Free data viewers for a variety of GIS data formats. These viewers allow you to display geographic data as well as perform some basic GIS functions. ArcExplorer The free GIS application offered by ESRI products. A lighter version of ArcView this application allows basic mapping and spatial querying. ArcReader ArcReader is a free, easy-to-use mapping application that allows users to view, explore, and print maps. Christine GIS Christine GIS system is free GIS software allows you viewing and spatial querying vector and raster data, creating and editing tabular data, connect DBMS by ODBC, creating applications by integrated script language. Geomatica Freeviewer Geomatica Freeview is a standalone dataviewer that allows browsing of a variety of vector and raster based data including satellite imagery. You can also access attribute data within this viewer. Geospatial Explorer Free download of this data viewer by Cyze & Associates. This viewer was especially created for environmental scientists, geologists and engineers. Natural Resources Database The Natural Resources Database (NRDB) is a GIS-based tool for developing and distributing environmental databases. Data may be output as resource maps, graphs and reports using simple selections or powerful queries. The program supports the import and export of data to and from shapefiles and supports universal (UTM) and other transverse mercator projections. Data may also be imported from Excel files, Access databases and text files. TatukGIS Viewer Natively supports wide range of vector, image, grid data formats and WMS, WFS, and WMTS services opened from the web. Comprehensive visual layer property and legend controls for deep customization of map appearance, including colors, labels, fills, line styles, symbology, thematic presentation, pie charts, sublayers and layer hierarchies… Advanced coordinate system support with nearly 5,000 predefined coordinate systems and on-the-fly reprojection. Attribute data grid table with advanced query and selection tools. TNTAtlas TNTatlas is a free Geodata viewing tool for Mac OS X and Windows. Geodata files currently supported include shapefiles, DWG, DGN, DXF, JPEG, JP2, TIFF, GeoTIFF, PNG, ECW, and MrSID formats. TNTatlas also has features for querying, measurement, printing, sketching of the displayed geodata. City Maps: A coloring book for adults is a 94-page book containing 44 maps covering cities from around the world by Gretchen Peterson Sangeeta Deogawanka discusses what it takes to develop a career in Geointelligence whether it be in security, intelligence, policy analysis, first response, technology, software development or consulting. The American Association for the Advancement of Science (AAAS) has produced a manual entitled “Introduction to Remote Sensing of Cross Border Conflicts: A Guide for Analysts” as part of a project by its Geospatial Technology Project staff to understand the use of satellite imagery as a tool for “understanding border conflicts and possible conflict prevention.” Isodistance measures routes of equal time and isochrone measures routes of equal travel times although both are typically represented as bands of polygons. Got MS Excel? Need a simple map? A little known tool in older versions of Microsoft’s Excel is the ability to create simple maps from tabular data. You can create simple chloropeth, chart and dot density maps using data organized by country, state or region. An open source application by definition is software that you can freely access and modify the source code for. Open source projects typically are worked on by a community of volunteer programmers. Open source GIS programs are based on different base programming languages. Three main groups of open source GIS […] GIS is a technological field that incorporates geographical features with tabular data in order to map, analyze, and assess real-world problems. The key word to this technology is Geography – this means that some portion of the data is spatial. In other words, data that is in some way referenced to locations on the earth Source.
