Satellite Data Overview

There are a number of qualities and characteristics to consider about satellite data and types of satellite orders. These include the Spatial Resolution, the Temporal Resolution and the Available Bands.
The temporal resolution of a given dataset is quite simply how often it is collected, or in other words, how fine-grained it is in terms of time. High-revisit systems such as Planetscope can be said to be of high temporal resolution, whereas low-revisit systems are of low temporal resolution.
The bands available on a given satellite help to determine what kind of analysis can be performed on it. Please see the later article for more information on what bands Graniot provides.
Satellite data available through Graniot comes in three main spatial resolution categories:
This is data from Sentinel 2, and is provided at 10 m (pansharpened) resolution for the majority of outputs. It is most useful for large area monitoring, and to watch trends over time, has been around for a long time.
This is data from satellites such as Planetscope, and is generally around 3 m in resolution. This data is well-suited to agricultural applications, and is a popular option for commercial optical data.
High resolution data includes data from satellites, like SkySat, with resolutions ranging from 0.5. This data is very well suited to infrastructure monitoring, urban monitoring, use cases that require high quality optical outputs and where further analytics require the higher resolution.
Our other high resolution sensors available include:
- Pleiades | 0.5 m/pixel
- Beijing-3 | 0.5 m/pixel
- SkySat | 0.5 m/pixel
Very high resolution data includes our Pleiades-Neo satellites, with resolutions from 0.15 m to 0.3 m. When you are wanting to view details on a surface, such as vehicles, roads, small buildings, and trees, this data product will be our best recommendation. Pleiades-Neo also comes with 6 spectral bands.
