[GIS] Where to find shapefile basemap for the Indian Ocean

dataindian-ocean

I need to plot point data over a basemap of the Indian Ocean.

Can anyone tell me where I can find such a basemap in shapefile format?

Try Natural Earth, they have ocean data as ESRI Shapefiles, you will however need to split out just the Indian Ocean from the dataset.

[GIS] find a shapefile of zoning for the city of Phoenix and other municipalities

I remember a paper or conference presentation from 3-4 years ago focused on ownership of government data. The discussion was framed in the context of the city of Phoenix invoking homeland security concerns in their refusal to release GIS data, even for classroom use within the city. I can't for the life of me remember the source -- 15 minutes of googling hasn't turned it up either.

Anyway, here's a link to the Maricopa County Planning and Development Department's GIS page. Hope it's of some use to you.

EDIT: So I'll blame the fact that it was late when I posted above but I think I may have blended two distinct memories. The Arizona connection concerns Tempe, not Phoenix, and was discussed in James Fee's Blog. His beef with Tempe was over data cost and accessibility. Perhaps someone else remembers which municipality was restricting access to data by citing flimsy security concerns.
