Right to keep and bear arms? The topic of firearms control and gun violence is one to approach with caution, given one, the fatalities involved, and two, that in the USA particularly, it can often stir strong debate and emotion on either side. However, following (another) mass shooting at Marjory Stoneman Douglas High School in Florida and the perhaps unprecedented public demonstrations following this in USA, and around the world, as part of ‘March For Our Lives’ – it is a topic which is hard to ignore. With the aim promoting tougher gun control legislation and raising awareness of gun violence, it has brought the debateRead More →

Okay, now I want to get coding… In the previous posts in this series, we have looked at the intuitive ‘out-of-the-box’ web maps you can configure with little to no coding knowledge, whether that be with CARTO or ArcGIS Online, with differing level of learning curves. This may be all you require and provide a timely and quick web mapping solution, particularly in the latter example, one that is integrated with your organisation’s/personal GIS infrastructure. However, to begin customising and ‘fine-tuning’ your web map to your exact needs, some knowledge or understanding of HTML, CSS, and a web scripting language, like Javascript, is required.

So I can make a web map, but I want more control… In my previous post, I introduced you to the world of web maps and how the world of geo web development has become more accessible for wanting to get started straight away in creating web maps with little to no web development skills, thanks to the intuitiveness of sites like CARTO. As explained previously, for many this is maybe all you are looking for or need, but others may want to explore options more integrated into existing offline GIS software, and get involved customisation and coding further. ArcGIS Online – Tailored for all levels IRead More →

That web map looks great! Wish I could make one… In some ways, there has maybe not been a better time to be involved in the geospatial and cartographic industry, whether as a profession or as hobby/passing interest. While ‘static’ maps and images of geographical information and data visualisation are still very relevant and useful, the rise of the interactive web map is an increasingly trend which is hitting the ‘mainstream’ more and more, whether it be through maps in current affairs like election maps, or through games or social media (e.g. Pokemon Go! and SnapMap). Therefore, the ability for cartographers and geospatialists to haveRead More →

Football is perhaps the true global game, but is it played on a level playing field, particularly economically? Most of you probably know the answer to this, but the relationship between performance and strength economically, and sporting ability and opportunity is still an interesting one. National team football is a better way to analyse this, given the great financial disparities in club football to buy the best talent and that national identity is a more static attribute. Now, I realise that some may love football/sport, some may loathe or have little interest for it. However, exploring the relationship between football and economics tells us something deeperRead More →

One of the things I’ve enjoyed so far in creating The Map Den, is being able to share some of the latest and interesting pieces of work and tips coming out of the GIS and mapping industry. The ‘science of where‘ community is alive and strong. However, it’s time I did some original mapping content myself. Today I’m starting simple, but nonetheless importantly, looking at global urban and rural population increases. Created through static maps created in ArcGIS and joining with population data from United Nations between 2010-2015, these maps investigate the continuing phenomenon of global population increase and the urban to rural shift. WeRead More →
