1 Programa de Pós- Graduação em Ciência da Computação A spa&al data infrastructure for the Project GeoMINAS Lucas F. M. Vegi Jugurta Lisboa F. Wagner D. Souza João P.C. Lamas Glauber L. S. Costa Wellington M. Oliveira Rafael S. Carrasco Tiago G. Ferreira Joás W. Baia

2 Concepts Outline Mo&va&on: The GeoMINAS website Objec&ve The SDI GeoMINAS GeoNetwork and I3Geo Configura&on Acquisi&on of Geospa&al Data Elabora&on of the Metadata with the MGB Profile Final Considera&ons

3 Spa&al Data Infrastructure Spa9al Data Infrastructure (SDI) is a set of technologies, policies, standards and human resources necessary to acquire, process, store, distribute, and improve u&liza&on of geospa&al data. (Execu&ve Order of US, 1994)

4 INDE and MGB Profile The Comissão Nacional de Cartografia (CONCAR) ins&tuted the Infraestrutura Nacional de Dados Espaciais (INDE) - Na&onal Spa&al Data Infrastructure in 2008 (CONCAR, 2010). MGB Profile - Brazilian Profile for geographic metadata in line with the interna&onal standard for metadata ISO 19115:2003

5 Mo&va&on: The GeoMINAS website The GeoMINAS website was a good example of ini&a&ve to provide geospa9al data. Was created in 1995 by some ins&tu&ons of the Minas Gerais state. hep:// Metadata didn t followed standards. Due to the lack of poli9cal support, the GeoMINAS website didn t receive updates and ended in April Its data were widely used by users all around Brazil during its 15 years of existence.

7 Obje&ve Restructure the old GeoMINAS website, crea9ng a SDI which recover their original data and document them through metadata following the Brazilian metadata standard (MGB Profile).

8 The SDI GeoMINAS The SDI GeoMINAS is a project developed at Federal University of Viçosa (UFV). Its crea&on was structured in three groups of collabora&ve work: Responsible for recovery and conversion of geographic data; Responsible for the elabora&on of metadata; Responsible for the customiza&on of the metadata catalog (GeoNetwork).

9 GeoNetwork The GeoNetwork provides cataloging and access to content from various types of data through metadata based on several standards: ISO > MGB ISO19139 FGDC Dublin Core This system is widely used in ini&a&ves of SDI in the world, for example: INDE Scohsh Spa&al Data Infrastructure

10 GeoNetwork Configura&on We are using the version 2.2 of GeoNetwork, available on the IBGE website, because it has support for the MGB profile. Since GeoNetwork runs on an applica&on server with support for Java and Servlets, we have used in this project the Apache Tomcat applica&on server.

11 GeoNetwork Configura&on By default, the GeoNetwork is delivered pre- configured with Database Management System (DBMS) Mckoi SQL. however it supports several other DBMSs such as PostgreSQL, MySQL, Oracle and SQLServer. In this project we chose to use MySQL because of the seungs of the hos9ng servers used.

12 GeoNetwork Configura&on The GeoNetwork is integrated with two other sojware, the Geoserver and Intermap. They assist in the spa9al searching, showing an interac&ve map where the user can select and amplify a region of interest for search data.

15 I3Geo In addi&on to providing data for download, SDI GeoMINAS enables the visualiza9on of data directly from the browser by using the integrated sojware I3Geo. The I3Geo was developed by the Ministério do Meio Ambiente (the Brazilian ministry responsible for the environment) mainly based on MapServer.

16 Acquisi&on of Geospa&al Data Since the old GeoMINAS website is offline, we have tried to find copies of the original data from alterna9ve sources. We have analyzed and used four different sources: Website of the spa&al database course from the Department of Computer Science of UFMG (DBMS PostGIS) A company of Viçosa- MG, called iplanus, where we obtained a par&al copy of the data, with about 70Mb Department of Soils of the UFV (complete copy of the data) A server at INPE, where we obtained 13 Mb of data (format of the sojware Spring)

17 Acquisi&on of Geospa&al Data The acquired data are classified into six main categories: Agriculture Protected Areas (reforesta&on) Climate and Weather (rates of precipita&on) Hydrology and Hydrography Poli&cal- Administra&ve Boundaries Basic Geographic Mapping

18 Elabora&on of the Metadata with the MGB Profile The elabora&on of the metadata was done manually using the GeoNetwork metadata editor. The Informa9on about the original metadata was first collected from the data descrip9on file of the old GeoMINAS website. The Quantum GIS sojware was used to collect the coordinate of the limits (bounding box) and the reference system for each shape file.

19 Elabora&on of the Metadata with the MGB Profile The metadata 9tles contained in the descrip&on have been changed to a label that iden&fy beeer the data and assists in its recovery. E.g.: The name for the spa&al data "MG.TAB" was changed to "Outline of the State of Minas Gerais (MG.TAB)".

20 Elabora&on of the Metadata with the MGB Profile

21 Final Considera&ons With the SDI GeoMINAS the data repository is no longer sta9c and provides an environment where users can easily publish their data. As a future work, we will develop new Web services and try to integrate the SDI GeoMINAS with the INDE, as another node of the geospa&al data server network.
