This application is primarily intended to map TheThingsNetwork reception reports in a Google Sheet. However, it can be used with any sheet containing latitude and longitude columns.
To use this app, enter the URL of a Google Sheet spreadsheet which has columns latitude, longitude, and optionally gatewayId. Each row will be converted into a marker on the map, where every column will be displayed as a line on the marker's description, and finally TheThingsNetwork gateway IDs will be mapped and added as points with lines from each reception report that they "own".
