Golfo de Fonseca ESI; Honduras and Nicaragua: SOCECON (Socioeconomic Lines and Points)

This data set comprises the Environmental Sensitivity Index (ESI) data for Golfo de Fonseca. ESI data characterize estuarine environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. This data set contains line and point data for human-use resources.

The ESI data were collected, mapped, and digitized to provide environmental data for oil spill planning and response and for coastal zone planning and management.

DO NOT USE MAPS FOR NAVIGATIONAL PURPOSES. Besides the above warning, there are no use constraints on these data. Acknowledgment of the publishers and contributing sources listed in Data_Set_Credit (below) would be appreciated in products derived from these data.

The software packages used to develop the atlas are Environmental Systems Research Institute's ARC/INFO(r) (version 8.0.2) and ORACLE(r) RDBMS (version 8.0.5.0.0). The hardware configuration is Hewlett Packard workstations (models 715/50 and 712/80i with 4 X-terminals) with UNIX operating system (HP-UX Release A.10.20). The following files are included in the data set: bio_lut.e00, biofile.e00, biores.e00, birds.e00, esi.e00, fish.e00, hydro.e00, index.e00, invert.e00, mgt.e00, m_mammal.e00, reptiles.e00, saltpond.e00, soc_dat.e00, soc_lut.e00, socecon.e00, sources.e00, species.e00, status.e00, t_mammal.e00.

The attribute accuracy is estimated to be "good" given the years of ESI experience, the data-input methodology, the quality control review sessions, and the digital logical consistency checks.

The SOCECON data use 1:50,000 topographic quadrangles as the basemap.

Several human-use, or socioeconomic, features are included in ESI atlases. Entity points and complete chains (arcs) are digitized into the data layer SOCECON, and managed area polygonal data are stored in the data layer MGT . The SOCECON data set is linked to the data table SOC_DAT using the SOC_LUT lookup table and the items HUNUM and ID. HUNUM is a unique reference number and ID is a unique combination of the atlas number (for Golfo de Fonseca this is 104), an element specific number (SOCECON = 10) and a unique record number. The table SOC_DAT contains the human-use number (HUNUM), feature type (TYPE), name of the facility (NAME), owner/manager or contact person (CONTACT), telephone number (PHONE) [Note: Some phone numbers for Honduras and Nicaragua contain only nine digits, xxx/xxx-xxx], geographic source (G_SOURCE), and attribute source (A_SOURCE). Detailed contact information is included for select management features, where available. Source information is included for all features.

The human-use resources were obtained in either digital format or in hardcopy format on 1:50,000 scale maps or from expert knowledge. Under this project, new digital data sources were imported, projected, checked for quality control, and integrated into the spatial data structure (for selected resources). The data were checked using both digital and on-screen procedures. To finalize the data checking process, each data layer was checked using a standardized form by two GIS personnel (a technician and the GIS manager), and each attribute database was checked using several programs that test the files for missing or duplicate data, rules for proper coding, GIS topological consistencies (such as dangles, unnecessary nodes, etc.), and ORACLE(r) to ARC/INFO(r) consistencies. A final review was made by the GIS manager, where the data were written to tape and metadata were written. ESI data are processed into multiple formats to make them useful to a wider community of GIS/mapping users. Distribution formats include ARC export, MOSS and Shape files, and MARPLOT map folders. An ArcView ESI project and ESI_Viewer product are also included on the CDs for ease of use of the ESI data. The database files are distributed both in the NOAA standard relational database format (see NOAA Technical Memorandum NOS ORCA 115) and in a simplified desktop flat file format. This metadata document includes information on both of these database formats. The section Spatial_Data_Organization_Information refers to the source files in ARC export format only.
