    @dassouki: thanks for giving me the prompt to add thinks like Illustrator and image conversion. Prior to that my thinking was following the crowd trend and not looking to the wider world. :) – matt wilkie Oct 20 '10 at 19:27

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.

  • for some operations gdal/ogr is orders of magnitude faster (ref) – matt wilkie Oct 20 '10 at 15:55

Here are a few more I haven't seen mentioned yet.

Pyscripter - The best Python IDE for windows I have used, and seems to getter with each release.

Fiddler - A must for working with ArcGIS services (web debugging)

    Fiddler is one of the best tools, ever. – mwalker Oct 20 '10 at 16:03

(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 statistical procedures.

(2) Another GIS to check on the first, to supplement its capabilities, and work around the inevitable bugs. (My system typically has four or five major GIS programs available, including earlier versions of ArcGIS.)

(3) Powerful text processing tools, including the old warhorses (SED and AWK). These often make short work of data preprocessing and postprocessing tasks that otherwise would be time-consuming or impossible with the GIS itself.

(4) A computer mathematics system can be useful for specialized graphics and custom analyses. I have been using Mathematica for a few years now and find its usefulness grows in proportion to my familiarity with it. There are even some demo notebooks on its Web site showing how to do GIS entirely within Mathematica ;-). Others swear by MatLab.

(5) An array of specialized spatial analysis and visualization packages like GeoDa, GGobi, and CrimeStat.

It should go without saying that one must have the usual collection of image processing, word processing, spreadsheet, and database manipulation tools to develop appropriate graphics, reports, and tables for communicating information. Everyone has their favorites; quite a few of these are amply represented in other responses offered to the question.

(1), (2), and (3) are essential: it would be crippling not to have these capabilities. If you can't get your data into the GIS, if you can't truly analyze them once they have been processed by the GIS, and if you can't work around bugs and limitations, then you're stuck.

  • As a analyst, do you actually do serious statistic analysis and graphs? I mean, basic statistics is one thing, but people in my firm would look weird at me if I started to analyze things with statisc programs ( but I guess it depends on the type of the firm and position)? – jonatr Oct 20 '10 at 17:06

    @jonatr Interesting question. I consult. Widely. I use statistics because (a) it's obviously useful and powerful, (b) GIS users are beginning to get exposed to statistical techniques through their software, and (c) a bunch of good textbooks have appeared (mostly in England: O'Sullivan & Unwin, Bailey & Gatrell, Haining, Fotheringham, Brunsdon, & Charlton, and many more). Actually, statistics has always been lurking behind GIS techniques all along. People who are drawing conclusions merely by looking at a map are missing a chance to see more deeply by actually analyzing it. – whuber Oct 20 '10 at 18:44

Adobe Illustrator. I don't use it very much for GIS work personally but our office does for everything that goes to press (offset printing). Illustrator just has finer control over everything. True bezier curves, more line generalization and simplification options, text flow & kerning, multiple columns, great keyboard usability for switching tools and functions, object transparency, CMYK colour handling, and more.

When cartographic excellence and/or combining maps with large blocks of text and figures is the goal, Illustrator is great complement.

    I've used Inkscape a few times for map projects at home. It's okay for small and uncomplicated compositions, but quickly gets very slow and loses responsivity as the number of objects grows. I hope this changes as I quite like the program aside from that. – matt wilkie Oct 20 '10 at 17:01
  • Additionally the GIS plug-in for illustrator Mapublisher is an excellent compliment if you enjoy working in illustrator. Want to bring in some geodata into AI, keep it's attributes and spatial reference, edit it using AI's robust vector tools like the pen tool or simplify while adding Bézier curves? Then this tool is a must have. – clhenrick Oct 21 '13 at 13:31

I find Eclipse with the Pydev extension an absolute must for the scripting I do with ArcGIS. It makes life so much easier, especially now that Arcpy from ArcGIS 10 code completes.

