Indicatrix mapper Plugin icon

(13) votes 

The plugin introduces the tiss-indicatrix (quick-and-dirty Tissot-indicatrix realization) term by Szabó and Wirth, 2015. The tiss-indicatrix uses constant radius ellipsoidal caps (calculated by Vincenty's formula) instead of the original infinitesimal small Tissot circles. These caps are able to transform on the fly from a reference ellipsoid to a selected project coordinate reference system. The user can study the distortions of the caps in a blink, such conclusions can be drawn as the projection is conformal or equal-area.

The extent and resolution of the caps and the graticule are able to define. The segments refers to the preciseness of the geometrical elements. The radius parameter means the magnitude of projecting caps, it can be given in kilometer or degree dimension. In case of adding more layers untick the 'Simplify geometry' option at the Rendering tab of layer properties. QGIS contains approximately 2700 categorized projections, you can test the effects of the projections for your Country as well. Check the homepage or look after 'QGIS Map Projections' tutorial video by BME FMT on YouTube for further detail.
