Is the confirmation of homestead based on satellite positioning?

The village where we live and our home are all mapped by satellite positioning. The purpose of this is very long-term, and it is a serious blow to the overall planning of villages and towns and the illegal occupation of land for building houses, because under the satellite, there is nothing to hide. So many people will receive a notice that the homestead has been marked with a red line. Article 13 of the Measures for the Administration of Rural Homestead may apply for a homestead under any of the following circumstances: (1) It needs to be relocated or rebuilt due to national or collective construction, relocation or disaster; (two) the implementation of city, village and market town planning or the transformation of old villages, the need to adjust the demolition; (three) the existing homestead area has not yet reached the quota standard stipulated in these measures and needs to be rebuilt or expanded; (four) with household conditions and the original homestead area has not yet reached the limit standard stipulated in these measures, which needs to be rebuilt or expanded; (five) with the approval of the county people's government, the professional and technical personnel introduced or recruited by rural collective economic organizations really need to settle in rural areas; (six) retired workers, demobilized soldiers and overseas Chinese, their relatives, Hong Kong, Macao and Taiwan compatriots with legal documents to return to their original places to settle down; (seven) as otherwise provided by laws, regulations and rules.