Fore quick manipulation of text files I find Notepad++ to be the way to go, especially with all the Regex support.

For version control these days I use Git, though I have used SVN before


CAM Studio: if a picture is worth a thousand words than moving pictures should be worth a thousand words times whatever your frame rate is. It's been valuable to me for demonstrating various workflows in ArcGIS. And for documenting issues for sending to ESRI support.


Visual Studio 2010 for ArcGIS Engine and Silverlight API development.

Expression Blend for Silverlight/Silverlight API development.

Expression Encoder/Screen Capture for video transcoding and screen capture.

Notepad++ for one-off "text file" editing and scripts for Python.

Tortoise SVN for version control.

BugTracker .Net for bug tracking.

The latest version of all major browsers to ensure that the stuff I made for the web actually works as anticipated (and often it does not, but it's certainly better than it used to be).


This has been mentioned a few times as part of a collection but I want to highlight it specifically: a decent text editor. Where decent means: can easily handle 100 megabyte files and hopefully larger, syntax colouring, and regular expressions (or some other means of complicated search and replace patterns), and mutltiple undo for the essentials. Also beneficial are macros, mutliple clip boards, snippet libraries, and keyword expansion.

A text editor is the only tool I have used almost every single day I've worked on computers professionally (about two decades), and I'm not a software developer (though lately I've been exploring that a bit). Every computer and every operating system I've ever used has one. It's the only truly portable and non-expiring tool and skillset -- I've now become proficient in 2 now-dead GIS platforms (Pamap, Mapinfo), 2 more almost-dead (ArcView3, ArcInfo Workstation), and 1 will-someday-pass (ArcGIS). (Not to mention ones I've spent time to become somewhat familiar with but not proficient: Autocad 9, Quantum, Udig, Jump, ...) Each one has sucked up hundreds of not thousands of hours of learning and synapse connections which are now largely thrown away or dormant.

Text editing has been the the only constant. There has been a fair bit editor turn-over, but the skillsets have been more transferrable than other classes of programs.

  • I am aware Mapinfo is not dead to the industry, it is not used anymore in my region and those I interact with though so it might as well be - to me. Same caveat for ArcView and ArcInfo (which I still use, but not so much anymore). – matt wilkie Oct 20 '10 at 16:51
  • +1 for mentioning a tool genre I toatally forgot about, although even as an analyst (and a wannabe programmer) I use it daily – jonatr Oct 20 '10 at 17:01

Clickie: http://www.defoort.com/en/clickie/

Adds a right-click Copy Path Name and Open DOS Prompt. I use it all the time to copy paths for pasting into ArcCatalog.

    Since Win XP, you can right-click the folder holding the Shift button pressed. You will get an option Copy as Path and Open command window here. No additional installation is required for that. – Alex Tereshenkov Feb 23 '15 at 8:06
  • A coworker showed be that a month or so ago, which is great if you are bouncing around different VMs or servers. Still use Clickie on my workstation because the left hand holds my coffee. – Jay Cummins Feb 23 '15 at 11:05

SysInternals: tcpview, procmon are invaluable. I use DebugView to connect to other workstations and figure out why my code doesn't work on their workstations when it works perfectly on my dev box.

I probably do a pskill arcmap and pskill arccatalog more than I care to admit.


I use

  • TOAD for SQL Server
  • Wing IDE
  • ArcGIS Diagrammer
  • Notepad++
  • UNIX for Win32
  • MS Access
  • Gaia View (Carbon Project)
  • Visual Studio
  • RealVNC
  • VMWare Vewer
  • VMWare Infrastructure Client

Just to name a few of the apps I tend to use every day :)

Have Fun, CDB

Update - I also use Google Chrome, Fiddler Tool and Magic Disc

  • Gaia View (Carbon Project) Great for searching out WMS layers and such ... also does a heap more – Jamo Nov 5 '10 at 6:07
  • We use TOAD with our Oracle databases, it's been a great tool for querying our SDE and other schemas. (DB links are my friend.) Some of the updates can be flakey at times. – TroutSlayer Jan 25 '11 at 19:21

I typically use FME from Safe Software (www.safe.com) as a complementary Spatial ETL tool for my GIS Desktop/ Server software. The obvious reason being the robust support for 250+ CAD/GIS formats in FME and its "neutral to any format" approach to handle true data interoperability needs from simple to complex ones.


