The Public Land Survey System (PLSS) is the surveying method developed and used in the United States to plat, or divide, real property for sale and settling. Also known as the Rectangular Survey System, it was created by the Land Ordinance of 1785 to survey land ceded to the United States by the Treaty of Paris in 1783, following the end of the ...
A Land Information System (LIS) is a geographic information system for cadastral and land-use mapping, typically used by local governments. [1]A LIS consists of an accurate, current and reliable land record cadastre and its associated attribute and spatial data that represent the legal boundaries of land tenure and provides a vital base layer capable of integration into other geographic ...
The origin of the geodatabase was in the mid-1990s during the emergence of the first spatial databases.One early approach to integrating relational databases and GIS was the use of server middleware, a third-party program that stores the spatial data in database tables in a custom format, and translates it dynamically into a logical model that can be understood by the client software.
GIS data represents phenomena that exist in the real world, such as roads, land use, elevation, trees, waterways, and states. The most common types of phenomena that are represented in data can be divided into two conceptualizations: discrete objects (e.g., a house, a road) and continuous fields (e.g., rainfall amount or population density).
The cadastre is a fundamental source of data in disputes and lawsuits between landowners. Land registration and cadastre are both types of land recording and complement each other. [2] By clearly assigning property rights and demarcating land, cadasters have been attributed with strengthening state fiscal capacity and economic growth. [4]
When computers began to be used for mapping and GIS, the state plane system's cartesian grid system and simplified calculations made spatial processing faster and spatial data easier to work with. Even though computer processing power has improved radically since the early days of GIS, the size of spatial datasets and the complexity of ...
Like the CGIS, early GIS installations in the United States were often focused on inventories of land use and natural resources, including the Minnesota Land Management Information System (MLMIS, 1969), the Land Use and Natural Resources Inventory of New York (LUNR, 1970), and the Oak Ridge Regional Modelling Information System (ORRMIS, 1973).
