QGIS. Although I do most of my analysis using ESRI based tools, QGIS is extremely fast for quickly examining a shapefile, and zooming/panning/reading the attributes. I don't mean this in a derogatory way, as QGIS is also a wonderful open-source desktop GIS; but for quick file opening/closing it's wonderful and the quickest I've found.

Fiddler is excellent. Update Suppose I'm looking at a Web App, like Esri's Redistricting Online ... ... and I become curious about the mapservices it uses. I can fire up Fiddler and see what Urls it is accessing. I can right click and copy the url and paste into a web browser, since we're dealing with REST ... ...

There are quite a few alternatives and I've actually written a short book on the subject entitled "Online GIS - Meet the Cloud Publication Platforms that Will Revolutionize our Industry" but that's a little outdated now. Here's an updated summary: MangoMap: Very easy to use, no coding required. Lots of tools and functionality available to make really ...

GIMP and INKSCAPE I use these two for cartographic purposes. Gimp has good raster support (until they get huge/GB in size, then you run it on a linux OS!) and Inkscape handles vectors really well.

Benjamin already mentioned SAGA GIS, but just the name so I would like to add more info about this excellent SW: SAGA (System for Automated Geoscientific Analyses) SAGA is also free and opensource like QGIS, but it is focused on raster data analysis and processing. The standard modules are: File access: interfaces to various table, vector, image and ...

MapDroyd is excellent if you want to store some OpenStreetMap for offline use. GPSLogger for Android is a lightweight GPS logger with lots of useful tweaks [control over time/distance of logs, OSM integration, auto email of tracks, and easy on your battery]. EpiCollect developed at Imperial College London together with web based management ...

Begin by considering the type of dam construction. Some dams are high, thin, and curved; others--including earth dams, which are perhaps commonest--tend to be straight across and quite thick, with slopes that vary from 1:2.5 to 1:5 (40% to 20%). For many examples, see the illustrations in B. Bassell's 1904 study on earthen dams. You need to create a DEM ...

For statistical analysis, there is R. An integration of R with ArcGIS provides the Geospatial Modelling Environment. Using the right libraries you can easily handle shapefiles and raster data in R RStudio is a powerful IDE with debugging and improved data handling for R.

Color Oracle - a colorblindness simulator for Window, Mac and Linux. I use this for checking the "look" of my composed maps.

GDAL/OGR When data doesn't look right or work in my desktop GIS, a simple ogrinfo usually provides the answer. gdal_translate and gdalwarp for quick raster operations, and of course the gdal Python modules. Completely unrelated and more of a Web app, but ColorBrewer is great for figuring out color values for different data classes.

The OSGeo is a repository for the open source GIS community. There are a few applications highlighted here that may suite your needs. Quantum GIS (QGIS) - QGIS can handle a variety of vector and raster GIS data sets. The application interface is intuitive, and has a similar look and feel like ESRI ArcMap. The application may also be installed on a ...

Here's a vote for Quantum GIS with GRASS plugin enabled as your desktop application. (QGIS is available on Windows, MacOS X and Linux). OGR/GDAL will take care of nearly any file format. Store all your data on PostgreSQL/ PostGIS and serve it out with Geoserver. Link to QGIS API Documentation.

IDL is a fantastic stand-alone programming language (you do not need ENVI). I particularity like it for very fast matrix processing on large arrays. @Aaron makes IDL sound much less flexible then it really is. The majority of IDL development came out of the Physics and Astronomy communities. There is robust support for mathematical and statistical ...

Eclipse and PyDev for Python coding - the latest version (finally) allows you to run a script without it being in the project, and has some other great features as well (break on exception etc.). That and the almost unlimited other number of extensions that you can install in Eclipse. Git for version control. Free, easy, and you don't need to install any ...

You can do it in QGIS using symbol transparency, feature blending mode and symbol color. Notice the difference between Layer Transparency and blending mode(that will be applied to all features) and the symbol transparency and feature blending mode that will stack with other features in the same layer. All seetings are available in Layers Properties > ...

The full version of ArcGIS (ArcInfo) with all the extensions is far beyond anything that Manifold can offer, but it is also more than ten times as expensive - so that is a fair comment. The base-price listed above even seems low for the full version so I suspect it is for an ArcView or maybe ArcEditor licence rather than ArcInfo. QGIS does have digital ...

I wonder why MAPNIK has not been mentioned yet. It is also pluged in to QGIS. Very nice tool for easily making astonishing looking maps.

From a remote sensing perspective, the main benefit of IDL is that it extends the capability of ENVI similar to how the Python arcpy site-package extends the functionality of ArcGIS. If you will not have access to the ENVI platform, consider learning a different programming language. Additionally IDL is a commercial product whereas Python is open-source and ...

(1) An industrial-strength statistics package, like Stata or R. The question refers to "analysts" and I take that job to include deriving meaning from the data, helping people make appropriate conclusions, and identifying optimal actions. That more or less describes statistical analysis, but no GIS is suited for anything but the most limited of ...
