Recently I have provided two Twitter Accounts Poland Sentinel and Gdansk Bay Sentinel which are posting satellite images from the ESA Sentinel 2A satellite. FME Server once again helped me in the automation of these interesting projects.
Brief of the Process
Workspaces are of course built in FME Desktop 2022. Firstly I have created Gdansk Bay Sentinel because it’s easier to develop downloading only one region – the process is checking the same coordinates every day and if there is a published new image that day… it is shared to a Twitter account.
Poland Sentinel workspace is more complicated as its checks two locations per day. I have also gathered a list of 1164 points of interest with coordinates and my intention is to extend that. Plan is to tweet two locations per day, so that would give us original satellite images for 582 days. Currently, most points from the list are Cities (more than 900) and Landscape Parks (translated from Park Krajobrazowy). Below example section of the table which I use to store the data, coordinates are in WGS84 (EPSG: 4326) coordinate system:
|1||Park Krajobrazowy Pogórza Przemyskiego||49.72757||22.52355||Park Krajobrazowy|
|2||Magurski Park Narodowy||49.51445||21.45801||Park Narodowy|
|4||Zamek Pieskowa Skała||50.24409||19.78014||Zamek|
For Gdansk Bay Sentinel I have set a simple Schedule on FME Server. But for the Poland Sentinel profile, I have used Automations option because it has a nice Retry feature in case of a failure. That will almost guarantee that there will be a tweet every day.
Technology gives me possibility to easily integrate it with other social media, but for now let’s keep it only on Tweeter and check how it will be liked.
