These data include an encoding of the geographic extent of the features and a minimal number of attributes needed to identify and describe the features.

Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. Line segments are a set of sequentially numbered coordinate pairs. No duplicate features exist nor duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection. Point data are represented by two sets of coordinate pairs, each with the same coordinate values. Tests for logical consistency are performed by DFIRM tools topology verification software.\r\n The Basemap datasets represents all the features utilized during the study mapping process to spatially position the DFIRM information and highlights the specific prioritization process laid out in the Guidelines and Specifications Vol 1, p. 69 in their selection for use. The final selection criteria, and rational for inclusion should be outlined here, along with rational for exclusion of use of specific base map datasets if applicable.\r\n \r\n \r\n The NSSDA is used to report the horizontal accuracy of the base map data used by FEMA to produce a FIRM. The NSSDA uses radial accuracy (Accuracy) to report the radius of a circle of uncertainty, such that the true or theoretical location of a point falls within that circle 95 percent of the time. (Guidelines and Specifications Vol 1, p. 70)\r\n \r\n \r\n \r\n \r\n The DFIRM Database is compiled in conjunction with the hardcopy FIRM \r\n and the final FIS report. The specifics of the hydrologic and hydraulic analyses \r\n performed are detailed in the FIS report. The results of these studies are \r\n submitted in digital format to FEMA. These data and unrevised data from \r\n effective FIRMs are compiled onto the base map used for DFIRM publication and \r\n checked for accuracy and compliance with FEMA standards.\r\n 00010101\r\n \r\n \r\n \r\n \r\n Vector\r\n \r\n \r\n Point\r\n \r\n \r\n String\r\n \r\n \r\n GT-polygon composed of chains\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n State Plane Coordinate System 1983\r\n \r\n 3601\r\n \r\n 44.333333\r\n 46.000000\r\n -120.500000\r\n 43.666667\r\n 8202083.333333\r\n 0.000000\r\n \r\n \r\n \r\n \r\n coordinate pair\r\n \r\n 0.000328\r\n 0.000328\r\n \r\n survey feet\r\n \r\n \r\n \r\n North American Datum of 1983\r\n Geodetic Reference System 80\r\n 6378137.000000\r\n 298.257222\r\n \r\n \r\n \r\n \r\n North American Vertical Datum of 1988\r\n 0.01\r\n feet\r\n Attribute values\r\n \r\n \r\n \r\n \r\n \r\n The Basemap submission is made up of several data themes containing both spatial and attribute information.
