Re: Getting started with geographical coordinates

Thanks. Can’t think of a better place to be locked in! I’m sure Google thinks of what3words as a competitor, but also I suspect w3w keeps their mapping very close to their chest as a proprietary asset. Alex . Sent from my iPad > On 7 Apr 2020, at 16:58, Ben Rubinstein via use-livecode >

Re: Getting started with geographical coordinates

Thanks for everyone who has helped with this so far. I have now looked at and tested LC scripts for three different functions for finding the distance - I left one well-known one out (Vincenty) as it’s very complex (it even includes iteration) and I think not justified by what I’m trying to do.

Re: Getting started with geographical coordinates

I’ve been trying these formulae out, and I’ve been using the info on https://www.movable-type.co.uk/scripts/latlong.html - for my purposes (distances from say 100 metres to up to a few kilometers) I think this works as well as haversine, but maybe not for every kind of measurement. The function

Re: Getting started with geographical coordinates

I see where people get confused. When we talk about dimensions, for most people the “Physical” in “Physical Dimensions” is implied, just like when Dad says, “Hand me the map”, what he really means is, “Hand me the plastic coated street and highway map of the state of California that we just

[ALERT: Waxing Philosophical] I wholeheartedly agree. These people UNDERSTOOD Mathematics. This was a big problem for me as a child. I failed 6th grade math and had to go to summer school to pass, partly because I was lazy and wouldn’t do my home work, but also because I would sit in class and

RE: Getting started with geographical coordinates

A friend of mine turned me on to this 10 years ago. This is the Haversine formula. It assumes that the earth is sphere and is not very accurate for very small distances. I have not tried to use the Vincenty's formula that does better. For general purposes the HF should be sufficient. Just give me

Re: Getting started with geographical coordinates

Most of the mobileSomething are wrappers around the system functions so you can learn a lot by reading the ios developer documentation as most of the functions started there. And reading the docs I can see that you probably get a CLLocationCoordinate2D from the system and that is in turn two

Re: Getting started with geographical coordinates

Graham, You get back lat and long in degrees and fractions of degrees, as a decimal numeral. For instance, I get latitude: 40.248676 and longitude: -111.651062, and for good measure altitude in meters at 1398.380493. Wow, now you all know exactly where I am! Devin > On Apr 3, 2020, at 1:49
