The vector data include an encoding of the geographic extent of the features and a minimal number of attributes needed to identify and describe the features. (Source: Circular A16, p. 13)\r\n Also included is a digital orthographic imagery dataset. Digital orthographic imagery datasets contain georeferenced images of the Earth's surface, collected by a sensor in which object displacement has been removed for sensor distortions and orientation, and terrain relief. Digital orthoimages have the geometric characteristics of a map, and image qualities of a photograph.\r\n The Basemap datasets reflect the reference features (i.e., roads, streets, hydrographic features, political jurisdiction boundaries) needed by users to locate properties on FIRMs. (Source: Guidelines and Specifications Vol 1, p. 68)\r\n \r\n \r\n \r\n \r\n 20071116\r\n \r\n \r\n MIP Submission Date\r\n \r\n \r\n In work\r\n Unknown\r\n \r\n \r\n \r\n -160.170877\r\n -153.335015\r\n 60.985743\r\n 55.572994\r\n \r\n \r\n \r\n \r\n ISO 19115 Topic Category\r\n Transportation\r\n Hydrography\r\n Corporate boundaries\r\n Permanent benchmarks\r\n PLSS\r\n Quad boundaries\r\n imageryBaseMapsEarthCover\r\n \r\n \r\n FEMA NFIP Topic Category\r\n Basemap\r\n Orthoimage\r\n DOQ\r\n DOQQ\r\n FGDC Framework\r\n Digital Orthophoto Quad\r\n Orthophoto\r\n \r\n \r\n None\r\n REGION 10\r\n STATE AK\r\n COUNTY LAKE AND PENINSULA BOROUGH\r\n COUNTY-FIPS 164\r\n FEMA-CID 02164C\r\n COMMUNITY LAKE AND PENINSULA BOROUGH\r\n \r\n \r\n None\r\n Acknowledgement of FEMA would be appreciated in products derived from these data.

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 Orthoimagery is named according to (7.5 x 15) and (7.5 x 11.25) minute file naming conventions provided by USGS.\r\n The Basemap datasets represent all the features utilized during the study mapping process to spatially position the DFIRM information. Orthoimagery covers all affected study areas. The best available vector datasets were assembled for the remaining areas.\r\n Completeness_Report: The Basemap datasets represent 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. Orthoimagery covers all affected study areas. The best available vector datasets were assembled for the remaining areas.\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 See source citations for accuracy specifications of individual datasets.\r\n \r\n 11.5824\r\n The minimum horizontal positional accuracy for new FIRM base map data is that of the default base map - the USGS DOQs, which have an NSSDA radial accuracy of 38 feet. Data that meet higher accuracy standards are also acceptable. Accuracy of 38 feet is the same as radial root mean square error (RMSEr) of 22 feet.

The city boundaries were updated from an older version of the data by various means. The primary source of information that was used for the creation of new boundaries was the legal descriptions found within the city certificates. Other means used included rectifying status plats, digitizing features found on USGS Topographic Quadrangle maps, and digital data availible for download from borough web sites.\r\n This data set was created using the Web Extraction Tool (WET) coverage offset, region.b_city as a base data set. With information provided by the State of Alaska Department of Community and Economic Development (DCED) the city boundaries coverage was created with new updates (i.e. dissolved cities, newly incorporated city boundaries, and city boundary changes). The editing and creation of the data set was mainly performed by the legal descriptions found in the city certificate. In the event that the legal description was absent and/or means of locating areas described in the legal description was not available, other actions of editing and creating the boundaries were taken (i.e. rectification and digitizing BLM and DNR Status Plats, digitizing known boundaries and features found on USGS Topographic Quadrangle maps, and simple edits of existing boundaries such as merge, join, delete, etc.).\r\n \r\n \r\n 63360\r\n online\r\n \r\n \r\n \r\n 2003\r\n \r\n \r\n publication date\r\n \r\n BASE3\r\n Spatial and attribute information for political boundaries.\r\n \r\n \r\n \r\n \r\n L-3 Services, Inc.\r\n 200712\r\n Road Centerlines Digitized from Orthoimagery\r\n vector digital data\r\n \r\n Portland, OR\r\n L-3 Services, Inc.\r\n \r\n Road centerlines digitized from 2002 orthoimagery (BASE9, BASE10, BASE11).

Early coordination with all communities affected by a Flood Map Project is an important part of the Project Scoping Process described in Section 1.3 of these Guidelines. Therefore, the Section 1.4 1-68 Guidelines and Specifications for Flood Hazard Mapping Partners [April 2003] Mapping Partner responsible for preparing the Preliminary version of the FIRM or another assigned Mapping Partner shall send a letter to each affected community that: Describes the FIRM product; Requests pertinent information (pertinent information that is requested includes base map data; a current corporate limits map; elevation data [either electronic or hardcopy] and any engineering information that needs to be updated or added to the FIRM); Describes the minimum requirements for the submittal of data to be included in the new FIRM product, and Identifies the base map source that will be used if community data are not available or suitable. A sample version of this letter and other correspondence that may be generated during the Map Production phase of the project are presented in the FEMA Document Control Procedures Manual (FEMA, 2000).\r\n 20071201\r\n \r\n \r\n \r\n \r\n Vector\r\n \r\n \r\n \r\n \r\n \r\n State Plane Coordinate System 1983\r\n \r\n 5006\r\n \r\n 0.999900\r\n -158.000000\r\n 54.000000\r\n 1640416.666667\r\n 0.000000\r\n \r\n \r\n \r\n \r\n coordinate pair\r\n \r\n 0.008192\r\n 0.008192\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 6378137.0\r\n 298.257222\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.
