The Importance of Offline Maps in Geospatial Field Work

In the world of geospatial data collection, the availability of technology has revolutionized the way we gather and analyze information about the world around us. The use of geographic information systems (GIS) and global positioning systems (GPS) has made it possible to map and analyze geographical features and spatial data with greater accuracy and efficiency. However, relying solely connected technology can have its drawbacks, especially when it comes to data collection in the field. This is where caching maps before going out into the field becomes crucial.

Caching maps is the process of downloading and storing map data on a device, such as a smartphone or tablet, for use in the field without an internet connection. This means that even if the device is not connected to the internet, the cached maps can be accessed and used for data collection. The importance of caching maps before heading out into the field cannot be overstated, and here are some reasons why.

First, cached maps provide a reliable backup in case of a connectivity failure. In areas with poor or no internet connectivity, relying solely on online maps can lead to significant data loss or errors in data collection. Caching maps ensures that data collection can continue uninterrupted, regardless of internet connectivity.

Second, caching maps can save time and increase efficiency. When data collectors have to wait for online maps to load or buffer, it can slow down the entire data collection process. By caching maps, data collectors can access the map data instantly, allowing them to focus on the task at hand and increase productivity.

Third, caching maps can help reduce costs. In situations where internet connectivity is limited, using online maps can result in significant cellular data charges. Caching maps eliminates the need for data charges, making data collection more cost-effective.

Caching maps before going out into the field is a critical aspect of geospatial data collection. It provides a reliable backup in case of connectivity failure, saves time and increases efficiency, and can reduce costs. With the importance of caching maps, it is essential for data collectors to prioritize the process before heading out into the field. Touch GIS makes this very easy!
