Course Summary

 Exercise 1

• Layout a local grid given line spacing, peg spacing and pegs per line
• Update attribute coordinates from survey data and add a column of sample numbers 
• Utilize a Planar transformation to convert a real-world projected map to a non-earth local grid
• Discuss requirements and processes involved to create an Affine transformation, and apply the resultant string to the MapInfow.Prj projection file  

Exercise 2

• Using Discover’s Key-In-Shapes module, complete an exercise in defining point, polyline and polygon objects
• Demonstrate how distance and bearing can be used for entry of a polyline
• Utilize Extract Nodes to extract both nodes and line segments from a polygon (tenement) boundary  

Exercise 3

• Digitise a series of lineament interpretations
• Determine line direction and update table with that information
• Use Proximity Search to create a buffer around selected lineaments and select nickel occurrences that fall within the buffer  

Exercise 4

• Given a table of structural points, use the Structural Symbols module to create oriented structural symbols
• Manually digitize a few symbols on-screen, using the structural symbol data entry dialog box  

Exercise 5

•  Use Line Annotation to annotate selected polylines with structural information  

Exercise 6

• Step through the process to build a colour look-up table from scratch
• Apply the colour look-up table to a map of geological polygons
• Discuss other methods to build colour look-up tables  

Exercise 7

• Utilize GraphMap to visually analyze a set of geochemical data  
• Produce multiple graphs of the sample dataset based on a key field (rock type)
• Complete exercises using Ternary diagrams, XY scatterplots, and distribution plots
• Discuss the Stereoplot and Rose diagram options  

Exercise 8

• Investigate the functions of the Geochem menu
• Complete exercises in point classification, data leveling, summary statistics and computing a correlation matrix  

Exercise 9

• Grid and contour a set of topographic data using the Surfaces menu
• Discuss various gridding methods and parameters that can adjusted
• Use the grid calculator to create a grid of overburden thickness
• Determine a volume to be stripped
• Investigate Voronoi polygons, grid filtering, grid profiles and grid import/export

Exercise 10

• Working with a raster dataset, complete a series of exercises with the Images menu
• Register an image using Discover Learn how to enhance, filter, clip, rotate and convert raster images  

Exercise 11

• A series of exercises dealing with drill plans and sections
• Setup a drill project, create a plan and a cross section
• Display downhole data on either side of a drill trace
• Build a colour look-up table for use with downhole drill data
• Create drill log
• Review the steps required to add a section to a scaled Layout Window
• Complete an exercise in boundary digitizing, determining a sectional resource, downhole compositing, determining maximum and end-of-hole values,  and validating a drill database

Depending on time and attendee interest, additional exercises can be worked on, as follows:  

Addenum A

• Examine Discover’s various Object Processing utilities
• Offset object, transform objects, thin by node number and position, donut polygons, clip to polygon, line cut, change line direction, and split multipolys  

Addenum B

•  Build objects from a table of X,Y coordinates
•  Discuss import and export features available in Discover
