In the UK students and staff in Higher Education can get boundaries of Lower and Middle Layer Super Output Areas (MSOA / LSOA, a sort of census boundaries in the UK) from the UK Data Service Census Support. Continue reading “How to make LSOA and MSOA boundaries from UK Data Service align properly in ArcGIS”
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”
Yesterday I had these ArcGIS queries from users:
- “I’d like a parcel to have a grid on it with each square measuring 2×3 meters….. is there a way of doing it other than manually?”
- “I want to do random spatially stratified sampling and to delineate my strata I want to put a regular grid over the study area. How can I do that?”
Both these tasks can be solved with the Create Fishnet tool. This tool is suitable for zoning any area into regular rectangular divisions. Potential applications include:
- creating Search and Rescue zones or assessment zones (thinking of MapAction)
- create a systematic sampling grid
- create a reference grid
A similar tool is the Grid Index Features tool, this is used to create an index layer for ArcGIS Data Driven Pages.
If you are using TAS, the Terrain Analysis System on Windows 7, the Help function does not work. To fix it: Continue reading “Quick Tip: get Help in TAS working”
