Exprodat’s “Team GIS” walking team would like to thank all who generously supported them to help raise over £6,000 Oxfam in completing Oxfam’s Trailtrekker 2011. Most of the team completed the 65 km silver course in just under 14 hours. The one team member that did not last the distance completed 39 km over the hardest…

Using the ArcGIS Correlation Coefficient

Investigating the Correlation Between Formation Pressure and Depth using ArcGIS Determining whether or not two or more continuous variables are correlated in space or time and quantifying the nature and the strength of this correlation is a type of data analysis which is common in many fields including physical geography, environmental studies and earth sciences.  In…

Tip 17: Reselecting Highlighted Features

In ArcGIS Desktop selecting features is often an essential step before copying, modifying attributes, changing geometry, or merging features.  But when using layers with multiple overlapping polygons it’s often not easy to select the polygon you want. Let’s assume that I have a layer with many overlapping polygons and I want to select a particular…

The event is a 65km trek for teams of 4, run over 30 hours across the Yorkshire Dales and includes more than 1500 metres…

Tip 16: Polygon Editing

We often need to use editing tools for digitising a new object such as a point, line or polygon feature. These are fairly straightforward to create, but one of the problems with polygons is that we sometimes need to create a new one alongside an existing one. Let us suppose we have a scanned map…

Seismic 2D shot points in ArcGIS 10

For a while now Esri’s ArcMap has had the ability to add ‘hatches’ to line layers, enabling you to post labelled measurements along lines (for further information see the ArcGIS Desktop 10 help on linear referencing and dynamic segmentation).  The main applications of this in oil and gas are posting shot point labels along 2D…

Exprodat Holds the Key to the KINGDOM for ArcGIS Users

Exprodat’s KBridge was released today for Esri’s ArcGIS 10 platform, continuing to meet the demand for  low cost data integration between KINGDOM and ArcGIS. Geoscientists using KBridge can take control of transfers between SMT’s KINGDOM and ArcMap rather than rely on expensive service-oriented integration solutions. KBridge allows geologists and geophysicists to transfer KINGDOM project data…

Tip 15: Exporting PDFs

Although there are numerous formats for exporting your finished map to, Portable Document Format (PDF) files are possibly the most useful. These files allow users to share high quality cartographic outputs with both a level of security and some flexibility of display. It is also a popular format for delivery to commercial printers, for sharing…

Extruding data in ArcGIS Explorer 1500

In a blog last year we posted an ArcGIS Explorer 1200 add-in that allowed you to create 3D KML representations of feature layers. We have now updated the add-in for ArcGIS Explorer 1500 and posted it for download @ Esri’s ArcGIS.com site. For further information see the following resources: 3D Extruder add-in User Guide for ArcGIS Explorer 1500 Ross Smail’s original…
