Convert a GOF file to a LAS statistics file.
Allows the user to convert a polygon graphic overlay file (GOF) to a LAS statistics file. If the statistics file already exists, it is updated; otherwise, a new statistics file is created. If the class and site already exist but do not have polygon data, the polygon data are inserted for that site; otherwise, the polygon data are added for new sites.The polygon data are compatible between the two file formats; however, the GOF attributes and the statistics class and site names are not. The differences are listed in User Note 2.
- INGOF
- Input graphics overlay file. The input GOF file is required to be polygon data. Other types of GOF data (point, line, and annotation) do not correspond to any of the data types in a LAS statistics file.
- OUTSTAT
- Output statistics file. If the statistics file already exists, it is updated; otherwise, a new statistics file is created.
- CLASSATR("CLASS")
- Class attribute. Specifies which GOF attribute name is to be used for the statistics class.
- SITEATR("SITE")
- Site attribute. Specifies which GOF attribute name is to be used for the statistics site.
- CLASSNAM(--)
- Class name. A list of GOF attribute values defining class names for the output statistics file. Records from the GOF file are copied only if the attribute value for the class matches the list defined by CLASSNAM. The default implies all attribute values for the class match.
- SITENAM(--)
- Site name. A list of GOF attribute values defining site names for the output statistics file. Records from the GOF file are copied only if the attribute value for the site matches the list defined by SITENAM. The default implies all attribute values for the site match.
All polygons in GOF file PHOENIX are copied to the LAS statistics file PHOENIX. GOF attribute name LANDUSE is used for the statistics class, and GOF attribute name WATER is used for the statistics site.
Selected polygons in GOF file PHOENIX are copied to the LAS statistics file PHOENIX. GOF attribute name LANDUSE is used for the statistics class, and GOF attribute name WATER is used for the statistics site. Only those polygons that have the specified attribute values are copied; i.e., attribute value of LANDUSE is required to be INDUSTRIAL or AGR and attribute value of WATER is required to be RIVER or LAKE.
GOF2STAT is a procedure PDF which invokes GOF2TAB to copy the GOF file to a labeled table (LT) file, and TAB2STAT to copy the LT file to a LAS statistics file. The LT files are deleted at completion. See the documentation for GOF2TAB and TAB2STAT for more information.
