US HIST FIRE PERIM 2006 DD83

The Geospatial Multi-Agency Coordination Group, or GeoMAC, is an internet-based mapping tool originally designed for fire managers to access online maps of current fire locations and perimeters in the US. Perimeters are submitted to GeoMAC by field offices. The GeoMAC team attributes the perimeters using various sources, and then posts them on the GeoMAC website and to an HTTP site for downloading. This file contains all the latest fire perimeters that were processed by the GeoMAC team between 2000 and 2018. The projection is geographic and the datum is NAD83.

地理空间多机构协调小组（Geospatial Multi-Agency Coordination Group，简称GeoMAC）是一款基于互联网的制图工具，最初专为火灾管理人员开发，用于获取美国境内当前火灾点位与过火边界的在线地图。野外办公机构会向GeoMAC提交过火边界数据。GeoMAC团队通过多源数据为这些过火边界添加属性信息，随后将其发布至GeoMAC官方网站及可供下载的HTTP站点。本数据集包含2000年至2018年间由GeoMAC团队处理的全部最新火灾过火边界数据。该数据集采用地理投影，基准面为NAD83。
