The AGG class is used to handle image display on maps. An aggragate contains one or more image layers (LAY) with each layer representing a grid or image file. The AGG will combine all the layers to form one image

The BF class is used to access (or create) Binary files and remove (or destroy) files from use. You can also perform a variety of additional tasks, such as positioning within files, reading from files and writing to files.

The DAT object is used to access data from an variety of data sources using the same access functions. The DAT interface supports data access on a point-by-point, of line-by-line basis. For example, the Run_BIGRID function uses 2 DAT objects - one DAT associated with the input data source, which is read line-by-line, and a second associated with the output grid file output grid file. Use a specific DAT creation method for an associated information source in order to make a DAT as required by a specific processing function. The gridding methods all use DATs.

DATALINK Display object.

DATAMINE functions provide an interface to Datamine Software Limited files. See also GIS.GXH for various other Datamine-specific functions.

The DB class is used to create, open and work with databases and database symbols. Database symbols are objects inside databases, such as lines, channels and blobs

The DBREAD class is used to open and read from databases. Very large lines are split into blocks and served up sequentially to prevent the over-use of virtual memory when channels are read into VVs or VAs. Individual data blocks are limited by default to 1 MB (which is user-alterable). Single lines smaller than the block size are served up whole, one block per line.

The DSEL object is used to select subsets of data from the DATA object

External (plug-in) image methods.

The GEOSTRING class is used to read information stored in Geostring files (*.geosoft_string). Geosoft geostrings are 3D vector files that store digitized interpretations drawn on section maps. Both polygon and polyline features can be stored in the same file. This API currently only provides read access, but read/write support could be added in the future.

The GIS class is used for the import, export, and interrogation of GIS Data stored in external formats, such as MapInfo® TAB files.

Marks this function as callable from Oasis Montaj.

High Performance Grid. Designed to place grid data on a DAP server. It produces a multi-resolution compressed object that supports multi-threading and allows for high-speed extraction of data at any resolution.

High Performance Data Point Storage. This is used to put Point data on a DAP server. It is compressed and uses a Quad-Tree design to allow very high speed data extraction. It is also multi-threaded.

International Geomagnetic Reference Field Methods to work with IGRF objects. The IGRF object contains data for the IGRF model of the geomagnetic reference field.

The IMG class performs read and write operations on grid file data. When efficient access along both rows and columns is desired the PG class is recommended (see PG and PGU); the IMG is first created, then the PG is obtained from the IMG using GetPG_IMG.

Not a class. This is a catch-all group of functions working on IMG objects (see IMG). Grid operations include masking, trending, windowing, expanding and grid stitching.

The IPJ class describes a single spatial reference in the world, defined under a coordinate system, an orientation, and a warp (which can be used to distort the projected object to a particular shape or boundary).

The ITR class provides access to ITR files. An ITR file maps ranges of values to specific colours. The ITR object is typically used in conjunction with MVIEW objects (see MVIEW and MVU).

Layout class for generic relative layout calculation The relative layout algorithm allows a logical organization of layout rectangles. You can set constraints with English-like semantics. For example: "Set the left side of rectangle 1 equal to the right side of rectangle 2 plus 10 pixels." "Set the bottom of rectangle 1 to 25 percent of the height of rectangle 2." "Move node 1 such that its bottom is equal to the top of rectangle 2 minus 10 pixels." The last constraint set would enjoy priority over any others as it would be the last one that would influence the rectangle calculations. See the notes for iSetConstraint for more details.

local datum lookup creator ll2 methods are used to create LL2 objects. LL2 objects contain latitude, longitude correction lookup tables to convert between datums.

This class allows access to the current default line patterns. It does not allow the definition of individual patterns. It is is used primarily with MAP class functions.

The LST class is used to create and retrieve lists, and to perform specific actions on lists, including retrieving list items, sorting lists and adding or removing list items.

An LTB object is typically created from a CSV (comma-separated values) file, and is a table of information that may be accessed by row or column. The LTB class is recommended for use with small tables produced from short lists (of the order of 1000's or records) such as the different geographic projections and their defining parameters. Large tables, such as those required for table-lookup functions, should be accessed using the TB class.

