ESI |
The item ESI contains values representing the ESI shoreline type (shoreline habitat type). In many cases shorelines are ranked
with multiple codes such as 6B/3A (listed landward to seaward from left to right). The first number is the most landward shoreline type,
riprap, with fine- to medium-grained sand beaches being the shoreline type closest to the water. Singular shoreline types are listed
below. No multiple codes are listed, but all multiple codes included in the data set can be assembled from the codes described.

This data is provided 'as is'. GeoPlan relied on the integrity of the original data layer's topology. The original ESI shoreline classification and a series of data updates and conversions were completed under previous programs and contracts. In this project, a new shoreline was developed from recent Land Use/Land Cover (LULC) data provided by the five state Water Management Districts (WMDs). The ESI shoreline habitat classifications were updated using the previous classification, LULC data, and interpretation of Digital Orthophoto Quarter Quads (DOQQs), field verification, and other supporting information. Updates were made using current attributing standards and checked for completeness and topological and logical consistency. ESI GT-polygon data for wetlands were also added to the data set using recent LULC data. To finalize the data checking process, each data layer was checked using standardized forms by two GIS personnel (a technician and the GIS manager), and each attribute database was checked using several programs which test the files for missing or duplicate data, rules for proper coding, GIS topological consistencies (such as dangles, unnecessary nodes, etc.), and MICROSOFT SQL SERVER(r) to ARC/INFO(r) consistencies. |
The coastal ESI shoreline was updated during this project to the inland extent of the original ESI classification and the limit of marine and coastal waters represented as polygons in the LULC data provided by the WMDs (e.g., Atlantic Ocean, Gulf of Mexico, bays and estuaries, lower sections of coastal rivers and larger creeks, etc.). In addition, the Lower St. Johns River was updated upstream to just beyond Lake Monroe and the town of Sanford, Florida. ESI polygons and hydrography were updated to roughly 10 miles inland of the ESI shoreline. The updated shoreline position and classification was based primarily on the interpretation of LULC data, DOQQs, the previous existing classification, and the ESI expertise of coastal geologists, biologists, and GIS analysts. This update did include limited field verification, which is recommended for the entire study area. A special attribute field was used to indicate specific shoreline segments or sections of coast of highest priority for field verification. |
GeoPlan relied on the integrity of the attribute information within the original data. |
This GIS data set comprises an update to the shoreline habitat component of the Environmental Sensitivity Index (ESI) and Gulf-Wide Information System (G-WIS) databases for the coastal zone of Florida, including the lower St. Johns River. The ESI and G-WIS data suites characterize coastal habitats and resources for environmental planning and natural resource management purposes, including oil spill planning and response. The ESI and G-WIS data include three main components: shoreline habitats, sensitive biological resources, and human-use resources. The data layer described in this document contains the linear ESI (complete chains) shoreline habitat classification. There is also a separate ESIP (GT-polygon) layer for polygonal ESI habitat features (Contact FMRI). |
The ESI shoreline position is primarily based on the recent LULC data provided by the state WMDs, updated in places using recent DOQQs. The overall positional accuracy of the shoreline is therefore similar to the positional accuracy of the primary source materials, which may vary by WMD (see lineage below). It is estimated that the positional accuracy of "breaks" between individual ESI shoreline classes is roughly 50-60 meters, based on previous ESI research conducted for NOAA over the last two years. Due to the interpretation of DOQQs as a part of this project, the ESI classification update may exceed this positional accuracy. |

A note concerning data scale: Scale is an important factor in data usage. Certain scale datasetsare not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:250000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analyses. Every effort has been made to supply the user with data documentation. For additional information, see the References sectionand the Data Source Contact section of this documentation.

The most recent LULC data from the state WMDs were obtained and processed to identify and create shoreline, ESI polygon, and hydrography layers. The shoreline was then attributed with an updated ESI shoreline habitat classification and other attributes (described below) using the pre-existing ESI shoreline (from the FL G-WIS data set), LULC data, and on-screen photo-interpretation of DOQQs. DOQQs associated with the corresponding LULC data were used during this process (e.g., 1995 DOQQs were used in areas where 1995 LULC data were available). In some cases where the shoreline position derived from the LULC data differed significantly from the shoreline visible on the DOQQs, the shoreline was updated by on-screen digitizing or with supplemental shoreline supplied by FMRI. A final quality control check for completeness, topological and logical consistency, rules for geography, and database to geography relationships were checked and validated. Process Date: 20030800 |
