# General References {#general-data-hacking-and-programming-references}
## The basics of being a data scientist

*   Have a hypothesis - even if you're making a tool/api that helps people with their questions too, remember what the objective of that is.
*   Find the people and tools you need to prove/show/find. This rest of this page will help with the latter.
*   Analyse and present results -  were they what you expected? Do they help explain to others what you have found out? Can present as a interactive data visualisation or a web/mobile application or just a infographic/motion graphics video that tells a story.
Please note, there are a combination of Analysis and Visualisation tools in each of the major categories below.

**Statistics**

[http://greenteapress.com/thinkstats/html/index.html](http://greenteapress.com/thinkstats/html/index.html)

**Programming**

Programming is valuable skill for manipulating and displaying data.

Basic tutorials for a variety of languages are available for free online or you can learn

interactively with websites like [http://www.codecademy.com/](http://www.codecademy.com/#!/exercises/0). for JavaScript or [http://www.learnpython.org/ ](http://www.learnpython.org/)or [http://tryruby.org](http://tryruby.org/)

[https://developer.mozilla.org/en/JavaScript](https://developer.mozilla.org/en/JavaScript) - especially for web applications and visualisations, you'll need a basic understanding of JS. Common libraries like prototype or jQuery can help

**Accessibility/User Experience**

WCAG guidelines not only make a web app accessible but make it a better experience for all users! Even if not making an app, good to consider these things to do and not do: [http://www.w3.org/TR/WCAG/](http://www.w3.org/TR/WCAG/)

# API Development {#api-development}


So an API isn't just an XML file ![;)](http://www.govhack.org/wp-includes/images/smilies/icon_wink.gif) 

A good web based data API:

*   Is logically organised
*   Can filter returned data
*   Can return results in different open formats (CSV/JSON etc.)
*   Is efficient and responsive by using caching and databases appropriately
*   Handles errors gracefully
*   Monitors and controls access (to show benefit realised of API and prevent abuse)
*   Provides appropriate documentation with examples

Some people like sensis [http://](http://developers.sensis.com.au/)[developers.sensis.com.<wbr>au</wbr>](http://developers.sensis.com.au/)[/](http://developers.sensis.com.au/) use a provider like[http://](http://mashery.com/)[mashery.com](http://mashery.com/)[/](http://mashery.com/) or [https](https://apigee.com/)[://](https://apigee.com/)[apigee.com](https://apigee.com/) or [http://](http://apiaxle.com/)[apiaxle.com](http://apiaxle.com/)[/](http://apiaxle.com/) or [http://www.3scale.net/](http://www.3scale.net/) which handles making a good API for them.

Atlassian have a great page on what makes a good API [https](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)[://](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)[developer.atlassian.<wbr>com</wbr>](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)[/display/REST/](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)[Atlassian](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)[+<wbr>REST+API+Design+Guidelines+<wbr>version+1</wbr></wbr>](https://developer.atlassian.com/display/REST/Atlassian+REST+API+Design+Guidelines+version+1)

# Infographics and Data Visualisation {#data-visualisation}

Infographics try to contextualise charts and graphs to tell a story. Data vis builds on this to find new ways to design insight.

Most of the categories to follow have visualisation tools specific to their purpose.

You can find some data visualisation tools below:

[http://www.visualisingdata.com/index.php/2011/07/part-6-the-essential-collection-of-visualisation-resources/](http://www.visualisingdata.com/index.php/2011/07/part-6-the-essential-collection-of-visualisation-resources/)

## Wrangling

### Converting
There are many spatial data formats and often the one your tool requires is not the one the dataset is provided in
Online
  - http://converter.mygeodata.eu/vector kml exporter for shp
or locally using GDAL

### geocoding
cloudmade, google (but you must display on a Google Map).

Easiest way to do is with a Google Spreadsheet/Fusion Table http://williamparry.blogspot.com.au/2011/04/putting-data-into-google-fusion-tables.htm


## Analysis


### PostGIS

[![](http://www.govhack.org/wp-content/uploads/postgisexample-300x130.jpg "postgisexample")](http://www.govhack.org/wp-content/uploads/postgisexample.jpg)PostGIS is an extension for the PostgreSQL database server that allows you to store and manipulate geospatial data on a large scale. For example finding which points are in an area or what points are closest . It is also very useful for storing geospatial data because it can convert between all major formats including ESRI Shape files and Google Earth/Maps KML.

