Texas Address and Base Layers Story Map

This resource links to the Texas Address and Base Layers Story Map (Esri ArcGIS Online web app) [1] that provides a graphical overview and set of interactive maps to download Texas statewide address points, as well as contextual map layers including roads, rail, bridges, rivers, dams, low water crossings, stream gauges, and others. The addresses were compiled over the period from June 2016 to December 2017 by the Center for Water and the Environment (CWE) at the University of Texas at Austin, with guidance and funding from the Texas Division of Emergency Management (TDEM). These addresses are used by TDEM to help anticipate potential impacts of serious weather and flooding events statewide.

For detailed compilation notes, see [2]. Contextual map layers will be found at [3] and [4].

November 2023 update: in 2019, TNRIS took over maintenance of the Texas Address Database, which is now updated annually as part of the StratMap program [5]. Also, TNRIS changed its name this year to the Texas Geographic Information Office (TxGIO). The StratMap and DataHub download sites still use the tnris.org domain but that may change .

更详细的编制说明请参阅 [2]。背景地图层可从 [3] 和 [4] 获取。

2023年11月更新：2019年，德克萨斯州自然资源信息中心（TNRIS）接管了德克萨斯州地址数据库的维护工作，现在该数据库作为 StratMap 项目 [5] 的一部分每年更新一次。此外，TNRIS 在本年度更名为德克萨斯州地理信息办公室（TxGIO）。StratMap 和 DataHub 下载网站仍使用 tnris.org 域名，但可能有所变更。
