I have some Tanzania drone imagery data in a local geographic projection EPSG:32737 that uses the unit of meters. Then I have other vector data that is in EPSG:4326 which is denominated in degrees. In order to map the vector data on the imagery, I converted the imagery over to 4326. Since I believe 4326 is the most popular projection, I figured having all data in that projection would make things easier and avoid inadvertent projection errors.
The problem is that I want to resample the imagery to a lower resolution. In the original projection the units were meters but in 4326 the units are degrees. So my question is, is there a simple rule of thumb to convert between degrees and meters--given some local projection? Like what is the algorithm to compute this. Note the total study area is about 2 miles x 2 miles in size, since the resolution is so high.
Note, I understand that a degree corresponds to a different number of meters, depending on where on earth the imagery or geography is captured. So that is fine. But given that I am using EPSG:32737 versus EPSG:4326, I want to know
A more precise definition of the problem is this. The original imagery is 6cm resolution, and that is in EPSG:32737. After converting the image to EPSG:4326, I want to resample the image to 1 meter resolution. So how many degrees correspond to 1 meter distance in Tanzania? Is there a simple equation to do this, or is there some package or website I can use?
In terms of tools, I was using
GDAL in python. I would like to do this through code instead of through a tool like
