MidTex Mapping Services Company Profile

MidTex Mapping Services Co. was established in October 1991 to provide high-quality cartographic data and software to Geologists, Geophysicists, and other Engineers. All of our programs, custom programming services, and custom mapping services include professional work ethics, confidentiality, and years of consulting experience.

Programming Services:

MidTex Mapping Services has experience of one who has worked as a programmer in the Geophysical Survey, Piping, and Mapping fields since Oct. 1991. Since that time we have worked on a diverse set of software problems that has served to enhance our abilities at tackling new ones. A sampling of the experience that we have and software that we have written is provided below.

Programming/Design Experience

  • Custom Software:

    • Data Workbench (Electro-Seise, Inc.) - Graphics and x-y data manipulation software written for a geophysical survey company who had proprietary data and specific requirements as to how this data was to be processed, interpreted, and represented. Some of the more notable features of this software include:
      • Custom routines to produce HPGL output for plotting and presentation
      • Custom algorithms applied to the data
      • Multiple sets of data stored into one profile
      • Graphics routines that allow ease of visual processing of the data:
        • Stretch, pan, and zoom the data individually, or bind up to five sets together to track different data representations over the same real-earth profile
        • Append custom information to the datasets, attached to precise locations on the curve
        • Tag specific curves for volumetric analysis and contouring
        • Assign fault locations to be indicated on a map
      • Export utilities written to build files for importing into AutoCAD Map 2.0
      • Custom help system
    • Airborne Data Acquisition System (Electro-Seise, Inc.) - Real-Time Data Acquisition System written for Airborne Geophysical data collection. The application is written in such a way that the operator can concentrate more on the quality of the data being acquired than on the steps needed to acquire it. This ensures higher quality data when the job is done. Notable features include:
      • Simultaneous acquisition recorded from two sources: The first is a frequency counter attached to a sensor that returns digital frequency values, the second is a high-speed GPS unit used to begin and end acquisition as well as to track the location of the aircraft along the profile.
      • Graphical data representation at the end of each acquisition cycle that the operator can OK or discard
      • Timer routines that ensure a specific sample rate
      • Automatic file naming based off of the current profile reported from the GPS unit
    • Texas RRC Conversion Utility (MidTex) - Converts Texas RRC base maps into AutoCAD scripts for import into AutoCAD

  • Commercial Software

    • DEM Import Utility (GeoPak, Inc.) - Wrote a DEM import routine that is being used in their terrain modeling package.
      • Native classes used to read DEM profiles
      • Conversion to text x,y,z format
      • Allows for Datum, grid, and distance units conversion (NAD27/NAD83, Lat-Long/UTM/State Plane, Feet/Meters)
    • MidTex Mapping Services DLG Reader for AutoCAD - Version 1.0 is written as an AutoCAD ADS application for R12, Versions 2.0 and 2.1 are written as ARX applications for R14. The DLG Reader allows users to take advantage of free mapping data that is on the internet by importing it directly into AutoCAD's drawing database. Features include:
      • Create custom base maps from 1:100K scale DLGs (freely available over the internet), or purchase 1:24000 scale (7.5' quad sheet) DLGs from the USGS
      • Convert DLGs from their internal coordinate format into the popular coordinate systems: NAD27/NAD83, UTM/State Plane, and feet/meters
      • Easy to use interface makes it a snap to pull data into a new or existing drawing. Coordinate conversion is straight-forward
      • Import DLGs as single files, or as selected files in a subdirectory. This makes it easy to pull in multiple layers as well as multiple quads
      • On-line help system
      • Import names from the Global Names Information System (GNIS) databases, which are also available over the Internet
      • Contour lines are drawn at proper elevations
      • Fully configurable layering schemes
      • Multiple layering schemes can be maintained easily
      • Single, double, and "fat double-line types", in which both lines of the double-line may have a width other than 0
      • Support for using AutoCAD's and custom line types on specific layers
    • PipeDesigner 3D for AutoCAD (QuickPen International www.qpi-dal.com)
      • 3D modeling software for the engineering and mechanical contracting industry
      • Allows users to model complex piping systems with ease - and without having to be 3D gurus
      • Worked as a consultant on the project, as a designer, engineer, and programmer
      • Product was given high marks in Nov. 2000 issue of CADence magazine (six 10's and one 9)

Custom Mapping Services:

Our custom mapping solutions currently fall under two categories: Texas Railroad Commission (RRC) base maps and USGS DLG base maps. The RRC base maps fill a strong need for Geologists and Geophysicists doing work in Texas by showing the well locations and land grid in a graphical format that is easy to overlay, print, and manipulate with AutoCAD and other software packages. The DLG information is provided for those working in Texas and/or the rest of the country who need a good vector basemap to start with.
