OS 3D GIS Urban Canyon GNSS

Improving GNSS in the Urban Canyon

To prepare you for the this blog post, I wish to point out that I am a geospatial expert and can hold my own around the ins and outs of survey, so going to an event at the Ordnance Survey on “3D mapping for the improvement of GNSS in urban areas” was an eye-opener. You...

BigSUR

A software team creates a large-scale, structured, urban reconstruction system that handles multiple data sources with deep learning. Today, big data is ubiquitous: we have more information than ever, but combining and understanding all this data has become the challenge. This is particularly true for 3D cartography as we view our continually changing world with...

Esri CityEngine: What Is It?

These past few weeks I’ve been trying to do some clever augmented reality stuff with Unity involving putting an object on the floor and ensuring it doesn’t wobble when you walk around it. (Yay for SLAM in mobile devices.) Although in software like Unreal and Unity you can download or buy models, what do you...

Radiant Earth

Connecting the global development community to Earth imagery and primary analytical tools. Nonprofits working on global development issues have had great difficulty acquiring and using a staple source of geospatial data in the form of Earth observation imagery collected by satellites. Anne Miglarese, the founder, and CEO of Radiant.Earth is working to change this. Miglarese...

Using OpenStreetMap Basemaps with QGIS 3.0

QGIS 3 is a new wave of open source GIS. Not only is it extremely quick and efficient, allowing you to use almost every type of geospatial data you can throw at it, but it also includes a 3D renderer and ways to export your creations straight to the web. And let’s not forget the...

AIS: Using Shipping Data in GIS

We’ve all been dazzled by those awesome maps that animate ships or aircraft using AIS, as they move in near real time, but how do they work? What magic sits beneath the hood? As luck would have it, whilst working with the offshore wind farm industry I had to do a lot of vessel analysis,...
