FIELD MEASUREMENT PROCEDURES: HORIZONTAL ANGLE OBSERVATIONS Horizontal angles are to be collected in the field as horizontal angles to the right, with the instrument occupying and backsighting coordinated points and foresighting the noncoordinated point. All observations will be recorded in the field book A complete set of horizontal angles will consist of 1 direct and 1 indirect observation to each target for a total of 4 observations per set. Said angles will be doubled in the indirect position. Rejection limit: an observation set will be rejected in the field if the mean of the doubled angle does not agree with the initial angle within 10 seconds of arc. 2 complete sets of angles will be required for each measurement, except for redundant measurements made from points on the control line for the purpose of positional verification, in which case 1 set will be required. (please see monument tie procedures below) The mean value of the field angles will be recorded in the field book while in the field. DISTANCE OBSERVATIONS Distances measured with the EDM will be measured in feet and meters as described below Distances measured in feet will be recorded in slope and horizontal modes if the EDM is capable. distances measured in meters will be recorded in slope mode only and will be shown in parenthesis under the slope column in the field book. Distances measured under 80 feet will additionally be measured with a steel tape to verify the EDM measurement Vertical angles will be measured and recorded in direct and indirect modes for each distance measured. MONUMENT TIE PROCEDURES: SIDE TIES FROM GPS POINTS: In order to verify the position of monuments tied or set from GPS control points, it will be required to set a point on line with the other GPS control point being backsighted to re -tie said monument.

SIDE TIES FROM TRAVERSE CONTROL: If a corner position can not be occupied in the course of a field traverse 2 sets of doubled angles turned from the backsight and the foresight will be required for a positional check TRAVERSE TIES FROM GPS POINTS: Monument positions which require a traverse to be run will be performed by close loop traverse or traverse originating and closing on GPS base lines. All traverses will have a closing angle turned and recorded for angle balancing. MONUMENT REFERENCING PROCEDURES: All GPS or land boundary monuments set or tied during the course of the project should be referenced to a minimum of three points in the vicinity of the monument if reasonably available. Said references should be measured horizontally to the nearest one hundredth of a foot. Bearings should be referenced to magnetic north and stated so in the notes. The declination used shall also be recorded in the notes. A separate field note page will be used for each referenced monument. EQUIPMENT CALIBRATION: All EDM's will be calibrated to the NGS base line established at William R. Fairchild International Airport, Clallam County, Washington prior to making field measurements. Steel tapes will be compared with the tape calibration monuments as established along said base line. All tribrachs will be adjusted prior to making field measurements. MINIMUM CLOSURE REQUIREMENTS AND CALCULATIONS: The minimum linear of closure after angle adjustment will be 1:40,000. Angular closure will not exceed 10 seconds times the square root of the number of sides in the traverse.

It is anticipated that these ASPRS standards may form the basis for revision of the U.S. National Map Accuracy Standards for both small-scale and large -scale maps. A major feature of these ASPRS standards is that they indicate accuracy at ground scale. Thus, digital spatial data of known ground -scale accuracy can be related to the appropriate map scale for graphic presentation at a recognized standard. These standards concern the definitions of spatial accuracy as they pertain to large -scale topographic maps prepared for special purposes or engineering applications Emphasis is on the final spatial accuracies that can be derived from the map in terms most generally understood by the users. 1. Horizontal Accuracy: Horizontal map accuracy is defined as the rms errors in terms of the project's planimetric survey coordinates (X,Y) for checked points as determined at full (ground) scale of the map. The rms error is the cumulative result of all errors including those introduced by the processes of ground control surveys, map compilation and final extraction of ground dimensions from the map. The limiting rms errors are the maximum permissible rms errors established by this standard. These limiting rms errors for Class 1. maps are tabulated in Table lE (feet) and Table 1M (meters) along with typical map scales associated with the limiting errors. These limits of accuracy apply to tests made on well- defined points only PLANIMETRIC (X OR Yl ACCIJRACY TYPICAL MAP SCALE (limiting rms error, feet) 0.05 1:60 0.1 1:120 0.2 1:240 0.3 1:360 0.4 1:480 0.5 1:600 1.0 1:1,200 2.0 1:2,400 4.0 1:4,800 5.0 1:6,000 8.0 1:9,600 10.0 1:12,000 16.7 1:20,000 Table 1 E.

