2 Analyse The analysis and examination of geochemical and structural datasets can add significant value to your data. Our analytical tools are state-of-the-art, capable of revealing trends and associations that would not otherwise be apparent with traditional methods of analysis. Discover provides an extensive range of statistical, geostatistical, graphical, modelling, and visualisation tools that will help you to recognise trends and anomalies in multi-variate data acquired from multiple sources. And just as importantly, Discover will assist you with identifying and eliminating false anomalies that can arise from sampling and assaying errors or geological bias. In addition to the more specialised geostatistical, gridding, and modelling tools available, Discover employs a broad spectrum of general-purpose spatial, statistical, and graphical techniques for analysing and classifying populations. And, because these computational tools are all integrated with and complemented by the underlying mapping and visualisation capabilities of the Discover MapInfo GIS platform, the entire process is completely seamless and very efficient. Spatial Thematic mapping MapInfo s renowned system of data classification. Point classification Modulate point size, colour, and symbol with statistical ranging. Trivariate mapping Examine multi-variate relationships. Stacked profiles Identify spatial trends with linegraphs and profiles. Change mapping Compute and display changes in area and perimeter. Geo-located graphs Geo-locate graphs of table data in the map window for example, scatter plots of geochemistry at the hole collar, or linegraphs of pollutant levels over time at monitoring sites. Vector plotting Display magnitude and orientation of vectors for example, slope stability monitoring and pollutant flows.

3 Statistical Summary statistics for selected vector data populations Calculation of correlation coefficients Data levelling and transformations to assist in the detection of anomalous samples and remove sampling and geological-bias On-the-fly selection with statistical graphing and reports Detailed statistics calculation for each polygonal region over a gridded surface Graphical Select, display, and report geochemical and structural data simultaneously in multiple views and graphs. 2D and 3D scatter Scatter matrix Probability Lines Bar Bubble Map Histogram Box and Wisker Pie Rose Ternary Stereogram Key functions Group data by attribute field (e.g. soil mesh size) and display in the same or separate graphs. Insert dynamic graphs in a map window to display additional spatial, statistical, or temporal information. Modulate colour, size, and symbol by userdefined or statistically ranged bins. Precondition data to remove null values and nugget effects. Select data in any table, map window, or graph, and view the selection in all open or linked tables, maps, and graphs. Graphs and reports are dynamically updated with each selection. Define derived fields with mathematical, logical, and statistical operators.

4 Model Discover provides a comprehensive set of surface gridding tools suitable for modelling, contouring, and visualising any type of data from geochemical, geophysical, hydrogeological, meteorological, topographic, chemical, and environmental surveys. Choose from the wide selection of gridding algorithms to create surface models from located point, line and region values. The resulting grid values can be queried and modified with a versatile collection of transformation tools. Compute curvature, slope, aspect, volumes, and other surface properties, or use the versatile grid calulator to derive values from user-defined expressions. Key functions Minimum-curvature, IDW, triangulation, and nearest-neighbour algorithms Ordinary and simple kriging for point and block estimation Density and distance methods Extensive data pre-conditioning controls (e.g. null value removal) Statistical analysis Variogram analysis Breakline support for modelling surface discontinuities, such as cliff tops and fault lines Optimal parameter selection Red-green -blue channel output Smoothing, clipping, and coincident point controls Voronoi polygons Visualise The Discover MapInfo GIS provides outstanding grid visualisation options, and at a map-making standard. Map-quality contouring with sophisticated contour labelling controls Grid colour modulation by linear distribution, histogram equalisation, percentile and data breaks, or user-defined Dynamic sun-shading with single or dual light sources ideal for detecting subtle trends in aeromagnetic grids Generate multiple profiles across multiple grids draped with polygon and polyline datasets ideal for combined sectional analysis of, for example, geochemical grids, geological mapping and fault traces.

