What is an UP42 credit?

An UP42 credit is the monetary unit used to price the use of data and services available on our platform (data and processing blocks, tasking and archive datasets, infrastructure costs, etc.). 1 UP42 credit is equivalent to 1 Euro or US dollar cent, and 100 UP42 credits are equivalent to 1 Euro or US dollar. For more information: Credits.

Restrictions

Is the access to data and analytics completely unrestricted?

UP42 aims to democratize access to geospatial information. Most of the free and commercial data and analytics are accessible to every user who is compliant with the UP42 Platform Terms and Conditions. However, restrictions apply to certain categories of data and analytics. For more information: Restrictions.

How can I get access to a restricted data block?

Before requesting access to restricted blocks, please make sure that your account details have been verified. For more information: Verification & Compliance.

EULA

What is the difference between streaming and download data?

The streaming data blocks can only be processed on the UP42 platform. You are not able to download the original dataset, but you can download the derived results after applying analytics, provided that the pixel values are not the same as the original dataset.

For example, users cannot download the outputs from the processing block Raster Tiling and Raster CRS Conversion. However, users can download the outputs from the processing blocks K-means Clustering and Raster Zonal Statistics. For more information: Download and Streaming Data.

Workflow

How can I create a workflow in UP42?

To create a workflow, add data and processing blocks, we recommend following the instructions from the tutorials below:

Can I process my datasets from storage?

Yes, datasets delivered to storage can be further processed on the UP42 platform. For more information: How to Process from Storage.

Job

How do I configure the job parameters?

First of all, it is necessary to be familiar with the JSON syntax and the name/value pairs. Before you start with the job configuration, please check out the example values from the article JSON Parameters and verify the requirements for each data/processing block. After adjusting the job parameter values, the estimated credit consumption of your job run is triggered before running the job. For more information: Configure Job.

What is a job ID?

A job is a unique instance of a pre-configured workflow that delivers the outputs. A universally unique identifier (UUID) is generated after running a job (live job or test query). This UUID (also called job ID) is very useful for troubleshooting job failures or viewing the generated outputs. To find the job ID, please go to Run Job.

Visualization

How can I view the images?

Currently, UP42 does not support the direct visualization of geospatial outputs. To render geospatial data and analytics, you need to install a third-party GIS software. For more information: Visualization in QGIS.

Why is my image blurry?

Your multiple-band raster is rendered with the RGB renderer in a GIS software and the alpha band is turned on. This alpha band is a transparency mask that provides a transparency value for each pixel. If you render the raster in QGIS, you can turn the alpha band off by going to Layer Properties and setting the transparency band to None in the tab Transparency.

Why is the spatial resolution of my Pléiades/SPOT 6/7 image lower than expected?

Geospatial data producers frequently provide low-resolution multiband images and higher-resolution panchromatic images of the same scene. Remote sensing datasets are usually delivered as more raster bands with various pixel sizes.

For Pléiades and SPOT 6/7, each dataset contains a bundle that consists of the individual spectral bands with coarser resolution (2 m for Pléiades and 6 m for SPOT 6/7) and the panchromatic band with the higher resolution (0.5 m for Pléiades and 1.5 m for SPOT 6/7).

Pan-sharpening is a remote sensing algorithm that uses the higher-resolution panchromatic image to fuse with the lower-resolution multiband image. This outputs a multiband image with the spatial resolution of the panchromatic image (from 2 to 0.5 m for Pléiades and from 6 to 1.5 m for SPOT 6/7).

For more information: How to Pan-sharpen Images.

My image does not look very good, what could be the problem?

UP42 distributes various geospatial data sources and the quality of the geospatial datasets (satellite, aerial and balloon images) is the responsibility of the upstream data providers.

Generally, images captured by spaceborne platforms or aircraft sensors are prone to various types of noise. For instance, noise may be added to satellite images due to atmospheric noise (e.g. aerosols, clouds) or sensor noise (e.g. angle at which the satellite views the ground at any given time). The image generation process can also add noise to the data, because these datasets have to be compressed to reduce their requirements for archiving and data transmission. Another example is salt and pepper noise, which is generated from errors in data transmission and it can affect the quality of the satellite images.

There is no exact method to correct image artifacts, but we recommend using the standard pre-processing methods (atmospheric, radiometric and geometric corrections) and the traditional digital image processing algorithms. There are several methods which can help clean the images from noise, but you should be familiar with the basic concepts. For example, image filtering can enhance the image properties and remove noise. The following filters are the most widely used in digital image processing:

a. Linear spatial filters (average, disk, gaussian, laplacian, log, motion, Prewitt, Sobel, unsharp).

b. Nonlinear filtering (median filters).

c. Fourier Transform.

Why are my Pléiades/SPOT 6/7 images rotated 90° counterclockwise?

This issue is expected if you are rendering the JPEG 2000 image file (.JP2) in a GIS software. We recommend opening the XML file (.DIM) instead. This file can be found in the image subfolders of the product folder (conventionally named IMG_PHR*/SPOT*_MS_0XX and IMG_PHR*/SPOT*_P_0XX). For more information about the image format: DIMAP V2.
