Strictly Spatial 22a2


Have you wondered how quickly datums can become incorrect? Or have you ever been stuck wondering what type of map is best to display your data? In this fortnight’s Strictly Spatial we look at both of these, as well as handy holiday applications and maps of movie locations. Read on for more!

Every day we work with spatial data and take things such as projections, coordinate systems and datums for granted. We don’t often think about the tectonic processes that shift, change and mould our earth and affect our datums. Australia is currently in the process of designing a new datum for mapping and spatial data. The current Geocentric Datum of Australia 1994 (GDA1994) has served them well but it is now a surprising 1.5m out! You can read about the new datum on Esri Australia’s blog here.

When creating a map you need a few things, firstly data. Once you’ve got that sorted you need to decide how to display the data. Should it be a choropleth map? How about a dot density? Or even a cartogram? To help you decide you can take a look at the UX Patterns for Maps website. This website contains a range of different cartographic map styles ad explanations about how and when is best to use them.

Strictly Spatial 22b3Remote Sensing comes in various degrees of ‘remoteness’. From ground based infrared sensing, to drones, to Geosynchronous satellites. These different methods all have their own advantages and disadvantages. Esri has written a blog post outline the previously mentioned, as well as other, remote sensing platforms.

We all enjoy a holiday and in today’s connected world it's often difficult to escape technology. However, there are some handy apps that can help make sure that you make the most of your break. The team at the Geoawsomeness blog have made a list of five ‘must have’ location based apps that will prove invaluable on your holiday. Check them out here.

Everyone loves a good movie and for the more diehard fans you could think of nothing better than visiting a location used in your favourite film. Whether its exploring your favourite Hobbit Hole, walking down Diagon Alley or visiting the hall where Stu explains GIS in What We Do in the Shadows. Google Maps Mania has published a blog post that introduces a number of maps showing where movie locations are in various cities and countries. You can check the blog post out here.
