post_samples
The post_samples module is used to visualize:
- Sampling locations and the values of the properties in .apdv files
- The lithology specified in a .pgf, .lsdv, .lpdv or .geo files
- The location and values of well screens in a .aidv file
Warning
When using the Datamap parameters (Minimum and Maximum) unlinked such the the resulting datamap is a subset of the true data range, probing in C Tech Web Scenes will only be able to report values within the truncated data range. Values outside that limited range will display the nearest value within the truncated range.
Along with a representation of the borings from which the samples/data were collected. The post_samples module has the capability to process property values to make the posted data values consistent with data used in kriging modules. Data can be represented as spheres or any user specified glyph. The sampling locations may be colored and sized according to the magnitude of the property value, and labels can be applied to the sampling locations with several different options.
Each sampling location can probed for data by holding the Ctrl button and left-clicking on the sample location.
When you read any of the supported file types, the module automatically selects the proper default settings to display that data type. However, some file formats can benefit from different options depending on your desires and the quantity of data present.
Below is the Properties window for post samples after reading a .PGF file. Note that “Samples” and “Screens” are selected.
The result in the viewer is below.
If we turn on Well Labels and Sample Labels (with some subsetting to declutter), the viewer shows:
The post_samples module can also represent downhole geophysical logs or Cone Penetration Test (CPT) logs with tubes which are colored and/or sized according to the magnitude of the data. It can display nonvertical borings and data values collected along their length, and can also explode borings and sample locations to show their correct position within exploded geologic layering.
When used to read geology files, post_samples will place surface indicators at the top (ground) surface and the bottom of each geologic layer that are colored according to the layer they depict. When a geology file (.geo or .gmf) is exploded without using geologic surface input from gridding and horizons there will be surface indicators at the top and bottom of each layer. You may color the borings by lithology.
Module Input Ports
- Z Scale [Number] Accepts Z Scale (vertical exaggeration) from other modules
- Explode [Number] Accepts the Explode distance from other modules
- Date [Number] Accepts a date to interpolate time domain data
- Input Geologic Field [Field] Accepts a data field from gridding and horizons to krige data into geologic layers.
- Subsetting Feature [Field] Accepts a (1D) line or (2D) surface to be used to subset the borings.
- Sample Glyph [Field] Allows the user to import a field containing a geometric object which will be the glyph displayed at each sample location.
- Filename [String / minor] Allows the sharing of file names between similar modules.
Module Output Ports
- Z Scale [Number] Outputs Z Scale (vertical exaggeration) to other modules
- Explode [Number] Outputs the Explode distance to other modules
- Geologic legend Information [Geology legend] Supplies the geologic material information for the legend module.
- Boring Tubes [Field / minor] Outputs the tube paths as lines with data
- Boring Data [Field / minor] Outputs the tube paths as lines with data
- Filename [String / minor] Allows the sharing of file names between similar modules.
- Analytes Name [String / minor] Outputs a string containing the name of the currently selected analyte or date
- Sample Data [Renderable]: Outputs to the viewer
Properties and Parameters
The Properties window is arranged in the following groups of parameters:
- Properties:
- selected data component
- Z Scale (remember this should be set on the Home tab or Application properties)
- Display Toggles: including screens, borings, well and/or sample labeling, etc.
- Sample Settings: controls clipping, processing (Log) and clamping of data.
- Collapse to 2D: controls how 3D data is subset to 2D
- Geology Settings: controls the display of geologic data
- Time Settings: controls how the module deals with time domain data
- Boring Tube Settings: controls how borings are displayed
- Color Tube Settings: controls the display of colored tubes as an alternative representation (vs. spheres or glyphs)
- Label Settings: parameters association with labeling of borings and samples
- Remember that toggles to turn on labels for Wells or Samples are at the top in Properties.
- There are type-ins which receive Python expressions providing a great deal of power to adjust how you label wells and samples
- Default expressions (which vary by file type) are automatically created for you (when these are Linked) to make the labeling more logical.
