I am planning a regional exploration work program. What tools are available in Discover?

Occurrence

How do I:

A. Add coordinates to a series of discrete point locations such as proposed regional RAB/aircore drill targets, and then add an incrementing identifier (e.g. HoleID) to each location?

B. Convert a series of proposed regional traverse lines/polylines into grid pegs/sample locations at a fixed spacing, each with coordinates and unique ID's?

C. Create a series of parallel traverse/sample line (i.e. a local grid), with pegs/point locations at fixed spacings, each with both local and real world coordinates, as well as unique ID's?

   




Solution

A. Add coordinates to a series of discrete point locations such as proposed regional RAB/aircore drill targets, and then add an incrementing identifier (e.g. HoleID) to each location?

1/. If a series of target locations have been added to say the cosmetic layer as points (e.g. the intersection of regional lineaments/faults with prospective stratigraphy), save these point objects to a new table (Map>Save Cosmetic Objects).



2/. Use Discover's Data Utilities>Update Coordinates tool to create a new Easting/X and Northing/Y field to this table, and automatically populate these fields with the appropriate values. Note that by default the coordinates will be captured in the Projection of the map window; use the Other Projection option to change the projection the output coordinates will be displayed in.



3/. Use Discover's Table Utilities>Add Unique Identifier to populate each record with an incrementing ID value. See the related article discussing this in detail.





B. Convert a series of proposed regional traverse lines/polylines into grid pegs/sample locations at a fixed spacing, each with coordinates and unique ID's?

1/. If a series of proposed sample traverses have been added to say the cosmetic layer as lines or polylines, save these to a new table (Map>Save Cosmetic Objects).

2/. If each traverse line is to be named, add a new field (Table>Maintenance>Table Structure, and add say a Character field of 20 width called Line_Name). Attribute each line as necessary. Save these changes (
File>Save  Table).

3/.  Use  the Discover's Object Editing>Insert Nodes tool to  insert nodes at  the required distance along each traverse line (e.g. 50m).
Save  these changes (File>Save  Table)




4/. Select all the lines of interest, and run Discover's Data Utilities>Extract Nodes tool.



5
/. Use Discover 10's Table Utilities>Add Unique Identifier to populate each record with an incrementing ID value. See the related article discussing this in detail.



C. Create a series of parallel traverse/sample line (i.e. a local grid), with pegs/point locations at fixed spacings, each with both local and real world coordinates, as well as unqiue ID's?

    Use Discover 10's new interactive Local Grid Layout tool (under the Data Utilities menu).
