In outdoor exploration, tools such as high-definition satellite maps, GMap, and GEE historical maps can help self-driving travelers find camping spots, wild fishing spots, and query information such as water levels and underwater structures more conveniently. This article explains how to use these tools to help with your self-drive outdoor adventures.
1. HD satellite map
A high-definition satellite map is a map that shows the surface of the earth through satellite images. In self-driving tours, high-definition satellite maps can help travelers understand the destination's landforms, topography, and landscape information. In addition, high-definition satellite maps can also be used to plan routes, find camping spots, wild fishing spots, etc.
When using high-definition satellite maps, it is recommended to use well-known map services such as Google Maps and Baidu Maps. These map services will continuously update and optimize satellite imagery to provide clearer and more accurate map information.
2. GMap and GEE historical maps
GMap and GEE (Google Earth Engine) are two powerful map tools. GMap is an online map service that can be used for route planning, navigation, etc. GEE is an earth observation platform based on cloud computing, which can be used to analyze satellite images, query historical maps, etc.
When using GMap and GEE, it is recommended to understand their basic operations and functions first. For example, how to search for a destination, how to plan a route, how to adjust the map scale, etc. In addition, you can also learn how to use the historical map function of GEE to query the map information of different time points of the destination.
3. Find camping spots and wild fishing spots
In the self-driving tour, finding camping spots and wild fishing spots is an essential link. When using high-definition satellite maps, GMap and GEE historical maps, you can follow the steps below to find camping spots and wild fishing spots:
- Use high-definition satellite maps or GMap to search for clearings or rivers near your destination. Suitable locations can be found by keyword search or by manually zooming the map.
- Use the GEE historical map function to query the map information of the selected location at different time points. For example, you can query the map information in the past year to understand the vegetation cover and water level changes of the location.
- Based on historical map information and field survey results, evaluate whether the selected site is suitable for camping or wild fishing. For example, if the selected site has a lot of vegetation cover in the past year, it may need to be excluded; if the water level is too high or the underwater structure is complex, it also needs to be carefully considered.
- According to the evaluation results, choose a suitable camping spot or wild fishing spot. When choosing, you also need to consider safety factors and the advice of other travelers.
4. Query water level and underwater structure
Knowing water levels and underwater structures is very important in wild fishing and outdoor adventures. When using the GEE historical map function, you can query the water level and underwater structure information at different time points. Specific steps are as follows:
- Use GEE's spatio-temporal dataset function to select a suitable destination and time range. For example, you can select a river or lake near your destination to query information about water levels and underwater structures over the past year.
- By analyzing satellite imagery and remote sensing data, query the water level and underwater structure changes of the selected location in the past year. Data analysis and processing can be performed through the tools and algorithms provided by GEE.
- According to the query results, understand the changing trends and rules of the water level and underwater structures of the selected location. For example, you can understand how the water level changes in different seasons and weather conditions, as well as the changes in underwater structures, etc.
- According to the query results, adjust wild fishing or outdoor adventure plans. For example, if the water level of the selected location is too high or the underwater structure is complex, it is necessary to re-select a suitable location or adjust the expedition plan.
In short, tools such as high-definition satellite maps, GMap, and GEE historical maps can help make self-driving outdoor adventures more convenient and safe. When using these tools, it is recommended to understand their basic operations and functions first, and use them flexibly according to the actual situation.
