Creating a Multi-scale Geological Map

One of the key features of a GIS is the ability to view spatial data at any scale. To do this you need to understand what information should be displayed at what scale. This understanding is useful both for working within the GIS and for creating usable output, such as hardcopy maps or PDF map…

Esri PUG Papers 2000-2012

It’s nearly time for the 2013 Esri Petroleum GIS Conference, or “the PUG”. This year the conference is being held May 7-9, and is back in the George R. Brown Convention Centre in Houston, Texas. Last year before the conference I posted a blog that looked at the PUG papers back to 2009 and classified them…

Top 10 ArcGIS Printing Checks

Turn good maps into great maps by running some final checks before you print it out. In this blog I’ve put together a list of 10 things to check before printing from ArcGIS that ensure that my maps are as good as they can be. By way of an overview I’ve provided an annotated reference example map…

Tip 24: Successful Editing

For anyone new to ArcGIS, using the editing tools can initially appear a little tricky, and while delivering our training courses I sometimes hear people say the editing process is not very intuitive. In an earlier Exprodat tip (Tip 20: ArcGIS Editing Sessions) I looked at selecting editable elements and organising templates. Here are a…

Benchmarking GIS Performance

Benchmarking GIS Performance: A Multi-client Example In this blog, which follows a previous posting where I described a GIS Strategy Review Approach for the petroleum industry I’m going to look at a real world example of measuring GIS effectiveness: Exprodat’s multi-client GIS benchmarking project from 2012. If you’d like to jump straight into the detailed results please download the detailed 2012…

Measuring GIS Effectiveness

Measuring GIS Effectiveness: Exprodat’s GIS Maturity Matrix Approach How do you measure how well your company has implemented GIS? How do you benchmark your GIS both internally and externally against your peers?  How do you develop a strategy for developing your GIS, and measure how effective it has been? Exprodat developed the GIS Maturity Matrix to…

Plotting Dip and Strike Readings

Dips and strikes? Dip and strike readings are simple but important geological measurements which can be used for structural and stratigraphic analysis. They are generally made by a field geologist directly at a geological outcrop. The dip of the geological layer is defined as the maximum inclination, in degrees, of the layer from the horizontal…

Tip 23: Loading Grids to ArcGIS

As geoscientists, we need to bring into ArcGIS various types of gridded data, including surfaces with elevation values, sub-surface horizons with depth values, or imagery with spectral values. If you don’t have access to a dedicated ArcGIS extension for loading such data types, like our own Data Assistant, then the way to load these into ArcGIS…

Creating Map Books with ArcGIS

Increase mapping productivity using Data Driven Pages If you want to create a PDF map book or a map series covering a study area, you can do so with minimum fuss by using Data Driven Pages (DDP). The only thing you need to accomplish this is a polygon layer with a column which contains unique…

Stop Making Basic Positioning Mistakes!

Make a geodetic New Year’s resolution: stop making basic positioning mistakes! This New Year, why not resolve to stop making basic geodetic positioning mistakes in your ArcGIS documents. We’re sure your boss, customers and organisation will thank you. To help you with this, Exprodat and Priemere GeoTechnology have collaborated to create a free tool, called the Geodetic…
