What spatial data contains?
Spatial data comprise the relative geographic information about the earth and its features. A pair of latitude and longitude coordinates defines a specific location on earth. Satellite images, photographs, scanned images, etc., are examples of raster data. Vector data are composed of points, polylines, and polygons.
What is a spatial data pattern?
Spatial point patterns can be broadly grouped into random or nonrandom processes. Real point patterns are of- ten compared with random patterns (generated by a Poisson process) using the average distance between a point and its nearest neighbor. Lattice: A lattice is a model for a gridded space in a spatial framework.
Is an example of spatial data?
Examples of geospatial data include: Vectors and attributes: Descriptive information about a location such as points, lines and polygons. Census data: Released census data tied to specific geographic areas, for the study of community trends. Cell phone data: Calls routed by satellite, based on GPS location coordinates.
Why is the spatial context of cancer important?
Spatial Context of Cancer The spatial context in which people conduct their every day lives encapsulates a person’s multiple interactions with the social and physical environment that may have lasting health impact.
Where does the US cancer statistics come from?
The United States Cancer Statistics (USCS) are the official federal cancer statistics. They come from combined cancer registry data collected by CDC’s National Program of Cancer Registries and the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) program.
Where can I find data on cancer incidence?
Researchers can access and analyze high-quality population-based cancer incidence data on the entire United States population. De-identified cancer incidence data are available to researchers for free in public use databases.
Why is it important to understand spatial context?
Because many cancers develop over a long period of time, knowing the spatial context throughout a person’s life is important to understand his or her total exposure to toxic agents. Exposure to chemicals in the air can increase cancer risk. Such chemicals include industrial, auto, agricultural, asbestos, and pesticides.
