I'm trying to develop a flood simulator, so looking for more precision than google maps elevation API which presents a resolution of 152.07 in my region, i'm testing srtm3. I still couldn't find diferences from the results obtained between both services, only that srtm json elevation value is just an integer.
Which service would be more suitable for me?

srtm1 or aster should be better than srtm3.
srtm1 has a sample area of around 30m x 30m whereas srtm1 has 90m x90m. All these global datasets have metre or more resolution and return an integer.
