I am working in a Geographic coordinate system in ArcGIS, and I need to create TIFFs by exporting rasters. THese .TIF file must have a resolution (cell size, or GSD) of 1 m.
Is it possible to set any parameter in the Export Raster Data window to achieve this goal?
If you want an exact value, this is simply not possible. Indeed, the size of a degree varies with the location, so you can't tell exactly the size of your pixel in meter based on a grid in degree. If you convert to a projected coordinate sytem, this grid will be distorted and you will need some kind of resampling.
For a quick estimate, you can consider that 1 degree of latitude = 111.3 km and one degree of longitude = 111.3 km* cos(latitude). See here for more details
The dialog for Data::Export Data contains the format:
It's been that way since at least version 9. This screen shot is from v10.1 and 10.2 is very similar (just a different drop down style).
Best Answer
1) Use the resample tool and find the size in meters at your particular latitude.
This site will do that conversion for you.
Then you have it in meters.
2) More likely a better approach would be to convert you data (reproject) into a projected system that uses meters. A good example for the US would be USGS Albers Equal Area but you need to find one that works well for your region.
