Re: [Pharo-users] GPS / Longitude / Latitude library

Just for the record. I have a GeoJSON (http://geojson.org/) package at https://github.com/noha/geo-json/ This tackles geo coordinates from yet another angle: How to model a geo position as POI (point of interest) and having a common format for it. And in the meantime geo json is the storage

The data set AoC gave me for problem 3 has 1353 claims. The brute force way is to make your x->(y->count) map and then walk over it counting the number of counts > 1, n := 0. map do: [:row | row do: [:count | count > 1 ifTrue: [n := n+1]]]. On Wed, 5 Dec 2018 at 11:06,

As Dershowitz and Reingold showed in their book "Calendrical Calculations", converting from UTC to several calendars needs latitude, longitude, and elevation. ISO 6709 is the relevant standard: https://en.wikipedia.org/wiki/ISO_6709 On Tue, 4 Dec 2018 at 23:35, Cédrick Béler wrote: >

First, this is a computational geometry problem, as is the second part. If this were a serious problem or had a huge amount of data, we would be looking for a good data structure for holding a collection of rectangles. We might consider quad-trees, k-d-trees, R-trees, ... With such a data

A claim is a claim ID + a rectangle. "If the Elves all proceed with their own plans, none of them will have enough fabric. How many square inches of fabric are within two or more claims?" <--- actual question. units are inches. So, question translates to: "What is the total area of rectangle

Re: [Pharo-users] GPS / Longitude / Latitude library

Interesting. I’m interested with such tools too. I ask students to do gps point collection from mobile (Cordova) and process them in pharo to detect if they enter known places. I wonder if a proper gps point class would be useful. I’d like to record also the precision. Cheers, Cedrick
