Despite the advantages of 3D rendering and the trend of migrating applications to web browsers, there are various obstacles that developers have to face and overcome. The steep learning curve, the insufficient cross-platform support, and the difficulty of maintaining make WebGL a beast to work with. In a way, we want to keep the obstacles away from web developers, so INT provides Carnac3D, a subset of GeoToolkit, as an industry-leading graphical product.
Programming is an activity that requires a special set of cognitive skills. While the industry has developed processes and tools to ensure the quality of software artifacts, the act of writing code is a craft in itself. Developers pride themselves on the “big picture” results they achieve, but the activity of programming is definitely a humbling experience: it’s easy to introduce bugs, and regardless of whether I catch them right away or later in the pipeline, I hate to be reminded I am inherently flawed and have introduced a defect. For this article, I will focus on simple methods to avoid bugs, not before or after you write code, but while you write that code.
In this post we consider how to display data, which includes geometry and nonspatial information like names from ArcGIS ESRI services using the GeoToolkit.JS Map Widget and WMTS data from OpenStreetMap.
