Abstract:

This dataset consists of information about the points of established position and third-order or better elevations that are used as fixed references in positioning and correlating map features.

Purpose:

This dataset consists of information about the points of established position and third-order or better elevations that are used as fixed references in positioning and correlating map features.

THE DATA INCLUDED IN THIS APPLICATION ARE BASED ON INTERPRETATION OF AVAILABLE INFORMATION AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING.

Scale is an important factor in data usage. Certain scale data sets are not suitable for some projects, analysis, or modeling purposes. Please be sure you are using the best available data.

1:24000 scale data sets 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 data sets are recommended for projects that are at the multi-county or regional level. 1:250000 scale data sets are recommended for projects that are at the regional or state level or larger.

This dataset covers the following counties: Alachua, Baker, Brevard, Broward, Charlotte, Citrus, Collier, Columbia, Dade, Desoto, Escambia, Hardee, Levy, Manatee, Marion, Monroe, Nassau, Orange, Palm Beach, Putnam, Santa Rosa, Sarasota, Seminole, and Volusia.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Relied on the integrity of the attribute information within the original data layer. An elevation of -9999.990 indicates that there is no elevation data for a particular point. The point coverage described in this document was derived from USGS topographic maps published as 7.5-minute quadrangles at 1:24,000 scale.

Logical_Consistency_Report:

Certain node/geometry and topology (GT)-polygon/chain relationships are collected or generated to satisfy topological requirements. Some of these requirements include: chains must begin and end at nodes, chains must connect to each other at nodes, chains do not extend through nodes, left and right GT-polygons are defined for each chain element and are consistent throughout the transfer, and the chains representing the limits of the file (neatline) are free of gaps. The neatline is generated by connecting the four corners of the digital file, as established during initialization of the digital file. All data outside the enclosed region are ignored and all data crossing these geographically straight lines are clipped at the neatline. (Exception: During the QA/QC process all data is examined and if errors are found and corrections are possible, then data is corrected accordingly. This process is documented in the Process_Step.) Data within a specified tolerance of the neatline are snapped to the neatline. Neatline straightening aligns the digitized edges of the digital data with the generated neatline, that is, with the longitude/latitude lines in geographic coordinates. All internal polygons are tested for closure. Certain attributes and/or entities, e.g. closure line, convey data quality information. When information to be encoded in the subfield is known to be not applicable (undefined, not relevant), then the subfield is valued by a string of "9s"; and when the information to be encoded is relevant but unknown (or missing), then the subfield is valued by a string of "9s."

Process_Step:

Process_Description:

The process step describes, in general, the process used in the production of data sets. The originating agencies created the original spatial coverage. GeoPlan, during the QA/QC process included the following aspects: (1) Reprojected data to FGDL Albers (2) Set Precision to DOUBLE (3) Set Tolerances to FGDL Standards. (4) Added the DESCRIPT item based on Elevation data in meters. (5) Joined the feature attribute tables and the related elevation tables (.asmf) of the original quad coverages.
