The present tiger census, the data was collected using an Android based application – M-STrIPES (Monitoring system for Tigers’ Intensive Protection and Ecological Status) and analyzed on a desktop module. This greatly eased out analysis of a large quantum of data that was collected for over 15 months involving survey of 381,400 square kilometers of forested habitats, 522,996 km of walk by forest officials and laying of 317,958 habitat plots.

Besides cameras were placed in 26,760 locations which provided a total of 35 million images of wildlife including 76,523 images of tigers. These images were segregated in a short time using artificial intelligence software. In fact, 83 per cent of the tiger population images were captured wherein 2461 individual tiger photographs were obtained while only 17 per cent of the tiger population was estimated using robust spatially explicit capture re-capture statistical models.
