Building a Digital Twin within the ArcGIS Platform – Part I

Many organizations are interested in the ‘Digital Twin’ – a computer-based replica of a physical asset onto which other data can be layered to derive insight: from understanding the asset’s current status to modelling potential changes. The scale of the asset being modelled can vary – in this project we’re looking at individual buildings, but the concept can be extended to the scale of a city and beyond – the live traffic data layered upon the digital road…

My 5 Favourites Features in Exploration Analyst for ArcGIS Pro v2

Four things you didn’t know about our ArcGIS Pro training

2020 is the year when people are finally “going Pro”. Many of our customers have been running ArcMap and ArcGIS Pro in parallel for some time. But in the last few months we have seen a marked increase in the pace of companies migrating from ArcMap to Pro.   At Exprodat we have also experienced this with a busy start to the year with our ArcGIS Pro training courses, and especially our virtual training offering. Anyone who’s made the transition from ArcMap to…

When scale bars don’t scale

Traditionally, scale bars are based on the origin point of the map’s coordinate reference system (CRS), commonly the intersection of the equator and Prime Meridian. Many users don’t realise that the scale bar may be inaccurate due to the distortions that occur with any map projection.  In ArcGIS Pro, this inaccuracy can be reduced with the “Compute at center” property, though not entirely corrected for every map     Not all…

How Tectonic Motion is affecting your Map Accuracy

On our dynamic Earth, continents don’t sit still. They slowly move around the planet, stretching oceans and lifting mountain ranges. Sure, it’s not like you risk being overtaken by Africa on your commute. Tectonic movements average a couple of centimetres per year – about the same speed as the growth of your fingernails.  But over time, things add up. And it’s beginning to impact the accuracy of geospatial data.    Why your maps are probably out of place  Every map…

Exploring New Frontiers at GRSG Frascati ‘19

In December 2019 I had the great pleasure of attending the 30th Anniversary Conference and AGM of the Geological Remote Sensing Group, which was held at the European Space Agency offices in Frascati, Italy. The conference presentations and delegates nicely represented the history of geological Earth Observation (EO) during the lifetime of the group. There were fascinating…

The Pelican Energy Transition

In the last eight years, Esri users around the world have created nearly one million Story Maps to share their work and ideas. Telling stories has always been an effective way of keeping an audience interested and by creating the Story Maps technology, Esri has made it easier for everyone to take advantage of this…

Getech sponsors Imperial College MSc project investigating Santos Basin prospectivity

Getech, the natural resource exploration specialist, continues to support Imperial College students with projects that contribute to their MSc studies. This year’s Petroleum Geoscience MSc project was undertaken by William Jewell, who was tasked with using play-based exploration assessment techniques to review the hydrocarbon prospectivity of the offshore Brazil Santos Basin. The starting point for…

Identifying Onshore Surface Seeps with Satellites

Reducing exploration risk by confirming petroleum source and charge is a major component of petroleum system analysis and is a critical phase of any exploration program.   The use of cloud-penetrating radar data in offshore basins to detect and isolate slicks emanating from sea floor seepage of oil and wet gas is now seen as…
