In raster calculator use the double asterisk ** for exponentiation. With vectors, in field calculator use the caret ^ for exponentiation. Continue reading “ArcGIS pitfall of the day: exponentiation with rasters and tables”
I just stumbled upon an excellent summary on OSTN02 over at Nicolas Duggan’s blog. EDINA have documented how to install and use OSTN02 in ArcGIS, so no excuse anymore for not using OSTN02!
At the University of Manchester we use Concurrent Use licenses for ArcGIS. For working offline, e.g. for fieldwork, users can borrow ArcGIS licenses onto their laptops while are on the university network or VPN, and then use ArcGIS for a certain length of time while offline. Continue reading “How borrowing a concurrent ArcGIS license works, and how it doesn’t”
Thanks to the European Commission’s INSPIRE directive and the UK OpenData initiative the UK Environment Agency makes many of its datasets publicly available. You can load this data over the internet directly into ArcGIS and other GIS software.
Sometimes you have access to data through a WMS service, but you want the data as vector features. In this post I show how to extract vector features from a WMS layer using ArcGIS Desktop.
TAS (Terrain Analysis System) is a software for geomorphological terrain analysis developed by John Lindsay during his time at Manchester University. John has now moved on to his next project, Whitebox GAT, but we still use TAS for various tasks. This is how to get elevation data from TAS into ArcGIS: Continue reading “Convert rasters from TAS to ArcGIS”
Update: Google have made GE Pro free for all users – thanks Google. The post below is now obsolete.
Recently I had a few inquiries from students, academics and IT staff who had heard that as a member of a UK university you can get Google Earth Pro for free. This is to clarify: Continue reading “Google Earth Pro for UK Higher Education”
