资源简介：
A polygon feature class of the US National Grid boundaries within Miami-Dade County. This layer represents a 100 by 100 meter United States National Grid (USNG) for Miami-Dade County. The USNG is an alpha-numeric reference system based on the UTM coordinate system and is similar to the Military Grid Reference System. Use of the USNG ensures a uniform grid mapping and positional reporting system for search and rescue, emergency planning, response, and recovery.
