Filling gaps of occurrence data for Colombia: case of birds

Biological databases from collections, museums, and inventories present gaps and biases as some species and geographical areas remain poorly known. Biological expeditions are thus crucial to increase the knowledge of biodiversity and should be planned carefully. Using 1-km2 spatial resolution, this dataset provides which locations of Colombia that have been surveyed at least one time for the bird group. <br> The first two columns describe the latitudinal (lat) and longitudinal (long) coordinate of the locations. Meanwhile, the last column (observed) describes whether the location has been surveyed at least one time, e.g., if the location has at least a point record, its value is 1; otherwise, its value is 0.
