AndreaBozzo/ceres-open-data-index huggingface dataset:
Cities And Urban Service Districts

This feature class contains polygon geometry for all recognized communities within Tulare County, including incorporated cities and multiple types of minor community districts. The dataset is derived from authoritative district boundary inventories maintained by TCiCT/GIS and combines the A1_MajorCommunities and A2_MinorCommunities layers into a single, structured feature class. This dataset supports internal operations, public mapping tools, inter‑agency planning, and spatial analysis requiring accurate district and community boundaries. It is intended to serve as a foundation for additional derived feature layers through definition queries or filtered web services.
Mosquito Abatement Districts

This GIS data layer defines Mosquito Abatement Districts, outlining their geographic boundaries and district names. These districts are established to monitor and control mosquito populations, reducing the spread of mosquito-borne diseases and enhancing public health. The dataset supports environmental management, pest control planning, and local governance by providing a spatial reference for jurisdictional areas. Users can leverage this layer to assess treatment zones, coordinate abatement strategies, and enhance community health efforts.

Site Structure Address Points

The Site/Structure Address Point layer represents individual addressable locations, including residential, commercial, industrial, and public structures. Each point corresponds to a physical site or structure and includes standardized attributes such as street name, house number, city, ZIP code, and jurisdictional information. This dataset is maintained in compliance with the NENA-STA-006.2a-2022 standard, supporting Next Generation 9-1-1 (NG9-1-1) services. These address points are essential for accurate call routing, location validation, and emergency dispatch. The data is updated regularly to reflect new developments, address changes, and corrections. It is intended for use by public safety agencies, local governments, and the general public for planning, analysis, and emergency preparedness.
