1. ArcGIS Pro - facing problem in importing the data from SNAP to arcgis pro layer is not visible.

2. Arcmap and QGIS - data was imported from SNAP but not georeferenced after importing data in these Softwares.

Hi :

To successfully export data from ESA's Sentinel Application Platform (SNAP) and import it into ArcGIS Pro, ArcMap, and QGIS, it's essential to ensure that the data is properly processed, georeferenced, and saved in a compatible format. Below is a step-by-step guide to address the issues mentioned:

1. Exporting Data from SNAP

Step-by-Step Export from SNAP:

Open SNAP: Launch the SNAP software and load the desired product (e.g., Sentinel-1, Sentinel-2).

Apply Processing Steps: Perform necessary preprocessing steps like calibration, terrain correction, and any other required processing.

Subset the Area (Optional): If you only need a specific area, create a subset by selecting Raster > Subset and defining the area of interest.

Export Data:Go to File > Export > GeoTIFF/BIGTIFF. In the export dialog, configure the parameters:Ensure to select the appropriate bands or indices. Choose the output directory and file name. Ensure to check the box for including georeferencing information. Click OK to export the data.

2. Importing Data into ArcGIS Pro

Step-by-Step Import into ArcGIS Pro:

Open ArcGIS Pro: Launch ArcGIS Pro and open or create a new project.

Add Data:Go to the Map tab and click Add Data. Navigate to the exported GeoTIFF file from SNAP and select it.

Check Layer Visibility:If the layer is not visible, ensure that it has been added to the map and is checked in the Contents pane. Adjust the symbology if necessary by right-clicking the layer and selecting Symbology. Verify the coordinate system of the map and the layer match. Right-click the layer, go to Properties, and check the Source tab for the spatial reference information.

3. Importing Data into ArcMap and QGIS

Step-by-Step Import into ArcMap:

Open ArcMap: Launch ArcMap and open a new or existing map document.

Add Data:Click on the Add Data button. Navigate to the exported GeoTIFF file and add it to the map.

Georeferencing:If the data is not georeferenced, go to Georeferencing > Fit To Display. Use the Georeferencing toolbar to adjust the image to fit the correct geographic location. Add control points if necessary to ensure proper alignment.

Step-by-Step Import into QGIS:

Open QGIS: Launch QGIS and open a new or existing project.

Add Data:Click on Layer > Add Layer > Add Raster Layer. Navigate to the exported GeoTIFF file and add it to the map.

Check Georeferencing:If the data is not georeferenced, use the Georeferencer plugin. Open the Georeferencer plugin, load the raster, and add control points to georeference the image. Save the georeferenced raster and add it back to the map.

Here are troubleshooting Tips you may need :

Layer Not Visible in ArcGIS Pro:Ensure the coordinate system of the layer matches the map. Adjust the display range settings of the layer. Check for any display filters that might be hiding the layer.
Georeferencing Issues in ArcMap and QGIS:Verify the exported GeoTIFF file contains proper georeferencing information. If the data is still not georeferenced, consider re-processing the data in SNAP with terrain correction and export it again.

Please recommend my reply if you find it useful .Thanks
