Study Notes
Categorization of Environmental Impacts
- Environmental impacts can be categorized into primary and secondary impacts.
- Primary impacts are those directly attributed to the project.
- Secondary impacts are indirectly induced and include associated investment and changed social and economic activities.
Overlay Mapping Technique
- Overlay mapping is a simple quantitative technique used to predict anticipated impacts.
- It involves using a base map of the project study area and overlaying different soil or geologic features or particular impact concerns.
- The technique identifies where overlaps of particular concerns occur.
Methods of Overlay Mapping
- Hand-drawn maps can be used for overlay mapping.
- Computer-generated maps can be used for overlay mapping.
- Geographic Information Systems (GISs) can be used for overlay mapping, which is an advanced technique.
- GIS is a valuable tool for assessing cumulative impacts and is increasingly being used in impact studies.
