Big Data Tools - Pros and Cons
• Are they representative of reality ?• Do they show any
relevant trending ?• More Social Networks must be included• Do
local authorities care about this tools ?
- I.E. Bogotá is working with linked data
-
Big Data Technology - Pros and Cons
• Is not all about Volume (Velocity and Variability)
• CSV Storage problems with Special Characters ( , \n . )• Date
format and time zone
- Directly to Geodatabase
• Word Count API is not fully developed- Code it
• Graphs and maps does not show the hole history- Try, Try, Try,
….
-
Future Works
• Linked Data for interoperability• GIS to RDF translation
(@dianazul)• Multiple City Estimation and Comparison• Business
Model for consultancy• ArcGIS Toolbox like spatio-temporal cubes•
Zoning and grid processing• Share and test this development
