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.

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 →

Welcome to ‘Twin City’ Enter most towns, cities or villages in not just the UK, but in Europe and beyond, and you will likely find a ‘Welcome to [insert place name]’ and underneath ‘Twinned with [insert twin cities]’. Perhaps it is easy ignore these twin cities and linkages, or dismiss them as nothing more than symbolic, but what is the story behind twin or sister cities and what does it mean today? For those unaware a twin or sister city partnership is where there is a ‘friendship’ and legal/social agreement between one town or city (or even a region) to another , usually in a different country.Read More →

Fantastic bit of code and tutorial about aggregating point data for JSON objects using SQL. geomaticblog NOTE: I’ll use CARTO but you can apply all this to any webmapping technology backed by a modern database. Get all the data So we start with the typical use case where we have a one to many relationship like this: Easy peasy, we have a map with many stacked points. From here you can jump to this excellent post by James Milner about dense point maps. My example is not about having thousands of scattered points that at certain zoom levels overlap. Mine is a small set ofRead More →
