PremiseThese changes were requested by NSIDC and LPDAAC to reduce the number of failed requests that enter the system. On the front page of Earthdata Search Client, if an end user searches for granules using a bounding rectangle, the coordinates of that rectangle will be pre-populated into any ECHO form loaded in that user's same session. Applying a read-only attribute to the spatial subset fields prevents the user from modifying the pre-populated values, thus guaranteeing that a valid spatial subset will be submitted with the request. For any collection to which the following fixes have been applied, the resulting behavior will force users to specify a spatial subset by searching for granules using the bounding search rectangle; they will not be able to edit the bounding box in the form itself. |
