Shape_Length (polylines and polygons): The linear measurement of each feature.Polygon and Polyline layers all have at least one of the following fields:.It is impossible to have a shapefile which contains both polygons and polylines. Each and every record in a single shapefile or feature class will have the same shape. Attribute tables associated with vector data contain the geometry of that layer (point, polyline, polygon) under the field heading of “Shape”.If you tell ArcGIS to search for the name "California", it will not return any records where California is entered any other way except the way you typed it. It can only match what you type in a box to what it "sees" in a table. An attribute table will see these as three separate values, because remember, your computer is stupid and cannot read or comprehend. Record values are case sensitive and spelling dependent, meaning “california” is not the same value as “California” nor “Kalifornia”.Colorado only has one name (Colorado, FYI), so the only thing which will appear in the NAME field for the row which corresponds with the Colorado shape on the map is Colorado. This means that for each feature, there is only one record for each field. Each cell (where the row and field intersect) contains one and only one value, or record.This means each column (field) has a unique name made up of only letters and numbers and cannot have any spaces. Each field has a heading (name of the field) which is made up of alpha-numeric characters only and has no spaces. ![]() For example, all the pixels which are classified into the urban category are represented with one row in the attribute table. This means that raster files have attribute tables, too, but instead of one row for each pixel, each group of pixels have a row. ![]()