Planimetric Coordinate Accuracy Requirement (ground X or Y in meters) of Well defined Points Class 1. Maps *indicates the practical limit for aerial methods for scales above this line, ground methods are used 2. Vertical Accuracy: Vertical map accuracy is defined as the rrns error in elevation in terms of the project's elevation datum for well defined points only. For Class 1. maps the limiting rrns error in elevation is set by the standard at pne third the indicated contour interval for well defined points only. Spot heights shall be shown on the map within a limiting rms error of one -sat of the contour interval. 3. Lower Accuracy Maps: Map accuracies can also be defined at lower spatial accuracy standards. Maps compiled with limiting Tins errors of twice or three times those allowed for a CIass 1. map shall be designated Class 2. or Class 3. maps respectively. A map may be compiled that complies with one class of accuracy in elevation and another in plan. Multiple accuracies on the same map are allowed provided a diagram is included which clearly relates segments of the map with the appropriate map accuracy class. 4. Map Accuracy Tests Tests for compliance of a map sheet are optional. Testing for horizontal accuracy compliance is done by comparing the planimetric (X and Y) coordinates of well defined ground points to the coordinates of the same points as determined by a horizontal check survey of higher accuracy. The check survey shall be designed according to the Federal Geodetic Control Committee (FGCC) [FGCC, 1984] standards and specifications to achieve standard deviations equal to or less than one -third of the "limiting rms error" selected for the map. The distance between control points (d) used in the FGCC standard for the design of the survey shall be the horizontal ground distance across the diagonal dimension of the map sheet. Testing for vertical accuracy compliance shall be accomplished by comparing the elevations of well defined points as determined from the map to corresponding elevations determined by a survey of higher accuracy. For purposes of checking elevations, the map position of the ground point may be shifted in any direction by an amount equal to twice.the limiting rms error in position. The vertical check survey should be designed to produce rms errors in elevation differences at check point locations no larger than 1/20th of the contour interval. The distance (d) between bench marks used in the FGCC standard for the design of the survey vertical check survey shall be the horizontal ground distance across the diagonal of the map sheet. Generally, vertical control networks based on surveys conducted according to the FGCC standards for Third Order provide adequate accuracy for conducting the vertical check survey. Discrepancies between the X, Y or Z coordinates of the ground point, as determined from the map and by the check survey, that exceed three times the limiting rms error shall be interpreted as blunders and will be corrected before the map is considered to meet this standard. The same survey datums, both horizontal and vertical, must be used for both the project and the check control surveys. Although a national survey datum is preferred, a local datum is acceptable. A minimum of 20 check points shall be established throughout the area covered by the map and shall be distributed in a manner agreed upon by the contracting parties Maps produced according to this spatial accuracy standard shall include the following statement in the tide block: THIS MAP WAS COMPILED TO MEET THE ASPRS STANDARD FOR CLASS 1. MAP ACCURACY If the map was checked and found to conform to this spatial accuracy standard, the following statement shall also appear in the tide block: THIS MAP WAS CHECKED AND FOUND TO CONFORM TO THE ASPRS STANDARD FOR CLASS I. MAP ACCURACY lsee Appendix A., Section Al. -see Appendix A., Section A2. 3 see Appendix A., Section A3. 4 see Appendix A., Section A4. 5 see Appendix A., Section AS. APPENDIX A. EXPLANATORY COMMENTS Al. Root Mean Square Error The "root mean square" (rms) error is defined to be the square root of the average of the squared discrepancies. In this case, the discrepancies are the differences in coordinate or elevation values as derived from the map and as determined by an independent survey of higher accuracy (check survey). For example, the rms error in the X coordinate direction can be computed as: rms V (D' ;n) where: D dl d2. d d discrepancy in the X coordinate direction map X check 11 total number of points checked on the map in the X coordinate direction 3 A2. Well defined Points The term-"well-defined points" pertains to features that can be sharply identified as discrete points. Points which are not well- defined (that is poorly defined) are excluded from the map accuracy test. In the case of poorly defined image points, these may be of features that do not have a well defined centers such as roads that intersect at shallow angles (U.S. National Map Accuracy Standards, 19411. In the case of poorly defined ground points, these may be such features as soil boundaries or timber boundaries. As indicated in the ASPRS Standard, the selection of well- defined points is made through agreement by the contracting parties. A3. Relationship to U.S. National Map Accuracy Standards Planimetric accuracy in terms of the "limiting rms error" can be related to the United States National Map Accuracy Standards (NMAS) provided the following assumptions are made: the discrepancies are normally distributed about a zero mean the standard deviations in the X and Y coordinate directions are equal sufficient check points are used to accurately estimate the variances To compute the circular map accuracy standard" (CMAS) which corresponds to the 90% circular map error defined in the NMAS (ACIC, 1962, p. 26, p. 411: CMAS 2.146 a or, CHAS 2.146 a Given these relationships and assumptions, the limiting rms errors correspond approximately to the CMAS of 1 /47th of an inch for all errors and related scales indicated in Table 1E. For the metric case indicated in Table 1M, the CMAS is 0.54mm for all rms erros and corresponding scales. It is emphasized that for the ASPRS Standard, spatial accuracies are stated and evaluated at full or Around scale. The measures in terms of equivalent CMAS are only approximate and are offered only to provide a comparison to the National Map Accuracy Standard of CMAS of 1/30th inch at map scale. A4. Check Survey Both the vertical and horizontal (planimetric) check surveys are designed based on the National standards of accuracy and field