Title: Populated Places
Status: Completed
Publication Date: 2018-03-30
Abstract:

This data included the Populated Places dataset from the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics’ (BTS's) National Transportation Atlas Database (NTAD). Including cities and towns in the United States, Puerto Rico, and the U.S. Virgin Islands. As well as the DEC2010_IslandAreas & Place_2010Census_ DP1 TIGER/Line shapefiles from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB) for all U.S. Territories which are not included in the USGS National Atlas. The boundaries of all CDPs were delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2010 Census. Populated places were buffered from the coastline to gather only coastal cities & all other inland cities were removed. The cities remaining were divided into 4 groupings based on population & underwent a thinning process based on a 5 mile buffer of any grouping with a larger population. Cities left were guaranteed to be 5 miles apart if they were from different groupings. Areas with dense coastal lying places had any remaining inland cities removed. Utilizing the Raster Navigational Charts from NOAA started at Alaska & working down the coastline extraneous places from the center of land out to the coastline from smallest to largest were removed, assuring that cites that existed on the RNC remained, or a city with the largest population near the coast & close to an RNC designated city remained. Territory Island data from the U.S. Census was then merged with this data set so that it contained places for all U.S. populated places & territories. (The U.S. Census data was turned into a point feature utilizing the feature to point tool, the points are a representation of the centroid of the U.S. Census's polygon shapefile.) sparse or areas had places added from the U.S. Census Places dataset if the area was too sparse after this process. This dataset is not meant to be all inclusive, and only includes some coastal populated places in the U.S. and it's territories for NOAA's Ocean Reporting Tool.

Purpose:

This layer is an amalgamation of the Populated Places dataset from the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics’ (BTS's) National Transportation Atlas Database (NTAD) which includes cities and towns in the United States, Puerto Rico, and the U.S. Virgin Islands. As well as, DEC2010_IslandAreas & Place_2010Census_ DP1 TIGER/Line shapefiles from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB) for all U.S. Territories which are not included in the USGS National Atlas. This dataset is not meant to be all inclusive, and only includes some coastal populated places in the U.S. and it's territories for NOAA's Ocean Reporting Tool.

Supplemental Information:

The native coordinate system for this layer is WGS 1984 World Mercator (ESPG: 3395). Please note: all MarineCadastre.gov data served by the NOAA Office for Coastal Management and hosted through Esri REST services are in the WGS 1984 Web Mercator Auxiliary Sphere (EPSG: 3857) projection.

Process Steps

Process Step 1

CC ID: 792166
Description:

Created State_Name, State, Place_Name & Census2010 Columns & populated them accordingly. Then Selected by Attribute cites based on population and export them into 4 independent point files with appropriate names - 4 levels of importance: Huge Cities >100K , Big Cities >10k but not including Huge , Medium Cities > 1k but not including Big & Huge, & Tiny Cities > 0 population but not including Medium, Big, & Huge. I called these layers, PP_CCHUGE, PP_CCBIG, PP_CCMED, & PP_CCTINY. Allow the 4 new layers of cites to be added to your map. Created a 5 mile buffer for the 3 largest layers.

Process Date/Time: 2018-04-03 00:00:00

Process Step 2

CC ID: 792167
Description:

Before Removing any cites from these 4 city layers, duplicate each one of them & name it with REMOVED at the end. Remove the original layers= PP_CCHUGE, PP_CCBIG, PP_CCMED, & PP_CCTINY from your map so that you do not remove cities from them as it will be easier later to add a city back in from one of these layers if needed. Working with your PP_CCHUGE_REMOVED, PP_CCBIG_REMOVED, PP_CCMED_REMOVED, & PP_CCTINY_REMOVED - Utilized the Huge_5mileBuffer to remove any city from the Big, Med, or Tiny falling within the Huge buffer using the select by location tool. Utilized the Big_5mileBuffer to remove any Med & Tiny city within the Big buffer using the select by location tool. Utilized the Med_5mileBuffer to remove any Tiny city within the Med buffer using the select by location tool.

Process Step 3

CC ID: 792168
Description:

Connected the ACS 2013 3YR total population estimates via the GEOID's provided & re-creating Place_Name within the ACS table. Copied population estimates to a created ACS_2013_3YR_Estimate attribute in Populated Places. Visually inspect information & fill in possible missing estimates using AmericanFact Finder for 2013 census data.

Process Date/Time: 2018-04-09 00:00:00

Process Step 4

CC ID: 792169
Description:

Starting with US Census data - Place_2010Census_DP1 & DEC2010_IslandAreas. Shapefiles were downloaded for the US & Territories (which were separate) All feature classes were then Projected into World Mercator Each feature from the downloaded geodatabase had to be run through Feature to Point Tool-to make a point file for the centroid of the area Created: State_Name, State, Place_Name & Census2010 columns & populated them accordingly. Merged the 4 territories into one Census2012Territory Points shapefile. Fixed exotic place names that did not come into ArcGIS correctly because of unrecognized characters.

Process Date/Time: 2018-04-02 00:00:00

Process Step 5

CC ID: 792170
Description:

Utilizing the Populated Places layer from - U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics's (BTS's) National Transportation Atlas Database (NTAD). Feature class was Projected into World Mercator Layer contained many points so to make it easier to work with any point that was farther than 50 miles from the SLA (Submerged Land Act, BOEM layer) was removed to make processing easier-resulting layer was called Populated_PlacesCoastalCities.

Process Date/Time: 2018-04-03 00:00:00

Process Step 6

CC ID: 792171
Description:

Merge Census2010TerritoryPoints & each of the 4 removed layers into one layer which I called PLACE. If any areas appeared too sparse after this was completed I was able to return to the PP_CCHUGE, PP_CCBIG, PP_CCMED, & PP_CCTINY layers to see if there is a city to add, if no city existed look in the Place_2010 Census centroid point file. Utilizing the Raster Navigational Charts from NOAA as a base map systematically start at Alaska & worked down around the coastline removing/deleting, using the editor tool, any extraneous cites from the center of land out to the coastline from smallest to largest, assuring that cites that existed on the RNC remained, or a city with the largest population near the coast & close to an RNC designated city remained.

Process Date/Time: 2018-04-04 00:00:00

Process Step 7

CC ID: 792172
Description:

You are left with cities of differing sizes guaranteed to be 5 miles apart, but bunching will still occur with cities within the same layer. For all areas where the coastline had a dense population of larger cites to utilize I deleted smaller sized inland cities (as we originally had a 50 mile buffer inland & moving forward only want coastal cities)
