In addition to searching for archived imagery, you can order new imagery for an Area of Interest
From the EarthCache tab in ArcGIS Pro, click on "Order Imagery". The "Order EarthCache Imagery" pane will open to the left of the active Map window.
Before ordering new imagery and drawing your own AOI, it is highly recommended that you save and close out any editing sessions you are currently performing on vector data, as this tool will automatically save any open edit sessions
To select a polygon layer from your Table of Contents as your input Area of Interest (AOI), click the dropdown under "Select AOI Layer". This dropdown will be automatically updated with any layer you add or remove from the Table of Contents.
If you want to create a new Area of Interest that's not in Table of Contents, you can draw one yourself on the map, by clicking the Pencil icon next to "Select AOI Layer"
This will open Draw tools at the bottom of your active Map window
Click on the Map to draw your Area of Interest.
Once complete, double click on the map to finish drawing. The layer will be automatically added to the dropdown as "EarthCache User AOI"
Optionally, you can give your pipeline a name by entering text in the Pipeline Name field. This will make it easier to identify and recognize from your Order Dashboard.
Choose a start and end date for the pipeline you're requesting. The end date can be a future date.
- The search range will be the entirety of the date range. The maximum is 999 days.
- This breaks the range into multiple orders based on the days of collection. This is common for change detection and monitoring purposes. Here are some examples.
- Multiple - 30 days, June 1 - September 30
- 4 captures - 30 days, 30 days, 30 days, 2 days
- June 1 - June 30, July 1 - July 30, July 31 - August 29, August 30 - September 29th, September 29th - September 30th. Since 2 of those months are 31 days, there is a short interval added to the end.
- Multiple - 31 days, June 1 - September 30
- 3 captures - (31 days, 31 days, 30 days)
- June 1 - July 1, July 2 - August 1, August 2 - September 3, September 3 - September 30
It is recommended to turn mosaicking on for tasking. Mosaicking will stitch together any products which provide partial coverage of the AOI. If this is turned off and 2 images are collected which each cover 50% (i.e. do not reach your coverage setting) no imagery will be returned.
Tasking enables the end-user to request that a satellite collect imagery of the AOI during a certain time interval. Tasking data has a higher chance of data being collected, therefore is offered at a premium rate and includes minimum order sizes. This means you will be charged as if your area of interest was 25 km² (or larger if your area of interest is larger than 25 km²). Collection is not guaranteed but probable. Furthermore, tasking is enabled only for High and Very High Resolutions.
This coverage value is for usable pixels. This means that it considers total overlap, as well as cloud percentage. If it were 5% clouds and 90% overlap, a 90% coverage setting would return no results. This should not be set 90% or higher as it greatly reduces your chances of getting imagery. You will be charged for the entire area of interest.
This value is default-set to 80%.
You can also expand the "Add Tags" section to add text labels and values to this order. Doing this can make searching for results in the Order dashboard easier.
Information about pricing (given in USD):
When Tasking is allowed, the following prices apply.
- High Resolution: $12/km²
- Very High Resolution: $30/km²
Furthermore, if you have multiple intervals set, this will reflect in the price. If there are 3 features being submitted, each one is $500 dollars, then the order will show 3 pipelines and $1500. If in addition there are 2 intervals, the order total will show 3 pipelines and $4500.
When ready to submit your order, click "Submit". You will see the following prompt. Click "Yes" to continue.
The EarthCache Order Dashboard will open to the left of the Active Map, where you can see the pipeline you just created.
