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.

The GeoPlan Center created RCI_NHD24FLOW_APR18.shp on 4/24/18. This dataset was created by intersecting the following two layers: Florida Department Of Transportation - Local Names of RCI Roadways - April 2018 FDOT_LOCALNAMES_APR18.shp National Hydrography Dataset - Linear Surface Water Drainage Network 1:24K - December 2017 NHD24FLOWLINE_DEC17.shp Intersect Process Steps: The ArcToolbox GeoProcessing tool 'Intersect' was invoked. The Input Features were set to: FDOT_LOCALNAMES_APR18.shp NHD24FLOWLINE_DEC17.shp The Output Feature Class was set to: RCI_NHD24FLOW_APR18.SHP Join Attributes was set to: ALL XY Tolerance was set to: Default Output Type was set to: POINT Spatial Join Process: target = RCI_NHD24FLOW_APR18.shp Join Features = USCG_BND Join Operation was set to: JOIN_ONE_TO_ONE Keep All Target Features was checked Match Option was set to: Intersects (in the future consider CLOSEST) After spatial join look for records that have USCG null and attribute to the closest USCG District. GeoPlan added and/or populated the following fields: ROADWAY = Field came from FDOT_LOCALNAME layer, originally called ROADWAY RCI_DESC = Field came from FDOT_LOCALNAME layer, originally called DESCRIPT GNIS_ID = Field came from NHD24FLOWLINE layer, originally called GNIS_ID GNIS_NAME = Field came from NHD24FLOWLINE layer, originally called GNIS_NAME REACHCODE = Field came from NHD24FLOWLINE layer, originally called REACHCODE NHD_DESC = Field came from NHD24FLOWLINE layer, originally called DESCRIPT LAT_DD = Based on the Latitude in Decimal Degrees LONG_DD = Based on the Longitude in Decimal Degrees USCG = Based on USCG field from USCG_BND MGRS = MGRS ID calculated using toolbox tool: Convert Coordinate Notation with GOOGLEMAP = "https://www.google.com/maps/place/" & [MGRS] GCID DESCRIPT = Based on the Combination of: NHD_DESC & " AT " & RCI_DESC FGDLAQDATE = Date FDOT_LOCALNAME_APR18 acquired from the Source. Notes for field calculations: Lat_DD Double (Calc geometry to decimal degrees, wgs84) LONG_DD Double (Calc geometry to decimal degrees, wgs84) MGRS 15 String GOOGLEMAP 100 String GCID Long (FID or OBJECTID + 1) To calculate the MGRS field you must use the following: ArcToolbox > Convert Coordinate Notation Input Coordinate Format = DD_2 (Longitude and latitude values are in two separate fields.) X = LONG_DD Y = Lat_DD Output Coordinate Format = MGRS After this layer gets created two layers must be created: RCI_NHD24FLOW_USCG_D7 RCI_NHD24FLOW_USCG_D8 -to create these layers select from RCI_NHD24FLOW based on USCG district RCI_NHD24FLOW_DISSOLVE_D7 RCI_NHD24FLOW_DISSOLVE_D8 -to create these layers dissolve above layers Process Date: 20180424 |
