How to use Google Earth to plan safe routes through difficult terrains?

Analyzing Terrain Features

When planning a route through difficult terrain, it’s essential to analyze the terrain features to identify potential hazards. Use the “Terrain” layer in Google Earth to visualize elevation, slope, and aspect. Zoom in on the area to examine the terrain in detail, looking for features such as steep slopes, rocky outcroppings, and ravines. Identify areas where animals may funnel through, such as narrow valleys or gullies, and plan your route accordingly. Be aware of areas with loose or unstable terrain, such as scree slopes or talus fields, and avoid these areas if possible.

Identifying Potential Hazards

In addition to analyzing terrain features, use Google Earth to identify potential hazards such as water sources, game trails, and human activity. Zoom in on the area to examine the terrain in detail, looking for signs of recent or historical human activity, such as roads, trails, or campsites. Identify areas with abundant water sources, such as streams or lakes, and plan your route accordingly. Be aware of areas with high concentrations of game, such as feeding grounds or bedding areas, and plan your route to avoid these areas if possible.

Utilizing Historical Imagery

Historical imagery in Google Earth can provide valuable insights into seasonal changes and habitat use. Use the “Historical Imagery” tool to compare images from different seasons and years. This can help you identify areas that are used as feeding grounds or bedding areas, and plan your route accordingly. For example, you may notice that a particular area is used as a feeding ground in the fall, but remains vacant in the winter. This can help you plan your hunt accordingly, avoiding areas with high concentrations of game and minimizing the risk of detection.
