Add Survey Term to Almanac

Land Surveyor's Almanac is an ongoing community project to crowdsource surveying definitions and terms with examples for the next generation land surveyor to learn from. If you are a Land Surveyor, add a term to the Almanac with its definition and examples. Help improve the collective knowledge of the community by improving upon terms added by other surveyors by commenting with your examples and applications in your local surveying environment.

What is Spatial Data?

What is Spatial Data?
Spatial data, also known as geospatial data, is a term used to describe any data related to or containing information about a specific location on the Earth’s surface.The BasicsSpatial data can exist in a variety of formats and contains more than just location specific information. To properly understand and learn more about spatial data, there are a few key terms that will help you become more fluent in the language of spatial data.VectorVector data is best described as graphical representations of the real world. There are three main types of vector data: points, lines, and polygons. Connecting points create lines, and connecting lines that create an enclosed area create polygons. Vectors are best used to present generalizations of objects or features on the Earth’s surface. Vector data and the file format known as shapefiles (.shp) are sometimes used interchangeably since vector data is most often stored in .shp files.RasterRaster data is data that is presented in a grid of pixels. Each pixel within a raster has a value, whether it be a colour or unit of measurement, to communicate information about the element in question. Rasters typically refer to imagery. However, in the spatial world, this may specifically refer to orthoimagery which are photos taken from satellites or other aerial devices. Raster data quality varies depending on resolution and your task at hand.Raster data is data that is presented in a grid of pixels.
