Question

Which technique is applied to identify point location in address geocoding?

a) Linear interpolation
b) Select by location
c) Spatial join
d) Intersect
e) Union

Answer 1

Linear interpolation is the technique used in address geocoding to estimate the geographic location of an address based on its position relative to known locations on a street segment.

Step-by-step explanation:

The technique applied to identify point location in address geocoding is linear interpolation. This method is used to estimate the geographic location of an address by using known locations along a street segment. Using this technique, the address is assigned a position on a linear street based on its relative address number between the known start and end points of the segment.

For example, if the known addresses at the start and end of a block are 100 and 200, and the address to be geocoded is 150, linear interpolation will place the new address halfway along the block, assuming uniform address spacing. This method does not account for uneven address distribution or physical geography, but provides a quick and standard estimation for mapping purposes.
