Our Flair

Creative amalgamation of simplicity and applied thought.

Geographic Approach

Science seeks to classify the behavior of the world into generalized laws and then apply those universal laws to all things. However, location implies a unique position on the landscape - and land variations impart unique characteristics that defy such scientific generalization. Consequently, the performance and interaction of technology and business process change as a function of landscape and environment. TGI Systems builds tools, methods, and services that:

  • Maximize the benefit of specific locations through the scientific adjustment of engineering systems and business process approaches.
  • Organize and integrate information based upon location and proximity to other entities.
  • Analyze the interactions between systems based upon the separation and/or proximity of system components.

This is a common argument within the discipline of geography where land may be viewed as either idiographic or nomothetic. The prior definition implies a landscape of uniqueness where universal generalizations cannot describe the variation between places. A nomothetic approach states that all things must fit universal laws.

There is little doubt this argument will continue for some time, however, TGI Systems has found that technology has become more flexible than land use. This makes sense because technology has been progressing as rapidly as our cities, governments, and changing information needs.

This leaves local landscape as the external set of constraints, with technology the design variable (not the traditional approach of applying the same technology anywhere!). This understanding provides us with the design constraints to develop tools to understand the conflict between competing environmental, engineering, and socioeconomic systems. From this starting point, TGI Systems applies the tool of proactive optimization where technology is optimized to the environment and socioeconomic system it must function within.

Company History

The central focus of TGI Systems LLC is the integration of information through the use of location. The firm has mathematical roots in technology design based upon the optimization of engineering, environmental, and socio-economic criteria. Company endeavors center on thinking outside-the-box to develop improved business solutions. TGI Systems is the evolutionary result of two prior firms.

  • The first firm was Wyman Real Estate Company running from 1986 through 1997. Here, the importance of location and the distribution of services across the landscape were learned.
  • The second firm, Terra Genesis, was operated from 1997 through 2012, focusing on the use and development of spatial data within relational and geographic information systems.

TGI Systems takes the next step, with a direct focus on enterprise information, location, and process integration.

Project Experience

2020 Gila County Financial Exchange: created a synchronization protocol to shift data between disparate financial and treasury systems in support of warrant clearing, journal entries, and collections.

2018-Present WyPoint: an initiative to create a centralized nation-wide garment care system where any cleaner or private operator can create and operate a garment care pickup and delivery route.

2013-2014 Battery-Switching Station Location Optimization: a two-year mathematical methods project used in the location of electric vehicle battery service stations across Europe.

2009 Navajo County Parcel Completion Project: split or otherwise created 9000 parcels to complete the Navajo County parcel base map. Cleaned topology and attributes. Created and implemented a parcel temporal data model.

2006-Present Navajo County Information System: an on-going enterprise-wide data integration project, currently spanning work management, building permits, highway management, fleet maintenance, treasury, civil law, business permits, medical examiner, birth certificates, e911, flood control, and others.

2002-2006 Texas Department of Transportation GIS Architecture and Infrastructure Project: designed and led the development of a geo-temporal object database for the integration of disparate data across the Texas Department of Transportation. The application approach employed time-stamped graphic data to combine time, location, and data properties into a single record. This data structure facilitates complex queries with simplified and more manageable data structures and query controls.

1999-2000 Hong Kong Transport Information System Conceptual Design: an initiative to integrate the data and processes across three government agencies and a variety of private transport providers. The tools pioneered here form the basis of TGI Systems business methodologies.

1999-2004 Apache County Integrated Information System: designed and developed an integrated information system where data from engineering (roads, sign, and structures), assessor (parcels, ownership, sales, 911 addressing), health (septic, well, restaurant permits), planning (permits, zoning, conditional use), building permits, county functions (voting, vehicles, employees), and 30 different GIS layers, may be viewed and queried from a single internet application.

1999 Texas Department of Transportation Dynamic Location Data Model and Linear Referencing System Design: a revolutionary spatial query process that does not require the use of complex GIS topology was developed for the Texas Department of Transportation. The resulting data form is compact and efficient, offering full temporal version control and a variety of other database benefits previously unavailable to geographic information sciences. In an effort to develop a fully operable transportation network model, specifications were also prepared to re-map Texas roadways by roadbed at sub-meter resolution using Light Detection and Ranging (LIDAR) and decimeter pixel digital ortho-photography. Techniques for joining ramps, modeling stacked roads, and complex transportation features were developed. A new linear referencing system was then developed to exploit this ultra-fine network using GPS. The data model has proven so successful, it has also been adopted by the State of Texas state-wide vertical integration project called the Strategic Mapping Initiative.

