Historical Canadian Railroads

Historical Canadian railway lines, places, and transactions in GIS formats. HR_rails_NEW contains historical railway lines with dates of activity. Modified from a proprietary dataset produced by ESRI Canada. hr_places_all was also created from an ESRI base layer. Points were repositioned using the ESRI base as reference, and new points were also added from the railway atlas.This set of place names was used as an intermediary layer when making the final dataset of railway lines. The places named are points where railway construction dates change.本数据集包含地理信息系统（GIS）格式的加拿大历史铁路线路、地名点位及相关交易记录。其中HR_rails_NEW包含带有运营活动日期的历史铁路线路数据，其源自ESRI加拿大（ESRI Canada）制作的专有数据集并经修改。hr_places_all同样基于ESRI底图图层创建，制作过程中以该ESRI底图为参照对原有点位进行了重定位，并从铁路地图集中补充了新的点位。该地名数据集在制作最终铁路线路数据集时被用作中间图层，其中标注的点位均为铁路建设日期发生变更的位置。
