Summary of Utility PIEs

NAME
       Utility PIEs - Programs for Simplifying the Analysis of Geographic Information in 
          U.S. Geological Survey Ground-Water Models for use within Argus Open 
          Numerical Environments (Argus ONE)

ABSTRACT

This report describes a number of programs developed at the U.S. Geological Survey (USGS) to enhance existing USGS graphical user-interfaces for ground-water modeling programs. The programs are in the form of dynamic-link libraries that add interpolation methods, commands, and functions to Argus ONE TM through the use of Plug-In Extensions (PIEs). The interpolation methods, commands, and functions are not specific to any particular type of model but instead may find application under a variety of circumstances. The new interpolation methods provide results much more quickly than the existing interpolation methods in Argus ONE while still giving reasonable results. Some of them also incorporate anisotropy. This may be particularly valuable for cross sectional models. The commands are useful for copying, editing, converting, or importing information. They include commands for creating or modifying grids, editing the precise locations of nodes along contours, importing data as either contours or data points, setting the expressions for multiple parameters, and importing Digital Elevation Models (DEMs). The functions provide convenient methods for evaluating, converting, or storing information. Many of the functions are hidden because they could cause memory leaks if used improperly or provide specialized functions not likely to be of interest to most users. Nevertheless, these functions provide a convenient method of performing Geographic Information System (GIS) functions that would be difficult to do with Argus ONE alone.

HISTORY
Version Date Description
------- -------- ---------------------------------------------------------
1.10.1.0 14/03/06 Fixed bug that could prevent values from being imported
from Shapefiles.

1.10.0.0 13/11/29 Fixed bug that could cause Argus ONE to crash while being
closed.
Improved deletion of multiple points.
Fixed import of ascii rasters if free format is used for
the header.

1.9.0.0 12/08/11 The images on the buttons in the OK_Cancel PIE have been
removed and the font was reduced in size.
Added ability to delete multiple data points in
PIEs|Edit|Edit Data.
In PIEs|Import|Import ASCII Raster data, you can now import
the entire raster.
Fixed bug in Ok_UserFloat in which max and min values were
not set properly.
Added an optional boolean parameter to BL_PointInsideContour
function. If it is set to true, the X and Y coordinates are
changed from the global coordinate system to one parallel
to the grid. If the optional parameter is not specified, no
transformation occurs.

1.8.0.0 12/04/20 Added Triangle Interpolation procedure.

1.7.15.0 11/01/21 Fixed the "PIEs|Import|Sample Data..." command; the last
data point in the file was being skipped.

1.7.14.0 10/11/01 Fixed the sampling data from comma-delimited files when nothing besides the comma was used as a delimiter.

1.7.13.0 09/09/17 Added error message to procedure for importing raster data when
no data points are inside the grid.
Fixed bug importing text fields from Shapefiles
Fixed bug in deleting multiple layers.
Fixed bug in reading shape files

1.7.12.0 08/12/09 The various QT_ interpolation methods now use temporary files
for storing some data to help conserve memory.

1.7.11.0 08/04/02 When imporing Shapefiles, there is now an option to import the
orientation of the shape at each point.

1.7.10.0 07/03/19 Fixed bug in import of ASCII Raster grid data.

1.7.9.0 07/01/11 Converted to using .chm files for help for compatibility
with Windows Vistas.

1.7.8.0 06/09/25 Fixed bug importing Shapefiles containing text attributes.
