I've located two sites that display the data that I'm looking for, but both lack exporting functions.

OASIS NYC and maps.nyc/gov

Otherwise I can't locate this data anywhere in a format I can use in QGIS.

Anyone have any suggestions?

Otherwise, is there a simple way to go from an image with points to creating a shapefile with the proper coordinates?

  • Welcome to GIS SE! One of our protocols which can take a little getting used to is that there should be only one question per Question. Consequently, I recommend that you use the edit button beneath your Question to remove your second question, and then research/ask it separately.

The New York State Department of Environmental Conservation has the information for all combined sewer outflows on their FTP site however their file you're looking for (NYSCSO.zip) doesn't have a prj file associated with it. It should be in NYS State Plane, but none of them (EPSG 2260 - 2263) seem to work. You'll have to play with the projections to find the right one, but it will be far better than trying to georectify some png file.

The other option is to try and hack the back end of the website. This isn't ideal because it looks like the actual data is being served up on the back end instead of being provided to the browser in a geoJSON, but it might be doable depending on how websavvy you are.

Good luck.

UPDATE

It's EPSG 26918. The points should line up with the coastline. You can just select the points for NYC and create your own shapefile from there.

UPDATE

You can download the zip file from here. Hope that helps.

UPDATE

I also found this site, which in addition to having the locations also has current rainfall amounts.
