1. Migrating geographic information
systems to open source in the
Brazilian Federal Police

2. Inteligeo
● Is a system created by the Brazilian Federal Police
● Focus on providing experts with data to produce forensic
reports
● Is part of a larger initiative that involves training,
procurement and services for the entire Federal Police
● Is managed by AGEO/INC/DITEC/PF

3. Inteligeo
● Since 2009
● Centralized raster and vector database
● Support data for forensic reports
– Imagery
– Vector data
● Tools for searching, processing and displaying the
data
● Administrative information overlays

4. Sponsors
● JICA
– Initial investment, consulting, training. Long term success commitment.
– ALOS project (Jica President Award – best 4 projects in the world)
● FINEP
– Research on open source software usage
– ISPRS2012 (2 articles)
– EAFS2012
– Foss4g 2011
– Foss4g 2014 (2 presentations)
● UNODC
– PEQUI – Drug “DNA”
– SIGMA – Marijuana GIS
● DITEC – INC
– Personnel, equipment, infrastructure, operations, continued support.

8. Migration to FOSS
● We have been migrating since 2010
● Why change to FOSS?
– Strategic control of data
– Infrastructure integration
– Lifecycle cost
– Strategic control of software
– Technical superiority

9. Starting point
● Sponsored by JICA
● Built following a model from IBAMA's SISCOM
● Stack:
– CentOS
– ArcSDE on PostgreSQL
– ArcGIS Server
– Web application based on ESRI's FlexViewer
– Administration using ArcGIS Desktop

10. Step 1 (circa 2012)
● Migrate database to plain PostgreSQL+Postgis
● Rebuild all ArcGIS project files to point to that
– Esri support helped us make a direct connection without SDE
● Relinquish any compatibility guarantee
● Work around the caveats
– Long field names
– Unsupported field types
– ArcGIS' attempts to change the database upon connection
– Necessary to build views for some tables

11. Step 2 (2013-2014)
● Implement functionality that was previously being held back by the
database
– Integration with the forensic reports system
– Daily uploads of other institutions data
– Protocols for loading the image catalog footprints and metadata
– Protocols for producing geoprocessing products directly on the database
● Train people to use QGIS
● Write a script for automatic QGIS configuration
● wiki.osgeo.org/wiki/Brazilian_Coordinate_Reference_Systems

12. Step 3 (2015 - 2017)
● Develop a new web interface using only open source
code
● Choose a new open source middleware
– QGIS Server (great styling)
– Mapserver (great speed)
– Geoserver (great functionality)
– I3GEO/Mapserver (great user base in our government)
● We picked Geoserver mainly because of
authentication and ease of management.

13. What is new?
● Inteligeo 4.0 and 4.1 web interfaces
● Wiki web portal for documentation
● Geoserver implementation
● Initial tests for storing restricted data
● Huge image contract
● Providing image request services
● Creation of the Geomatics Area of the National Institute of Criminalistics
● Lots of work on migrating 850 layer styles to Geoserver (grind on the REST
api, geoserver bugs, hierarchy, metadata)
● Lots of Qgis training (10 courses in 2 years)
● Foss4g 2018 – Dar Es Salaam: redo half of the work on Geoserver

[qgis configuration]
[forensic reports]

16. Next steps
● Finish Geoserver migration
● Decomission ArcGis Server
● Add features to Inteligeo 4.1
● Metadata overhaul
● Database overhaul
● New data warehousing protocols
● INDE publication
● Cleanup code for open sourcing
● New facilities for the team
