12 | | * Boundaries and hierarchy: |
13 | | * L0, L1 & L2 are in GADM (done) |
14 | | * L3 |
15 | | * Tiger: http://www.census.gov/cgi-bin/geo/shapefiles2010/layers.cgi |
16 | | * No use for NYC as it puts 1 L3 Borough in each L2 County |
17 | | * Brooklyn: http://geocommons.com/overlays/6090 |
18 | | * NY State civil boundaries: http://gis.ny.gov/gisdata/inventories/details.cfm?DSID=927 \\ |
19 | | "boundaries of incorporated places in New York State (state, counties, cities, towns, villages, and Indian reservations)" \\ |
20 | | (Note ocpyrighted.) |
21 | | * L4 (Zipcodes) -- polygons and parents |
22 | | * NYS |
23 | | * http://gis.ny.gov/gisdata/inventories/details.cfm?DSID=934 |
24 | | * needs parenting to L3s via http://www.health.ny.gov/statistics/cancer/registry/appendix/neighborhoods.htm (done but this is only for NYC) |
25 | | * NJ |
26 | | * http://geocommons.com/overlays/22081 |
27 | | * Could extract hierarchy from one of these: |
28 | | * http://www.brainyzip.com/state/zip_newjersey.html |
29 | | * http://newjersey.hometownlocator.com/zip-codes/counties.cfm |
30 | | * Important zipcode facts: http://www.maponics.com/products/gis-map-data/maps-reports/zip-code-maps/faqs/ |
31 | | * Zipcodes can cross administrative region boundaries. They don't cross state boundaries, but do cross county boundaries. (For the population centers project, when we found a zipcode that spanned admin regions, we partitioned the zipcode -- made one location record for each partition. Names were qualified with the parent region.) |
32 | | * Zipcode regions are not technically polygons but rather groups of addresses. |
33 | | * USPS neither needs nor maintains boundary polygons. |
34 | | * Each zipcode is assigned by USPS to a city, but not by boundary inclusion -- rather, this is by which post office delivers mail to that zipcode. Thus lists of USPS-designated cities cannot be used for the location hierarchy. |
35 | | * Zipcodes have a prefix hierarchy. |
36 | | * http://stevemorse.org/jcal/zip.html |
37 | | * Three-digit zipcode prefixes by state: http://en.wikipedia.org/wiki/List_of_ZIP_code_prefixes |
38 | | * Full hierarchy w/o shapefiles is available from http://www.zip-codes.com/zip-code-database.asp for US$40. They allow looking up data in batches here http://www.zip-codes.com/search.asp, but would need to copy & paste the table part of the page into a file (not the html, just select the rows in the rendered page). Caution: We do not want to use copyrighted or proprietary material w/o the requisite payment or attribution. Could contact them and inquire about temporary use of the information. |
