Yeesian, I took the time to read the entire presentation. It does look very 
promising!  Thanks for such work, I'll certainly keep an eye on it.

Yeesian, this looks really promising! It will be great to follow the 
progress of this.

@Yeesian Ng : Thanks! Looks like my typical work day :)

@cdm : Subscribed to julia-geo. Will be useful!

@others : Thanks! We have lots of useful information for anyone reading 
this thread. :)

It is based on slow work-in-progress, but I have slides 
 (and notebook 
)
 
for a talk I'm giving later today on geospatial processing in julia. They 
give some sense of what the API of plotting a map through 
https://github.com/tbreloff/Plots.jl via 
https://github.com/yeesian/GeoDataFrames.jl might look like in the future.

Maybe PlotlyJS.jl can provide the mapping functionality you need? It allows you 
to create chloropleth maps as well as scatter plots (line, bubble, or dots) on 
top of maps.

[Kaj Wiik]

In fact I was going to suggest you to register Luxor,jl but forgot it... 
Very convenient layer on top of Cairo.jl. 

It is really simple to work with rasterized maps, just calculate proper 
transform matrices and you can switch between normalized, image and UTM 
coordinates with setmatrix().
The new docs are very good!

Cheers!

Kaj

@Kaj Cool, I didn't know anyone was using Luxor.jl — perhaps I shouldn't have 
made so many changes recently... :)

Perfect, thanks!

Geodesy.jl now has a native port of libgeographics UTM conversion code - 
you might possibly find that convenient.

Wow, that's interesting! Thanks for pointing that out!

You can open esri shapefiles with shapefiles.jl. There is a plotting function 
for shapefiles in plotrecipes.jl. You can layer shapefiles to create vector 
maps. I am happy to help out if you want to use this.

[julia-users] Re: Maps in Julia?

[daycaster]

@kaj I had no idea anyone was using that. I must be more careful with updates!

[julia-users] Re: Maps in Julia?

['Philippe Roy' via julia-users]

@ J Luis : The GMT examples are impressive. I do like the look of the maps. 
I'll keep an eye on the GMT.jl package.

@ Kaj : Nice map too! 

from all your answers, I see that it's more than possible to do maps in 
Julia. I'll try your suggestions and see what is more convenient for me.

Thanks again!

To give you guys an idea, these are all GMT mapping examples

[Chris]

The PyCall README is quite comprehensive, and the Basemap documentation has 
some good examples. Otherwise, I basically just used trial and error until 
things worked the way I expected -- you get the hang of it eventually.

Hi!

I have done some bits of code to make maps and calculate results for 
Finnish powered paragliding championships over the years, like this:
http://movasuunnistus.dy.fi/viitasaari2016/tulokset/suunnistus-viitasaari-2016-timlander.pdf

I use Cairo.jl via Luxor.jl and transform geographic coordinates (GNSS 
logger lat, lon) to UTM (cartesian, unit = metre) by calling libgeographic. 
The base maps are from open rasterized tiles from the Finnish National Land 
survey. 

Quite easy really, if there is need I could tidy up the code for a 
module...at least the libgeographic bit. The rest are quite specific to 
Finland.

I guess using PyCall could work indeed. Is there some kind of tutorial 
about this matter (i.e. Basemap in Julia through pyCall) that you know of? 
I'm not really proficient in Julia and Python now (hoping to learn though!).

Thanks!

Hi,

The GMT.jl  is still under development, 
namely it's waiting for the next (this month) release of GMT5.3, but it 
already gives you access to one of most powerful Mapping Tools.

This doesn't specifically answer your question, but I have used Basemap via 
PyCall without too much trouble in the past.