When I'm using Sql Server 2008, I really like developing spatial sql queries with Sql Server Management Studio (SSMS).

Update, forgot to mention Sql Server spatial tools.


Reflector, for decompiling .NET assemblies.

  • Decompiling is one great use. But I find it even more useful as an alternative for Object Model Diagrams. Trying to figure out how to do Query Interfaces is so much easier when Reflector will just tell you the dependencies. – jvangeld Nov 10 '10 at 3:27

This may sound a little weird, but I use a local install of MapServer on my desktop machine as a non-server tool.

  • I use the query templates to generate most of my KML files.
  • It provides a very reasonable way to visualize data based on PostGIS queries.
  • 1
    I used Mapserver as a quick layers assembly and cropping tool. Configured to output vector PDF and with a php script to automatise the extraction, i was able to churn out the required amount of maps in the little time accorded. – Laurent Jégou Jan 27 '11 at 12:47
  • SQL Server Management Studio - use this everyday to examine data and poke around in SDE
  • Notepad2 - awesome text editor
  • VisionApp for RDP remoting into servers
  • Informatica for ETL jobs - XML/text to SQL Server
  • Visual Studio 2008
  • Google Chrome
  • Tidal Enterprise Scheduler - we use this to schedule jobs. It allows you to chain jobs together and set dependencies.

I find myself relaying more and more on ms-excel and ms-access as means to cross check or repair table data.

Back when I was in the university I couldn't manage to do GIS stuff without using constantly a Capture program (such as good old Painter or yet a better one such as faststone capture).


Non-GIS image conversion programs. In addition to pdf map distribution also mentioned in this topic we distribute our maps as raw full size images and Zoomify. For this workflow we need to convert the pdf to full resolution images. The tools used here are GraphicsMagick, Ghostscript, XNView, Photoshop (and Gimp) and Zoomify Converter (though hopefully the recent addition of geospatial pdf to gdal will enable me to chop that list down to two!).


A PDF Viewer. We're standardized on Adobe Reader but also use GSView (Ghostscript), NitroPDF and others. We are a map-centric shop and PDF is the best way to get an accurate, repoducible, and distributable snapshot of a map composition that will be usable for years on a variety of machines and operating systems (more here). It is our primary means of distributing maps to the public and other agencies (our map site).

update: It's also our primary means of printing. For drafts and in-house we've found it's more reliable and faster (with multiple copies) to create a pdf and then print from that then direct from Arcmap. This also allows non-gis staff to print the hardcopy maps we distribute and sell to the public.


Toad for Oracle Sql developer Dreamweaver Sql server management studio Snagit (for all the documentation.....) flex4 And just about every browser to make sure our web apps work for everybody. Mind mapping software VMWare workstation


I don't see GPS related software mentioned.

I use Garmin Mapsource software heavily to view/check our local community GPS maps, as well as to check POIs and tracks captured using my Garmin GPS receivers (Nuvi 205W and 60CS).


