I am not perfect, my wife will tell you that in abundance and yesterday I realised just how rubbish I am....I was sent a LiDAR capture of some woods and no matter what I did, it wouldn't render in the right place. I knew the cloud was captured in EPSG 27700 (British National Grid) using … Continue reading Give #LiDAR files a coordinate system with no GIS

Making Heightmaps
Published in xyHt October 17 2017: http://www.xyht.com/spatial-itgis/making-heightmaps/ So there is no hiding it, I've been building a lot of 3d data recently, partly to sell, partly to fuel my adventures into augmented reality (if your interested in me adding this to the blog, please say!).

The Problem with 3D GIS
3D GIS is game changing, it can change the way you view your analysis, it can provide insights which you may have overlooked….but there is a little problem which I may had not shared in my deluge of blogs about how great 3D GIS is….. ...Sometimes it can be hard work.

Add OSTN15 to QGIS 2.16
As you may be aware, the United Kingdom has a new transformation model that is OSTN15.....But why? What does it mean to the geospatial community? Without being too nerdy, tectonic plate movement means that the "model" surface (the geoid) is slowly moving from best fit for the coordinate system.

Using 3D Web Mapping to Model Offshore Archaeology
Ever since I started working in the renewables industry on offshore wind farms over 8yrs ago and had to analyse shipwrecks, I thought about how much more interactive and informative shipwreck analysis would be in 3D. There are many companies out there at the moment who produce the most amazing visualisations, where is the ability … Continue reading Using 3D Web Mapping to Model Offshore Archaeology
How to Grayscale ArcGIS Pro Vector Symbology

We all know that it has it's 'unique-ness' about it, after using it for a few years you start to ask "why don't they do this...." or "How … Continue reading How to Grayscale ArcGIS Pro Vector Symbology
Do your work right and you can be smart too
Originally published in xyHt Ever since I saw the word phrase "smart city", I have cringed. Not because of the term but what it alludes to.
