A nonzero hundreds digit tells us we’re using longitude, not latitude!
The tens digit gives a position to about 1,000 kilometers. It gives us useful information about what continent or ocean we are on.
The units digit (one decimal degree) gives a position up to 111 kilometers (60 nautical miles, about 69 miles). It can tell us roughly what large state or country we are in.
The first decimal place is worth up to 11.1 km: it can distinguish the position of one large city from a neighboring large city.
The second decimal place is worth up to 1.1 km: it can separate one village from the next.
The third decimal place is worth up to 110 m: it can identify a large agricultural field or institutional campus.
The fourth decimal place is worth up to 11 m: it can identify a parcel of land. It is comparable to the typical accuracy of an uncorrected GPS unit with no interference.
The fifth decimal place is worth up to 1.1 m: it distinguish trees from each other. Accuracy to this level with commercial GPS units can only be achieved with differential correction.
The sixth decimal place is worth up to 0.11 m: you can use this for laying out structures in detail, for designing landscapes, building roads. It should be more than good enough for tracking movements of glaciers and rivers. This can be achieved by taking painstaking measures with GPS, such as differentially corrected GPS.
The seventh decimal place is worth up to 11 mm: this is good for much surveying and is near the limit of what GPS-based techniques can achieve.
The eighth decimal place is worth up to 1.1 mm: this is good for charting motions of tectonic plates and movements of volcanoes. Permanent, corrected, constantly-running GPS base stations might be able to achieve this level of accuracy.
The ninth decimal place is worth up to 110 microns: we are getting into the range of microscopy. For almost any conceivable application with earth positions, this is overkill and will be more precise than the accuracy of any surveying device.
Ten or more decimal places indicates a computer or calculator was used and that no attention was paid to the fact that the extra decimals are useless. Be careful, because unless you are the one reading these numbers off the device, this can indicate low quality processing!
With over 55 million tips in the all-new Foursquare, people have shared a lot of expert advice and insider knowledge. And, we hear from you that one of the most rewarding things about the new app is seeing how many people you’ve helped. Now, when you tap to view your own tips, we show you how many people have seen it.
To see how many people each of your tips has reached, first head to your profile. Then tap on any tip and you’ll see how many people have viewed it, along with likes and saves. We’ll also let you know when a tip of yours has reached a certain milestone, like being seen over 100 times, as well has how many people saw your tips each week.
Your tips have always helped shape people’s experiences. Now you can see just how much of an impact your tips are making.
Since the beginning of Foursquare, tips have helped you find the right places to go and the right things to do when you got there. Over 9 million people have left their best finds and insider knowledge about places on Foursquare; that’s a lot of advice. In the all-new Foursquare, we’ve put tips front and center to make it even easier to share your knowledge.
To leave a tip somewhere, just tap on the blue tip icon at the top right of the screen. We’ll show you a list of the places you’ve visited recently and a search bar to quickly look up places from the past.
Don’t have a tip to share, but still want to share your opinions? You’ll see the option to ‘Quickly rate the places you’ve been’ at the bottom and answer some quick questions so your followers can see what’s good about a place.You’ll be asked questions like, “Is this place good for a quick meal?” or “How are the vegetarian options here?”
With the new Foursquare, sharing your experiences has never been easier. So pay it forward and let the world know what not to miss. Download the all-new Foursquare today.
I really like the new Foursquare. Does a lot of the things I’ve wanted it to do for a long time :)
It’s been less than a day with the new Foursquare, and tastes are already one of the most popular features. In the last 18 hours, you have already added 15 million tastes to profiles globally. And each one helps power better recommendations. After all, everyone’s tastes are different, so why should we get the same search results?
Some of our popular tastes included ‘healthy food’, ‘good for dates’, ‘fried chicken’, and ‘live music’. Some of the more fun ones people chose: ‘banana chocolate chip’, ‘hot wing pizza,’ ‘student discounts,’ ‘early bird menu’, ‘spicy mango,’ and ‘fancy ice cubes’.
Here’s how tastes work. When you first open the new Foursquare, we ask you to tap on some things you like. There are already over 25,000 tastes, and growing every day. They range from ‘pool tables’ to ‘tide pools,’ from ‘used bookstores’ to ‘vintage furniture,’ from ‘cozy’ to ‘romantic.’ Everybody has different tastes, and so everyone should have a different experience in Foursquare.
You can always add more tastes at any time. The more you use the app, the better the recommendations get.
The new Foursquare is always on the lookout for places that match your tastes. When you open the home screen of the app, we show you your tastes nearby. Tap on what you’re craving and find highly-rated places in the area. And, as you look around the app, we highlight your tastes in watermelon color whenever they come up.
With the all-new Foursquare, you don’t have to know what you want. Just say, “where should I go to lunch?” The app knows what you like. Let it lead you to places you’ll love. Get it today.
Love this. So much new data for the team to play with too :)
Since the beginning of Foursquare, tips have been one of our most important and popular features. People have shared a lot of opinions – about off-menu items, the best view, free wifi codes… really about everything. It’s a great way to take your knowledge and pay it forward. Over 9 million people have left tips about their experiences around the world. So, when we started working on the new Foursquare (coming next week!), we wanted to celebrate people who share their expertise, and highlight the great tips they leave.
The result of this is ‘expertise’ you can earn (think of them kind of like badges for leaving great tips). To earn them, you just have to show off your knowledge. When you leave great tips, you make progress. And, the more people like or save them, the faster you’ll earn expertise. You can earn expertise at a type of place (like ‘Dumplings’ or ‘Vintage Shops’) or a neighborhood or city (who doesn’t want to have expertise of Chinatown or SoHo?).
Once you’ve earned an expertise, we both mark your tips as coming from an expert (so the world knows), and make sure more people see them because they’re high quality. And, when you’re looking for great things to do when you’re at a place, you can see which ones come from experts.
Among our early testers of the new Foursquare 8.0, this was one of the most popular features. We’re excited for you to play with it soon in the all-new Foursquare, and for you to show the world what you’re an expert in.
This is one of my favorite features in the new Foursquare app that we’re launching next week (!!).
I have expertise in “East Village”, “Cocktails” and “Kingston, NY” (and like 10 other categories… I’ve left 450+ tips!!)
