What's under the bucket?!

Wednesday, January 9th, 2008

Spotted in upper Willis St today: a car with some interesting apparatus on top, and until moments before this photo was take, a very familiar logo on the side.

Google streetview car?

Looks like we may be seeing a new view of Wellington streets on the web some time soon, and we’ve heard that similar vehicles are cruising the streets of Christchurch as well.

The National Broadband Map

Wednesday, November 28th, 2007

Today’s Digital Future Summit 2.0 saw the launch of The National Broadband Map, built with ProjectX technology. Its purpose is to help improve access to broadband, especially in the regions, through “demand aggregation”: pooling the demand for telecommunications services in a specific geographic location.

Individual users might find it hard to convince a telco to roll out services in their area, but when those users combine, they can often reach the critical mass required to attract investment in the provision of new services. For instance, if you’re a graphic design business in a small provincial town, you might struggle to convince a provider to extend their infrastructure to reach you; but if there is also a school, medical centre and library down your street, plus several other businesses and private residents who are also interested, then the telcos might sit up and take notice.

To this end, the map shows existing state sector locations, as well as allowing businesses and private residences to enter their own locations and describe their level of demand. It also shows existing network infrastructure, and includes all the address search, autocomplete, zooming and panning functionality that is familiar to ZoomIn users.

The system was developed by ProjectX together with the State Services Commission, and involved the collation, geocoding and checking of thousands of state sector locations, and the conversion of network data from all sorts of formats and projections, as well as building on existing ZoomIn Mapping System API functionality. For instance, the ZMS has always had the ability to display vector layers (polylines and polygons) as overlays on the maps, but the size and complexity of the network infrastructures required some hard work from our developers to optimise the performance of these layers, as well as dealing with the inevitable curly cross-browser compatibility issues.

In keeping with the Web 2.0 theme, the Map is labelled “Beta”, and it will evolve over time. Partly that will be due to the growing information base, from user-added places and as we receive more state sector locations and existing network data. There will also be functionality and usability improvements over time, and we encourage user feedback so that we can make this as comprehensive and easy-to-use as possible.

When autocomplete goes bad

Monday, November 5th, 2007

In common with a lot of AJAX-based sites, ZoomIn makes a lot of use of autocompletion, specifically to make it easier and more reliable to enter addresses. But thanks to this article from Gizmodo, we can see some of the hilarious questions that come up when autocomplete kicks in too early: Ask.com helpfully starts completing a phrase such as “is it legal to” with some bizarre and sometimes hilarious queries from other users.

But my favourite is an example that shows the touching faith that some people have in the Internet. Apparently it will answer questions that have stumped philosophers since the dawn of humanity:

Open GIS

Friday, October 19th, 2007

Following up from yesterday’s post about the Open Source Awards, here’s a new local discussion group about the use of open source software in Geographic Information Systems (GIS). As a web mapping company, we make heavy use of open source software in both the web and the mapping sides of our business: I’ll come back to the web side, but here are some quick notes on the open source GIS packages that we use.

  • PostGIS: I won’t make great claims for its performance, but the spatial extensions to PostgreSQL are pretty impressive and getting more powerful all the time.
  • MapServer: this hasn’t been our first choice for map tile rendering in most cases, but now that version 5.0 is out with its gorgeous anti-aliasing (thanks to the AGG library) it’s looking more and more appealing.
  • QuantumGIS: it’s not exactly ESRI or MapInfo, but it’s quite useful as a basic desktop GIS app, and the ability to export to SVG (for further tweaking and polishing in Inkscape, or for XML hacking) is great for publication work.
  • OGR utilities: indispensable! Good old-fashioned simple command-line tools for exploring, converting and generally mucking around with the obscure world of GIS data formats.

Awarding

Thursday, October 18th, 2007

This came as a very pleasant surprise: In last night’s NZ Open Source Awards, ProjectX won the “Open Source Use in Business” category, and NZ Summer of Code took out the “Open Source Use in Education” award.

Open Source Awards for ProjectX and Summer of Code

We’ll write some more soon about the advantages we’ve found to using open source, and some specific software that we can’t do without; but for the moment we’re all just rather stunned!
