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…
Read detailsWe spend a lot of time working on our GIS analysis and then creating maps of our results. Eventually we need to do something with our map: present it; get it into a document; send it to another user. In ArcGIS Desktop (ArcMap) we can make a simple map output by using the menu option…
Read detailsHyperlinking allows users to establish a connection from one information source to another with just a mouse click. This can be very useful in presentations, and when applied to the GIS environment many forms of documentation benefit from a spatial linkage, e.g. in ArcGIS Desktop you can provide additional information about the features on the…
Read detailsIn today’s E&P industry the maxim “time is money” could never be more true. How much time is spent running the same process, the same workflow, clicking the same mouse buttons, tapping the same keys? Using GIS we have shortened workflows that take many hours into mere minutes, or from months into days. GIS tools…
Read detailsGeographic data is comprised of geographic features – such as wells, fields or licence areas – located by coordinates, referenced to the earth by a coordinate reference system (CRS). The management of geographic data is reliant upon understanding CRSs and successful management of the data’s CRS properties. The potential impact on oil and gas businesses…
Read detailsIn my last blog post I discussed the case for mapping the residuals in order to help us to understand the quality of the output of the interpolation of a continuous variable. In there I emphasized the importance of looking at the spatial distribution of the signed residuals to identify whether their spatial distribution may…
Read detailsAre you working in an organisation that you feel could really benefit from GIS, but don’t know how to go about selling it to the right people? Here are a few ways that I’ve found useful for promoting GIS to the decision makers: KISS – The key to selling any new concept to a busy…
Read detailsI want to create a complex custom symbol for use with area fills on a map. In ArcMap this can be done either with a multiple stacked marker symbol which is time consuming and difficult to construct, or using a small bitmap and importing that as a picture symbol. The problem with picture symbols is…
Read detailsESRI’s ArcGIS Explorer (AGX) is a free downloadable GIS viewer which allows viewing of a wide variety of spatial data in either 2D or 3D (Globe) display modes. This blog describes a utility I’ve developed that allows features in AGX feature or package layers to be exported to ‘extruded’ 3D KML (to download it see…
Read detailsAssessing the Quality of the Modelling of Continuous Variables in the 2D Domain – A Deterministic Approach See Part 1 and Part 2 of the ‘Measuring the Quality of Predictions’ discussion. Distribution of Uncertainty Unfortunately, limiting the analysis of uncertainty to the magnitude of the residuals alone is proven to be too limited an approach.…
