TITLE: FDOT RCI ROADWAYS & NHD LINEAR SURFACE WATER DRAINAGE NETWORK (1:24K) INTERSECTIONS IN FLORIDA - May 2015

Geodataset Name:       RCI_NHD24FLOW_MAY15
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Multipoint
Feature Count:         17745
GENERAL DESCRIPTION:
This dataset contains the point result of the intersection between layers FDOT_LOCALNAME_APR15 and NHD24FLOWLINE_OCT14 for the State of Florida. This layer identifies locations where FDOT roads cross/abut water drainage flowlines such as stream/river, artificial path, etc. For more information on the two base layers please see the Supplemental Information section of the metadata.

FEATURE ATTRIBUTE TABLES CODES AND VALUES:

Item
Item Description
OBJECTID Internal feature number.

Shape Feature geometry.

ROADWAY A unique 8-character identification number assigned to a roadway or section of a roadway either On or Off the State Highway System for which information is maintained in the Department's Roadway Characteristics Inventory (RCI).

RCI_DESC Name of the roadway

GNIS_ID Unique identifier assigned by GNIS

GNIS_NAME Proper name specific term or expression by which a particular geographic entity is known.

REACHCODE Unique identifier composed of two parts. The first eight digits is the subbasin code as defined by FIPS The next six digits are randomly assigned squential numbers that are unique within a Catalog Unit.

NHD_DESC GeoPlan added field based on FTYPE. Contains text description of feature type.
ArtificialPath = Abstraction to facilitate hydrologic modeling through open water bodies and along coastal and Great Lakes shorelines and to act as a surrogate for lakes and other water bodies.

Canal/Ditch = Artificial open waterway constructed to transport water, to irrigate or drain land, to connect two or more bodies of water, or to serve as a waterway for watercraft.

Coastline = Line that follows the main outline of the land, including bays, but crosses rivers at their mouths. In the NHD, the outlines of selected coastal islands are included as part of the coastline.

Connector = Known, but nonspecific, connection between two nonadjacent network segments.

Pipeline = Closed conduit, with pumps, valves and control devices, for conveying fluids, gases, or finely divided solids.

Stream/River = Body of flowing water.

Underground Conduit = A set of naturally occurring subsurface drainage channels formed from the dissolution of soluble rocks in Karst terrain or in terrain similar to karst but formed in nonsoluble rocks, as by melting of permafrost or ground ice, collapse after mining, and by outflow of liquid lava from beneath its solidified crust. Not a named feature.


LAT_DD Latitude in Decimal Degrees.

LONG_DD Longitude in Decimal Degrees.

DESCRIPT Based on the following combination of fields: NHD_DESC & RCI_DESC

FGDLAQDATE Date FGDL acquired the data from the Source.

AUTOID Unique ID added by GeoPlan


USER NOTES:
All data for this dataset are logically consistent.
This dataset is complete as of date of production.
GeoPlan relied on the integrity of the attribute information within
the original data.
Title: Florida Department Of Transportation - Local Names Of RCI Roadways - April 2015 
Geodataset Name: FDOT_LOCALNAME_APR15.shp
General Description: 
This dataset contains Roads with Local Names from the July 2015 version of the 
Florida Department of Transportation Roads Characteristics inventory (RCI) dataset. 


Title: National Hydrography Dataset - Linear Surface Water Drainage Network 1:24K - October 2014 
Geodataset Name: NHD24FLOWLINE_OCT14.shp
General Description:
This data set contains routes that make up a linear surface water drainage network.
This is the fundamental flow network consisting predominantly of stream/river and 
artificial path vector features. It represents the spatial geometry, carries the 
attributes, models the water flow, and contains linear referencing measures for 
locating events on the network. Additional NHDFlowline features are canal/ditch, 
pipeline, connector, underground conduit, and coastline. The National Hydrography
Dataset (NHD) is a feature-based database that interconnects and uniquely 
identifies the stream segments or reaches that make up the nation's surface water 
drainage system. NHD data was originally developed at 1:100,000-scale and exists 
at that scale for the whole country. This high-resolution NHD, generally developed 
at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. The 
data was originally published by the USGS then it is modified by the NHD data 
steward for Florida (FDEP). When received from FDEP, this data was originally in 
geodatabase format. When in shapefile format the data loses the network 
functionality of the geodatabase. Please contact the FDEP if you need the original 
geodatabase.

The data was created to serve as base information for use in GIS
systems for a variety of planning and analytical purposes.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.

Furthermore, the GIS data available in the FGDL are provided 'as is'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular
purpose, or non-infringement. The University of Florida GeoPlan Center
shall not be liable for any damages suffered as a result of using,
modifying, contributing or distributing the materials.

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:

DATA LINEAGE SUMMARY:
The GeoPlan Center created RCI_NHD24FLOW_MAY15.shp on May 8th, 2015.

This dataset was created by intersecting the following two layers:

Florida Department Of Transportation - Local Names Of RCI Roadways - April 2015
FDOT_LOCALNAME_APR15.shp

National Hydrography Dataset - Linear Surface Water Drainage Network 1:24K - October 2014
NHD24FLOWLINE_OCT14.shp

Intersect Process Steps:
The ArcToolbox GeoProcessing tool 'Intersect' was invoked.
The Input Features were set to:
   FDOT_LOCALNAME_APR15.shp
   NHD24FLOWLINE_OCT14.shp
The Output Feature Class was set to:
   RCI_NHD24FLOW_MAY15.shp
Join Attributes was set to:
   ALL
XY Tolerance was set to:
   Default

GNIS_NAME = Field came from NHD24FLOWLINE_OCT14.shp layer, originally called GNIS_NAME
REACHCODE = Field came from NHD24FLOWLINE_OCT14.shp layer, originally called REACHCODE
NHD_DESC = Field came from NHD24FLOWLINE_OCT14.shp layer, originally called DESCRIPT
LAT_DD = Based on the Latitude in Decimal Degrees
LONG_DD = Based on the Longitude in Decimal Degrees
DESCRIPT = Based on the Combination of: NHD_DESC & " AT " & RCI_DESC