MAPs are containers for MVIEW objects. A view is a 3-D translation and a clip window on a map. Graphic entities can be drawn in an MVIEW. It is recommended that the MAP class be instantiated by first creating an EMAP object and calling the Lock_EMAP() function. (See the explanation on the distinction between the MAP and EMAP classes).

The MAPL class is the interface with the MAPPLOT program, which reads a MAPPLOT control file and plots graphical entities to a map. The MAPL object is created for a given control file, then passed to the MAPPLOT program, along with the target MAP object on which to do the drawing

A MAPTEMPLATE wraps and provides manipulation and usage for the XML content in map template files. See the annotated schema file maptemplate.xsd in the <GEOSOFT>\maptemplate folder and the accompanying documentation in that folder for documentation on the file format.

This is not a class. This is a collection of standard mathematical functions, including most of the common logarithmic and geometric functions.

A META object contains hierarchical organized metadata of any type, including other objects. META information is organized in an XML-like structure based on a data schema that describes the data hierarchy. META objects are used by many entities that need to store metadata specific to the entities or to the application. Metadata can be saved in databases and maps, as well as in channels, lines, views and groups. Oasis montaj objects can be queried for their associated metadata, and if it exists, the metadata can be retrieved and utilized by other Oasis montaj processes.

A view (MVIEW class) has a 2-D/3-D translation matrix, a map projection and a clip region. A view contains any number of "groups", and each "group" contains one or more graphics elements (entities). Different types of groups will contain different types of entities:

A catchall library for methods using the MAP and MVIEW classes. These include drawing flight paths, legends, postings, and special objects such as histograms and bar charts.

A MXD wraps and provides manipulation and usage for the content of an ArcGIS MXD file.

A PAT object is created from a Geosoft-format pattern file. It contains all the individual patterns listed in the file. Notes You may create your own fill patterns should be added to the "user.pat" le in the <geosoft>\user\etc directory. you wish to add your own fill patterns, create a file named user.pat in e <geosoft>/User/ directory and add your own fill patterns in the number nge 20000 to 29999.

Pager methods for large 2-D arrays This class handles very-large 2-D arrays in which efficient access is required along both rows and columns.

The PJ object is created from two IPJ objects, and is used for converting data in an OASIS database or map object from one map coordinate (projection) system to another.

The PLY object contains the definitions for one or more polygons, and does import and export of polygon files.

The RA class is used to access ASCII files sequentially or by line number. The files are opened in read-only mode, so no write operations are defined

default summary

The REG class is used for storing and retrieving named variables. Many classes contain REG objects for storing information particular to the class. The META class supersedes the REG class and is gradually replacing the use of the REG class in newer applications.

The SBF class provides a means of storing data in a file-type directory structure within a workspace, database or map. Each of these three objects contains its own SBF object, which may be accessed using the hGetSYS_SBF, hGetDB_SBF and hGetMAP_SBF functions. To access data in a file, or create a new file in the SBF object, call the CreatSBF_BF function (see BF), which will return a BF object to use.

Mono-variate statistics. The ST class is used to accumulate statistical information about a set of data. This class is usually used in conjunction with others. For instance, Stat_DU (see DU) will add a channel's data to the ST object, and sComputeST_IMG (see IMG) will compute statistics for a grid.

Bi-variate statistics. The ST2 class accumulates statistics on two data vectors simultaneously in order to compute correlation information. Statistics are accumulated using the DataVV_ST2 function. See also ST (mono-variate statistics).

This library is not a class. Use the STR library functions to work with and manipulate string variables. Since the GX Programming Language does not provide string literal tokens, you must use these functions for any string operations you want to perform.

The SURFACE class allows you to create, read and alter Geosurface files (*.geosoft_surface). A Geosurface file can contain one or more surface items (see SURFACEITEM class). In turn each item can contains one or more triangular polyhedral meshes.

The SURFACEITEM allows you to create, read and alter Geosurface files (*.geosoft_surface). A Geosurface file can contain one or more surface items (see SURFACE class). A surface item can contains one or more triangular polyhedral meshes.

