CDFW Facilities [ds3076]

This is a point layer representing California Department of Fish and Wildlife (CDFW - formerly California Department of Fish and Game - DFG) facilities. In 1995, under the request of John Ellison, the original coverage was created by Teale Data Center using address matching of the DFG phonebook dataset. In March of 1996, Isaac Oshima and Paul Veisze used a SPOT Imagery confirmation process applied to those facilities for which Teale could not find an address match. The update occurred using SPOT View imagery sent to the various DFG facilities. The key personnel were requested to 'ink-in' the actual physical location(s) considered to be the HQ for that particular facility. The maps were then sent back and the correct point was represented in the GIS by a point. In 1999, under Paul Veisze, GIS staff were allocated the task of calling each facility within a region and checking whether the information on file was correct. The dataset was subsequently updated. Currently, the data is updated through receiving a database from FASB/Tami Garfio ("telephone and facility List"). Point locations are verified by contacting appropriate CDFW staff or cross referencing with google and yahoo maps, gis roads layer, and imagery.本数据集为点图层，用于展示加利福尼亚州鱼类与野生动物局（California Department of Fish and Wildlife，简称CDFW，前身为加利福尼亚州鱼类与狩猎局California Department of Fish and Game，简称DFG）的各类设施。1995年，应约翰·埃利森（John Ellison）的要求，蒂尔数据中心（Teale Data Center）通过对DFG电话簿数据集开展地址匹配操作，创建了初始数据集覆盖范围。1996年3月，艾萨克·大岛（Isaac Oshima）与保罗·韦伊斯（Paul Veisze）针对蒂尔数据中心未能匹配到地址的设施，采用SPOT影像（SPOT Imagery）确认流程进行补充核查。本次更新依托SPOT View影像完成，工作人员向各DFG设施发送该影像，要求核心人员手工标注被认定为该设施总部的实际物理位置，随后收回标注完成的地图，并在地理信息系统（Geographic Information System，以下简称GIS）中以点要素形式标记出准确位置。1999年，在保罗·韦伊斯的牵头下，GIS工作人员负责致电辖区内各设施，核实存档信息的准确性，随后对数据集进行了更新。目前，该数据集通过接收FASB/塔米·加菲奥（Tami Garfio）提供的“电话与设施清单”数据库完成更新。点位坐标需通过联系相关CDFW工作人员，或通过谷歌地图、雅虎地图、GIS道路图层及影像资料交叉验证，以确保位置信息准确无误。
