SurView internal tools
The following tools are accessible from SurView's Tools menu.
Note that most of them are disabled in the free runtime version of SurView.
All of the tools are enabled in the full version.
Some of the import tools can be activated by dropping a file onto
a running copy of SurView. Note that you can not drop a file to
be imported onto a SurView icon because that requires a File Association
for Windows to activate SurView to accept the file. However, a running
copy of SurView will know what to do with the file.
- Compiler: AOB/ALC -> BOB/BLC
Although there is no tool to create AOB/ALC text files of polygons, polylines,
points & text labels these files can be created using any text editor
using the documentation in SurView's .HLP file. The resulting AOB files
can be compiled to their proprietary binary BOB/BLC forms for
subsequent display in SurView.
This tool can be activated by dropping an AOB/ALC file onto a running copy of SurView.
- Compiler: LXF -> SLD
Similarly, there is no tool for creating LXF text files containing multivariable
survey line data, but the format is fully documented in SurView's
.HLP file. The resulting LXF text files are then compiled to a proprietary
binary SLD file for subsequent display in SurView.
This tool can be activated by dropping an LXF file onto a running copy of SurView.
- Create theme for .SHP
SurView has a tool to create a legend theme for a .SHP file
containing polylines or polygons (but not points). The display field
can be selected and colours assigned to the list of unique elements
in that field.
This tool can be activated by dropping a SHP file onto a running copy of SurView.
- DXF import
SurView has a relatively simple tool for importing polyline data from DXF files.
This tool has limited capabilities: the user must recognize that DXF
files are inherently limited in their capabilities to represent closed
polygons in a proper topological structure. In addition, the usefulness
of a DXF file depends primarily on who created it and how it was created.
Most of the problems are caused by the casual and sometimes improper use
of AutoCAD to attempt to digitize topological data.
This tool can be activated by dropping an DXF file onto a running copy of SurView.
- DBF import
Point data (structural or 'geochemistry') can be imported from
.DBF files, to create proprietary binary .BOB files for display in
SurView.
This tool can be activated by dropping a DBF file onto a running copy of SurView.
- Enter point/line/polygon data
SurView has a simple digitizing tool that allows points to be
entered interactively by clicking on the display. The points
can be isolated, joined in a polyline or joined in a polygon.
The data is written to a proprietary .AOB text file, which is
then compiled with SurView's AOB compiler to create the binary
.BOB file for display in SurView.
- Register grid image
Any grid file can be geo-registered by selecting known
points and entering the known co-ordinates. This is mostly used
registering .BMP or .RAS images for which .GRX files have been
prepared with the external HDR2GRX.BAS utility (see below).
- Export SLD
SurView can export multivariable survey line data from
an SLD file to (large) XYZ text files in Geosoft or Geopak format.
The same tool can also create Arc/Info .AML files to create line
and point coverages of flight lines, flight line labels, flight
line tick marks and flight line tick labels.
- Export stacked profile from SLD
While viewing a stacked profile section of multivariable airborne survey
data, SurView can export the data in a format suitable for use in any
spreadsheet application ('comma and quote-delimited text file').
Grid/point correlation
SurView can take a table of point locations and look up the corresponding
grid values from any grid/image that has been set up for display in
SurView. The results are written to a text file that can be
imported into any spreadsheet application for subsequent analysis.
- Intersect .SLD file with .BOB file
SurView can intersect an .SLD file (Survey Line Data) file of
flight lines with a .BOB file containing polylines and/or
polygons. This allows SurView to display the polylines and/or
polygons in the stacked profile cross-section display for any
selected flight line.
