Cool question and nice map... I did a reverse image search and found a blog post from 2011, the same year as the map's creation, which has lots of technical details: https://www.digitalcommonwealth.org/search/commonwealth:7h149v32x Title: 1630 shoreline Creator: Metropolitan Planning Organization (Mass.). Central Transportation Planning Staff. ...

I assume you've already found averages at Current Employment Statistics, FactFinder, or the American Time-Use Survey. I don't see any percentiles there. I don't know of any ready-made tables from BLS or Census that include percentiles for hours worked, so unfortunately you will probably need to create your own tabulation using microdata from CPS PUMS or ...

Those are the HU-2 (2-digit Hydrologic Units) boundaries from the national Watershed Boundary Dataset (WBD). Sometimes you'll see them referred to as HUC-2 instead of HU-2 (HUC = Hydrologic Unit Code). It should be possible to download this data for the entire continental US as a single dataset. However... It's very easy to get the metadata for this ...

Detailed spatial data seems to require a CNDDB subscription. You could put together quad level data (USGS 7.5 minute topographic quads) with this publicly available endpoint that lets you query what species are in a particular quad. For example, for quad 3811957: https://apps.wildlife.ca.gov/bios/rest/Cnddb.ashx?o=cnddbQuickView&p=QuadSpecies&q=...

The data exists but it is unlikely to be open. From the U.S. Census Bureau (recall there is a crosswalk between SIC and NAICS codes) Can I get a NAICS code or other statistical data for a specific company? Title 13, U.S. Code, Section 9 (a) prohibits the U.S. Census Bureau from releasing information on a specific business including NAICS ...

Thanks to everyone who gave it a try, both those who confirmed the problem, and those who have been more successful. I have tried it this morning from home (as opposed to work, again in Belgium), and everything worked just fine. I wonder what caused the problem. I sent them an email yesterday explaining the issue. Maybe they put together a quick fix. I ...

You asked for a shapefile of the Boston harbor shoreline for 1630. However, what seems to be available from that era is mostly raster images of maps. So you will probably need to digitize the shoreline yourself from a georeferenced image. In addition to the original map (provided in philshem's answer), there are many different sources of historical maps. ...

If you have a handful of stadiums and arenas only, then you might find a list online that suffices. For example, from Wikipedia global or US only. If you need wider coverage, and also for many types of buildings, consider the following two options: Option 1: Wikidata, with as an example some variation of arena (Q641226) and maximum capacity (P1083) ...

This is not an answer. If you visit https://sdmdataaccess.sc.egov.usda.gov/QueryHelp.aspx and download the "Table Column Descriptions Report (741K)" PDF, you will get a list of all tables (and column names) for your data. You can then go to https://sdmdataaccess.sc.egov.usda.gov/Query.aspx and make queries like SELECT * FROM chaashto. You will have to ...

Thanks for submitting your questions. I forwarded your questions to our helpdesk and received the following responses. I hope you find them helpful. What is the best way to determine the concrete subset percentage [of TIV students] used for a given measure? Is it a "cohort" column, like Number of students in the family income cohort? For some metrics ...

This question on GIS Stackexchange provides a good overview of why this is not as simple a request as you might think. Zip codes are created, maintained and updated frequently by the USPS (US Postal Service), not the census bureau. Their databases are not open or free. However, if your previous dataset is from the 2010 Census, you probably don't actually ...

If you are by any chances affiliated to a Canadian university you get free access to DMTI POI data that includes all that information for Canada. All of this is located in the Scholar GeoPortal repository at http://geo2.scholarsportal.info/ For the US there is a similar company called SimplyAnalytics that also has free access through many Canadian ...

I'd read the Wikipedia article, but seeing the chart blown up in philshem's answer sent me looking for the data source, which luckily is linked in the image attribution. Renewables and emissions reports on CAISO's market operations site includes a *.txt file with hourly generation data by day for all renewable energy sources in the state, going back to 4/...

Exact hourly solar/PV production will be with the grid operator, and if you have an academic/NGO credentials, maybe they can make you a 1-time export. I don't know California, but I've worked in the energy sector and because there is energy trading between stakeholders, no one is really eager to make open data. The grid operator may not even have total ...

There is a program designed to prevent accidental destruction of buried utilities, which has made the effort to provide data about underground utilities to the public. This is the "Call before you dig" (http://call811.com/) program. Each state has it's own version of the "call before you dig" program. This free program will send a person out to a planned dig ...

The LEHD program of the Census Bureau publishes crosswalks which map every Census Block to a number of other geography types, including ZCTA and CBSA. You could download one of these crosswalks, filter out just the columns for ZCTA and CBSA, and then take the unique rows -- then for each ZCTA, you would see which CBSA it is in. Note, however, that a few ...
