How to retrieve pixel coordinates from sentinel lat/lon arrays for a given location?

I have a Sentinel-3 satellite scene and i need the exact pixel coordinates for some lat/lon coordinates for further calculations. The sentinel scene comes with one array with lat-values and one with lon-values for every pixel. I tried the ingeoquad-function but it does not return the exact pixel representing my geo-location in all cases. Is there any better solution to this?

Read about scatteredInterpolant if you want to do by intpolation......Read about knnsearch if you want a neasrest value.

I'm still not sure if this is what i need to get my pixel.
What i basically need to do is to determine the pixel clostest to the position of for example LAT = 49.1354, LON = -12.5574 from "mapmtx" example-dataset and the corresponding arrays lt1 and lg1.
