Abstract:
The data set marpits1 is an ArcInfo coverage of point features representing pit locations and attribution data captured from an atlas of map sheets and pit data sheets titled "A Materials Inventory of Maricopa County [Arizona]" by the Arizona Highway Department (AHD), now named the Arizona Department of Transportation (ADOT), hereafter referred to as the 'Source'.
Pit locations were represented by point symbols in the Source map sheets. Points were digitized from the Source map sheets. Selected attribute data were collected from the Source pit data and map sheets. In the Source introduction it states:
    "The pit location maps show the location of all
    pits bearing Materials Services serial numbers.
    Other sources are not shown. The plotted locations
    are as close as possible to the true location
    as the scale of the map will allow."
The point attribute data, captured from the Source pit data sheets are
    "designed to show test results (sieve analysis,
    plasticity index, and abrasion) for the usable
    material within each ADOT pit."
Purpose:
U. S. Geological Survey scientists desired to have the data presented in the Source in a digital format to use in GIS and spreadsheet software programs for aggregate models and aggregate assessment.
Supplemental_Information:
The digital editor and digital compilers of the GIS data set made certain adjustments to the data to make them complete and usable in a GIS. These adjustments include adding points locations for records in the accompanying Source pit data sheets where no point representation existed on the Source map sheets, adding attribution data to the furthest extent possible for points on the Source map sheets without entries in the accompanying Source pit data sheets, appending a letter to the pit number of repeated (duplicate) pit numbers to make them unique and correspond one-to-one with a record in the Source pit data sheets, and adding a '-999' to represent 'No data' or 'No observation' for blank entries in the pit data sheets. Table 3 in the Open-File Report text describes the actions taken to insure data consistency and uniqueness of the individual points. An accompanying ArcInfo arc coverage called marbase of the generalized Maricopa County boundary, and generalized major roadways and generalized major hydrography of Maricopa County has been included to give a general reference of pit location in proximity to natural and man-made features.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Attribution data captured from the Source pit data sheets were compared to the Source to check for typographical errors. Hard copy maps were produced with the pit number labeled for each pit location and manually checked.
Pit locations were infrequently found to have legal descriptions in the Source pit data sheets inconsistent with the displayed pit location on the Source map sheets. No attempt was made to update the legal descriptions shown in the Source pit data sheets.
Logical_Consistency_Report:
Point features present. Points were digitized at the center of each symbol representing a pit location on the Source map sheet. Where two or more pit number labels pointed to the same symbol a point was added for each of the labels, thus some points will overlap when displayed at the scale at which the data were digitized (1:176,306). In some cases one of the points may have been digitized slightly off-center.
Completeness_Report:
All pit locations depicted on the Source map sheets or with a record in the Source pit data sheets were captured.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Maps prepared using the digitized points overlain on the Source map sheets on a light table and suggest that the locational accuracy for the digitized points is no better than 2 millimeters (1175 feet or 358 meters at scale). Plots of the pit locations over a Public Land Survey sections GIS data set available form the Arizona State Land Department produced maps to display pit locations within PLSS sections. The result showed consistent locational fidelity between pit location and PLSS quarter-section in the digital data as compared to the Source.

Process_Description:
Data from the Source pit data sheets were entered into an Microsoft Excel spreadsheet.
The Source map sheets of pit locations consisted of 11 sheets bound in an atlas. Since the data was to be captured via a digitizer tablet, photocopies were made of the each of the Source map sheets. The digitizer was coordinated to within a RMS error of 0.004 for each digitizing session.
At least four tic locations were determined and labeled on each map photocopy. The Source map sheets did not always have known locations to use for control points (tics), requiring that a control point be added along a known longitude-latitude line or State-Plane grid line.
Pit locations on the Source map sheet were digitized on-center of the pit location symbol or in some cases very slightly off- center (see the logical consistency section), and the pit number was attributed. If a pit number was used more than once a letter was appended to make each pit number unique. Table 3 in the Open-File Report text describes the actions taken to insure data consistency and uniqueness of the individual points.
Each of the digital data sets of the Source map sheets were transformed into a common projection then joined together to form one data set for the county.

 PI -(Plasticity Index) A measure of sensitivity that aggregate
     has to moisture change and is important when aggregate is
     used in Portland cement or asphalt concrete. White (1991,
     p. 13-42) defines PI as "the difference in the Atterberg
     liquid limit and plastic limit moisture contents." It is a
     value without a unit.  A PI of 4 is the maximum allowed as
     stipulated in American Society of Testing Material (ASTM)
     test D 3515 for materials used in asphalt concrete mixtures
     (White, 1991). The Arizona Highway Department (1972) used
      several PI standards.  These include ones where PI was not
     detected or was to be less than 5 or 10 depending on
     aggregate classification.  Testing was to be executed in
     accordance with the requirements of American Association
     of State Highway and Transportation Officers T 90
     (AHD, 1972).  Maximum allowable PI values are dependent on
     which of the 50 categories of aggregate types are in effect.
     When testing determined no PI, a "NP" (no plasticity) was
     entered in the ADOT (1977) table. The Open-File Report
     authors have changed all these "NP" to zero and entered
     -999 when fields were without values.

 ABR_500 -Los Angeles (LA) abrasion test (500 rotations).
          The test used to evaluate the resistance of a coarse
          aggregate to degradation by abrasion and impact is the
          Los Angeles abrasion test (Meyer and Zeinak 1991).
          In accordance with ADOT (1990, p. 718) standard
          specifications "the percent of wear of coarse aggregate
          at 500 revolutions, when tested in accordance with the
          requirements of American Association of State Highway
          Transportation Officials (AASHTO) test T 96, shall not
          exceed 40."  The same requirement is also specified for
          the class of aggregate 1 to 4 for material used in
          subbases and bases (ADOT, 1990, p. 140).  The detail of
          Los Angeles abrasion testing procedures may have
          changed so the results found in this data release may
          not be consistent with current specifications.
          Los Angeles abrasion test results are found in just 8
          percent of the pits listed in the inventory.

 SWELL_24 -Volume change--swell (24 hours).
           Data are available giving maximum 24-hour volume
           change (AHD, 1972).  Procedures and standards
           applicable at the time of the test are not given in
           the inventory but likely may have been AASHTO 101,
           Method B (AHD, 1972, Table 703-1 and 704-1).  These
           specifications set the maximum allowed volume increase
           to 0.06.  This is the maximum for all classes of
           mineral aggregate and one class of aggregate used for
           cover materials and slurry seal.

 THR_QTR -Percent material passing the 3/4 inch sieve. Materials
          passing the 3/4 inch mesh sieve are 19 mm or less.

 NUM_4 -Percent material passing the no. 4 sieve. Materials
        passing the no. 4 mesh sieve are 4.75 mm or less.

 NUM_8 -Percent material passing the no. 8 sieve. Materials
        passing the no. 8 mesh sieve are 2.338 mm or less.

 NUM_40 -Percent material passing the no. 40 sieve. Materials
         passing the no. 40 mesh sieve are 0.42 mm or less.

 NUM_200 -Percent material passing the no. 200 sieve. Materials
          passing the no. 200 mesh sieve are less than 0.074 mm.
