ANSI/<strong>NIST</strong>-ITL 1-<strong>2011</strong> - UPDATE 2013 DRAFT VERSION8.13.4 Field 13.004: Source agency/ SRCThis is a mandatory field. See Section 7.6 <strong>for</strong> details. The source agency name may beentered in Field 13.993: Source agency name / SAN.8.13.5 Field 13.005: Latent capture date / LCDThis mandatory field shall contain the date that the latent biometric data contained in therecord was captured. See Section 7.7.2.3 <strong>for</strong> details.8.13.6 Field 13.006: Horizontal line length / HLLThis field is mandatory. See Section 7.7.8.1 <strong>for</strong> details.8.13.7 Field 13.007: Vertical line length / VLLThis field is mandatory. See Section 7.7.8.2 <strong>for</strong> details.8.13.8 Field 13.008: Scale units / SLCThis field is mandatory. See Section 7.7.8.3 <strong>for</strong> details.8.13.9 Field 13.009: Transmitted horizontal pixel scale / THPSThis field is mandatory. See Section 7.7.8.4 <strong>for</strong> details.8.13.10 Field 13.010: Transmitted vertical pixel scale / TVPSThis field is mandatory. See Section 7.7.8.5 <strong>for</strong> details.8.13.11 Field 13.011: Compression algorithm / CGAThis is a mandatory field. It shall specify the algorithm used to compress the transmittedgrayscale images. See Table 15 <strong>for</strong> a list of the codes, and Section 7.7.9.1 <strong>for</strong> a detaileddescription of this field.8.13.12 Field 13.012: Bits per pixel / BPXThis field is mandatory. See Section 7.7.8.6 <strong>for</strong> details.8.13.13 Field 13.013: Friction ridge generalized position / FGPThis field is mandatory. Each subfield shall contain one possible finger, palm or plantarposition that may match the latent image, up to a maximum of 6 possibilities. The code“0” shall be used to reference every finger position from 1 to 10, 16 and 17. The code“20” <strong>for</strong> “Unknown palm” shall be used to reference every listed palmprint position. Thecode “60” <strong>for</strong> “Unknown sole” shall be used <strong>for</strong> every listed plantar position. Code “18”shall be used if it is unknown whether the print is from a hand or foot. Code “19” shall beused <strong>for</strong> a latent image that includes substantive portion of of the medial or proximalsegments of a finger, or the extreme tip of a fingerprint. If code 19 is used, fields 13.014304
