On 7/10/2022 I posted to this list about an effort to create a comprehensive index of all topographic maps published in the USA. I am still a long way from that goal. I do have an index of 357,457 records. Some statistics on these records is listed below. I suspect every library on this list has maps not listed in this index. Anyway, if anybody wants the records for their state, I can supply a CSV file that can be opened by Excel. Records per state: AK - 17130 AL - 5680 AR - 5240 AS - 9 AZ - 11076 AZ NM - 6 AZ NV - 1 AZ NV CA - 1 CA - 23251 CA NV - 5 CO - 12399 CO KS - 3 CO KS OK - 2 CO UT - 4 CT - 1341 DC - 52 DE - 404 FL - 7539 FM - 19 GA - 5605 GU - 9 HI - 1000 IA - 5842 ID - 8616 ID MT - 4 ID OR - 2 ID WY - 2 IL - 6323 IN - 4581 KS - 8712 KY - 4878 LA - 6170 MA - 3108 MD - 2382 ME - 5323 MI - 7112 MN - 8676 MO - 7461 MO AR - 1 MO KS - 2 MP - 9 MS - 4458 MT - 14688 MT ID - 2 MT WY - 3 NC - 6022 ND - 6434 NE - 6733 NH - 1532 NJ - 1677 NM - 10521 NM TX - 2 NV - 9150 NV AZ - 1 NV CA - 7 NV ID - 1 NV UT - 4 NV UT ID - 1 NY - 9030 OH - 5751 OK - 6876 ON - 12 OR - 10156 PA - 8167 PR - 810 PW - 12 QC - 23 RI - 395 SC - 2956 SD - 6634 TN - 5707 TX - 22978 TX MX06 - 1 UT - 8778 UT AZ - 17 UT CO - 14 UT CO WY - 2 UT ID - 4 VA - 6617 VI - 57 VT - 1545 WA - 8905 WA OR - 2 WI - 7400 WV - 3469 WY - 9921 WY SD MT - 2 Records per map scale: 10000 - 77 12000 - 1 20000 - 474 21120 - 19 24000 - 294493 25000 - 9627 30000 - 276 31680 - 3944 48000 - 1120 50000 - 277 62500 - 28380 63360 - 7064 96000 - 43 100000 - 3016 125000 - 4445 126700 - 1 127000 - 1 192000 - 2 250000 - 4197 The header row across the top (columns): Series Version Cell ID Map Name Primary State Scale Date On Map Imprint Year Woodland Tint Visual Version Number Photo Inspection Year Photo Revision Year Aerial Photo Year Edit Year Field Check Year Survey Year Datum Projection Advance Preliminary Provisional Interim Planimetric Special Printing Special Map Shaded Relief Orthophoto Pub USGS Pub Army Corps Eng Pub Army Map Pub Forest Serv Pub Military Other Pub Reclamation Pub War Dept Pub Bur Land Mgmt Pub Natl Park Serv Pub Indian Affairs Pub EPA Pub Tenn Valley Auth Pub US Commerce Keywords Map Language Scanner Resolution Cell Name Primary State Name N Lat W Long S Lat E Long Link to HTMC Metadata Download GeoPDF View FGDC Metadata XML View Thumbnail Image Scan ID GDA Item ID Create Date Byte Count Grid Size Download Product S3 View Thumbnail Image S3 NRN NSN Mike Flannigan Houston, TX On 12/13/23 23:26, Brendan Whyte wrote: > Hi all, > > After years of procrastination, I have begun indexing our US 24k > series (very incomplete... we stopped collecting these when an > exchange programme with USGS ceased 20-30 years ago) > I have made an overall US map showing which states have been properly > indexed to date, and attached this to our catalogue record > https://catalogue.nla.gov.au/catalog/6855508, along with coloured-in > indexes of each of the 19 smallest states. > > The plan is to work my way through the remaining 30 states in 2024.... > wish me luck! > > Please let me have any feedback on what I have done so far. > (once you've opened the US index, click 'browse this collection' in > the breadcrumbs to see the individual state indexes) > > What have others done in the way of online indexes for the series? > We have never even considered cataloguing the sheets > individually... but I guess we could have done individual records (and > indexes) for each state set, and linked them with an overall parent > series record similar to our existing record... but that's > nevertheless more work for the cataloguers. > > Compliments and criticism most welcome before I embark any deeper into > this project... > > Merry Christmas! > > Brendan Whyte > National Library of Australia > > > > > > > >
