This is a deceptive title. The maps presented are interesting, and the article touches on related points of where infrastructure is located, and where people live, but aside from noting that parts of the deep ocean have not been mapped in d

The about page talks a bit about the sources. Everything comes from the latest 5-year American Community Survey (ACS), which is part of the Census Bureau's data collection. Data from that survey is in some sense an average over the yea

Self funding. Yes, the government should provide something like this directly, but they are not very good at building web sites that are easy to use.

We ended up using some random C library to parse the shapefiles into an easier to read text format of our own design, and then pulling them into packed binary files with an external index that we memory map in the code to maximize the speed

Thanks. We may build an API at some point, but it is not to do with the TOS. The raw data is so big (and we use memory mapped files, not a DB) that it is a pain from an infrastructure perspective to have available on a web box.

I'm one of the developers. This site is all about making public data about places more accessible. We have pages all the way from the national level all the way down to individual city blocks, and everything in between. The data itself

Can somebody on the IE team comment on when specific SVG features will be added? I am interested in using a <use> tag with a xlink:href to an element in a different SVG file. This is part of the SVG spec and works in the latest versio

(I'm one of the devs.) Thanks! Yes, adding user-controlled edge blur is a great idea. So much to do, so little time.

(I'm one of the devs.) Thanks for the link! Real time is a pretty big constraint, and the input for those results is a much more complete labeling than we expect (only 22 to 44 pixels around the ground truth boundary are left uncertain). B

You can make the brush size smaller by zooming in.

Thanks!

You can get a smaller brush by zooming in using the mouse wheel. That way the brush is always an appropriate size (small when you are zoomed in for detail work, and large when you are zoomed out for the broad strokes).

(I'm one of the devs.) Regarding the segmentation phase, we were not satisfied with any existing algorithms because we wanted the tool to be as real-time as possible (for up to 4 megapixel images), so we rolled our own segmentation algorith

Not everyone is a web developer :). There are tons of sources of geo-tagged data where the time zone is useful. For exsmple, we built it to annotate a database of weather stations with the correct tz ids.

Thanks for your thoughts. Agree with almost all your points. This just is a tiny side project and we've not gotten around to fine tuning the offering. And if the 4sq guy's boss lets him spend time to open-source their attempt at this, I don

Are you implying that web page design skills and icon choices are a good predictor of a coder's ability to write a blazing fast spatial index? This library solves a hard problem very well. The web design is as it is because we threw the web

by jrd79 15y ago
Can't imagine it will cost you less to develop in house in terms of salaried engineering hours, and you probably won't get close to AskGeo in terms of performance. A fast spatial index is non trivial. Classic case of not properly valuing th

Actually, the Russian time zone change only changes the rules of those time zoned, not the geographical extent of them. Since we just return a tz id, users can just use an updated tz database (any up-to-date Linux system has this) to get th

I am the developer. Yes, please contact us if your usage is low but you are commercial. I'm sure we can figure something out that is fair.

We offer that as a Java library and associated data file. You can read about it on the web page.

Sounds like a great idea. I have several web sites and I would definitely have given this a try when trying to find names for those. And I'll give it a try for the next one. But I have a couple questions that I didn't find answers for in

We have put together a map/chart combo to visualize the data that underlies climate research. You can filter the stations based on several parameters, and get both a visualization as well as a computed rate-of-change. Tool: http://weathers

Thank you for the suggestion (and for all your comments)! We really appreciate the feedback. Travel is a direction that we are very excited about. I've added your comment to our ticket tracker, so we'll revisit it when we get the travel

It is definitely a blip. The reason it doesn't appear in all the zoom levels is that the four-hourly zoom level takes the average temperature of the hourly data over the four-hour period. Once you go up to the daily zoom level we switch to

Great point. We are 100% on board with this (in fact, your Hawaii use case is one of the actual reasons why we started this project)! As a two-man shop we had to prioritize and decided to create the geek tool first and then start expandin
