资源说明：SEG-Y Reading in C#
# SEG-Y Reading Library in C# #
SEG-Y is a file format for seismic image data. It is also known as SEGY or SGY.
Issues and sample data welcome.
### Example
```C#
using System;
using Unplugged.Segy;
```
```C#
var reader = new SegyReader();
ISegyFile line = reader.Read(@"RMOTC Seismic data set\2D_Seismic\NormalizedMigrated_segy\lineA.sgy");
ITrace trace = line.Traces[0];
double mean = 0;
double max = double.MinValue;
double min = double.MaxValue;
foreach (var sampleValue in trace.Values)
{
mean += sampleValue / trace.Values.Count;
if (sampleValue < min) min = sampleValue;
if (sampleValue > max) max = sampleValue;
}
Console.WriteLine(min);
Console.WriteLine(max);
Console.WriteLine(mean);
```
### Supported Sample Formats
- IBM Floating Point 4 (Big Endian)
- IEEE Floating Point 4 (Little Endian)
- Two's Complement Integer 4 (Big and Little Endian)
- Two's Complement Integer 2 (Big and Little Endian)
- Two's Complement Integer 1
### Current Known Limitations
- Assumed to be built on Little Endian architecture
- Sample Format not supported: Fixed Point With Gain 4
- Extended Text Headers are not supported
- Writing SEGY files is not supported
If you have example files of unsupported formats or feature requests, they would be appreciated! Please, send to
