"While the datasets we will be comparing in this notebook are quite similar, they contain important differences related to how they were processed. The product description pages for both datasets contain important information for understanding how they are generated.\n",
"\n",
"### Source data\n",
"One important difference is the source data used to generate the RTC images. ASF uses the Single Look Complex ([SLC](https://sentinels.copernicus.eu/web/sentinel/technical-guides/sentinel-1-sar/products-algorithms/level-1-algorithms/single-look-complex)) images that contains both amplitude and phase information for each pixel, is in radar coordinates and has not yet been multi-looked (double check). The Microsoft Planetary Computer RTC imagery is generate from ground range detected images (GRD). [GRD](https://sentinels.copernicus.eu/web/sentinel/technical-guides/sentinel-1-sar/products-algorithms/level-1-algorithms/ground-range-detected) data has been detected, multi-looked and projected to ground range.\n",

"### DEM\n",
"A digital elevation model (DEM) is an important input parameter for RTC processing. ASF RTC processing uses the Copernicus DEM with 30 m resolution. Planetary Computer uses higher resolution DEMs. One effect of the use of different DEMs during RTC processing is the different spatial resolutions of the RTC products: **Planetary Computer RTC imagery has a spatial resolution of 10 meters while ASF RTC imagery has a spatial resolution of 30 meters.**"
