GIS for Geosciences
Encom Discover is the desktop Geographical
Information System (GIS) designed especially
for the geosciences, providing the tools you
need to effectively compile, visualise, analyse,
and map spatial geoscience data. Since
its release in 1994, Discover with MapInfo
Professional has become the GIS of choice
for geologists, environmental scientists,
cartographers, exploration managers, and
database administrators. Discover is the ‘must
have’ application for geoscientists worldwide.


Maximise the Value of Your Data
More than in any other industry, Natural
Resources businesses rely on their technical
data to successfully locate, evaluate, and develop
their primary assets. And they spend a lot of
money to acquire this business-critical data. So
make sure that you get the full value from your
investment by using the right software. Discover
does this by integrating data from multiple
sources in a unified geospatial environment and
then providing your specialists with leading-edge
tools in a powerful, yet easy-to-use, framework.


Unlock the Power of MapInfo
With its extensive range of features customised
for geoscience applications, Discover
unlocks the power of MapInfo Professional
for geologists and other geoscience
professionals. Combined, Discover and
MapInfo Professional deliver a perfect
balance of general-purpose GIS functionality
and specialised geoscience capabilities.
Analyse

The analysis and examination of geochemical, structural
and temporal 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.

Model

Discover provides a comprehensive set of surface gridding
tools suitable for modelling, contouring, and visualising any
type of data from geochemical, geophysical, hydrological,
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 and 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

Very Large Grids
With Discover you can create, import, display, and modify
multiple-gigabyte grids, such as continental-scale SRTM
data. Zoom and pan around these massive grids in real
time, modify their appearance, and process, manipulate
and analyze them with many of the grid utilities.

Hydrology toolbox
Automatically extract drainage features from gridded
digital elevation surfaces, including vectorisation of
watershed/catchments, stream junctions and networks.
Indispensable for the environmental monitoring, water
management, exploration and engineering fields.
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.

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.
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.

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.

• Form donuts and cut-outs within bounding polygons.

  who often need to analyze data along non linear
  sections such as pipe lines, roads, tunnels and
  subsurface palaeochannels or aquifers

• Create log plots for ultra-detailed downhole
  multi-assay and attribute analysis.

• Customise your downhole data display to
  show precisely what you want and where
  you want it, with complete control over text
  labels, linegraphs, histograms, colour, pattern,
  and orientated structural symbols.

• Integrate surface geology mapping, topography, and
  other surfaces, such as geochemistry and geophysics.

• Create custom legend tables for
  numeric and attribute datasets.

• Create professional hard-copy with an intuitive wizard
  that ensures a precise output scale, and optionally
  adds annotated grids, scalebars, and title blocks.

Interpret, Composite, Estimate
• Digitise geological and other interpretations directly
  on to sections, and export as 3D DXF vector files
  for use in mining applications or Discover 3D.
Integrate

Discover is designed to work with your special-purpose design, modelling, analysis, and planning systems. By making data accessible
to personnel across your entire organisation, your project teams are better able to visualise, communicate, and collaborate.

Read and write data in over 90 industry-standard database, image, vector, and grid formats, plus a range of vector conversion options.
