Sphere of Influence – SCAG Region

This data contains the boundaries of the Sphere of Influence in the SCAG Region for the year 2019, updated as of January 7, 2022. The Sphere of Influence represents the geographic extent to which a city can expand by annexation. The original sphere of influence boundary data was obtained from county local agency formation commissions (LAFCOs)to reflect the most current updates and then was reviewed and cleaned up by SCAG staff. This data will be further reviewed and updated as SCAG continues to receive feedbacks from LAFCOs, subregions and local jurisdictions. Data-field descriptions: SOI_NAME: Sphere of Influence name COUNTY: County name COUNTY_ID: County FIPS Code CITY: City Name CITY_ID: City FIPS Code ACRES: Area in acres YEAR: Dataset year本数据集涵盖2019年南加州大都会规划协会（Southern California Association of Governments，SCAG）辖区内的势力范围（Sphere of Influence）边界数据，更新至2022年1月7日。势力范围指城市可通过行政兼并实现扩张的地理范围。原始势力范围边界数据取自各郡地方机构编制委员会（Local Agency Formation Commission，LAFCO），以反映最新更新内容，后经SCAG工作人员审核并清洗。后续随着SCAG持续收到来自LAFCO、各分区及地方辖区的反馈，本数据集将进一步开展审核与更新工作。数据字段说明如下： SOI_NAME：势力范围名称 COUNTY：郡名 COUNTY_ID：郡FIPS（Federal Information Processing Standards）代码 CITY：城市名称 CITY_ID：城市FIPS代码 ACRES：面积（单位：英亩） YEAR：数据集年份
