OpenStreetMap Landuse Areas for North America
收藏资源简介:
This feature layer provides access to OpenStreetMap (OSM) landuse areas data for North America, which is updated every 15 minutes with the latest edits. This hosted feature layer view is referencing a hosted feature layer of OSM polygon (closed way) data in ArcGIS Online that is updated with minutely diffs from the OSM planet file. This feature layer view includes landuse features defined as a query against the hosted feature layer (i.e. landuse is not blank). In OSM, landuse describes the primary use of land by humans. These features are identified with a landuse tag. There are thousands of different tag values for landuse used in the OSM database. In this feature layer, unique symbols are used for several of the most popular landuse types, while lesser used types are grouped in an "other" category. Zoom in to large scales (e.g. City level or 1:80k scale) to see the landuse area features display. You can click on a feature to get the name of the landuse area (if available). The name of the landuse area will display by default at large scales (e.g. Street level of 1:5k scale). Labels can be turned off in your map if you prefer. Create New Layer If you would like to create a more focused version of this landuse areas layer displaying just one or two landuse types, you can do that easily! Just add the layer to a map, copy the layer in the content window, add a filter to the new layer (e.g. landuse is commercial), rename the layer as appropriate, and save layer. You can also change the layer symbols or popup if you like. Esri may publish a few such layers (e.g. residential, forest) that are ready to use, but not for every type of landuse area. Important Note: if you do create a new layer, it should be provided under the same Terms of Use and include the same Credits as this layer. You can copy and paste the Terms of Use and Credits info below in the new Item page as needed.
本要素图层可提供北美地区开放街道地图(OpenStreetMap,简称OSM)的土地利用区域数据,每15分钟同步一次最新编辑内容。本托管要素图层视图引用了ArcGIS Online中的OSM多边形(闭合道路,closed way)数据托管要素图层,该图层通过OSM全球数据文件的分钟级增量差异数据完成更新。本要素图层视图包含通过对托管要素图层执行筛选查询(即土地利用字段非空)得到的土地利用要素。在OSM中,土地利用(landuse)字段用于描述人类对土地的主要使用方式,此类要素通过landuse标签进行标识。OSM数据库中存在数千种不同的土地利用标签取值。本要素图层为几种最常用的土地利用类型配置了专属符号,使用频率较低的类型则被归入「其他」类别。放大至大比例尺(例如城市级或1:80000比例尺)时,方可显示土地利用区域要素。点击任意要素即可查看其所属土地利用区域的名称(如存在该信息)。在街道级1:5000比例尺等大比例尺下,土地利用区域名称将默认显示;若您偏好无标注的地图,可自行关闭标签显示。创建新图层 若您希望打造更聚焦的土地利用区域图层,仅展示一至两种土地利用类型,操作十分简便:只需将本图层添加至地图,在内容窗口中复制该图层,为新图层添加筛选条件(例如土地利用字段为商业用地),按需重命名图层后保存即可。您还可根据需求调整图层符号或要素弹窗内容。Esri已发布部分此类预可用图层(例如居住用地、林地图层),但并未覆盖所有土地利用类型。重要提示:若您自行创建新图层,新图层需遵循与本图层一致的使用条款,并保留相同的署名声明。如需操作,您可在新图层的条目页面中复制粘贴下方的使用条款与署名声明信息。
