2011 in review

We migrated our website to WordPress in about August 2011.

Here’s  a 2011 annual report for our blog, prepared by the WordPress.com stats helper monkeys.

Here’s an excerpt:

A San Francisco cable car holds 60 people. This blog was viewed about 1,800 times in 2011. If it were a cable car, it would take about 30 trips to carry that many people.

Proposed Presentation for Upcoming Newtech Conference

We’ve submitted a proposal to present at the next Newtech Conference, scheduled for next March in Bendigo. Here’s our abstract.

“There’s a Map For That”

Mitchell Shire Council carried out their recent annual fire inspections on an iPhone.

Without any device configuration or speciality hardware, field staff identified and recorded at-risk properties in their phone’s web browser at a rate of up to one per minute, including driving time. Property addresses were validated at the point of capture, every inspection was recorded directly to the council’s GIS server, and office staff generated daily lists of properties in seconds.

Find out what’s special about Mitchell Shire’s GIS infrastructure, and how this data capture application was developed in a matter of days using open source tools.

Newtech

Newtech Conferences are held in various locations around regional Victoria, and draw many people from local government and other organisations. We’ve participated in nearly every Newtech over the past ten years, especially in the last five years as a sponsor and presenter.

Melbourne Open GIS September 2011

Groundtruth is proud to again co-host Melbourne Open GIS on Thursday 29 September.

Melbourne Open GIS is a forum to discuss open technology, standards and interoperability in GIS. Our meetings bring together professionals from geospatial and other disciplines in a casual environment for some presentations, informal discussions, socialising and some drinks supplied by our meeting sponsors.

Presentations will include:

  • Roald de Wit (Bureau of Meteorology) – Free and Open Source Software for Geospatial Conference (FOSS4G2011) Denver debrief

MobileMapper Field Software On Magellan MobileMapper 6 GPS

Our client needs to identify properties that have long grass or other fire hazards, so property owners can be sent a letter notifying them to cut their grassMobileMapper 6 before the fire season approaches. We needed a GPS with the ability to capture points, and maybe allow the operator to pick from a list of fire hazards. Easy right?

The Magellan MobileMapper 6 GPS seemed like a good fit, and it came with its own data capture software, called MobileMapper Field. The software sounded functional enough, and it was even capable of post-processing.

So here’s what we discovered:

  • it cannot preview, test or otherwise interact with map without GPS signal (ie, can’t use in office)
  • rendering of map often took over 30 seconds, without any indication that anything was happening
  • the map didn’t seem to follow current GPS location (user may have to manually zoom out, find position, pan map, then zoom in)
  • it didn’t display labels for point objects (we needed to display house numbers for address points)
  • polygon labels often didn’t sit within polygon, causing confusing label arrangement
  • screen frequently locked up, requiring device restart
  • points could only be created at the user’s current position (ie, can’t place a point within a property)
  • cannot cancel out of creating a point, only go back and delete it after you’ve completed creating it
  • deleting a point took over 20 seconds, and didn’t indicate that anything was happening

I’m embarassed to admit how much time we wasted in trying to get a satisfactory setup of this software.

Fortunately I discovered that the client had a copy of ArcPad lying around from when they used a previous GPS. I promptly installed it on the MobileMapper GPS, and spent a relatively short amount of time (only one and half hours) trying to get that to work. It seems that the MobileMapper Field software had one last trick up its sleeve, and that was to not allow any other software connect to the device’s GPS. Resetting the device fixed that issue, and now, I’m ready to configure it for the fire inspection season, with only one week to spare before the first inspections.