For web services,

WMS Inspector firefox addon

Wireshark for inspecting data coming from webservices (work on intranet/internet, desktop application or web applications)

Using Live HTTP Headers firefox addon to see all network transactions (like wireshark but smaller, limited to browser exchange but you see headers better compare to firebug)

TCPMon for monitoring network too

About developpement,

Firebug and FirePHP

Webdevelopper toolbar firefox addon

Notepad++ (Windows), vim (linux), Eclipse PDT + Xdebug (for PHP)

Winmerge to compare directories and files (Windows) or Kompare on Linux KDE (apt-get install kompare)

Filezilla client for FTP

SVN (Tortoise or command line) or Git (command line)

Cygwin to power up Windows DOS console with lot of linux tools (access to ssh, vim, iconv, cut, sed, grep, find, history and much more like pipes)


We use PostGIS as a "Counter-Enterprise" GIS to compliment the ESRI stuff (ArcGIS/ArcSDE). When great flexibility is required and time is in short supply (daily), PostGIS always saves the day. Most often OpenJump with the DBQuery Plugin serves as the Workbench. Now ArcGIS 10 has the Query Layer functionality which can bring PostGIS flexiblility directly to the ArcGIS Desktop (the camel's nose, or should I say elephant's trunk :-), pokes a little further under the tent !!!).

  • can you specify what actions you do with PostGIS/OpenJump that you can't do (or do slower) in ArcGIS? – jonatr Nov 7 '10 at 21:58

I tend to use the following:

NotePad ++ - use this daily for editing all kinds of files.

EasyGPS - for downloading gpx files from out garmin gps units.

MS Access and Excel - useful for doing quick data analysis, comparing and cleansing.

OSM2MIF - Converts MasterMap data to MIF format.

OSGeo4W - use this to install QGIS and all the related stuff

Visual color picker 2 - very useful for finding colour codes by sampling an area of the screen

Colorbrewer - use this all the time for colour schemes.

Photoshop / GIMP - great for image work.

Adobe Acrobat - we PDF a lot of maps to include in reports. Enables users to print from PDF rather than the GIS software.


CASS software, to validate, correct, and standardize addresses, detect duplicates, detect mail drops, categorize residence vs. business, append ZIP+4, append suite numbers, confirm deliverability, convert rural boxes to street addresses, etc.

  • 1
    Please add why/how CASS software complements your GIS software. As is now it just like spam to me (linked page says "buy,buy.buy" without much info itself). – matt wilkie Nov 4 '10 at 16:51
  • It also looks like spam to me but perhaps I can help that. CASS and "address validation" can almost be used synonymously. CASS is a US Postal Service certification. A CASS-certified address means there is a verified delivery point, that a physical address is not only in the right format and has a house number in the correct range but it actually receives postal mail and is thus a real location. As part of the address validation process (CASS certification process) street and city spelling is addressed and standardized addresses can then be deduplicated. I'm a street genius, I should know. – Jeffrey May 10 '13 at 16:57

I have to recommend SchemaSpy for learning new databases and remembering old ones. It's also a great database development tool. http://schemaspy.sourceforge.net/


This has been mentioned many times already, but a good text editor. I prefer Geany and I also use it as an IDE for python, especially with ipython running in the terminal window.

I always use GPSBabel for downloading data from our consumer grade GPS units.

PicPick get used a lot for simple graphics work, screen captures, color picker, magnify, measure, etc along with GIMP.

One of my most used programs is Tomboy. It is not GIS specific at all but is a note-taking software that helps me keep track of all my projects, notes, and todo lists. It is cross platform and syncs between all the computers I do work on(and read-only on my android phone) so I always have my notes available. It is a must have for me since i work from a couple different computers at work as well as from home.


Spatial and non-spatial ETL (Exrtact, Transform, Load) tools are very valuable for data interoperability and converting data schemas and file types.

  • Safe Software FME
  • ArcGIS Data Interoperability Extension (subset of FME)
  • Spatial Data Integrator
  • GeoKettle

More discussion on this here.


Lots a great resources on this thread!

Two that i did not see listed yet:

For working with various code the find / replace (among other) features in TextPad is awesome... it is better than notepad when needing more complex data manipulations.

GPS Visualizer for generating elevation (sometimes called altitude) profiles and many nice conversion tools has been a huge help.
