A note about data scale:
Scale is an important factor in data usage. Certain scale datasets are 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. 1:125000 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 analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our webpage at: <http://geoplan.ufl.edu/education.html>
Further QA/QC revealed that the NHPN version 2005.08 contains 8 polyline features (RECIDs 4000057, 4000855, 41000287, 41002220, 48000952, 72001074, 72001170, and 72001488) that are each defined by more than 500 shape points. These features will not import correctly into the workstation version of ArcInfo, which has a 500 shapepoint limit. When importing into the workstation version of ArcInfo, the 8 features will be automatically split into 2 features each. As part of this process, attributes are simply duplicated on the split features. Because of this, attributes such as MILES and KM become invalid for these features.
- GeoPlan extracted this data in shapefile format and removed facilities not located in Florida. - The shapefile was reprojected from WGS_1984 Decimal Degrees to the FGDL Albers HPGN map projection. (See "Map Projection Parameters" below). - All records were upcased. - Changed original layer name from nhpnlin to nhpn_2007. - A DESCRIPT field was added based on SIGN1 - A FGDLAQDATE field was added based on date of data processing
