CFVA — perimeters areas covered by fire — 2007

This information layer delimits the areas affected by the fire. Each fire is bounded by a single range. Only fires that have affected areas of more than 1000 square meters are reported.. The surveys are made directly in the countryside by forest personnel, with GPS handheld tool. They are subsequently checked and reworked in the central offices with GIS software.本信息图层划定了受火灾影响的区域范围。每起火灾仅由单一范围划定边界。仅上报过火面积超过1000平方米的火灾灾情。此项调查由林业人员借助手持GPS设备在野外现场直接开展，后续将通过地理信息系统（GIS）软件在中央办公场所对调查数据进行核查与修正完善。