The SYS library functions perform a wide range functions, including the storage and retrieval of named parameters from the current workspace; writing messages to the user; display of progress bars; retrieving file, date and time information from the operating system; and providing warning and error handling functions.

The TB class is a high-performance table class used to perform table-based processing, such as leveling data in an OASIS database. The LTB class is recommended for use with small tables produced from short lists such as the different geographic projections and their defining parameters.

The full name of the pattern. ex: "felsic volcanics" Code: Short-form of the pattern description. This is the value which typically appears (for instance) in the "Rock code" channel in a Wholeplot From-To data group. ex: "FVOL" The code is CASE-SENSITIVE. Label: Text to use as a short-form in labels, graphs etc. By default, this is the same as the code. ex: "FVol." Pattern Attributes: (See DEFAULT.PAT in \src\etc for more inforation) Pattern: The Pattern Index; defined in DEFAULT.PAT, or in the user's USER.PAT file. If not specified, defaults to 0 (solid fill). Size: The pattern tile size. If not specified, defaults to 2.0mm. Density: The tiling density. If not specified, defaults to 1.0. Thickness: The line thickness in the tile, expressed as a integer percentage (0-100) of the tile size. Colour: The pattern line work colour. If not specified, defaults to black. Background colour: The pattern background colour. If not specified, defaults to transparent (C_ANY_NONE) Symbols: Symbol Font The name of the symbol font to use for a given symbol index Symbol Number Index into the font. Symbol Rotation: Rotation in degrees CCW. Symbol Scaling Additional scale factor to apply to symbol size (Default 1.0)

The TR object contains trend information about a grid or grid pager. Currently, it is used only in conjunction with the GetTR_IMG, SetTR_IMG, and Trend_PGU functions.

The USERMETA class handles user style metadata tied to real data.

The VA class is the 2-Dimensional analogue to the VV class. When displayed in a database, VA objects are displayed graphically as profiles, one to a cell, and can also be displayed one column of data at a time by specifying an index; e.g. CH[0]. A VA object is declared with a fixed number of columns, which cannot be altered. The number of rows, however can be changed, in the same way that the length of a VV can be changed. Data can be added or extracted using VVs, either by row or column. A VA is used to store an array of data in which each element may have multiple elements. For example, 256-channel radiometric data can be stored in a VA that is 256 elements wide.

In-memory vector data methods The VM class will store vector (array) data in a memory buffer which can be accessed using the VM methods. The main use for the VM class is to store data in a single physical memory location. This memory can then be accessed by a user DLL using the GetPtrVM_GEO function defined in gx_extern.h. VM memory can be any size, but a VM is intended for handling relatively small sets of data compared to a VV, which can work efficiently with very large volumes of data. The acceptable maximum VM size depends on the operating system and the performance requirements of an application. The best performance is achieved when all VM memory can be stored comfortably within the the available system RAM. If all VM memory will not fit in the system RAM, the operating system virtual memory manager will be used to swap memory to the operations systems virtual memory paging file. Note that the operating system virtual memory manager is much slower than the manager used by Geosoft when working with very large arrays in a VV. See VV for methods to move data between a VM and a VV.

High Performance 3D Grid. Designed for accessing 3D grids quickly using slices. It designed arround non-uniform multi-resolution compressed storage. o sample a voxel at specific locations, use the VOXE class.

VOX Display object.

VOX evaluator class. Used to sample values from the voxel.

The VULCAN class is used for importing Maptek® Vulcan block and triangulation files.

The VV class stores very long vector (array) data (such as channel data from an OASIS database) in memory and performs specific actions on the data. This set of functions is similar to the VM functions except that you cannot access data directly and therefore you cannot use a VV to pass data to an external (non-Geosoft) Dynamic Link Library (DLL) object function. If you want to pass data to a DLL, you must move a subset of the data stored in memory to a small vector object and then use the GetPtrVM_GEO function to pass a pointer to the data on to the external function. See VVU for more utility methods.

The WA class enables you to access and write data to ASCII files.
