The Earth Science Software













The Geoblock program is integrated software for 2D/3D modeling, computational geometry and visualization of spatial datasets. The program can be used in Earth sciences particularly in such fields as survey, geology and mining modeling, ore reserve estimations and prediction of mineral liberation under grinding and mineral processing operations.


The program supports several spatial dataset types for scientific computation and modelling:  Points, Drill-holes or Boreholes, Polygons, TIN (Triangulated Irregular Network), Solids, Grids and Meshes. 

The generation of grids and meshs in 2D/3D is implemented. Routines for exploration and processing drillhole data include: statistical data analysis and data transformations; compositing drillhole samples inside benches and grade intervals; calculation coordinates of samples along drillholes and exploration lines; prediction of mineral liberation phenomena in grinding operations and ore dressing parameters, simulation of mining processes in pits and shafts,  etc.

Interpolation methods: Inverse Distance, Linear, Closest Point, Kriging, Natural Neighbors and Polynomial Regression.

Constructed grids and block models could be used for open pit optimization and mine planning. Deposit reserves for any ore type or sort can be calculated with different methods using spatial computer models.


Combined datasets can be organized into Model collections and displayed inside Map Window of the program as a combination of contours, wireframe or block models simultaneously.

Several spatial models could be visualized simultaneously in GeoScene window of the program using Project Manager as shown in the next figures:

The databases can be represented in various relational formats: Paradox, Interbase, MS Access and Oracle. You may export/import spatial data and graphical objects in DXF (AutoCAD), MIF/MID (MapInfo), GRD (Surfer, ArcInfo) and other formats.

Tools & Libraries

Development Environment:

The Geoblock software is written in Borland Delphi for Windows 2000/XP. You may download freeware Delphi Personal Edition version from Borland site.

Included libraries and components:

GLScene, Jedi Codes, Graphics32,

GSLib Geostatistical Library,

VirtualTreeView - the treeview control

Necessary software tools:

TortoiseCVS, Code Formater,

MS HTML WorkShop


GNU Gettext - GNU gettext for Delphi

poEdit the tool to edit translations


You can download new releases from Files page or get the whole latest archive (~10Mb) from Nightly CVS Tree Tarball.

To change the natural language of user interface, please, go to Configuration dialog and set your choice in the combo box list. English and Russian localizations only available now.

Note: The most features of the program work only with Borland Database Engine (BDE), which could be found on Borland Delphi or Geoblock installation disks as deployable components.


You could help the Geoblock project development as a programmer, code donator, document writer, as a partner or distributor. If you have any proposals and questions about the program, please, send your request to mailing lists or main administrator of the project:
