Title: Digital Orthophoto Quadrangle
Geospatial_Data_Presentation_Form: digital vector data
Publication_Information: Publication_Place: Eros Data Center, Sioux Falls, SD
Publisher: U.S.Geological Survey
Other_Citation_Details: The digital orthophoto quadrangle (DOQ) is a 1-meter ground resolution, quarter-quadrangle (3.75-minutes of latitude by 3.75-minutes of longitude) image cast on the Universal Transverse Mercator Projection (UTM) on the North American Datum of 1983 (NAD83). The imagery is based on panchromatic black and white (or color infr-red) NAPP or NAPP-like photography. From the raster DOQs, a vector index is created.

Other_Citation_Details: Geodetic data comprise the results of geodetic surveys to determine among other things, latitude, longitude, height, scale, and orientation control. The NGS' final product is the geodetic data sheet. Geodetic data sheets are comprehensive summaries of all the published information for a given geodetic reference point, including: the geographic position and/or height based on the current reference datum, condition of the survey mark when it was last visited, a description of where the point is located and how to reach it, and an explanation of the terms used in the data sheet.

Other_Citation_Details: NAIP quarter quads are aerial photo quarter quads produced for the National Agricultural Imagery Program (NAIP) and are comprised of scanned photographs that were acquired with a precision aerial mapping camera at a nominal scale of 1:40,000 on color positive film. Acquisition was leaf on with mature crops prior to harvest. The aerial film was scanned and digitally rectified at a resolution of approximately two meters GSD for use as a visual interpretation tool and to take area measurements of farm fields to within +/- 5% accuracy.

Process_Step: Process_Description: The DFIRM Database is compiled in conjunction with the hardcopy FIRM and the final FIS report. The specifics of the hydrologic and hydraulic analyses performed are detailed in the FIS report. The results of these studies are submitted in digital format to FEMA. These data and unrevised data from effective FIRMs are compiled onto the base map used for DFIRM publication and checked for accuracy and compliance with FEMA standards.

The FIRM is the basis for floodplain management, mitigation, and insurance activities for the National Flood Insurance Program (NFIP). Insurance applications include enforcement of the mandatory purchase requirement of the Flood Disaster Protection Act, which "... requires the purchase of flood insurance by property owners who are being assisted by Federal programs or by Federally supervised, regulated or insured agencies or institutions in the acquisition or improvement of land facilities located or to be located in identified areas having special flood hazards, " Section 2 (b) (4) of the Flood Disaster Protection Act of 1973. In addition to the identification of Special Flood Hazard Areas (SFHAs), the risk zones shown on the FIRMs are the basis for the establishment of premium rates for flood coverage offered through the NFIP. The FIRM Database presents the flood risk information depicted on the FIRM in a digital format suitable for use in electronic mapping applications. The FIRM Database serves to archive the information collected during the Flood Risk Project.

The DFIRM Database consists of countywide vector files and associated attributes produced in conjunction with the hard copy FEMA FIRM. The published effective FIRM and DFIRM maps are issued as the official designation of the SFHAs. As such they are adopted by local communities and form the basis for administration of the NFIP. For these purposes they are authoritative. Provisions exist in the regulations for public review, appeals and corrections of the flood risk information shown to better match real world conditions. As with any engineering analysis of this type, variation from the estimated flood heights and floodplain boundaries is possible. Details of FEMA's requirements for the FISs and flood mapping process that produces these data are available in the Guidelines and Specifications for Flood Hazard Mapping Partners. Attribute accuracy was tested by manual comparison of source graphics with hardcopy plots and a symbolized display on an interactive computer graphic System.

