This page contains information about a number of guides to help you undertake common GIS operations, and a table containing the guides in downloadable PDF format.

Georeferencing an image

Some raster GIS layers will arrive as a picture that is not referenced to a location on the Earth's surface. This guide takes you through the steps to reference a raster image (like an aerial photograph) to a pre-existing layer with the correct coordinates.

Creating process diagrams

Often data is processed and manipulated when using GIS and these processes need to be documented and recorded. This guide shows you how to create a simple processes diagram to document changes using Visio.

GIS-shapes

The GIS-Shapes file is a set of common shapes that are used in Visio when creating a process diagram.

Transferring data to and from GPS units

Often you want to transfer data from points you have collected in the field into a GIS environment or simply download the points onto your computer. This guide shows you how to do this and how to upload data to a GPS unit.

Mapping a network drive in windows

If you are unable to access a drive to search for datasets you need, the drive may need to be mapped first. This guide takes you through the steps needed to create a connection with the drive.

Transforming (converting) coordinate systems in ArcGIS

There are a huge number of possible coordinate systems. Your GIS data may need to be reprojected to align properly and this guide takes you through the appropriate steps.
