In a recent app (form) I wanted to be able to quickly see the last time I had visited a site. This form had the usual Parent/Child setup with a repeatable section that noted information every time I visited the site. Having the ‘last visited date’ on the parent side of the form meant that when I mapped the data in QGIS I could quickly create a categorised thematic by this date to see which sites might need a visit.

Here is the setup

  • App with a repeatable section called ‘observations’
  • Date field on the repeatable section for observation date  – observation_date
  • Calculated field on the ‘Parent’ (non repeatable) side of the app with the following expression

var dates = REPEATABLEVALUES($observations,’observation_date’);
var maxDate;

if (dates && dates.length > 0) {
maxDate = dates[0];

dates.forEach(function(currentDate) {
if (currentDate > maxDate) {
maxDate = currentDate;
}
});

maxDate;
}

Fulcrumapp – Support and helpdesk

I have been using Fulcrumapp for some time now helping out various not-for-profit organisations and unfortunately they have turned off their old public forum which I used to find quite useful for seeing how other users solved problems.

They now have a online one on one system so you cant see what everyone has been working on. All that past knowledge and learning, which I found quite useful, is no longer available.

They do have sites with code examples (Help, Expressions, data events) but for folks with no coding experience they get a bit geeky fairly quickly.

I have decided that when I have some success with an issue I will post it online here for all to see – hopefully someone will find it useful. In most cases these now come from the one on on one interactions I have with Fulcrum staff but I will try and make the notes as user friendly for non techie folks.

Getting in to Mapillary

OK, everyone knows I am geek but recently I noted that there was an alternative to Google street map and its available for anyone to load up their own images! I support this type of open data setup so I grabbed an action camera (contour 2+) I had in the bottom drawer and made a start on getting some local area data. The other benefit is that the imagery is available to Open Street Map users which can be especially beneficial for street names, business listings etc.

Here is one example of my imagery – a descent of kunanyi/Mt Wellington in Hobart

World Heritage Area Track Management Strategy 1994

A few folks have asked me to place this document on the web so it doesn’t get lost completely.

Its the original walking track strategy for Tasmania and in its time it was a fairly controversial document that looked at all aspects of long term track management. It covers everything from the inventory of tracks, education of walkers, monitoring, research, publications and promotion as well as regulation of walkers. Way ahead of its time!

World Heritage Area Track Management Strategy Volume 2 1994

World Heritage Area Track Management Strategy Volume 3 1994

More recently there has been an updated Walking Track Strategy for 2011 – 2020 – you can download it here

 

 

Open Data – Tasmania

The last few months have seen some changes in the availability of data for those of us that like mapping and other geeky things.

In December, the Tasmanian government started releasing some spatial data via an “Open Data Portal” where its possible to download GIS vector data such as the road network, rivers, streams, lakes, contours and even property parcels. All this data can be used with the QGIS software we are using. Just about every state is now starting to make data available which is great for volunteer organisations working with lean budgets. The data is being released with Creative Commons licencing so be sure to attribute your maps appropriately.

There has also been a change to the supply of TASMAP digital raster maps. These can now be downloaded (but not for free!) from the TASMAP eshop. Each 1:25,000 map can be purchased in a couple of formats that suits both QGIS and Garmin GPS’s. If you have a recent Garmin GPS, such as a 62 model or Etrex then each map can be loaded as a background image. There are some limitations but these can be very handy in some instances and at just $2 a map sheet its not a huge investment.

Of course if you only need an overview map then you can download the whole of Australia as a raster map from Geoscience Australia but be warned, its a huge 3Gb download and that definitely wont fit on your Garmin in its current format.

Sue and the family history

geneabloggersOn our previous website, I had a lot of information about our family history. I have recently completed an online, free university course and as part of that began a new blog all about our family history. Here is the link to  my blog: Oér the seas we go

Included in that blog is most of the pages from our previous website plus some new ones that I have been researching lately.

The blog also includes information about the courses I have been doing which now includes WW1: 100 stories which I have found to be fascinating. Check out the posts on my blog by choosing the category WW1: 100 stories.

Back Online

Like so many other sites we have had some unsavory person decide to inject some malicious code into our old site so, its time for a change! Bear with us whilst we get things back up and running.
