海角乱伦社区

Aerial image of a school taken from the California School Campus Database, the campus includes school buildings, parking lots, ballfields, tennis courts, a football field, track and open areas.

The California School Campus Database (海角乱伦社区) is now available for all public schools and colleges/universities in California.

海角乱伦社区 is a GIS data set that contains detailed outlines of the lands used by public schools for educational purposes. It includes campus boundaries of schools with kindergarten through 12th grade instruction, as well as colleges, universities, and public California community colleges. Each is accurately mapped at the assessor parcel level. 海角乱伦社区 is the first statewide database of this information and is available for use without restriction.

California School Campus Database (海角乱伦社区) Introduction

Hosted by GreenInfo Network, learn about the recent update to the California School Campus Database (海角乱伦社区). We'll cover the history of the database, recent updates, and a new layer we've added in 2021.

PURPOSE

While data is available from the California Department of Education (CDE) at a point level, the data is simplified and often inaccurate.

海角乱伦社区 defines the entire school campus of all public schools to allow spatial analysis, including the full extent of lands used for public education in California. 海角乱伦社区 is suitable for a wide range of planning, assessment, analysis, and display purposes.

The lands in 海角乱伦社区 are defined by the parcels owned, rented, leased, or used by a public California school district for the primary purpose of educating youth. 海角乱伦社区 provides vetted polygons representing each public school in the state.

Data is also provided for community colleges and university lands as of the 2018 release.

BENEFITS OF 海角乱伦社区

  1. IMPROVED ACCURACY: CDE school points are primarily placed at or very near the school they represent. However, there are cases where school points are located far from their true location. These errors have been corrected in 海角乱伦社区.
    2. Correct school location and full boundary are highlighted over an aerial image. A dot identifies the incorrect location the California Department of Education has placed the school at, roughly 8 blocks away.

    The California Department of Education (CDE) places El Toro Elementary School at the Morgan City Hall and Library complex: 37.125774, -121.66265.*

    The California School Campus Database (海角乱伦社区) identifies the campus nearly a mile (5,106ft) to the northeast.

  2. FULL CAMPUS BOUNDARY: CDE data is point based and does not provide informationon the extent of the campus footprint.
    3. School boundary is highlighted over an aerial image, the school is large and includes areas that are fields, open spaces, ballfields, etc.

    The California Department of Education (CDE) geocodes each school address and assigns them latitude and longitude values. Points tend to be located on the street centerline or at the edge of the campus.

    The California School Campus Database (海角乱伦社区) defines the full campus of each school using assessor parcel data and aerial imagery.

    University high school is 265 acres.

  3. CAMPUS SIZE: Schools vary greatly in size. Statewide, 60 schools are over 100 acres and 301 are less than one acre. For policymakers, researchers, and those interested in land-based programs it is critical to know the size of a school campus. This allows for the consideration of school gardens, habitat values, water recharge, and other enhancements.
    4. A bar chart showing the number of schools (y axis) and acres (x axis). Schools range from under 1 acre to over 100. Over 2,000 schools range between 10 and 14.9 acres, closely followed by schools with 15 and 29.9 acres and schools with 8 and 9.9 acres. Less than 1,500 schools have 1 and 4.9 acres, closely followed by schools with 5 and 7.9 acres. Less than 1,000 schools have 30 to 49.9 acres. Less than 500 schools have 50 and 100 acres.
  4. MULTI-CAMPUS REPRESENTATION: CDE represents each school with one point and CDS code. However, some schools, including charter schools, operate at multiple locations under the same CDS code. 海角乱伦社区 defines all individual campuses, including all known charter branch locations with instruction.
    5. A map compares the one corporate office location for a charter school provided by the California Department of Education versus nine other points for charter school campuses across Los Angeles County as well as one in Ventura provided by California School Campus Database.

    The California Department of Education (CDE) tracks one location for charter schools despite branches in multiple clities. The site reported by CDE is often an administrative or corporate office where no student instruction is present.

    The California School Campus Database (海角乱伦社区) defines all known branch campuses. Aerial imagery, assessor parcel data, and school websites are used in researching campus locations.

  5. FLEXIBLE DATABASE DESIGN: 海角乱伦社区 has been structured to allow for expansion as well as joining of additional school attributes. All schools are identified by a unique CDS code allowing data users to readily join other information, so long as it has a CDS code. Geographically, schools are defined by the assessor parcel unless the school campus differs greatly, allowing for alignment with other layers such as parks and jurisdictional lands.
    6. An aerial basemap has map layers with: parks and open space data from CPAD (green), multiple public K-12 schools data from 海角乱伦社区 (yellow), and university campus data from 海角乱伦社区 (pink).

    The California School Campus Database (海角乱伦社区) can be used alongside university campus data and parks and open space. The use of assessor parcel data for alignment minmizes silvers and gaps in analysis.

USES

海角乱伦社区 has been developed to meet the needs of multiple users. Actual and potential uses include:

  • Distance to risk:
    • Retail of tobacco, alcohol, and other controlled substances
    • Drug free zones
    • Pesticide use and drift
    • Registered sex offenders
  • Evaluation of accessibilty of open space on school grounds for physical education and recess
  • Proximity to parks and open space for off-campus "joint use" policies, which make school grounds accessible as public parks during certain hours or seasons.
  • Opportunities for water recharge
  • Provide a geographic base geometry for an inventory of facilities
