ways to keep this from happening to with your data... Use Open Formats Use ETL Pray
108. Fight for your right to use open spatial data standards
109. Thank You James Fee email: jfee@weogeo.com twitter: @cageyjames blog: http://www.spatiallyadjusted.com mobile: 480.225.2287
