GIS Training for the mineral exploration and mining industry
Geographic Informaton System (GIS) is the most powerful tool for organising, managing and making sense of large amounts of spatial data. For this reason it has become a key factor in the mineral exploration and mining industry, where managing the data generated by a project can be demanding and time-consuming.
Kenex is well aware that every project and company has different skill sets and objectives. General GIS understanding is important, but needs to target the actual work you want to get done. Kenex can tailor your training to ensure you learn what you need in the most efficient way, using the software you prefer, and the tools and knowledge you already have. We use industry-standard spatial software and are able to assist geoscientists in each step of creating their GIS: from digitising and collecting data to performing spatial analyses, generating spatial predictive models, and finally organizing the data in relationa- spatial databases. Furthermore, we are able to create basic corporate-focussed GIS viewers for management, to aid the presentation of project data during fundraising meetings, as well as potential joint venture and farm-in discussions.
The development of a GIS can be articulated in the following steps:
Data compilation: Being able to collect data from numerous different sources is a paramount skill for a successful compilation. Kenex can guide geoscientists through the process of importing data from different table formats, digitizing data from maps and reports with the best possible accuracy, and organizing the results effectively. This allows the trainee to learn:
- Workspace settings
- Geographic datum and projections
- Data editing
- Data importing and exporting
- Map making
- Spatial analysis: The real value of a GIS becomes evident when the collected data is interpreted. More advanced GIS skills are necessary for processing digital data to extract value from it. Examples include interpolating results from geochemical sampling, analysing digital satellite images to produce interpreted maps of vegetation cover or lithology, or deriving slope information and catchment shapes from elevation.
Kenex can help the trainee to learn the basics of spatial analysis, such as:
- Data selection and queries
- Raster images interpolation
- Raster reclassification Surface analyses
- Raster statistics
- Vector spatial analysis and manipulation
Predictive modelling: Basic statistical interpolation allows you to predict unknown values from within a single layer such as topography, geochemistry or hydrology. However the real power of GIS becomes apparent when spatial modelling combines several different layers into a predictive model based on probability. A successful predictive model needs to take into account of how influental a particular thematic layer is, related to the occurrences being modelled, and then combine all the themes weighted according to their importance to make the prediction. The result of a predictive model is a probability map that shows the likelihood of an occurrence being present in any given area. Kenex specialises in predictive modelling and can offer training covering the following topics:
- What is prospectivity modelling and how is it used in mineral exploration
- Exploration models compared to genetic models
- Software, tools and basic GIS techniques
- Spatial data analysis, spatial data correlations and the exploration model
- Prospectivity models using fuzzy logic, weights of evidence and neural networks
- Using the prospectivity modelling results for exploration targeting and planning
- GIS Database creation and maintenance: GIS databases are the core of any geographic information system. Being able to handle the often overwhelming amount of data that a mineral project can produce and organise it in a functional database, is probably the most important factor for creating a complete and efficient GIS. Well-constructed geodatabases allow users to quickly visualise spatial data with all their attributes and relations to tabular data. An example is displaying drill hole locations and their related logs and assay results, and produce maps and reports of grade distribution with minimum effort. Kenex has more than ten years of experience in creating and managing large and complex spatial databases. Our own databases store millions of geochemistry records plus digital geological, topographic and cadastral information from all around the world, which are the basis of all our GIS projects. Kenex can therefore also help the trainee in:
- Understanding the basics of relational databases
- Creating database schemas that suit your business
- Working with relationships, unique keys and foreign keys
- Importing and exporting data Assigning login and permissions to the spatial table
- Visualising the data and their attributes in a GIS software