specifications for control surveys established by the Federal Geodetic Control Committee (FGCC). These standards and specifications (FGCC, 19841 are intended to establish procedures which produce accuracies in terms of relative errors. For horizontal surveys, the proportional accuracies for the various orders and classes of survey are stated in Table 2.1 of the FGCC document and for elevation accuracy in Table 2.2. These tables along with their explanations are reproduced here. From FGCC (19841: "2.1 HORIZONTAL CONTROL NETWORK STANDARDS When a horizontal control point is classified with a particular order and class, NGS certifies that the geodetic latitude and longitude of that control point bear a relation of specific accuracy to the coordinates of all ocher points in the horizontal control network. This relationship is expressed as a distance accuracy, 1:a. A distance accuracy is the ratio of relative positional error of a pair of control points to the horizontal separation of those points. H Classification First -order Second- order, class I Second- order; class II Third- order, class I Third- order, class II where Classification First- order, class I First- order, class II Second order, class I Second order, class II Third -order where Table 2.1 Distance accuracy standards "A distance accuracy, 1:a, is computed from a minimally constrained, correctly weighted, least squares adjustment by: a=d/s a distance accuracy denominator s propagated standard deviation of distance between survey points obtained from the least squares adjustment d distance between survey points "VERTICAL CONTROL NETWORK STANDARDS When a vertical control point is classified with a particular order and class, NOS certifies that the orthometric elevation at that point bears a relation of specific accuracy to the elevations of all other points in the vertical control network. That relation is expressed as an elevation difference accuracy, b. An elevation difference accuracy is the relative elevation error between a pair of control points that is scaled by the square root of their horizontal separation traced along existing level routes. Table 2.2- Elevation accuracy standards "An elevation difference accuracy, b, is computed from a minimally constrained, correctly weighted, least squares adjustment by b =S /i d approximate horizontal distance in kilometers between control point positions traced along existing level routes. S propagated standard deviation of elevation difference in millimeters between survey control points obtained from a least squares adjustment. Note that the units of b are (mm)/ (km)." Minimum distance accuracy 1:100,000 1: 50,000 1: 20,000 1: 10,000 I: 5,000 Minimum elevation difference accuracy 0.5 0.7 1.0 1.3 2.0 For an example of designing a check survey (selecting an order and class), assume that a survey is to be designed to check a map which is intended to possess a planimet c (horizontal) "limiting rms error" (see Table 1 E. of the map standard) of one foot and a contour interval of ma feet. In contrast to survey accuracies, which are stated in terms of relative horizontal distances to adjacent points, map features are intended to possess accuracies relative to all other points appearing on the map. Therefore, for purposes of the check survey, the distance between survey points (d) is taken as the diagonal distance on the ground across the area covered by the map. According to the FGCC survey standards this is the distance across which the "minimum distance accuracy" and "maximum elevation difference accuracy" is required (see Table 2.1 and 2.2 of the [FGCC,1984) document). For the planimetric check survey, assume that the diagonal distance on the ground covered by the map is 6000 feet. The propagated standard deviation (s) required for the check survey is one -third of the limiting rims error of one foot or 0.33 foot in this example. Returning to the equation from the FGCC 19841 document relating distance between survey points (d), standard deviation (s) and distance accuracy denominator (a); a=d/s =(6000 feet) /(0.33 feet)= 18,182 By referring to Table 2.1 of the FGCC document, it is clear that a control survey designed according to the standards and specifications for second- order. class Ii is required to produce the horizontal check survey for this example. If the project control survey is conducted at a standard of accuracy equal to or better than second order, class II, the check survey can tie to the project control network in accord with FGCC standards. For the vertical check survey, the distance (d) is also taken as a diagonal ground distance across the map to account for the fact that elevation accuracy pertains to all mapped features. The propagated standard deviation in elevation (S) is required by this standard to be equal or less than 1/20th of the contour interval of two fee S (1/20) CI 0.10 feet Returning to Table 2.2 of the FGCC document, relating distance between bench marks (d in km), the standard deviation in elevation (S in mm), and the elevation difference accuracy (b); where; then; S =0.10 feet 30.3mm d 6000 feet 1.181 km b S/ d 28.1 tnrn/ It is clear that a third -order survey for elevation differences is more than adequate for purposes of conducting the check survey for this map example. Other methods for conducting the check survey for elevation are acceptable provided they have demonstrated accuracy capability equal to that required by this map standard. Such departures however must be agreed upon by the contracting parties prior to conducting the survey. Due to the diversity of requirements anticipated for any large scale special purpose or engineering map, it is not realistic to include statements that specify the spatial distribution of check points designed to assess the spatial accuracy of the map. For instance, it may be preferred to distribute the check points more densely in the vicinity of important structures or drainage features and more sparsely in areas that are of little or no interest. Of course suitable notation, such as a change in map class for the region of lesser interest, should be included accordingly on the map sheet. For a map sheet, however, of conventional rectangular dimensions, intended to portray a uniform spatial accuracy over the entire map sheet, it may be reasonable to specify the distribution. For instance, given the minimum of twenty check points, it could be specified that at least 20% of the points be located in each quadrant of the map sheet and that these points be spaced at intervals equal to at least 10% of the map sheet diagonal.
