iKatastr2  update je na  App Store !  Diky všem, kteří jej používají  a podporují tento projekt. Těší mě, že se aplikace hojně používá – a to byl také hlavní důvod aktualizace aplikace.

Tento update  je  udržovací – obsahuje rekompilaci na nejnovější iOS a zároveň stále podporuje iOS od verze 6.   Byla aktualizovaná knihovna Google Maps SDK a opraveny drobné chybky.  Můžete zde napsat své názory, komentáře a ještě lépe přímo na App Store iKatastr2 ocenit – to je jediná měna, kterou  můžete za aplikaci, která je zdarma “zaplatit” – a věřte, že každý pozitivní ohlas dodává vývojáři palivo, smysl a chuť v tom pokračovat a třeba i něčím novým překvapit :)

Hybrid vs Native

~    ∫ ∪ ∧∴ ∋ ∈ ⊇ ∧ ~ Leave a comment

It has been a while since my iOS native development. Just came across this report on the subject of native vs hybrid : Native vs Hybrid . Interestingly enough I have expected clear recommendation for hybrid as today devices are more capable of handling rich HTML/JavaScript content and iOS native bridges enable nice integrations with these two worlds.

Google Trends – close to reality ?

or no ? … how to explain this picture ? iKatastr was indeed attempt to introduce new term for accessing cadastral data in Czech Republic, and it launched on iOS, Android and web 5 years ago, no public advertising, no ads at all…  Anyway I like this picture, and it is kind of surprising that GISCloud nor mangomap doesn’t enjoy the same level of trending according to Google Trends. I think reality is different

..let’s look on another measure – site visits using simlarweb.com

Looks like Google Trends takes into consideration # of visits and is more weighted than media coverage ? Or does the mobile presence of app iKatastr adds so much ‘ads’ to the final chart  ?

 

Joy of Open Source

*** update IV/2017:  from comment below, check this great raster plug-in  from Victor Veralde Gutiérrez too: https://github.com/IHCantabria/Leaflet.CanvasLayer.Field/  ***

I have got great, absolutely amazing  joy today from my own open source experiment. In 2014, nearly 2 years ago,  I have published on GitHub (gist)  L.CanvasOverlay a small class  to handle generic drawing on top of Leaflet, I was thinking let’s try to  contribute back to the open source with this little snippet –  I thought would be useful so I have added little description. Original blog post here: https://blog.sumbera.com/2014/04/20/leaflet-canvas/

After few months later I found it is used on http://windyty.com   one of the best 2015 geo-visualization with huge popularity. It is a small part of this great app, but makes me feel so good like I am part of it, I am looking on something where is my small piece, small share…meaning of the effort, sense of publishing and open sourcing.

And today I have got echo it is used also in Marine National Facility here: http://www.cmar.csiro.au/data/underway.test/

This makes me so happy … and just came across this quote : “Revenue is a lagging indicator, usage is a leading indicator,” can’t remember, who just said that ? :)
