GPS Waypoints is a multi-purpose application that has being used in various professional and personal surveying activities. The tool is more oriented to land survey and mapping usage although it can support other use cases. The main 5 use cases supported are described below:
- Land survey and mapping – users can make field surveys by collecting points (Add Waypoint), classifing them with the relevant tags and exporting all data to a CSV/KML file to be further analysed in a laptop using a geographical information tool.
- Plan and find places – users can Import Waypoints through coordinates or addresses and obtain directions and distances to the place using the Get Me There feature
- Define land areas for geoplanning – users can create areas on the field (Create Path Polygons), check areas and perimeters and export polygon to desktop
- Define routes for geoplanning – Users can create a paths (sequence of points) on the field (Create Manual/Auto Path), check areas and perimeters and export multi-lines to desktop (alternatively create a route with multiple Waypoints with tags)
- Track a moving activity – Users can track a moving outdoor activity (Create Auto Path) and export it to a GPX file to be further analysed
The land surveying activities depends on the accuracy of the GNSS receiver being used. You can use a internal receiver (medium accuracy positioning) or an external receiver (higher accuracy). The application becomes particular relevant in activities when it is needed to collect data widely and fast, such as with the involvement of volunteers.
The professional activities covers professionals from various sectors (not only geographers), typically to perform land surveying, land areas and routes definition. Some real case studies in agriculture (plantation planing, infestation monitoring), real state (measure property areas), emergencies (disaster mapping), urban planing (mapping validation) and infrastructures (road maintenance) are presented hereafter.
The GPS Waypoints is being used in Agriculture on both planning and monitor cultivated areas. It is used to measure new crops areas for planning the next season and estimate production (create Manual Paths/Polygons), measure and plot new tubing layouts for the future expansion of sugar mapple trees pipes (create Manual Paths), identify and classify the infested trees on olive groves (Add Waypoints with custom tags).

The tool is used in Real State to measure land properties by owners, evaluators, etc… It can determine areas and borders of land properties for planning and valuation purposes. The user must collect sequential points of the land surroundings (Add Point to Path) and close the path to build an polygonal area.

The tool is used in Urban Planning to validate thematic maps of urban areas. The user collects the validation points on the field, tags them using his mapping classification system and exports the results to a desktop for validation of classes and determination of the mapping accuracy.
Useful in emergencies with the support of volunteers to map and classify the object found on disaster area. By collecting the points where the wreckage and other objects were found, GPS Waypoints can help you by providing accurate coordinates and create disaster mapping.

A known infrastructure use case is the road maintenance classification. The maintenance professionals need to evaluate and classify the road status. They can identify pavements distresses with exact coordinates of the failures and associate a tag based on their own classification model. The model can be adapted for each country, using different levels of detailed. For instance, pavement distress model for asphalt concrete surfaces could be as simple as:
Patching and Potholes
GPS Waypoints can also be used for personal entertainment, like outdoor activities, geocaching, travel and other non-professional activities. This application enable easier orientation on map by adding, tagging and exporting the Points of Interests (POI).

Meet me here
GPS Waypoints is convenient for mass market users to save their Points of Interests (office, home and other typical meeting places) and share their locations with someone else (they want to meet) via any messaging application e.g. SMS or E-mail. The meeting person can check the place clicking on the shared URL with place location and check the PoI address (geocode feature). Furthermore, a user can easily send someone else their current location to be found (Find me).
