Qt and JavaScript: A Perfect Match for Native App Development

via Qt and JavaScript: A Perfect Match for Native App Development | ArcGIS Blog.

There are many developer platforms and languages to choose from if you’re planning on building native cross-platform apps. In this article, we’ll take a look at a highly popular one, yet one that you wouldn’t immediately think of for pure native development, and that is JavaScript.

JavaScript , while best known as a dynamic programming language used for extending web browser capabilities and web-based scripting, is also a powerful language for building behavior into native, non browser-based applications, thanks to the The Qt Company’s QML API and Esri’s ArcGIS Runtime SDK for Qt that extends it.

Using OneMap Address Search in iOS App

In this tutorial, we are going to implement the address search feature using OneMap REST API. If you want to know more about OneMap, please visit to OneMap API Help page. We will continue our tutorial from my post how to add OneMap to iOS App, in which I’ve shown how to use ArcGIS iOS SDK […]


Using JavaScript to Create Geospatial and Advanced Maps

via Using JavaScript to Create Geospatial and Advanced Maps.

Geospatial Information Systems (GIS) is an area of cartography and information technology concerned with the storage, manipulation, analysis, and presentation of geographic and spatial data. You are probably most familiar with GIS services that produce dynamic, two-dimensional tile maps which have been prominent on the web since the days of MapQuest.

Until recently, developing geospatial apps beyond a 2D map required a comprehensive GIS service such as ArcGIS, Nokia Here, or Google Maps. While these APIs are powerful, they are also expensive, onerous to learn, and lock the map developer to a single solution. Fortunately, there are now a wealth of useful, open source JavaScript tools for handling advanced cartography and geospatial analysis.

In this article, I’ll examine how to implement GIS techniques with JavaScript and HTML, focusing on lightweight tools for specific tasks. Many of the tools I’ll cover are based on services such as Mapbox, CloudMade, and MapZen, but these are all modular libraries that can be added as packages to Node.js or used for analysis in a web browser.

Jasmine – clicking on an arcgis map with Javascript

via Jasmine – clicking on an arcgis map with javascript | Software,Technology and electronic music.

It is a short one in the middle of the work so I will be very general.

As you know I am doing quite a lot of ESRI ArcGIS Javascript development.

So recently I am backing that all up with the karma/jasmine combination for a quality application development (TDD of course, but thats a different topic)

So I had a problem at some point

Sly Mapping with Niklas

via GeoDev Germany: Sly Mapping with Niklas | GeoNet.

The weather situation over the past two days Germany was ruled by Niklas, one of the strongest storms in recent years. And while the country, and especially the web , are still busy cleaning up, let’s look at a map of what was actually going on these two days:

With the help of two CSV tables, downloaded from the website of the German Weather Service , a Webmap on ArcGIS Online is quite fix created. Each table gives a layer for each of the two days. Both map layers were then published Feature Service as a hosted and publicly released.

The Services may now be consumed from anywhere, and using the new features in the ArcGIS API for JavaScript generates small application ” storm Niklas Germany “beautiful views of the weather arrived at the measuring stations.
