Alex Leith

I am a GIS guy, a developer, I do software and I'm a practiced spatial data wrangler. I currently work at CRCSI in Hobart, Tasmania. I have a Surveying and Spatial Sciences degree and completed Honours in 2010. This is a little website about me.

What I do

While I have extensive experience with specific GIS software products, including ArcGIS, FME, MapInfo, QGIS, Eonfusion, GRASS, GDAL/OGR, GeoServer, and databases, including SQL Server, Oracle and PostGres/PostGIS. I'm pretty good at being software agnostic, or software opportunistic! I understand software and IT and how it all fits together, from the kernel to the browser, from the database to the desktop. That said, the following lists contain some more specific skills.

GIS Stuff

  • Map creation
  • Basic through advanced GIS analysis
  • Algorithm implementation
  • Software process refinement
  • Batch scripting and automation
  • High level general software skills, including wide GIS experience

Software Stuff

  • Research and development of spatial models including flood and urban growth modelling
  • Model implementation and testing
  • Deployment of mobile data collection solutions
  • Virtual Server deployment and configuration, including nightly
    scheduled tasks and scripted automation
  • Web-mapping research, development and deployment

Code Stuff

  • I write Python code to stick things together
  • I write C# for business applications and have implemented spatial algorithms for Eonfusion
  • I have familiarity with shell, batch and Powershell scripting
  • I'm learning javascript actively (and getting ok)
  • And I have studied Java in the past

What I've Done

Honours Thesis: Urban Growth Modelling

Urban Housing Growth Model

Development and implementation of a model of urban housing growth for Kingborough and later the Greater Hobart region. You can download a copy of Alex Leith's Urban Housing Growth Model thesis here.

Crash Maps for GeoNext Hack Competition 2015

Alex's Crash Map

An exploration of Victorian crash data. Check out the crash maps here.

Interactive Planning Scheme Web-Map

Glenorchy Planning Scheme

An interactive map was developed and used for four Tasmanian councils to present their draft zoning maps. You can view Glenorchy City Council's Draft Interim Planning Scheme here.

Graffiti Data Capture

Graffiti in Glenorchy

Research and deployment of a simple forms based system, Open Data Kit, to capture information about graffiti for Glenorchy City Council. This one made the news! And you can see the resulting Graffiti in Glenorchy map here.

NRM Web-Map

NRM Regions Map

This is just a little web-map, but it uses some nice stuff! There's TopoJSON used to store the vector data, which means small file sizes and retaining interactivity, and Leaflet for the mappy bits. Check it out: NRM Regions Map.

Hobart Population Graph

Hobart Population Change

An exploratory graph that shows population by dependency ratio, which is where there are a higher proportion of people in young or older age groups, by suburb for greater Hobart.


You can contact me about all kinds of things:

  • Consulting - I can do work rapidly in a number of areas, including web-mapping (simple and complex), spatial data wrangling and software development. My consultancy is called Auspatious.
  • GeoRabble and other spatial community events - I do GeoRabble in Tasmania, and you can get involved too
  • Whatever else - get in touch, tell me what's up or what's an opportunity.
