Pre-Processed Data

Overview of the pre-processed data products.

Updated over a week ago

Introduction

The pre-processed data products allow you to upload already processed orthomosaics and point clouds to the Sitemark platform. You can use them to add different types of data to your existing sites (3D scanner, Lidar, Satellite) or to get access to the Sitemark platform to share, analyse, and collaborate on your own processed drone data.

There are three products to choose from:

  • Visual (RGB) Orthomosaic: allows you to upload a single visual orthomosaic. Can be used to upload self-processed visual inspection data or satellite data.

  • Point Cloud: allows you to upload a single point cloud. Can be used to upload a 3D scanner, Lidar, or self-processed survey data.

  • Point Cloud + Visual (RGB) Orthomosaic: allows you to upload a combination of a point cloud with a visual orthomosaic. Can be used to upload self-processed survey data with 2D and 3D visuals.


Orthomosaics

We currently only support visual (RGB) orthomosaics. The file should be 3 or 4-band GeoTIFF. It should be a geo-referenced orthomosaic because we need to be able to position it on the globe.

To be safe, you must rely mostly on the EPSG coordinate systems. A single dataset allows files up to 20 Gigapixels. When going over that limit, multiple datasets will be consumed.


Point Clouds

We support all kinds of point clouds, ranging from RGB to black-and-white, like 3D scanners or Lidar. Only LAS files are supported at the moment. It should be a geo-referenced point cloud because we need to be able to position it on the globe. To be safe, you must rely mostly on the EPSG coordinate systems.

A single dataset allows up to 100 million points. When going over that limit, multiple datasets will be consumed.

To get an idea of how much data you would use, you can use the following rules of thumb:

  • 1000 drone photos would generate a point cloud of around 8GB
    Please note that this is quite heavily dependent on the processing settings.

  • An RGB point cloud with 100 million points will be about 3GB

Many factors can influence the size, so your 3GB point cloud might contain much less, for example. We're working on a simple tool you can use to check the size of your datasets.
