Dem2C5PointStats.java - part of C5 Landscape (C5UTM) database

Dem2C5PointStats is a C5 DEM Tool filter that processes a dem to update the C5UTM database, using java JDBC.

Dem2C5PointStats adds data to the C5UTM db UTM_POINT_STATS table, copying and processing data from a dem file directly for performance.

The purpose of this filter is to preprocess into the database as much data as is possible directly from the dem files, which is faster than getting the same data back out of the database's UTM_COORD table, thus helping to build the UTM_POINT_STATS table in more reasonable time.

Once run over a dem, this filter will set the DEM_METADATA.point_stats attribute to level 1, or "partially processed". Level one indicates that the dem's complete 1K grid areas (the 1K grid around each point) have been processed.

This filter can be executed as a batch over all available dems via the com.c5corp.c5utm.util.BuildPointStatsFromFiles class (main method). The com.c5corp.c5utm.util.BuildPointStatsFromDb utility should be used to process the the overlaping areas shared between dems. (1K areas with points in adjacent dems). This filter does not interpolate 10 meter data to 30 meter data, thus those dems originally in 10 meter format must be fully processed with Build1KGridFromDb.

The com.c5corp.c5utm.util.Build1KGridStats utility will execute these utilities wisely, using the DEM_METADATA.point_stats as a guide.

Refer to sql directory for info on the data model.
