The Zip Code Business Pattern Data from the Census Bureau would be one place to look: census.gov/econ/cbp

Degrees are part of a modified Sexagesimal (base 60) number system. Even though there are 360 degrees in a circle, 360 is 6 x 60. See also Coordinate Conversion: Decimal Degree to Deg-Min-Sec of lat/long Coordinates In terms of fundamental physical units, mass, length and time, angles are actually unitless because they are derived from ratios of lengths: ...

Added per request... Have you tried census.gov, and/or American Fact Finder? You generally have to get the data table and join it to the geographic file (block, tract, group, etc). Not all data is available at all levels, but unless it's a very sparsely inhabited area, I imagine they're all smaller than county level.

The Datameet github repo for maps has the 640 districts as per the 2011 census, which are available under a Creative Commons Attribution-ShareAlike 2.5 India license, in shapefile format. I don't know where you got the figure of 671, but according to census of India, there were 640 districts in 2011. (see page 14 of the Administrative Atlas)

There are many more sources of shapefiles than geojson, and you can easily convert shp to geojson with ogr2ogr. For example, you can download the shapefile for the "Ecoregions of the World" from here, then convert BIOME 13 (deserts) to geojson with ogr2ogr: ogr2ogr -f GeoJSON -lco -sql "SELECT * FROM wwf_terr_ecos WHERE BIOME = 13" output.json ...

This might be better as a wiki. In British Columbia, civic addressing is maintained by local governments (ie, municipalities and regional districts). Depending on what your use is for the data, they can often be obtained by simple data requests directly to those local governments if it's not publicly accessible already. The data you get might not be under ...

I think you're looking for the Postal Conversion Code File. Other companies do provide their own version of it though with other socioeconomic data.

My manager found the Smart Location Database by the EPA and it includes, among other things, gross employment density (jobs per acre) on unprotected land. It breaks it up by categories like Retail, Office, Industrial, etc. instead of the BLS categories in my question. I still plan to do more searching with the suggestions above and will let you know how ...

thanks all for the reply, @ John -- i first started searching on the local municipal corporation websites and got some of the maps in jpeg format in which ward boundaries were marked, but not all of the municipal boundaries provide these maps.I have found ward map jpeg files for some cities of Andhra Pradesh, India. Actually i need ward boundaries of all ...

Take a look at the Global Administrative Areas dataset at http://www.gadm.org, it contains at least the boundaries, though I am not so sure about the territorial waters part

Depending on what you need the data for, the following links may or may not be helpful. You may find useful data from the National River Flow Archive (NRFA), part of the Centre for Ecology & Hydrology: http://www.ceh.ac.uk/data/nrfa/ As far as I can tell they do not have GIS formats available to download. This website, made by Shoothill, maps river ...

JPG and PNG are not spatially aware formats, meaning their location/georeferencing information is not stored within the file itself. That requires an accompanying World file that stores such information so the image can be georeferenced. As GISGe suggested, the GeoTIFF format is available and does include georeferencing information, so it would be suggested ...

For temperature and precipitation, you can use the Worldclim dataset, but it does not include cloud cover.

I have been using NHGIS in my teaching as an alternative to Factfinder. It has a data finder that lets you filter for years and topics and select the appropriate shapefiles (more information here). The unique identifier to join shapefiles with tables is GISJOIN and instructions are here. Registration is free.

The demographic profile tables (DP02, DP03, DP04, DP05) are extracts from the more detailed ones, so I'm not sure they would be available on the ftp server (since all the data is there in the full tables by default). Another option would be to look at the Missouri Census Data Center's Uexplore/Dexter tools here: ...

The Census Bureau also publishes csv files for tracts and many other geographies that contain the population centroid (aka Centers of Population) for each feature. In one download you'd have the Tract ID numbers, the 2010 Population, and the population centroid in Long / Lat (NAD 83) for each feature: http://www.census.gov/geo/reference/centersofpop.html

The American Factfinder is going to be the most comprehensive source for downloading current US Census data. It's also going to include the identifiers that you need to join the attributes to the census geography by default; you can download the geography files from the Census TIGER shapefiles site. To use the Factfinder, select the Advanced Search option. ...

American Fact Finder data (tabular) needs to be joined to TIGER data. The TIGER data delineates the boundaries you are working with, be it State, County, MCD, Census tracts, block groups, blocks, etc. Once you have the data joined through a common field you can start examining the relationships between the data.

I know we use a private company called PetroSwell Maps & Data for Texas well and pipeline data. www.petroswell.com, they have pretty good prices and deliver the data really quickly.

Landsat 8 is now being digested by AWS. There is a standard directory structure and the data can be accessed via an http or through the AWS commandline interface. While this not an ftp interface, it will be quite easy to batch download in a scripting language.

One place to look for imagery sources is OpenStreetMap's "editor imagery index", which is basically a machine readable list of imagery provider URLs and extents. https://github.com/osmlab/editor-imagery-index The needs of your project aren't exactly the same as OSM's but there is overlap. In this case, in the Nairobi region it shows Bing and Mapbox ...

Not exactly "high-resolution," but the price is right. Esri's World Imagery map service presents satellite imagery for the world and high-resolution imagery for the United States and other areas around the world.