5 Very Large Grids With Discover you can confidently import, display, and modify massive grids, such as the multiple gigabyte grids used for continental SRTM data. The program architecture is designed to not just allow you open these very large grids, but also gives you instantaneous zoom and pan capability. You can also divide the grid into smaller tiles, or clip the grid around your area of interest. Query Interrogate individual grid cells or select a group of cells that lie within a data range, or multiple data ranges, or by slope angle, elevation, and aspect. Extract, Modify, and Compute An extensive and functional set of grid manipulation tools is provided to simplify the tasks of managing, modifying, transforming, and extracting information from grids. Extract and output assign values from grid classify cells create RGB images vectorise Modify and transform convert clip edit fill holes flip Computations curvature statistics slope and aspect surface area merge outline overlay replace reproject view-shed volume between two grids volume between grid and datum cut and fill volume resample rotate shift split Grid Calculator The Discover grid calculator makes complex grid arithmetic, statistical computations, and Boolean operations easy to perform simultaneously on one or more grids. Grid Filters A comprehensive selection of smoothing, enhancement, average, sun-angle, user-defined, band pass, continuation, reduction to pole, reduction to equator, and vertical derivative filters are available.

6 Capture With Discover you can accurately and efficiently capture spatial information from historical maps for the evaluation of sampling data, grid creation, or to enhance maps and sections. Discover s sophisticated digitizing and object editing tools will ensure that you maximise the value of all forms of data, both electronic and physical. Form donuts and cut-outs within bounding polygons. Build polygons from overlapping linework with sophisticated orphan, gap, loop, and overlap controls. Digitise Discover simplifies digitising of geological, regolith, and area usage polygons by intelligently converting disconnected assemblies of digitised linework into attributed polygon vector objects. Discover automatically checks and cleans the linework, resolving gaps, overlaps, and loops, and streamlines the process of adding attributes to the resulting polygons. While you digitize, Discover can auto-increment integer attributes (e.g. sample numbers), auto-fill text or numeric attributes, and prompt for other location-specific data. Combine this with the extensive and customisable styles library of geoscience-specific objects, and you have a simple and efficient data capture tool for converting historical imaged data into usable vector data. Digitised points, lines, and polygons are graphically rendered by applying customised colour and pattern style tables. New styles can be created from existing maps (e.g. AGSO polygon maps) and made available to other users in the organisation through a common styles library. Key capabilities Auto-increment and auto-fill values in attribute fields. Build polygons from overlapping linework with sophisticated orphan, gap, loop, and overlap controls. Edit Discover gives you an extensive set of productivity tools for editing, cleaning, transforming, and manipulating map objects. Key functions Edit, reverse, smooth, and thin nodes in one or more objects. Create and edit nodes from the keyboard or cursor. Copy styles from one object and apply to others. Align, rotate, shift, and rescale groups of objects. Duplicate an object into a gridded array. Concatenate, trim, cut, clip, and split multiple objects.

7 Maps Make professional maps of any size and scale incorporating all related spatial data objects, filtered and sun-shaded grids, contours, graphics overlays, geo-located raster images, structural symbols, legends, graphs, tables, scale bars, and other mapping objects. Map-Making Wizard Use Discover s map-making wizard to quickly create professional, standardised maps. The wizard takes you step-by-step through each decision on scale, paper size, map grid style, title block, scale bar, and other map options. Key functions Customise title blocks Customise map legends for example, geological units by chronological order Set text size according to scale independent of the map window Control format, orientation, and colour of text labels from a legend Update text labels from data tables and vice versa Line annotations, including standard fault and fold symbology Add line and point labels to local grid data Rectification of Raster Images Discover prevents errors being introduced into your exploration programme by ensuring all scanned imagery from open-file reports and other sources is accurately registered. Images are rubber-sheeted (rectified) into their correct spatial location by warping, skewing, and stretching the source image to fit the known control points. You can also reproject georeferenced images to a new projection, ensuring that all data shares a common projection, and thereby solve the exploration geologist s nightmare of working with multiple projections in the same dataset. Key functions Image rectification Image reprojection Image clipping Image filtering and enhancement Structural Symbol Library Display existing or create new structural data as orientated structural symbols using Discover s library of Australian (AGSO), Canadian (GSC), and USA (USGS) structural symbols.
