How gvSIG MapControl works: flow of control

Within gvSIG design, MapControl is one of the core components. Its main responsibility is to allow users to interact with a map of layers (zoom in/out, edit geometries, …). That goal is achieved through two concrete tasks: Route the user actions to the proper tool which will execute it. Manage the drawing of the layers. This […]

Analysis on free software communities (I): a quantitative study on GRASS, gvSIG and QGIS

Disclaimer – this post is part of a serie: I (this one), II, III, IV and V. When selecting an aplication, it’s very common to weight tecnological factors -what the aplication enable us to do?- and economic ones -how money do we need?. And yet, there is a third factor to take into account, the social aspects of the project: the […]

Imagina el siguiente caso: deseas usar una aplicación que es software libre para construir tu propia solución ad-hoc sobre ella. Y lo harás muchas veces para diferentes clientes/productos. ¿Cómo enfocarlo? ¿Construyes tu solución con tus mejoras para ti modificando lo necesario o integras tus mejoras en la versión upstream, en el proyecto original? Si ése […]

I’m not such a fan of comparatives to rank things. But I find them useful to know your pros and cons, or at least to know how the surrounding community perceive your product. While having a coffee today I found this article on gis @ stackexchange: QGIS and gvSIG comparison. Made me happy than 2 out […]
