License and Tech Requirements

Email | Print | More


Standard GMMS licensing permits use of the data at a single (or optionally, at multiple) GIS end-user workstations, and distribution of maps created on licensed workstations in either print or electronic form with only minor attribution requirements. See the standard License Agreement (in PDF format) for details. Custom licensing for large GIS sites, multi-user map servers, or other situations not covered by the standard license can be negotiated on a case-by-case basis.


System Requirements

GMMS 2017, which uses ArcGIS Desktop 10.4 or 10.5

  • This utility,, will show you if the ArcGIS Desktop software will run on your computer.
  • 2.2 GHz, Intel Pentium 4 or above or equivalent AMD CPU with SSE2, multi-processor or multi-core recommended; most processors shipped in full-powered laptops and desktops since roughly 2008 meet these specifications.  Low-power processors (Intel Atom, etc) used in netbooks and tablets often do not have necessary power and features and have not been tested; if you wish to try installing on a such a device, contact GMI technical support for a temporary ArcGIS license in order to test.
  • Windows 7, Windows 8.1, Window 10 current service packs. For Macintosh computers, see ( Note that some GMMS users have had success following these instructions and some have found they didn’t work (i.e. the ArcGIS Desktop software ran slow).
  • 4 GB minimum computer memory, 8 is recommended for improved performance
  • OpenGL 2.0 or higher compliant video card is required, with at least 64 MB of video memory, however 256 MB of video memory or higher recommended, 24 bit capable graphics accelerator. NVIDIA, ATI, and Intel chipsets supported.
  • DVD-ROM drive
  • 10 - 37 GB free disk space on a single drive, preferably on drive C. Maintaining 20% free space on the drive after installation is strongly recommended for best performance. Software and standard GMMS data collections require 6 GB. The included Data and Maps for ArcGIS data collection includes approximately 28 GB of additional data; however, this can be installed selectively as needed. An additional 1.9 GB of space is required for the optional Populated Place Data Supplement, if purchased.

ArcGIS Extensions

Extensions add functionality to ArcGIS for Desktop, the GIS engine of the Global Ministry Mapping System. GMMS users may order these extensions through GMI at appreciably reduced cost. A free 30-day evaluation of any extension can be activated within ArcGIS for Desktop; GMMS users are encouraged to discuss potentially needed extensions with GMI and to take advantage of the evaluation period before purchasing.

ArcGIS Spatial Analyst

Advanced GIS Spatial Analysis Using Raster and Vector Data

ArcGIS Spatial Analyst provides a broad range of powerful spatial modeling and analysis features. You can create, query, map, and analyze cell-based raster data; perform integrated raster/vector analysis; derive new information from existing data; query information across multiple data layers; and fully integrate cell-based raster data with traditional vector data sources.

ArcGIS 3D Analyst

Three-Dimensional Visualization, Topographic Analysis, and Surface Creation

ArcGIS 3D Analyst enables you to effectively visualize and analyze surface data. Using ArcGIS 3D Analyst, you can view a surface from multiple viewpoints, query a surface, determine what is visible from a chosen location on a surface, and create a realistic perspective image draping raster and vector data over a surface. ArcGIS 3D Analyst also allows your traditional GIS data to be viewed, analyzed, and verified in 3D without having to create additional data.

The ArcGlobe application in ArcGIS 3D Analyst allows you to manage and visualize, from a local or global perspective, extremely large sets of three-dimensional geographic data. ArcGlobe provides the capability to seamlessly interact with any geographic information as data layers on a three-dimensional globe.

ArcGIS Publisher

Share Your Maps With Others

ArcGIS Publisher enables the creation of a published map file (.pmf) format for any ArcMap document. PMFs are used in the free ArcReader application and allow you to share your ArcMap documents with any number of users. The PMF format can also be used to deploy your map over the Web or Intranet through the ArcGIS Server.

ArcScan for ArcGIS

Raster to Vector converter

ArcScan for ArcGIS provides a comprehensive, efficient, and easy-to-use set of tools for raster-to-vector conversion.


ArcGIS Geostatistical Analyst

Statistical Tools for Data Exploration, Modeling, and Advanced Surface Generation

ArcGIS Geostatistical Analyst provides a powerful suite of tools for spatial data exploration and optimal surface generation using sophisticated statistical methods. Through a series of easy-to-use wizards and dialogs, ArcGIS Geostatistical Analyst allows you to create a surface from a set of data measurements when collecting information for every possible location would be impractical. Whether improving estimation of temperature values, assessing environmental risks, or predicting the existence of any geophysical element, ArcGIS Geostatistical Analyst gives anyone with spatial data the ability to investigate, visualize, and create optimal surfaces.
