Document Summary

* lambeth moved it to cleaner source of water. * people started to listen to him when he published the paper that the contaminated water might be the cause. * broad street pump is where a lot of the incidences happened. Attribute (describing non- spatial properties of objects or tabular data) * how we can understand how to combine data in a better way. * access is useful for combining data and analyzing different data together. * in gis, there are two types of data: spatial and attribute (aspatial) * geometry (polygon) part is the spatial data. * information about polygons, areas, they are attributes = describe geometry. * when we are visualizing data on flat surface, we create polygons/ areas. * zooming into the spatial polygon = you will get coordinates (longitude, latitude) * attributes are not about geometric objects, but rather it is an actual information describing the objects.
