Features GvSIG Desktop

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

• Access to vector formats: SHP, DXF, GML, DWG, DGN, KML.
• Access to raster formats: BMP, GIF, TIFF, JPEG, JP2, PNG, VRT, DAT of ENVI, ERDAS (LAN, GIS, IMG), PCI Geomatics (PIX, AUX), ADF of ESRI, ILWIS (MPR, MPL), MAP of PC Raster, ASC, PGM, PPM, RST of IDRISI, RMF, NOS, KAP, HDR, RAW.
• Access to remote services: OGC (WMS, WFS, WCS, WFS-T, WPS), ArcIMS, Ecwp.
• Access to databases and tables: PostGIS, MySQL, ArcSDE, Oracle, JDBC, CSV.
• Display:zooms, panning, frames, locator.
• Query: information, area and distance measurement, hyperlink.
• 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, symmetry, rotate, scale, edit vertex, internal polygon, matrix, explode, split, join, autocomplete polygon, insert point, multipoint, line, arc, polyline, polygon, rectangle, square, circle, ellipse.
• Alphanumeric editing: manage fields, edit registers, field calculator.
• Catalogue and gazetteer services
• Vector 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.
• Labeling: Static labeling, advanced labeling, individual labeling.
• 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 analysis: 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, vectorization, 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.

• Other: Coordinates Reference Systems manager, import from/export to WMC, scripting, translations manager.

Sextante GIS has been ported to a plugin for gvSIG adding a host of raster and vector analysis functions in addition to gvSIG's impressive built-in vector analysis tools. Within Sextante, GRASS GIS can be used as extension to make its algorithms available to gvSIG users.
