GMaVis is an external domain-specific language (DSL) that facilitates the creation of visualization of geospatial information by using multi-core architectures to process data in parallel. Its compiler abstracts complexities from the whole visualization creation process, even in the data pre-processing phase. Also, it allows domain users with low-level knowledge in computer programming to create these visualizations through a high-level description language. These users can easily do it with a few lines of code, using simple declarations and blocks to express visualization details. Currently, GMaVis supports the creation of three types of geospatial visualization: markedmap, clusteredmap and heatmap. GMaVis has a short and simple grammar.
GMaVis' compiler. It is used to recognize GMaVis' code and transform it in a geospatial data visualizations.
Usage: bin/gmavis [-i/--input] <arg> [-o/--output] <arg> [-p/--parallel] <arg>
Example: bin/gmavis -i my_gmavis_code.vis -o out.html