### Quantum GIS

[![](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_m50afbe88-300x160.jpg "QGIS Screenshot")](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_m50afbe88.jpg)QGIS is a graphical desktop application that allows viewing and editing of geospatial data. Some good base maps are available by adding the WMS layer/server [http://irs.gis-lab.info/](http://irs.gis-lab.info/)

## Visualisation

### Layar and other augmented reality tools

### Google Fusion Tables/ChartsBin/[OpenHeatMap](http://www.openheatmap.com/)

[![](http://www.govhack.org/wp-content/uploads/fusiontablesscreenshot-300x168.jpg "fusiontablesscreenshot")](http://www.govhack.org/wp-content/uploads/fusiontablesscreenshot.jpg)Input a numerical values and areas to a spreadsheet and maps are produced

### [Cartographer.js](http://cartographer.visualmotive.com/)

[![](http://www.govhack.org/wp-content/uploads/cartographerjs-300x187.png "cartographerjs screenshot")](http://www.govhack.org/wp-content/uploads/cartographerjs.png)Input data as JSON and maps are produced.
See also d3 maps.
  - http://bost.ocks.org/mike/map/


### OpenLayers/Google Maps/[Leaflet](http://leaflet.cloudmade.com/)

[![](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_512fcbe1-300x173.jpg "OpenLayers Screenshot")](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_512fcbe1.jpg)Display points and different layers. Leaflet is the easiest to use if you just want to show points with popups when clicked on.
There are wrappers for Google maps like http://hpneo.github.com/gmaps/examples.html and Mapstraction that can make it easier to use too.

### NASA World Wind/Google Earth

[![](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_4dda24a4-300x261.jpg "WorldWind screenshot")](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_4dda24a4.jpg)Google Earth provides 3\. viewing of KML/GML files which represent points and shapes, both through a desktop application and a web plugin. These can be extended with interactive features that allow you to view by timeline or have animated tours between different points. You can also develop and customise your own viewer with the open source [NASA World Wind toolkit.](http://goworldwind.org/demos/)

# Tabular Data Tools {#tabular-data-tools}

## Wrangling

Tabular data may have duplicate entries or incorrect formats (varying ways to enter dates/phonenumbers etc.). There are tools to quickly fix common problems

[DataWrangler](http://vis.stanford.edu/wrangler/)/[Google Refine](http://code.google.com/p/google-refine/)

[![](http://www.govhack.org/wp-content/uploads/google_refine_interface.png "google_refine_interface")](http://www.govhack.org/wp-content/uploads/google_refine_interface.png)Clean up duplicate or inconsistent data entries.

Can also use general purpose tools; grep/awk/sed
regex http://www.regexper.com/ http://www.debuggex.com/?re=&str=

## Analysis

### Excel / Calc

Great basic analysis and viewing. Older versions can be limited to 6500\. or so rows. Eg [http://www.tcij.org/training-material/car/data-mining/3474](http://www.tcij.org/training-material/car/data-mining/3474)

### PostgreSQL/MySQL

[![](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_209ee972.jpg "SQL screenshot")](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_209ee972.jpg)Next step up, large datasets can be manipulated/extracted efficiently for example [http://www.postgresql.org/docs/8.4/static/tutorial-window.html](http://www.postgresql.org/docs/8.4/static/tutorial-window.html) , no built-in data visualisation though.

### [Miso Dataset](http://misoproject.com/dataset/)

[![](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_m53b7ee38-293x300.png "miso screenshot")](http://www.govhack.org/wp-content/uploads/How-to-participate-in-GovHack_html_m53b7ee38.png)Javascript data transformation library - especially good if you want to use the output for javascript interactive visualisations because the transformations can be done on-the-fly by users.

### R Statistical Language

[![](http://www.govhack.org/wp-content/uploads/rstudio-windows-300x249.png "rstudio-windows")](http://www.govhack.org/wp-content/uploads/rstudio-windows.png)Advanced data analysis, can find and visualise trends in large datasets. Some reference resources to learn the language [http://cran.r-project.org/doc/manuals/R-intro.html ](http://cran.r-project.org/doc/manuals/R-intro.html)There are also some addons that provide graphical interfaces that make it easier to use such as Rattle [http://rattle.togaware.com/](http://rattle.togaware.com/) , RStudio [http://rstudio.org/](http://rstudio.org/) or Deducer [http://www.deducer.org/pmwiki/pmwiki.php?n=Main.DeducerManual](http://www.deducer.org/pmwiki/pmwiki.php?n=Main.DeducerManual)
