Nowadays, amateur drones have an amazing range of applications. You may wonder: “Can I use my drone for photogrammetry?” and the answer is “Yes”. In this tutorial, you will create a georeferenced and measurable 3D model, using YouTube video captured by DJI Inspire 1 using Agisoft PhotoScan and view it with Sputnik GIS Source video (4k / 2160p): 3D Model created using Agisoft PhotoScan: If you're interested, you can read a tutorial. Sputnik GIS also used to measure distances and heights, calculate cut and fill volumes of piles and quarries and volume differences between digital elevation models obtained at different time, generate cross-sections (profiles) of DEMs and export them to DXF.

Então, eu consegui as coordenadas dos pontos de um database, mas por algum motivo quando plotei elas no mapa algumas ficaram muito longe do local que deveria. No começo eram mais de 600.000 pontos, depois de filtrar algumas acabamos com 490.000, mas mesmo assim algumas continuam muito longe (casos de o ponto estar 300m longe da cisterna). Entao pensamos que a melhor maneria de saber exatamente o local era por sensoriamento remoto