Location and attributes of flood hazards. This table is required for all draft Digital Flood Insurance Rate Map data. The S_Fld_Haz_Ar table contains information about the flood hazards within the study area. A spatial file with locational information also corresponds with this data table. These zones are used by the federal Emergency Management Agency (FEMA) to designate the Special Flood Hazard Area (SFHA) and for insurance rating purposes. These data are the flood hazard areas that are or will be depicted on the Flood Insurance Rate Map (FIRM). A spatial file with locational information also corresponds with this data table. The spatial elements representing the flood zones are polygons. The entire area of the jurisdiction(s) mapped by the FIRM should have a corresponding flood zone polygon. There is one polygon for each contiguous flood zone designated. This is a modified Standard DFIRM Database table that includes Standard DFIRM Database items and Enhanced Database items. All items after SOURCE_CIT are Enhanced. This data was received from FEMA, clipped to the County of San Diego, and renamed to HYD_FLOODPL.

This column is a County of San Diego-derived column generated by the FLOOD_ZONE column or the combination of FLOOD_ZONE and FLOOD_SUBTY, describing the type of floodplain where:
FP500 is 500-year floodplain
FP100 is 100-year floodplain
FW100 is 100-year floodway
' ' is a no value
FLOOD_PLAI values are determined by the following method:
FP500 where:
"FLD_ZONE" = 'X' AND
"ZONE_SUBTY" = '0.2 PCT ANNUAL CHANCE FLOOD HAZARD'
FP100 where:
"FLD_ZONE" = 'A' OR
"FLD_ZONE" = 'A99' OR
"FLD_ZONE" = 'AE' OR
"FLD_ZONE" = 'AH' OR
"FLD_ZONE" = 'AO' OR
"FLD_ZONE" = 'VE'
FP100 also where:
"FLD_ZONE" = 'AE' AND
"ZONE_SUBTY" = '1 PCT ANNUAL CHANCE FLOOD HAZARD CONTAINED IN CHANNEL'
FW100 where:
"FLD_ZONE" = 'AE' AND "ZONE_SUBTY" = 'FLOODWAY'
" " or blank where:
"FLD_ZONE" = 'D'
" " or blank also where:
"FLD_ZONE" = 'X' AND "ZONE_SUBTY" = 'AREA OF MINIMAL FLOOD HAZARD'
Note:
1-percent-annual-chance equates to 100-year.
0.2-percent-annual-chance equates to 500-year.

FEMA's FIRM Database Technical Reference contains a detailed description of each attribute code and a reference to other relevant information
The NFHL is made up of several data themes containing both spatial and attribute information. These data together represent the current flood risk for the subject area as identified by FEMA. The attribute tables include SFHA locations, flood zone designations, BFEs, political entities, cross-section locations, FIRM panel information, and other data related to the NFIP.
DFIRM_ID is Study Identifier.
FLD_AR_ID is a primary key for table lookup. Assigned by FEMA table creator.
FLD_ZONE is Flood Zone. This is a flood zone designation.
ZONE_SUBTY is Flood Zone Subtype. Subcategory areas within the Flood Zone.
FLOODWAY is an abandonded column (kept to avoid breaking any mapping applications). The contents of the column is included in columnn ZONE_SUBTY. SFHA_TF is Special Flood Hazard Area. If the area is within a SFHA this field would be true.
STATIC_BFE is Static Base Flood Elevation.
V_DATUM is Vertical Datum, the reference surface from which the flood elevations are measured.
DEPTH is depth. LEN_UNIT is Length Units. This unit indicates the measurement system used for the BFEs and/or depths. Normally feet.
VELOCITY is the velocity measurement of the flood flow in the area.
VEL_UNIT is Velocity Unit. This is the unit of measurement for the velocity.
AR_REVERT is Flood Control Restoration Zones – Zone AR Classification.
BFE_REVERT is Flood Control Restoration Zones – BFE Revert.
DEP_REVERT is Flood Control Restoration Zones – Depth Revert.
SOURCE_CIT is Source Citation.
HYDRO_ID is Hydrologic Model Identification. CST_MDL_ID is Coastal Model Identification.
FLOOD_PLAI is type of flood plain (County of San Diego-created column)
