We’ve been working with one of clients on marker performance. The problem with markers is they take a long time to load up especially when you add a lot of makers eg. over 100 markers. The performance gets worse when you add polygons or polylines to the map and as you add or remove layers to the map

One of the problems is that the marker class is full of features – Info Windows, shadows, custom icons etc. The browser has to manage all of the DOM objects for the functionality.

To improve the performance, we’ve created a new marker class called GMarkerSimple. The class has a cutdown set of features ie. ‘onclick’ and ‘openInfoWindow’ to improve the speed. We have also introduced a marker cache to ‘cache’ marker objects in memory to improve performance when adding and remove marker layers.

The performance improvement is quite astounding, especially when you compare it to Google.

FireFox 2.0.14

IE 6.5

Don’t take our word for it. Try it for yourself – 100 marker test, 300 marker test and the browser killing 1000 marker test !

I was found this picture on my hard drive showing where all the government agencies are in NZ. We created the image for the Broadband strategy challenge.

I thought it was kinda cool.

Its a big image, a 1.7Mb jpg.

I attended the Spatial barcamp and GoVis conference last week and here are my thoughts.

I thought the conference was great way for the industry to get together and network. It was nice to see some interesting talks from the speakers on how GIS was integrated into enterprise solutions

Open source good, Open standards better

The New Zealand Geospatial Office is promoting the use of open source tools (mapserver, mapguide etc) and open standards around government agencies. Its great to see more open source being promoted.

The use of open standards, KML, WFS, WMS etc will be a good way for people to share data. As a industry we already have a lot of proprietary formats, we need to promote open standards to enable better interaction between organisations.

I would offer a word of caution, using open source tools (just like anything else) is not going to be a magic bullet solution. You need to select the right tool for the job.

At ProjectX, we used a number of open source and propriety tools to make our maps. We’ve switched from mapserver to Manifold and now back to mapserver because the quality of the generated imagery wasn’t good enough for us.

Innovation under the surface

It was great to some innovations and ideas that going on out there. Big things like Aerial capture via microlight and dynamic object tracking systems, and smaller things like Napier City council making more of it core data available via open source tools.

It made me think, that as an industry (and companies in NZ) we don’t market our ideas very well. Even at ProjectX, we have a lot of things we built for clients or internally that is innovative and leading edge that never sees the light of day.

To that end, I’m working with Gavin from gis.org.nz to create a news portal for GIS / Geo-spatial news in New Zealand. We’re looking at creating a news system for companies to talk about new products, ideas and issues in the our space. We’re in the process of setting it up properly now, so stay tuned.

Partnerships

It was refreshing to see that all the GIS departments in the Auckland region were working together. Personally I don’t think there are enough partnerships between players. There is a lot of innovation happening in NZ, and we need to work together to take on the world!

I’ve been asked to be the panel for  the latest UP event – a tale of four  cities at SYN bar tomorrow night.

A recent article in Time said that New York, London and Hong Kong were three hub cities of the world. These cities foster innovation, creativity, and set global trends, and generally what happens there affects the rest of the world. Unlimited Potential think the Wellington should be added to the list as the new innovative ‘southern hemisphere hub’, and on May 6th we’ll tell you why.

I’m a big believer in Wellington and a big supporter of Silicon Welly and Summer of Code which are doing their bit at making Wellington an international technology destination

And there’s lots of pizza and beer  – Make sure you RSVP on the website.

We’ve been working hard over the past fews months fixing bugs and making improvements to ZoomIn.

Here’s a summary of what we’ve been working on:

New Functionality

• Activity Feed – Here you can see the last 20 actions by our members on ZoomIn.
• Popular places – This is where you can see the 10 most popular places, today, this week and of all time.
• GeoRSS – We’ve added GeoRSS feeds for the latest places, photos and comments . (For an example of what the GeoRSS feed looks like, have a look at this example on Google.)
• Nearby places – On the information page, you can find out what’s nearby your favourite places eg. Here’s whats nearby popular 3c bar.

Usability Improvements

We been make lots of improvements to the functionality on ZoomIn.

• We improved our default URL system so that now you can directly link to a map of an address or place or link to information about that address or place. eg. Map of Arrowtown and Information on Arrowtown.
• Search – We’ve made improvements to the search, so that it’s more accurate.
• Design – From your feedback, we’ve redesigned the map results page to fix a number of layout bugs and remove whitespace thus maximising the map. We’ve also added a new navigation slider to the map.
• Photos – We added bigger thumbnails on the information pages and user profile pages. We’ve also allowed users to change the default picture for a place.
• Enabled custom IFrame sizes for users who are embed maps on their web page or blogs.

And a whole raft of bug fixes. We’ve got a more new functionality and improvements in the wings that will be released soon.

From today on, ZoomIn allows users to choose a default photo for their places. If you are the owner of a place , you have the power to let other users choose a default photo for your place.
