Mapping Archaeological Surveys
Places where surveys were conducted are mapped only for archaeology. For historical/architectural surveys, the entire APE will be surveyed.
Boundaries of surveyed areas must be digitized as polygons. These polygons must represent the portions of the APE systematically covered by walkover surveys, shovel tests, excavation units, small diameter soil coring, geomorphic, or geophysical surveys and may include the entire APE. Polygons must be closed. Polygons must include one and only one survey method code. If more than one code is applicable, create separate polygons. This shapefile must be named surveypl.shp.
Attribute Table Definitions for Shapefiles
Field Name | Type | Length | Precision | Scale | Values |
---|---|---|---|---|---|
PROJ_N |
Text | 40 | 0 | 0 | Project Number, e.g. SP 73-602-17 SAP 14-599-33 CP 193-34-206 If there is no project number, enter a descriptive term to identify the project. |
SURVEY_ID |
Text | 3 | 0 | 0 | Use sequential numbers, starting with 1, to distinguish between the different surveyed places within each APE. If more than one survey layer is mapped, the numbers must continue without repeating between the layers. For example, the SURVEYPL layer may contain polygons 1-4, while the SURVEYLI layer contains line segments 5-7 and SURVEYPT contains points 8-15. |
SURV_METH | Text | 2 | 0 | 0 | Survey method: 1 - Informant report 2 – Surface survey 14 - Phase 1A (literature review & visual assessment) 15 - Monitoring (Archaeological) 16 - Monitoring (Tribal) |
ACRES | Number (Double) |
9 | 8 | 1 | Estimated size, in acres, of area surveyed. This includes the size of the area around a point or line that was considered surveyed by the point or line. Fractions (in 1/10ths of an acre) are allowed. For surveyed points, 0 is an acceptable value. |
WIDTH | Number (Float) |
46 | 5 | 1 | Distance in meters from the point or line feature represented to its outermost edge. In other words, the radius of a point or half the width of a line. Do not report the distance from one outer edge to the other outer edge. This field should be coded as 0 for polygon features, since there should be no additional feature “width” beyond the polygon’s boundaries. |
SPACING | Number (Short) |
3 | 3 | 0 | Survey spacing within area surveyed (i.e. distance between walked transects or shovel tests) in meters. This distance may be 0 for irregularly spaced transects mapped as lines or shovel tests mapped as points, but not 0 for these types of surveys mapped as polygons. A value for spacing is required if a polygon is coded as having been surveyed by any method other than informant report or literature review. A value of 0 will suffice for areas that were not surveyed. |
CONTRACTOR | Text | 30 | 0 | 0 | Name of contractor performing survey (ALL CAPS) |
MAP_METH | Text | 1 | 0 | 0 | Mapping method, e.g. 4 – Buffer centerline or point |
YEAR | Number (Short) |
4 | 4 | 0 | Year of survey |
DEPTH | Number (Float) |
6 | 5 | 1 | Maximum survey depth, to nearest 1/10th meter. |
