• A key can be displayed for NDVI and RENDVI by clicking on the scalebar in the bottom left corner of the map.

2.4.1 Full screen mode

• To enter full screen mode, click on the icon in the top righthand corner of the map.

• To exit full screen mode either click the X in the top right, or press escape on your keyboard.

2.5 Downloading imagery

• To analyse imagery fully it must be exported to a GIS application such as the powerful and free QGIS – which can be downloaded here. We will be posting tutorials on how to use QGIS with our satellite and UAV imagery in our blog.

• To download a satellite image from a Project/Farm go to: My Data > Project > Satellite Imagery.

• Locate the image you want to download from the list and click on the download arrow icon. This will download a ZIP file which contains 4 TIFF image files.

2.6 Renaming an image

• By default, each satellite image is named after the date it was captured, followed by the name of your Farm/Project. To change this name, click on the pencil icon after the image name, type the new name, and press enter to save.

2.7 Deleting an image

• Although we do our best to filter out any high cloud cover images before they get to your account, occasionally, a satellite image will be unusable due to high cloud cover. In this case you may want to delete this image from your account.

• To delete an image, click on the trashcan icon, and confirm the image should be deleted.

2.8 Imagery details

• The satellite imagery you receive is a combination of multispectral imagery from the European Space Agency's Sentinel-2A and Sentinel-2B earth observation satellites. We provide fully atmospherically corrected Level 2A imagery for 100 KM2 area of your choosing. We provide the 8 most useful bands for vegetation monitoring, these are listed in the table below.

 Table 1. Sentinel-2 bands available through the Buzzard Data Hub.

Table 1. Sentinel-2 bands available through the Buzzard Data Hub.

• Atmospheric correction is completed using the Sen2Cor processor with elevation corrections using the SRTM 90m digital elevation model.

• The image named e.g. 20171106T112229_ALL.TIF in your downloaded zip file will contain all the bands listed above; the bands within this image are in the same order as the table above. The date and time the image was captured is listed at the start of the file name in the format: YYYYMMDD"T"HHMMSS.

• The downloaded zip file will also contain an image named e.g. 20171106T112229_RGB.TIF; this file contains Sentinel-2 bands B02, B03, B04. When opened in a GIS application such as QGIS, this image will appear as a true colour image.

• The zip file also contains the pre-calculated vegetation indices; RENDVI and NDVI. NDVI is calculated using bands B04 and B08. RENDVI is a more accurate chlorophyll estimating vegetation index than NDVI but is calculated using 20m spatial resolution bands. RENVI is calculated using bands B05 and B06.

• It is recommended that these images are viewed using geographic information system software, such as QGIS.

2.9 Missing Imagery

• If Sentinel-2A/B has passed over your selected location and you have not recieved imagery it could be due to:

     - A greater than 95% cloud-cover on your imagery. Images with this level of cloud-cover are considered unusable and are removed.

     - The 100KM2 location you have selected is only partially within the captured Sentinel-2 image. Only images with over 98% coverage are published to your account.

     - It's less than 24 hours since you created or changed the position of the location you would like to receive satellite imagery for.

3. UAV Image Processing

3.1 General

• To process imagery from your Buzzard multispectral camera into highly precise, georeferenced maps you need to upload your imagery to the Buzzard Data Hub for processing. Alternatively, you can process the imagery yourself using either Agisoft Photoscan or Pix4D Mapper. Imagery processed externally cannot be added to the Buzzard Data Hub map viewer.

• Processing credits are required to upload imagery from your Buzzard multispectral camera for processing. Credits can be purchased individually, or you can subscribe to a plan which includes a monthly quota of processing credits.

• One processing credit allows upto 750 images to be processed.

• A payment card must be added to your account to buy processing credits or sign up to a paid subscription plan.

3.2 Uploading imagery

• To upload imagery from your Buzzard multispectral camera follow the steps below:

          • Step 1: Please transfer the imagery from the camera onto your computer.

          • Step 2: Select the Upload Imagery tile from the home page.

          • Step 3: From the upload imagery page give the upload a name. 

          • Step 4: Select which Project/Farm these belong to from the dropdown list. If you have not yet created a Farm/Project for this upload, click on the green plus icon ⊕ to create a new one.

          • Step 5: Next, select the Study Site/Field that this upload belongs to. If you have not yet created a Study Site/Field for this upload, click on the green plus icon ⊕ to create a new one.

          • Step 6: Drag and drop the images you wish to process into the upload box. Alternatively, you can click the upload box and select the files from a location on your computer.

          • Step 7: Click the upload button and wait for the uploads to complete. This may take a while to complete depending on your connection speed.

          • Step 8: Your procressed imagery will be available within 48 hours. The imagery will appear in the Project/Farm and Study Site/Field you selected.

3.3 Viewing processed imagery

• Processed imagery can be viewed by viewing navigating to: My Data > Your Farm/Project > Your Field / Study Site

• Find the processed image you want to view on the map and click on the ADD button. When an image has been successfully added to the map the ADD button will change to REMOVE, click the button again to remove the image from the map.

• Once you have selected ADD on the images you want to view, click the MAP VIEWER button at the top of the page. This will open the map viewer.

• If you have added multiple images to the map viewer, all the images will appear in the sidebar on the left. The image that is first on the list displays on top. The order of the images can be adjusted by dragging the images by its name. Processed UAV imagery can be placed on top of satellite imagery by placing both on the map at the same time.

• Processed multispectral camera images can be controlled in the same way as satellite imagery. Please see Section 2 of this guide for more information.

3.4 Downloading processed imagery

• To analyse imagery fully it should be exported to a GIS application such as the powerful and free QGIS – which can be downloaded here. We will be posting tutorials on how to use QGIS with our satellite and UAV imagery in our blog.

• To download a processed image: My Data > Your Farm/Project > Your Field/Study Site.

• Locate the image you want to download from the list and click on the download arrow icon.
