Learning outcomes

On successful completion of this module students should be able to:
1. Identify and acquire a range of secondary spatial data sources of relevance to the geographical, earth, and environmental sciences

2. Convert analogue spatial data to digital spatial data within a GIS framework

3. Acquire georeferenced spatial data in the field using DGPS

4. Acquire and interpret subsurface data using GPR techniques

Brief description

The first part of the module will deal with issues relating to the acquisition of secondary datasets (both analogue [e.g. maps and aerial photography) and digital [e.g. Digital maps, DEMs, LiDAR). The second half of module will provide students with training in the acquisition of primary datasets using surface topographic survey (total station and differential GPS) subsurface (GPR) techniques.

Content

The main themes covered in this module are:
  1. Types and sources of secondary spatial data - maps and map projections, aerial photographs and LiDAR (1 week)
  2. Acquisition and processing of spatial digital data - Landmap and Digimap (2 weeks)
  3. Converting analogue spatial data to digital spatial data - map and AP digitizing techniques ( 2 weeks)
  4. Land survey techniques - total station (1 week)
  5. Land survey techniques - DGPS (2 weeks)
  6. Sub-surface surveying techniques (2 weeks)
