GeoLab's main features are as follows:

• Performs least squares adjustments and simulations (pre-analyses) of geodetic and surveying networks and traverses.

• Handles a comprehensive list of geodetic and surveying measurements (GPS, GPS RTK, conventional traversing, trigonometric and spirit leveling, and even processed inertial surveying data), with no limits on the number of measurements that can be processed.

• Used (and proven reliable) world-wide since 1985 in all sizes of companies, many government and defense agencies, and many educational institutions.

• Technical support is very responsive and dependable.

• Imports measurement and coordinate data from many types of GPS receivers, total station instruments, and levels, and if we don't have an import filter for your favorite data, let us know and we'll develop one!

• Imports all older GeoLab IOB format files.

• Handles any combination of GPS, conventional, and leveling data.

• GeoLab's Adjustment Results Summary feature makes it easy to locate large residuals and station confidence regions in your adjustment.

• Supports separate drawing scales for the network itself, overlays and residuals, horizontal error ellipses, and vertical error bars.

• Produces station and relative confidence regions in 1D, 2D, and/or 3D.

• GeoLab is extremely configurable and versatile, making it useful for a wide variety of project types.

• Provides comprehensive statistical analysis tools for easily analyzing networks and traverses of any size.

• Built-in data editing tools, including GeoLab's Record Editor, make data entry and editing easy.

• Supports the specification of centering errors for instrument and target stations.

• Provides powerful tools for incorporating geoids into your adjustments and simulations.

• Handles "weighted station" adjustments rigorously.

• GeoLab's companion "Explorer" application provides access to GeoLab's binary adjustment files so that you can use these data easily in your own in-house applications.

• GeoLab's overlay network capability helps with deformation and control closure analyses.

• Provides versatile and comprehensive coordinate transformation tools.

• Uses rigorous (no approximations) mathematical models that can handle 1D, 2D, and 3D networks.

• Handles adjustments in global 3D coordinate systems as well as local x, y plane coordinate systems.

• Provides tools for analyzing coordinate differences between different measurements of deformations surveys.

• Provides an extensive help system.

• Models several types of scale, translations, and constant parameters right in the adjustment or simulation.

• An open design allowing the development of your own in-house applications and data import filters.

• Provides a powerful tool for easily renaming stations in an adjustment from "field names" to actual station names.

• Supports the development of third-party data import plug-ins.

• GeoLab provides a "Station Data Calculator" which can be used to calculate "observed" or geodetic inter-station measurements (local and geocentric), and to calculate station coordinates from measurements (handles both direct and inverse computations).

• Handles many different linear unit definitions, with the capability of creating your own definitions.

• GeoLab's powerful Coordinate Transformer performs many different types of coordinate transformations.

• Performs and solves for datum transformations.

• Handles many different reference ellipsoid and datum definitions, with the capability of creating your own definitions.

• Fast throughput for even very large networks.

• Uses a fast station reordering algorithm to improve throughput for very large networks.

• Thorough checking of input measurement and coordinate data for errors.

• Accepts and correctly adjusts any combination of vertical, horizontal, and 3D networks of measurements.

• Accepts GPS accuracy information as covariance, correlation, or weight matrices.

• Processes vector, session, and RTK GPS data.

• Efficiently computes all residual standard deviations for a more realistic statistical analysis.

• Plots histograms and network drawings with many options for configuring the drawings to your specific needs.

• Automatic initial coordinate generation.

• Adjusted coordinate listings can be used directly in GeoLab's Coordinate Transformer.

• Fast geoid model interpolation using either bi-linear, bi-quadratic, bi-cubic, or bi-quartic interpolation.

• GeoLab's Geoid Manager provides a Geoid Viewer which can use to manually interpolate geoid models for undulations and deflections of the vertical with respect to any datum and in any linear unit.

• Supports angular measurement types in either degrees, minutes, and seconds, or in grads (gons).

• GeoLab can handle virtually any geoid model though the use of special geoid specification (GSP) files which you can create yourself using GeoLab's Geoid Manager.

• Supports local geoid improvement by adding the effect of your own geoid undulation determinations with, for example, GPS on leveling benchmarks.

• Supports multiple geoid models in an adjustment or simulation.

• Handles many different map projection definitions, with the capability of creating your own definitions.

• Performs automatic "zone jumping" when multiple map projection "zones" are used in your adjustments.

• Provides memory configuration tools so that you can get the best performance with your particular computer.

• Produces adjusted coordinates in virtually any coordinate system you choose.

• Windows 98/ME/NT/2000/XP or later supported.

• Handles heights of instruments and targets, with automatic reduction of measurements to the station markers.

• And much more!

Microsearch GeoLab Improvements
We have put a lot of work into improving the new release of GeoLab. A thorough revision of many of the core components of GeoLab has been made, resulting in a more robust and dependable program. All known bugs have been eliminated, and, in addition to the core component revisions, many significant improvements have been made including the following:

• The hardware key is gone! It has been replaced by a very friendly licensing system that is fully Internet friendly!.

• Microsearch GeoLab can now import foreign-format data files directly. Both GPS and conventional (e.g. total station) data file formats are supported, and third-party developers can develop their own plug-in modules that GeoLab will automatically recognize and load at startup. All loaded formats are displayed using the File/Imports menu.

• Network drawing efficiency has been increased dramatically (with immediate scrolling response, for example), and you can now export network drawings to bitmap or Windows metafile formats as well as the usual DXF format.

• The GeoLab Preferences dialog has been significantly expanded. A new option to specify the Windows execution priority for GeoLab has been added, which can improve processing speed significantly.

• GeoLab now supports network adjustments in local x, y coordinates (XY records).

• GeoLab's Geoid Manager interface has been substantially improved.

• GeoLab's Options dialog has been improved, now providing an "Apply" button so you can see the effects of options changes without closing the dialog, and new options were added to support the new features in GeoLab.

• Station reordering is much more efficient now, and results in more efficient processing of large networks.

• GeoLab's toolbar is now more configurable, as well as more complete.

• Context help is much improved throughout Microsearch GeoLab 2001, and you will appreciate the new Help on the Web feature!

• Text files can now be opened in read-only mode, and text and network windows now have a more complete and useful context menu (right-click popup menus).

• GeoLab has a new and improved network drawing print-preview feature.

• The output of data in the User-Defined Station Data Lister dialog is more configurable now with the addition of a feature to specify numbers of decimal places in the output.

• An option was added to the Coordinate Observation Extraction dialog to output XYZ records and the corresponding covariance matrix in the CT system.

• A configurable "block size" for the main network adjustment and for coordinate and coordinate difference observations which will result in significant speed improvements for large networks.

• "Updates on the web" will optionally notify you periodically of any free updates, as well as major upgrades, for your installation of Microsearch GeoLab.

• The ability to move network window files, including the network drawing, from computer to computer.

In addition, as with all large software packages, various bugs were eliminated in this new release of GeoLab 2001.

Microsearch GeoLab System Requirements
