Encouraging mining by dissemina6ng standard geological data easily accessible, using modern technologies. Strengthening African geoprocessing centers with development of spa6al databases as an instrument of management, standardiza6on and use of geological informa6on. Proposing new ways of obtaining geological data within the spa6al database business rules.

Main objec3ves

Specific objec3ves -‐ (1)

Dissemina6ng geoprocessing techniques, through courses, as a tool for GIS assembly, prin6ng layouts and data modeling in support for mineral prospec6on. Developing a geological GIS of a chosen pilot area in African con6nent aiming to gather a collec6on and to standardize data to compose a spa6al database that will be developed. Presen6ng as an intermediate product the previously selected pilot area data, organized in GIS and made available by freeware recorded on CD.


Organizing the data obtained from pilot area will generate the GIS and other products such as maps for prin6ng. Developing a spa6al database linked to standardized libraries of geological terms using Oracle ® or PostGree environments for the bases of chrono-‐lithostra6graphy, geological outcrops, mineral resources and macro structural geology. Forming a team to con6nue the development of other bases that may be necessary. Developing a Web portal with applica6ons that interact with ArcGis Server, allowing searches, data entry, map display, download and other facili6es in obtaining informa6on.


Star6ng the development of data entry applica6ons, according to the proposed libraries that are connected with the GEODATABASEs. Increasing the hardware park of geoprocessing centers through the acquisi6on of equipment. Increasing the number of soVwares available in geoprocessing centers through the acquisi6on of Oracle ®, ArcMap, ArcGis Server ® and freeware.

Pilot GIS and DATABASE development

Many people say that the best soVware is the one that we have mastered. We agree in part … Maybe, this is true for developing small things. However, the appropriate choice of good environments will increase or decrease the possibili6es for the formula6on of this final product or other future projects in geoprocessing and database.

Reasons for using ArcGis -‐ ESRI ®

• The popularity of the vector file format, the shapefile. • The facility in using the tool. • The power. The great amount of resources the environment has, such as: modeling and advanced geoprocessing. • The cost benefit for all these facili6es in a single environment. • The con6nuity of the soVware is always compa6ble with previous versions. • Procurement facility for non-‐profit ins6tu6ons such as UN etc. • The coverage and integra6on of data availability (ArcGIS Server, ArcGIS on line and other ESRI ® compa6ble environments).

The development environment for database modeling, proposed here, is the popular Oracle ®. Despite the high prices of its licenses, this environment ensures the development of the best and most complete database in the

World.

Database development


Security Tools

Documenta6on Capacity and possibili6es

The proposed database requires to store vector and raster en66es. Therefore, it is necessary to purchase Oracle ® spa6al cartridge and image cartridge. U6lizing these modules, it is possible to develop tables that store vector and image files in various formats. Likewise, through them it is feasible to make available the collec6on stored in map and image management

environments.


Despite the fact that Postgree PostGIS is a freeware and it can also be used in spa6al database development in the absence of

Oracle; The development consul6ng is oVen

expensive.

GIS construc3on Data integra3on and GIS of pilot area in Africa

Choice of pilot area and parameters sedng for GIS Requirements are: • To possess geological mapping with good maps made in appropriate scale, in paper or digital format. • To have registra6ons of geological outcrops, data recorded in field notes or organized into digital tables with la6tude and longitude. • To have registra6ons of mineral resources, data recorded in field notes or organized into digital tables with la6tude and longitude. • To possess other registra6ons as descrip6on of fossils, geochemical analysis, geochronological da6ng etc. All of them georeferenced, that means, located by la6tude and longitude.

Intermediate product GIS

Prepare the collec3on entry to load a database which will be modelled. (GEODATABASEs)

At this stage, some important parameters will be defined to guide the integra6on, namely simbology that defines geological database (leher symbols), ini6al scale of the work, choice of geological outcrops, mineral resources, global cartographic parameters, which will compose the GIS. Iden6fica6on and choice of other specific data that may par6cipate in the GIS, such as geochronological data, fossil etc.

Summary of development

Symbology proposal for the chrono-‐lithostra3graphic units of GIS

To determine the simbology regarding leher symbols of chrono-‐lithostra6graphic units. They will be u6lized in GIS and, aVerwards, in the database, since they will be part of the collec6on of LITHO base, when it has been modelled. The leher symbols should: • Be as factual as possible (not interpreted) • Contain no informa6on in duplicity. Once discussed, in specific workshops, and accepted, the proposed rules will be applied and used for all maps that will compose the GIS and, consequently, the database collec6on in its most diverse scales. This proposal is from a range of the best rules extracted from two proposals: the GEOBANK and GIS of South America.

GIS development

The leher symbol suggested is a composi6on of lehers and numbers. To facilitate GIS assembly ac6vi6es, two ways of representa6ng leher symbols have been established:

•  When the database is already modeled and there are record numbers of each symbolgy in the defini6ve database :

Age (1) + nature of the rock (2) + Record number (3) (defini;ve) •  When the database is not modeled yet and it is necessary to set a GIS to

start the modeling process, as this proposal establishes. In this case, there s6ll no record number in the database:

Age (1) + nature of the rock (2) + Ini;als of unit name (temporary)

There are situa6ons in which neither geochronological da6ng nor field researches permit the precise loca6on of chrono-‐lithostra6graphy unit in a certain Era, Period or Epoch of the Chronostra6graphic Chart. It is the typical case of some metamorphic core complexes involved in more than one termo-‐thectonic event, where the da6ng indicates many ages, depending on the sampled site. In this par6cular scenario, the age code is made with the juxtaposi6on of the codes of maximum age with the minimum age.

Proposal for the elabora3on of ahributes of GIS As previously stated, the GIS of the pilot area will contain ESRI format ahribute tables, organized into sets called GEODATABASE. This format will be modeling core of future database. (GEODATABASE is not the defini3ve database) Crhono-‐lithostra6graphy organized in chronolitho geodatase Outcrops organized in outcrop geodatabase Mineral resources organized in mineral resource geodatabase Machrostructural elements organized in structural geodabase Sample of geochemistry data organized in geochemistry geodatabase Petrography descrip6on data organized in petrography geodatabase

The data entry will be through tools built in the module MODEL BUILDER – ARCGIS . The area commands scripts. When executed they bind tables with ahributes to graphical en66es. This is due to the fact that the descrip6on of the ahributes are standardized with libraries of terms that must be obeyed. This is a way to make it easier. But, other methods may also be used at this stage.

This is the most important step when crea6ng a database. Here, the ahributes of the Oracle® table will be created, and connected to the library of terms. OVen, these tables, with their respec6ve library, are the same ones already made for GIS. Some are similar to GEOBANK, ins6tu6onal database of Geological Survey of Brazil, and others will be created from local discussions.

Geology bases


Chrono-‐lithostra/graphy – base cons6tuted of geological classes catalog and their main ahributes, being the leher symbol and scale one of the most important. Other ahributes are: rocks, metamorphic grade, ages or age range. It will be linked to geological polygons in spacial environment. Support libraries: rocks, metamorphic grade, geological age, etc. The items of this base are oVen organized into affilia6on arrangements between classes, as supergroup, groups and forma6ons, members, beds, facies for sedimentary rocks; suite and body for igneous rock; complex, unit or sequence and lithofacies for metamorphic rocks, etc. Its modeling will take place from CRONOLITHO GEODATABASE. Geological outcrops – point base composed of descrip6on of geological outcrop located by their la6tudes and longitudes. It will be linked to the geological outcrop points. Support library: rocks, structural geology, etc. Existence of textual field where there is the outcrop descrip6on made by the field geologist. The modeling of this base will be started from OUTCROP GEODATABASE.

Geology bases



Mineral resources – point base with the descrip6on of mineral resources, iden6fied by la6tude and longitude. It will be linked to the mineral resource points. Support library: status, rocks, substances etc. Mines, mineral occurrences and garimpos will be found here. Its modeling willtake place from MINERAL RESOURCES GEODATABASE. Structural base of faults, fractures and linea/ons – this base consists of faults, fractures and linea6ons descrip6on, using the strike, slip, dip and other parameters. Base linked to linear en66es. Various support libraries. The modeling of this base will started from STRUCTURAL GEODATABASE. Other bases – different bases, both with direct input and for storing data obtained through interac6on of exis6ng data. It is important to emphasize the polygonal collec6on corresponding to files of polygon, polylines and points , in shapefile format, worked during the GIS stage, it will also migrate to tables under Oracle ® spacial cartridge. The images will compose the base of image of the database. These files will be stored in tables under Oracle ® image cartridge.
