Abstract
Arctic Web Map (AWM) is an Arctic-specific web mapping tool allowing researchers and developers to customize map projections for scientifically accurate visualization and analysis, a function that is critical for arctic research but not easy to do with existing web mapping platforms. It provides a visually appealing tool for education and outreach to a wider audience. Arctic Web Map has two components: An Arctic-focused tile server offering mapping tiles, and a Leaflet-based client library. By providing tiles in multiple Arctic projections, data can be more accurately visualized compared to most Mercator projected map tiles. The open source client library, PolarMap.js, is designed to be easy to use and easy to extend. It does this by providing a simple wrapper for building a typical Leaflet map, and also by providing base classes that can be customized to build a web map for your specific situation. This presentation will present and demonstrate the AWM and PolarMap.js and some real-world applications will also be discussed and demonstrated.

Lecture/Conference
I thank you for the introduction you in the back
so my apologies if I can answer your questions and act I did work on this project I was asked a week ago to come and present this 1 as well so I have 2 presentations here and the other 1 I have some say in because I actually do work in that company also this this project the arctic web map is basically a project where the we we don't we live in Canada we live in northern regions of there's no good web map projections for us in our there are areas are a vast land masses up in there it up in the north so they came up with a an idea to create a simple map projection package and so if you look at his map
we were looking at wildfires but but where are the wildfires working the it's a very it's kind of a not a very good picture image I know that but the the point of this slide is to say
well of the the data is hard to see right it's distorted exaggerated and you really can't making measurements of of your data because this is in northern Canada this isn't and and none of a territory so as a planner you can make good decisions you know where to uh you can make decisions based on distance because you don't use just exaggerated yeah so Weber K. rejection thank
you very much Google and Microsoft are but itself is used for 80 % of world as we see but we still like I said there's a lot of people and a lot of interest especially nowadays that the polar ice caps are melting and especially for Canada a much about for the Scandinavian countries where the law the Arctic sea ways are now open and now this covers conservation practices Gupta watch you know maybe study polar bears and other Arctic kind of animals the 2 we don't really have any decent web kind of projection for web mapping I guess to to display this portrayed as information of the so we say are we still using the
would map based maps for Weber cater or because they have a huge stack uh development stacked lots of tools of lots of the tiles of ready been jet generated so this an ends most of the world and that's all they need to wear special case of in the north we want the same thing to we want that holds STK the whole stack of tools like and stuff to to map our lands in in a more original and the meaningful way so what so what we've done what they've done here what James says done and Steve they've been built up whole cell libraries based on OpenStreetMap of the whole stack of OpenStreetMap the broad of the natural datasets are can number where that came from but it's for the like birth natural data a much where system from but so they seem to the the whole the whole that OSM where you were rendered the tiles of 10 levels then after that it's going be on the fly rendering so there's
no this is the way the 6 CPs cheek zones in the north and there are all defined by these codes so
the 6 projections that say no matter where you're at you know with uh if you're on the other side and Scandinavia Russia he can pick 1 of these and it's a top down you can view it's in your in your browser I so you and this I haven't
actually ask you what this means I think what he means is you want to have engage these northern countries are these northern uh villages up and in northern Canada to start it increasing the the the quality of the mass of the have of the so the mapping parties I hope he sends me because I want I wanna go to Northwest Territories and and and none of that I've never been there too but I hope a sense me so if we
go to a little case study this is how the ranking and what is a place in northern Canada the it's right here and this however
cater this is what it's the fur trade to to look like it's not used for map to to to display the same area now I tried to do a quick get overly we'll see what happens so you can see the distortions between the 2 right so this is polar projection and this is just lover so you know to the to the untrained eye this may be good enough but for someone who really cares but just a little bit more it the point wanted to try your data in the in the in the right projection yeah and then in in similarly but if we
go this is a complete of map that that that reduction presented to the Canadian government what this has is weather stations around the northern northern regions the
so look here this is a weather station I'm not sure who owns this this is Russia France so that's the weather station and we can see you
very nice map and we can also see all temperature
data wind speed all that kind of stuff so just from a
single the map gesture we can see exactly the 3 year all the Arctic relevant arctic regions and in a in a in a different way I think this is knowledge and is hard it's hard to it's hard
to look from the top down like that is not used to that area so there's a temperatures and stuff like
that so it's so I
the people was I so what we we've open-source this and it's and is it's it's available at gate of the bucket and get help it's also already a plug-in in flat so it's right there if you go to the web page and I'm not a JavaScript it brought job would strip developers how many joules her developers Arthur OK you guys a better than me because a can be tested by bonded told that it's too breezy use this is the this is the slide that the presented to rivers and so I don't know that looks pretty using may have at that so do you have any questions the all have basically a please make any technical questions and if you do have the questions of these are the people actually work on it so you can write down their e-mail addresses and you know them directly OK the thank you very much if
