There is no hurry, but I found this in the code, and it didn't seem very logical.

Perhaps we can just use LLONG_MIN from limits.h, rather than hardcoding it? #include <stdio.h> #include <limits.h> int main() { // Output the maximum value of an unsigned long long printf("The maximum value of unsigned long long is: %llu\n", ULLONG_MAX); return 0; } -9223372036854775808

I don't think this actually breaks something: if I understand it correctly, this nodata value is only used when creating a new grid from scratch. Files will have stored nodata values. I'm double checking the value.

Use more logical nodata values for long/ulong
