gvSIG Desktop

A user-friendly, open source Geographic Information System (GIS)

gvSIG Desktop is an open source, user-friendly, interoperable GIS application designed for capturing, storing, handling, analyzing and deploying any kind of referenced geographic information in order to solve complex management and planning problems. It permits working in a variety of formats, vector and raster files, databases and remote services. There are always available all kinds of tools to analyze and manage your geographic information.

gvSIG Desktop is designed to be an easily extensible solution, allowing  thus continually improving the software application and developing tailor made solutions.

gvSIG Desktop is open source software, published under the GNU / GPL license, this makes its free use, distribution, study and improvement.

Typical tools in a full-fledged desktop GIS client can also be found in gvSIG, among other things:

  • Supported formats: Supported formats can be consulted here: gvSIG 2.0,gvSIG 1.12.
  • Display: zooms, panning, frames, locator
  • Query: information, area and distance measurement, hiperlink.
  • Selection: by point, by rectangle, by polygon, by layer, by polyline, by circle, by buffer zone, alphanumeric search, invert selection, delete selection.
  • Searching: by attribute, by coordinates.
  • Geoprocessing: buffer, intersection, clip, dissolve, union, convex hull, difference, merge, spatial join, XY shift, reprojection, Sextante geoprocessing.
  • Graphical editing: add event layers, snapping, grid, flatness, command stack, undo/redo, copy, move, simmetry, rotate, scale, edit vertex, internal polygon, matrix, explode, split, join, autocomplete polygon, insert point, multipoint, line, arc, polyline, polygon, rectangle, square, circle, elipse.
  • Alphanumeric editing: manage fields, edit registers, field calculator.
  • Catalogue and Gazetteer services
  • Vectorial representation: unique symbol, quantities (dot density, intervals, graduated symbols, proportional symbols), categories (expressions, unique values), multiple attributes, save/load legend, symbology constructor, symbology levels, symbology libraries.
  • Raster representation: brightness, contrast, enhance, transparency by pixel, opacity, colour tables, gradients.
  • Labelling: Static labelling, advanced labelling, individual labelling.
  • Tables: statistics, filter, ascending/descending order, link, join, move selection, export, import fields, coding, normalization.
  • Layout constructor: page layout, cartographic elements (view, legend, north, scale, frames, image, text, graphic), grid, templates.
  • Printing: to PDF, to Postscript, export to several image formats.
  • Network analisys: network topology, stops manager, minimum path, connectivity, minimum spanning tree, origin – destination matrix, emergency / nearest facilities provider, service areas.
  • Raster and remote sensing: statistics, filters, histogram, scale range, enhance, save to raster file, vectorizacion, Region of Interest (ROI) definition, general components, georeferencing, geolocation, supervised classification, band algebra, image profiles, decision tree, main components, tasseled cap, image fusion, scatter diagram, mosaics.
  • Publishing: MapServer’s WCS, WMS and WFS, Geoserver’s WFS.
  • 3D and animation: 3D Views, XYZ-projected as well as spherical (planetary), 3D layers, 3D symbology, 3D editing, 3D framing, 2D and 3D animation, stereo viewing (horizontal split).
  • Topology: topological building, topological editing, generalization, reverse line direction, polygons from/to lines, lines from/to points, Delaunay triangulation, Thiessen polygons, build, clean, topological error fixing (in Batch mode).
  • Other: Coordinates Reference Systems manager, import from/export to WMC, scripting, translations manager.

Case studies in a very wide range of sectors and geographic places have used gvSIG and they are all collected in this website.