1998 GPS bid preparation, Cochise County Highway and Floodplain Department: developed specifications for the purchase of a survey-grade GPS that included a pre-purchase test fitted to the geographic area of Cochise County.

1997-2000 FHWA Local Technology Assistance Program: conducted workshops for highway field staff across Arizona, Nevada, and Idaho on various subjects, to include the Global Positioning System and metric conversion.

1997-1998 City of St. Johns, Arizona: working in conjunction with Arizona State University, a decimeter-grade GPS was employed to map of city sewer and water systems. Attributes were collected and assigned to build an infrastructure management system. Using GPS-collected field monuments, less accurate GIS data layers were shifted and conflated to better reflect field-collected accuracy.

Company Approach

TGI Systems staff employ a variety of innovative approaches when addressing the design or redesign of information, processes, networks, or technologies. These techniques are based on experience and are used to cut through legacy and convention to expose the naked building blocks of the best solution.

Problems typically center on balancing the competition between engineering, environmental, or socioeconomic systems. The solution must be balanced across the dimensions of time, space, and available capital. Resolution is achieved through the optimal mix of people, process, technology, and information to yield the best solution.

Hydrogen Locomotion

Energy, environment, and sustainability are central to facilitating technology and economy in a world of population pressure and depleting energy supplies. TGI Systems staff were some of the first thinkers who suggested replacing the diesel engine of diesel-electric locomotives with hydrogen fuel cells. This makes sense from an engineering perspective because diesel-electric locomotives are already electric, and they typically add power in incremental steps from Stop to Train 8.

However, the true magic of this union is not what hydrogen can do for rail, but what rail can do for the developing hydrogen economy. The current petroleum-based energy economy enjoys an installed economy of scale. We already have hydrocarbon exploration, drilling platforms, refineries, and distribution systems feeding hundreds of thousands of fuel stations built and in use. A hydrogen energy economy must first be established as a competitor to this infrastructure. The anticipated cost is considered to be extreme.

The key here is that locomotives have a range in excess of 500 miles and that rail networks connect major economic hubs. This means very few fueling stations are needed to seed a new energy economy (perhaps fewer than twenty for the United States). And indeed, this particular transportation mode has carried the majority of economic activity for many countries for many years.

The papers and presentations below are a cross section of the work Dr. Wyman, Stephen J. Bespalko, and TGI Systems, Inc. has performed in support of the hydrogen rail initiative. Additional papers are provided which also support the overall hydrogen initiative.

Linear Referencing

From the time of the Romans, linear referencing has been employed to locate assets along linear resources such as road, railroads, and energy distribution networks. Dr. Wyman, together with Stephen J. Bespalko, helped take some of the initial steps to bring linear referencing into the three-dimensional world of global positioning satellite systems. These three-dimensional techniques applied modern GIS constructs such as the measured shape and applied them to the problematic issues of legacy network pathologies.

Cadastral, Financial, and Treasury System Integration

TGI Systems has created a variety of parcel management, levy generation, and treasury collection tools. The company has also linked together disparate enterprise resource planning tools with treasury management systems, synchronizing checks with warrants, journal entries between different journal systems, as well as collection and posting of online payments and optically-read payments. This understanding of cadastral-treasury-finance interconnection has provided opportunity to regenerate property tax bills mid-cycle, improving timely identification of errors in levy allocation.

TGI Systems has constructed tools for the synchronization of ownership between disparate GIS, cadastral, taxation, and e911 data sets. The company has also coordinated digitized data sets for various cities and counties, as well as 475 thousand miles of highways in the State of Texas.

Garment Care

The garment care industry has been undergoing evolution, shifting from dry to wet cleaning, store-front to route-based direct-delivery, and automation of assembly and garment identification. TGI Systems has developed web-based point-of-sale and associated cloud-based information systems, GPS-based routing systems, and barcode identification systems with direct connection to automated assembly systems.

WyPoint, as developed by TGI Systems, is a web-distributed system that maximizes pickup and delivery service for participating local area cleaners. Any number of different cleaners may adopt zip code areas for service with different price lists and promotions. This offers online customers choices and options. WyPoint provides both the payment method and routing system needed to harvest the pickup and deliveries for each requested cleaner.
