GIS DATA VIEWERS AND NEVADA DATA

Free or inexpensive GIS data viewers that can be used to view and query the various GIS data sets that are available on the Nevada Bureau of Mines and Geology (NBMG) Web site. Listed below, with links to download sites, are three free GIS applications that can be used to view and query these data sets. At the bottom of this document is a list of some Statewide Nevada GIS data sets with Web links to zip files that contain the GIS data. These data sets are available free of charge.


===== MAPWINDOW GIS =====

Homepage: http://www.mapwindow.org

MapWindow GIS desktop application is a free, open source, standards-based standalone software package that you can use to view and edit GIS data in many file formats.

The software includes plug-ins for various geoprocessing tasks (e.g. buffer, merge, etc.), watershed delineation, accessing online data sources, and an experimental geodatabase plug-in. The attribute table editor can be used to write simple queries, and there is a complete scripting editor that allows you to write and run scripts in VB.NET and C# directly in the MapWindow program.

Download MapWindow GIS if you need a simple map viewer, or if you want to write your own custom plug-ins to distribute to other users.

MapWindow is an extensible geographic information system. This means that you can write plug-ins to add additional functionality (models, special viewers, hot-link handlers, data editors, etc.) and pass these along to any number of your clients and end users. MapWindow includes standard GIS data visualization features as well as DBF attribute table editing, shapefile editing, and grid importing and conversion. MapWinGIS ActiveX includes a GIS API for shapefile and grid data with many built in GIS functions.


===== ARCEXPLORER - GIS DATA VIEWER =====

Download site: http://www.esri.com/software/arcexplorer/index1.html

ArcExplorer is a lightweight GIS data viewer developed by ESRI. This freely available software offers an easy way to perform a variety of basic GIS functions, including display, query, and data retrieval applications. It can be used on its own with local data sets or as a client to Internet data and map servers.

With ArcExplorer you can:
- Display and query a variety of standard data sources including: ESRI shapefiles. ArcInfo coverages, Images, ArcIMS Services (i.e., Geography Network sources).
- Pan and zoom through multiple map layers and identify, locate, and query geographic and attribute data.
- Symbolize your data based on attributes contained in your data layers to create thematic maps.
- Perform basic spatial analysis tasks on the geographic data, such as selecting and buffering features.


===== QUANTUM GIS =====

Homepage: http://qgis.org

Quantum GIS (QGIS) is a user friendly Open Source Geographic Information System (GIS) that runs on Linux, Unix, Mac OSX, and Windows. QGIS supports vector, raster, and database formats. QGIS is licensed under the GNU Public License. The current official release is 1.0.2, aka "Kore".

Supported data formats include:
- spatially-enabled PostgreSQL tables using PostGIS and SpatiaLite.
- most vector formats supported by the OGR library, including ESRI shapefiles, MapInfo, SDTS and GML.
- raster formats supported by the GDAL library include digital elevation models, aerial photography or landsat imagery.
- GRASS GIS mapsets.
- online spatial data served as OGC-compliant WMS or WFS.

QGIS allows you to create, edit, model, and export spatial data using a variety of analysis and editing tools.
