GEOVIA Surpac: Complete Training from Survey To Estimation

Import csv survey data into subpack and generate a topography string for plan view. Contour the data by defining extents, triangulating, and applying SSI styles with index contours.

Create a dtm from contours by converting to a 3d dm from a string file, view it as a 3d solid, and validate brake lines and spot heights.

Learn how to calculate volumes between two DTMs in Geovia Surpac, including net volume and cut-and-fill, using boundary strings and CSV reports.

Create DM sections automatically in Geovia Surpac by defining an axis with a 2d grid at 50 m intervals. Generate sections along the axis.

Perform a 2d coordinate transformation in Geovia Surpac by using two reference points, importing a string file, and generating a query with scale, rotation, and x/y shifts for local coordinates.

Explore drillhole data management in Surpac, linking borehole coordinates (x, y, z), maximum depth, dip, and azimuth to color, survey, geology, and assay tables to model ore bodies in 3D.

Learn to create a drillhole database in Surpac, using mandatory color and survey tables alongside optional geology and assay data to visualize drill holes in 3D.

Import data to the database by mapping color, survey, assay, and geology tables, checking for errors, and using a translation table to replace Na with minus one.

Compare explicit geological modeling, built by manual digitizing and linear interpolation between sections, with implicit modeling using an rbf surface. Note Subpac currently lacks implicit tools.

Create explicit sections to intercept drillholes, digitize the layer of interest to form a wireframe or geological domain, and configure northing‑based quick plains from -600 to 400 at 100‑unit intervals.

Create geological cross sections by displaying drill holes, correlating lithologies with strings, and using sections as the base for a geological model.

Create cross sections from prepared sections and digitize drill holes to build geological cross sections, then separate ore and waste into wireframes and clean strings by filtering points.

Create and validate 3d solid models from lithological segments by triangulating between segments, extruding for drill-hole influence, and converting to solid objects in Surpac.

Perform drillhole compositing to standardize variable samples to a one meter length, weighting grades per meter for geostatistical estimation in Surpac, preparing data for block modeling and resource estimation.

Learn to generate basic statistics in Subpack by loading a composite string file, creating a histogram, viewing probability and normal distribution curves, and exporting a CSV report.

Create a block model by discretizing ore into cubes, assigning grade and density, and interpolating values for accuracy. Set block sizes and sub-blocks, define extents, rotate, then save and view.

Add block model attributes (fe, se o2, al2o3, and a proportion percentage) with negative background values and two-decimal real numbers, then interpolate and proceed to resource estimation.

Create and apply a constraint file to limit the block model to the ore body, using a 3d solid model, topography, and water level planes for accurate estimation.

Create a constrained block model with interpolated attributes using inverse distance estimation and generate a pdf resource report with volume adjustment, density, and elevation-based grade ranges.
