Raster functions have been around in ArcGIS Pro for some time now. They work slightly differently to traditional raster data processing. Instead of writing out a new raster image with each step, they create a virtual raster (that only exists “in memory”) which is calculated based on the input raster(s) values. This allows output to be created very quickly. Some functions require Spatial Analyst (SA) or Image Analyst (IA) extensions, while others are available without extensions. A full list of the Raster Functions can be found here.

For this example, I used some Sentinel 2 imagery which can be downloaded from the Copernicus Open Access Hub. I then loaded some of the image bands to ArcGIS Pro. Go to the Imagery tab and click Raster Functions. This will open the Raster Functions Pane. Expand Math and choose the Calculator function. (Note: Calculator requires SA or IA extension).

This will open the dialog for the Calculator. It allows you to define raster data or layers as variables and then use those defined variables to construct an algorithm.

In this example, I am doing a simple ratio between Sentinel 2 bands 12 and 8 (these are similar wavelength ranges to Landsat TM7 bands 7 and 4). Once a variable is defined in the calculator, it will appear in intellisense (you can see the popup in the image below showing b8 and b12 as options), along with various other available mathematical functions.

Once you have completed the formula, it is possible to either create the result in the current map “in memory” or save it out as a permanent raster file.

Click Create new layer to add the resulting processed image to your map.

It is then possible to create a series of ratio images and make a composite of those ratio images. This can highlight features of interest to your study.

The image below is RGB Sentinel2 band ratios 4/3, 11/3, 12/8 (Landsat TM7 band ratios 3/2, 5/2, 7/4). It was created using the Composite Bands raster function.

A few years ago, we published a free e-book entitled “Why Use GIS in Petroleum?”. With many thousands of downloads, it has become our most successful publication. People across the industry clearly value the concise overview of the Top 10 use cases for GIS in Oil and Gas. 

As time is moving on, our venerable publication may be due for an update. While we consider how to revise it, this blog post shares some thoughts and trends we’re seeing in the industry – and we are keen to hear your views as well (see below, it involves a prize!). 

A new breed of digital workflows 

Recent Petroleum User Group (PUG) events in Houston and London showed that most oil and gas organisations have now embarked on digital transformation, or ‘digitalisation’. Equally there remains an enduring need for things like good data management or analytical skills. 

Of course, our industry has been digital for decades. Digital transformation is no longer about making things digital that weren’t digital before, like replacing hand-drawn maps with GIS. Today, thanks to the relentless progress and versatility of computing platforms, it’s about re-imagining geospatial workflows from the ground up. 

True digital transformation goes beyond optimising the mere ‘business as usual’. And companies who are willing to experiment are most likely to reap the biggest rewards. This is evident in areas such as machine learning, where you won’t know what you’ll find until you find it – from accident hotspots hidden in well supply traffic data, to geological analogs buried deep in corporate document libraries. 

The enduring role of GIS 

GIS has always been good at many things but, in this brave new digital world, one of its most enduring features is the ability to join up data silos. In our industry, the ingestion of data from multiple sources into a single view remains one of the most challenging and rewarding problems. 

Organisations who successfully implement spatial integration reap significant benefits. From digital maps to operational dashboards, from scientific analytics to business intelligence, GIS simply helps people make sense of data – whatever the source or format. 

But of course, the way GIS works has evolved too. Thanks to the latest advances in platforms, sensors, analytics and visualisation, GIS is now offering entirely new ways of working. Why spend days interpreting imagery when an algorithm running in the cloud can do it for you in seconds? Why slave away in an office cubicle when, in a few clicks on your phone, you can create your report out in the field? Why decipher complex maps or cross-sections when you can visualise everything in 3D? 

Take the survey 

These are just some of the thoughts on how we think GIS has evolved over the past few years, and the opportunities this now offers our industry. At the same time, we’ve seen persistent demand for services like spatial data management and GIS training. 

What do YOU think? We’d love to hear from you. Take our 3-minute survey to share your GIS priorities and aspirations. We’ll post the results on our blog and, in return for taking part, you’ll be entered into a draw to win a copy of Esri’s fabulous new 500-page book on modern cartography. 

As they say, you have to be in it to win it. Good luck!!

Getech, providers of natural resources exploration data and expertise, have released a new Regional Report Online.

The Report uses a Story Map to summarise an assessment of the potential effects of the end-member plate models on the hydrocarbon prospectivity of the Southern Caribbean margin, and has been included in this year’s Esri Map Book.

The featured part of the Getech Regional Report shows the geologic structure interpreted from gravity and magnetic data across the area.

Structural features were mapped from gravity, magnetic, Shuttle Radar Topography Mission (STRM) and Landsat data.

The example shown is a band pass of the isostatic gravity on which the structures are interpreted. Following the mapping of the structures, features were given activation histories from information gained from seismic data and/or literature. The structural evolution of nineteen basins are included in the report, their intrabasinal features are illustrated, and their structural evolution described.

In August 2018 Mr Timothy Kabba was appointed as Director General of the Sierra Leone Petroleum Directorate. Mr Kabba brings fresh perspectives to the current Fourth Sierra Leone Licensing Round and in step with the Government’s New Direction initiative, he has decided to expand the dialogue and enter a period of industry consultation.

This consultation process is expected to last for up to 6 months and requires the temporary suspension of the ongoing Fourth Licensing Round.

Mr. Timothy Kabba, Director General of the Sierra Leone Petroleum Directorate commented: “The Republic of Sierra Leone is committed to attracting long-term investment through the development of its natural resources. The Petroleum Directorate’s mission is to deliver this investment through a process that creates maximum value for both the investor and the country’s people. I look forward to meeting with the industry during this important consultation process”

Jonathan Copus, CEO of the Getech Group commented: “The offshore waters of Sierra Leone contain proven petroleum systems and the country’s Fourth Licensing Round has generated significant levels of interest. This has led to a busy and wide-ranging dialogue with a variety of high-quality international oil and gas companies. Through a process of consultation, the staff of the Petroleum Directorate and Getech will work in partnership to narrow and focus the License Round conversation – the shared goal being the successful conclusion of that Round.”
