Hello,
I am assuming your software is capable of creating a mask, but I do not know what you have or if I am familiar with your software.
Thanks.

Hi Duanyang,
We wanted to make sure all was well. Were you able to download the previously missing tiles?
Thanks,
Brett

Hi @akasom We are having our developers looking into this, not sure if there is a way to filter this out at this time. As soon as we hear back I will let you know.
Thanks,

Re: ECOSTRESS Highest resolution
Good Morning, The User Guide states 90 x 90, and I can't comment on that because I don't know their rationale or formula for arriving at that value, also, I don't know your formula for arriving at 45, but that does make it seem reasonable for the developers to arrive at ~70 meters, along with the fa...

Re: ECOSTRESS Highest resolution
Hello, In any given Ecostress swath directly from the sensor on board the ISS the pixel size ranges from ~38 meters x 69 meters to ~90 meters x 90 meters along the edge of the swath. So pixel size varies greatly as it does with most all satellite data. The derived products need to be uniform so ~70 ...

Re: Delay in Availability of MODIS Products (MOD09A1 & MYD09A1)
Hello, Sorry for the delay with the data processing. There are many factors that can affect data processing. It can be sensor and/or satellite related such as maneuvers and satellite issues. There will probably be more of this as Terra and Aqua age. Also, there can be issues at MODAPS as far as infr...

Re: Harmonization or fusion of Landsat and Sentinel-2 data for geomorphological analysis of Italian rivers
Hi Rosita, I ran this by some science folks and we really don't think there is a good answer on how this can be done satisfactorily. The advantages of our HLS products are they take Landsat 8 and 9 and Sentinel 2 and use the same processing algorithm and are able to get coverage every 2-3 days at 30...

Re: MOD09GA in HDF Preprocessing
Hello, That is up to what you would like, it does not need preprocessing, it is atmospherically corrected. However, it is available in our AppEEARS tool which can perform many tasks such as subsetting by area and band, it can also reproject and reformat if you would like: https://appeears.earthdatac...
