For instance, there are <br />substantial coordinate shifts (up to 2 meters) from GCES era control work as <br />compared to most recent GPS results; indeed many of these datasets have been <br />simply referenced to an ambiguous local coordinate system, These coordinate errors <br />then apply to all spatial data referenced to these positions, The control point database <br />accurately referenced to the geodetic control network is essential to the GIS because <br />it will allow researchers to perform spatial analysis of previously or historically <br />collected spatial data (along with all associated errors) with the most recent data <br />referenced to the National Spatial Reference System, <br /> <br />REFERENCES: <br /> <br />Federal Geographic Data Committee (1998) FGDC Content Standard for <br />Digital Geospatial Metadata, version 2, FGDC-STD-OOI-1998, 90 pp. <br />[available online at <br />http://www.fl!dc.l!ov/standards/documents/standards/metadatalv2 0698.pdfl <br /> <br />Federal Geographic Data Committee (1998) Geospatial Positioning Accuracy <br />Standards, FGDC-STD-007.2-1998, Federal Geographic Data Committee, <br />Reston, Virginia, USA, 128 pp. [available online at <br />bttp://www.fedc.l!ov/standards/documents/standards/accuracvl ) <br /> <br />Federal Geographic Data Committee (2000) Content Standard for Digital <br />Geospatial Metadata Workbook, Version 2.0, 122 pp. Federal Geographic <br />Committee, c/o USGS, Reston, V A, 126 pp. [available online at <br />http://libraries.mit.edu/l!:is/teach/workbook 0501 bmk.pdfl <br /> <br />Federal Register (1994)Volume 59 Number 71, pp17671-17674 Coordinating <br />Geographical Data Acquisition and Access: the National Spatial Data <br />Infrastructure. <br />htto:llwww.fl!dc.l!ov/publications/documents/eeninfo/execord.html <br /> <br />Office of Management and Budget Circular A-16 (2002) National Spatial Data <br />Infrastructure[available online at <br />htto://www.whitehouse.l!:ov/omb/circulars/a016/aOI6rev.htmIJ <br /> <br />For additional information, please contact: <br /> <br />Document Reference: FY06 Master Draft AMP Budgel- BOR GCMRC 02117/05 t 1:05 AM <br />
